What Is Emergency Heat and When Should I Use It?

Written by Kevin on November 5, 2025. Posted in HVAC.

When the temperature drops, you rely on your heat pump to keep your home warm. You may have noticed a setting on your thermostat labeled “Emergency Heat” or “EM Heat.” It’s a feature many don’t fully understand, and as a result, it’s often ignored entirely or used incorrectly. You may need to activate it manually if your heat pump malfunctions. Here, we’ll explain what emergency heat does, when you should activate it, and when to leave it off. This will help you avoid high energy bills, prevent unnecessary wear on your system, and keep you warm.

How Heat Pumps Normally Work

Unlike a furnace that generates heat, a heat pump transfers heat from one place to another. This is an extremely energy-efficient method for heating your home. In heating mode, the system extracts heat from the air outside and transfers it indoors. Even in cold weather, outdoor air contains enough thermal energy for the heat pump to work efficiently.

In Sterling’s climate, heat pumps handle most of the heating load well for much of the year. However, as temperatures dip well below freezing, the system’s ability to extract heat decreases. While a cold-climate heat pump can work efficiently down to around 15 degrees below zero, standard heat pumps feature auxiliary heating.

What Emergency Heat Does

Emergency heat is a backup system for your heat pump. This is for when your heat pump malfunctions. You manually tell the system to stop using the outdoor unit entirely and rely only on the secondary heating source. This secondary source is typically either electric resistance heat strips installed inside the air handler or a furnace.

This mode bypasses the heat pump’s outdoor components. Since emergency heat is less energy efficient, using it for extended periods can result in significantly higher utility bills.

Emergency Heat vs. Auxiliary Heat

It’s easy to confuse emergency heat with auxiliary heat, but they’re not the same. Auxiliary heat automatically turns on when the heat pump alone can’t keep up with the home’s heating demand. For example, if the temperature outside drops, the heat pump may need extra help maintaining the set indoor temperature. The thermostat will signal the backup heat source to kick in temporarily. Once the temperature stabilizes, the auxiliary heat turns off, and the heat pump takes over again.

Emergency heat, on the other hand, requires you to manually switch the thermostat to EM Heat. Doing this tells the system to shut off the heat pump and rely only on the backup heat source. You should only use this setting under specific circumstances, which we’ll cover next.

When You Should Use Emergency Heat

Emergency heat is important, but it is not meant for everyday use. You should only activate this mode under certain conditions.

When the Heat Pump Breaks Down

Use emergency heat if your outdoor heat pump unit stops working due to a mechanical issue, electrical failure, or a refrigerant problem. This ensures your home doesn’t go without heat. By switching to EM Heat, you rely on the backup system until a technician can repair the unit. This can be a lifesaver during freezing temperatures. You stay comfortable and avoid frozen pipes and other cold-weather problems.

When Ice Accumulates on the Outdoor Unit

Heat pumps typically defrost themselves automatically, but severe winter storms can sometimes overwhelm this function. When ice builds up on the outdoor coils, the system may shut down to protect itself. Switching to emergency heating keeps your home warm while preventing further damage to the equipment.

When Extreme Cold Overwhelms the Heat Pump

Sterling winters can bring cold temperatures that are well below the heat pump’s efficient operating range. In these rare cases, switching temporarily to emergency heat may keep your home more comfortable. However, it’s usually better to rely on auxiliary heat or a properly configured dual-fuel system.

When You Should Avoid Using Emergency Heat

Since emergency heat often uses electric resistance coils, it consumes far more energy than normal heat pump operation. Leaving it on unnecessarily can cause your utility bills to skyrocket. Avoid switching to emergency heat if your heat pump is working normally and only requires auxiliary support during a temporary cold spell.

You should also avoid using it to try to heat your home faster. EM Heat doesn’t speed up heating; it just forces the system to rely on a more expensive backup source. Don’t use this mode if you haven’t confirmed that the heat pump is malfunctioning. You shouldn’t use the emergency setting unless there’s a clear reason to bypass the outdoor unit entirely.

How Emergency Heat Fits Into Dual-Fuel Systems

You can also use dual-fuel systems, which use a gas furnace as well as a heat pump. These systems switch between the two heat sources to maximize efficiency. In mild weather, the heat pump will provide energy-efficient heating. When temperatures drop to a set balance point, the system turns off the heat pump and lets the furnace take over. This transition happens automatically and is often more cost-effective than using electric resistance backup.

Emergency heat in a dual-fuel system typically refers to manually switching the thermostat to run the furnace exclusively. This might be necessary if the heat pump breaks down and needs emergency service. Since natural gas furnaces generally cost less to run than electric resistance heating, dual-fuel setups offer a cost-effective and reliable backup solution.

The Cost Implications of Using Emergency Heat

Emergency heat keeps you warm in a pinch, but it comes at a cost. Electric resistance heating uses far more energy than a heat pump. A heat pump can deliver two to three units of heat for every unit of electricity consumed. A resistance heating method delivers one unit of heat for each unit of electricity.

If you run emergency heat for days at a time, your utility bill can climb rapidly. Dual-fuel systems eliminate this problem by switching to gas heat instead of electric strips. Even then, running the system in emergency mode unnecessarily is not ideal. If you find yourself relying on EM Heat frequently, it may be a sign that your heat pump needs service. Alternatively, your home’s insulation may need improvement, or your system may not be sized correctly for your home.

The Role of Professional Maintenance

Routine maintenance is important when it comes to preventing the need for emergency heat. A well-maintained heat pump can handle colder temperatures more efficiently, defrost itself properly, and run reliably throughout the winter. [company_name] recommends scheduling annual heating system maintenance before the winter season begins. During a maintenance session, our team will check refrigerant levels, clean coils, and inspect electrical components. We also test defrost cycles and verify that backup heating functions correctly.

Smart Thermostats and Emergency Heat

Many newer thermostats and smart controls automatically detect when your heat pump needs auxiliary or emergency heat. They can send alerts when something goes wrong, allowing you to act quickly before issues have the chance to escalate. Smart thermostats also make it easier to manage dual fuel systems. They will switch between the heat pump and the furnace based on the outdoor temperature. This ensures that you always use the most cost-effective option without manual intervention.

Preparing Your Furnace For The Winter

Written by Kevin on October 15, 2025. Posted in HVAC.

Winter in Sterling, VA can be brutal with frigid temperatures and snow. Your heating system should bring you comfort and safety from these extremely low temperatures. With our help at [company_name], we can keep your furnace running optimally so that it works flawlessly all winter long. Our technicians perform comprehensive heating system maintenance, which we have outlined for you.

Performing Visual Inspection

Our certified technicians inspect all the inner parts and components of your heating system during seasonal maintenance. We look at the blower motor, fan, and belts for damage and malfunction. We check that all parts are secure. As we inspect, we look for signs of abnormal conditions and excess wear and tear that could signal a bigger issue. Our technicians use the inspection process to diagnose problems early before they cause your system to stop in the middle of the season when you need it most.

We can make some minor repairs during our maintenance visit. However, for more complex issues, we may need to schedule a follow-up visit to get your system up to speed. For this reason, it’s crucial to schedule your service as early in the fall as possible. With enough time, we can perform maintenance and come back for all repair work before the cold temperatures arrive.

Cleaning Interior Components

Throughout the year, dust and debris accumulate inside your heating system. This buildup can cause stress on your system by adding weight to moving parts and getting in the way of proper function. Our technicians clean the inner components of your heating system as we work through the inspection and tuning process. Removing these contaminants can also improve the air quality in your home. Without the excess dust, allergens, and other contaminants inside your heating system, you’ll find fewer contaminants circulating through your home.

Lubrication of Moving Parts

Some of the internal parts of your heating system move during operation. To prevent damage caused by the friction of this movement, our technicians lubricate these parts. Without proper lubrication, certain parts, such as bearings, pistons, and motors, may fail more quickly due to the stress of friction.

Gas and Electrical Check

If you have a gas furnace, we’ll pay special attention to the gas lines, valves, and other related components. We will inspect your gas lines for leaks or damage and make sure they are securely connected. We check the gas valve and make sure it is open to allow gas to flow to your furnace. We also test gas pressure, ensuring it is within normal operating limits to prevent unsafe conditions. Our technicians will check your furnace’s pilot light and light it if it has gone out. The pilot light should burn bright blue, which indicates the presence of gas. A yellow pilot light may mean that gas is not flowing to the system, indicating a lack of flow or a leak.

We also check electrical connections on both gas and electric heating systems. We make sure all wiring is secure and damage-free. We look for frayed wires and loose connections, which could lead to shocks and electrical fires.

Safety Feature Test

Most heating systems have safety switches or features that keep you and your household safe. These safety mechanisms shut your system down when they detect unusual or unsafe conditions, such as overheating or the presence of carbon monoxide. Stopping a heating system during malfunctions can prevent damage to the furnace and reduce the risk of danger in your home. If any of the safety features fail, we’ll need to perform repairs before your system can be operated safely.

Running a Test Cycle

Once we’ve finished cleaning, inspecting, and tuning up, we’ll turn on the heater and run a couple of test cycles. During these cycles, we check all the vents throughout the house for even and sufficient airflow. We make sure the air coming from the vents is warm and can bring your house to the set temperature on your thermostat.

We’ll also listen to strange noises and check for unusual odors that could indicate an issue inside the heating system. If we find problems during the test cycles, we’ll go back to the internal components to find the cause. Our technicians always ensure your system works perfectly before we complete our annual maintenance visit. The only exception to this is if we need to follow up with repairs.

Make sure you run your heating equipment prior to the start of cold weather. Waiting until temperatures drop can leave you without heat if something malfunctions.

Changing Your Filter

You should adhere to a schedule of changing your filter every 30 to 90 days. This process protects the interior components of your HVAC system and improves the quality of your indoor air. It’s a good idea to change your filter prior to the start of cold weather when you’ll be using your heating equipment often.

Clean Vents and Registers

Wipe down your vents and registers, which often experience an accumulation of dust and debris as time goes on. This process can prevent particulate matter from accumulating inside your HVAC system and ductwork, leading to system strain. You can promote healthy indoor air quality with this pre-season routine maintenance.

Consider Your Thermostat Settings

Assess your thermostat settings before the start of cold weather. Most thermostats allow you to program your preferred temperature settings for certain days and times. Your daily routine may have changed since last year. Also, consider making adjustments that can reduce your energy consumption. Dropping the temperature in your home when you’re away for the day or sleeping can save a lot of money.

Consider upgrading to a smart thermostat prior to winter. These devices provide features such as remote control, learning capabilities, and geofencing technology. There are often rebates and incentives that can offset the cost of investing in a new smart thermostat.

We may need to calibrate your thermostat during routine maintenance. This ensures you have access to accurate temperature readings to support optimal comfort and efficiency.

When Should I Call for Heating Maintenance?

Our experts recommend scheduling heating maintenance in Sterling every fall. The earlier you schedule your service, the more time we have to address your system if repairs are needed. Chilly temperatures, especially at night, often arrive later in the fall, well before the official start of winter. Make sure your system is ready before you need heat by scheduling an appointment with us at the start of fall or in late summer.

When Is The Cheapest Time To Install A New HVAC Unit?

Written by Kevin on September 16, 2025. Posted in HVAC.

Investing in a new HVAC system is a major expense. It’s smart to take your time and plan accordingly to try and achieve an affordable price. This may not be possible if your system experiences a complete breakdown with no warning. Taking time to research a new HVAC system can help you save a significant amount of money. We here at [company_name] are available to help you with the selection of a new unit as well as installation support.

Will Maintenance and Repairs Help Me Postpone Replacement?

It’s possible that professional maintenance and repairs can help you increase your HVAC system’s lifespan. This is particularly crucial if you know your system is nearing the end of its life, but you still aren’t in a financial position to get a new one.

Changing the filter regularly is one of the most important things you can do for your HVAC system. This helps prevent the system from experiencing strain, which can lead to a decreased lifespan. If you’re unsure what filters you need or how to change yours, ask our team for guidance. Some systems use a reusable filter. In this case, you clean it rather than replace it. Choose a filter that is between 8 and 12 MERV. The minimum efficiency reporting value (MERV) scale ensures you’re not restricting airflow through your system, which can cause system issues.

Periodically remove weeds, branches, and debris away from outdoor HVAC equipment. You should maintain several feet of clearance around your equipment, allowing for proper airflow. This prevents equipment strain and keeps plants and sticks from getting into the system and damaging important components.

When Is the Best Time of Year to Install an HVAC System?

Summer and winter are peak heating and cooling seasons. This means that the fall and spring are considered off-peak, making them the ideal seasons to schedule an installation. This doesn’t just save you money. You may also have access to a larger pool of appointment dates and times that better coincide with your schedule.

Can I Save Money by Installing the System Myself?

An HVAC system needs to be installed professionally to function safely and efficiently. Our team consists of skilled professionals who have extensive experience installing these appliances, allowing them to know exactly what to do in a wide range of situations. The installation process can be much more challenging for those who don’t have the same level of training and experience. It’s easy to make costly mistakes, such as damaging the new equipment before it’s in use.

Choosing the do-it-yourself route may lead to our team coming to your home to perform repairs if you accidentally made a mistake. Severe damage might require a replacement of the equipment you just purchased. There are also safety risks involved with DIY work. Working with a professional also ensures the warranty coverage of your HVAC system remains valid. If something malfunctions with your equipment early on, you don’t want to be financially responsible.

Are There Specials or Promotions Available Throughout the Year?

There are no guarantees that specials or promotions will be available on our website throughout the year. However, we encourage you to check out our “Specials” page and browse the rest of our website for possible deals. We will work with you to determine the type of unit you need for your home, considering your heating and cooling needs as well as your budget.

How Far in Advance Should I Start Researching an HVAC System?

It’s never too early to start researching the type of HVAC system you want to get. This will give you ample time to compare prices, read reviews, and determine the best option for your home. Starting too close to the installation date may cause you to rush your decision. This increases your risk of choosing a system that doesn’t meet your needs or preferences or that’s out of your price range.

Does the Type of HVAC System Impact the Installation Costs?

The type of HVAC system you choose can impact the installation costs. The work we need to do during the project can also influence the price. For instance, if you want to install a zoned system or heat pump, the costs will increase for every additional unit you want us to install. If you opt for central AC, the price will go up if we need to install or modify ductwork. Our team can discuss what HVAC options would be ideal for your home, needs, and budget, so you can make an informed decision about which option is best for you.

Can Early Planning Help Me Avoid Emergency Costs?

An HVAC system breaking down can force you to make a fast decision about a replacement. This is especially true during times of extreme weather, such as summer or winter. Rather than taking the time to do your research, you’ll have to rush the process. After all, replacement is in the best interest of your comfort and safety. Depending on the severity of the issue, we may be able to perform a repair to give you more time. However, this is a temporary solution, especially if your HVAC system has surpassed its expected lifespan.

How Do I Know I’m Getting a Good Deal?

Taking time to do research is the best way to know if you’re getting a good deal. Compare prices and reviews so you have an idea of what your options are and how to get the most for your money.

How Do I Know If Replacement Is Necessary Immediately?

If your system seems to be working perfectly, you are likely to have some time before you need a replacement. However, there are no guarantees, especially with an aging system. It’s better to start the research process early so you’re ready to make your installation appointment during the off-season without having to rush. This also saves you money and time.

Are There Situations Where I Can’t Wait?

Scorching summer and frigid winter temperatures aren’t times when you want to be without a working HVAC system. This is especially true if people in your home have chronic health conditions, you have small children or elderly people in your home, or you have pets. As much as you might want to wait until the off-season to save some money, it’s not worth your health or safety.

How Much Does an HVAC Unit Cost?

The cost of an HVAC unit can vary based on several factors, such as its type. Keep in mind that the final price includes more than just the unit. There are also other costs involved, such as labor. We recommend creating a budget for what you can spend. Leave room for unexpected modifications or repairs.

Indoor air quality services in Sterling, VA

How Do I Test My Home’s Indoor Air Quality?

Written by Kevin on June 2, 2025. Posted in HVAC.

Air quality in many homes is often several times worse than it is in the surrounding outdoor air. Consequently, indoor air quality testing is an important part of maintaining a healthy environment in your home. Testing and responsive measures can also extend the lifespan of your home’s HVAC. However, you may wonder what is the best way to test indoor air quality. Here, we have some answers.

The Case for Professional Testing

Off-the-shelf indoor air quality testing kits are available for DIY purposes. However, they almost always lack the range of tests needed to fully understand why your house might have poor indoor air quality. Professional testing systems can check for a host of potential problems.

Notably, consumer tests usually only detect particulate matter down to 2.5 microns (PM2.5). A MERV 13 filter, which most home HVAC systems can handle, can trap up to 85% of particulates of that size. Things smaller than 2.5 microns aren’t visible to the human eye, and they often need to be treated with something like UV light rather than filtration. Also, you usually need a separate text or device to measure humidity levels.

When it comes to gases, consumer tests frequently have much higher false-positive and false-negative rates. This makes it hard to be confident that a particular reading is relevant.

Some kinds of consumer kits only provide safety alerts. For example, most consumer carbon monoxide tests don’t provide a precise reading. Instead, they simply inform you that the carbon monoxide level is unsafe.

Additionally, to enact indoor air quality solutions, you’ll need to loop in an HVAC technician at some point. Our technicians are going to want to perform their own tests before they recommend anything. It is often easier to skip the home kit step and leave the testing to us. This reduces confusion, especially if a consumer test contradicts what our sensors are showing.

We can test a variety of issues on-site. Additionally, send out for lab testing and get highly accurate results back, usually within a week.

What Professional Tests Look For

Among the toughest things to test for on your own are volatile organic compounds (VOCs). These are chemicals like formaldehyde and benzene that appear frequently in an astonishing range of modern products. For example, many building products like wood have VOCs left over from the treatment process. These chemicals keep the wood from rotting, especially when it sits in lumber yards. However, the chemicals take years to leach out, meaning they often end up in homes.

Also, many household products emit VOCs. Perhaps the most perplexing thing to think about is that many air fresheners include VOCs. Yes, every time you spray to make your home’s air smell fresher, there is a good chance it’s reducing the indoor air quality. Lots of other products emit VOCs, including cookware, carpeting, house paints, nail polish, and hairspray.

Mold spores are another major target of indoor air quality testing. Mold can grow in environments where the relative humidity level stays above 60 percent. Even if your home has a whole-house dehumidifier, there may be spots where humidity concentrates at high levels and encourages mold spores. The mold can then spread around your home, leading to extra dust and odd smells. In the worst cases, mold will also cause respiratory irritation that can aggravate allergies or asthma, trigger runny noses, and encourage sore throats and coughing.

Taking samples to test for mold also allows us to search for other potential pathogens, such as bacteria and viruses. If you or someone in your household is regularly getting sick without an explanation, this could be the cause.

Humidity levels are worth checking, and not just to discourage mold growth. The optimal humidity range in a home should be between 30 and 50 percent. This is low enough to stop mold growth while also staying high enough to discourage dry air. Dry air can cause problems like red eyes, skin irritation, and respiratory problems. The solution is often to add a whole-home humidifier, especially if your home includes a forced-air furnace that dries the air during the winter.

Carbon monoxide and dioxide tests are also important. Carbon monoxide can accumulate in a home from spent fuels, particularly from gas heating systems and gas stoves. It is colorless, odorless, and tasteless, but carbon monoxide can be lethal. Carbon dioxide has also risen as a source of recent concerns, particularly because high CO2 levels can trigger fatigue and brain fog.

Reporting

Once we have collected all the data, our technicians will provide you with a report. We will identify the overall concentration levels of specific indoor air quality problems. Likewise, we will note any specific trouble areas we see. Our technicians can note some of the specific health issues that are likely to arise from what we found, too. We will present our findings and discuss potential HVAC solutions.

When to Test Indoor Air Quality

Presuming that you have no specific reason to arrange an indoor air quality test, the best schedule is going to be about once every three years. The notable exception is if you’re moving into a newly constructed house. This is because new houses suffer the most from off-gassing of VOCs, so you should schedule a test within the first year.

There are specific scenarios where you should schedule testing immediately. If your house recently experienced humidity problems or water damage, then you need to be sure that it doesn’t have mold issues. Even if there haven’t been recent issues, order a test right away if you detect musty smells or other indications of mold. Something as simple as a slowly declining HVAC may lead to higher humidity levels in your home.

Possible Solutions

The good news is that there are usually plenty of ways to treat poor indoor air quality. Striking the right balance in humidity levels often requires adding both a humidifier and a dehumidifier. This is because our region frequently experiences hot and wet summers but suffers from dry winter air.

Upgrade filtration is another common option. Our technicians can determine whether your HVAC supports it. If not, we can install a separate high-grade whole-house air filtration system. UV light is an option for treating biological agents. Activated carbon filtration is sometimes a good choice for neutralizing many kinds of VOCs, other chemicals, and bad smells.

Can You Claim IRS Tax Credits After Installing a New Heat Pump?

Written by Kevin on April 1, 2025. Posted in HVAC.

The Inflation Reduction Act in 2022 includes key provisions to make American homes and businesses more energy efficient. The provisions give property owners opportunities to save money on specific upgrades that improve energy efficiency. The previous Residential Clean Energy Credit offered by the Internal Revenue Service (IRS) focused mostly on solar energy and geothermal systems. The 2022 act expands the upgrades to cover more equipment, including heating, ventilation, and air conditioning (HVAC) solutions.

Heat pumps are on the list of HVAC equipment marked by the Inflation Reduction Act for federal tax credits. This is a 10-year plan with gradual implementation, so the credits for heat pumps are new. The credits started on Jan. 1, 2025; however, not all brands or models qualify.

Understanding the New IRS HVAC Tax Credits

Essentially, the Inflation Reduction Act introduces and modifies various tax credits that lower the carbon footprint of American residential and commercial properties. These credits aim to incentivize home and business owners to adopt sustainable, energy-efficient practices.

Regarding HVAC, the Residential Clean Energy Credit (25D) started with geothermal heat pump systems. The expansion to electricity-powered heat pumps is covered by the new Energy Efficient Home Improvement Credit (25C). The improvements now include many air-source heat pumps that meet specific criteria. Other 25C improvements include energy audits, insulation, and weather stripping of exterior-facing doors and windows. The credit has specific requirements for the efficiency ratings of the equipment and materials. Here, we will focus on residential HVAC solutions that qualify for the new 25C credit.

Tax credits for installing heat pumps are subject to annual aggregate limits. The total annual credit limit is $3,200. There’s a $1,200 limit for combined expenses, which may include windows, doors, skylights, and insulation. With heat pump systems, including those that pair with a furnace, the annual aggregate limit is $2,000. the credit does not apply to properties that the IRS designates as second homes. The credits are only for primary residences, not vacation homes or rentals.

You can plan energy-efficient upgrades to maximize your tax credits over multiple years. Since there are annual limits, spreading them would allow you to claim more overall. Let’s say you plan on replacing an old HVAC system with a heat pump. The best way to claim the credit would be to first improve your attic insulation, thus reducing energy waste. This strategy lets you claim up to $1,200 for insulation and $2,000 for the heat pump in the same year.

You can also combine a heat pump installation with window and door replacements. With this strategy, you can get $2,000 for the heat pump and up to $600 for windows and skylights. You would have $500 worth of credit left to claim for adding weather stripping to the doors. You could replace your water heater the next year, thus claiming another 30% credit up to $2,000.

The IRS sets efficiency standards to qualify for these tax credits. Not all heat pumps meet them. Certified professionals must install the qualified equipment, so [company_name] can take care of this requirement. There are limits on how much you can claim, both annually and over the lifetime of the credit. You must keep records of purchases and installations to support any tax credit claims.

Which Heat Pumps Qualify for the 25C Tax Credit?

Air-source heat pumps are now within the purview of the credit. Since Jan. 1, 2025, you have been able to claim tax credits for highly efficient systems. To qualify, the unit must have an ENERGY STAR Most Efficient certification. This includes equipment designed for cold climates (ENERGY STAR Cold Climate) and systems paired with a furnace. You can choose either heat pump type in Northern Virginia because the new credit eliminates previous regional restrictions.

ENERGY STAR Most Efficient Heat Pumps

The Most Efficient certification represents the pinnacle of energy efficiency for each product category. For air-source heat pumps, the certification means the unit surpasses ENERGY STAR standards. The designation is for heating and cooling.

The U.S. Environmental Protection Agency (EPA) sets the criteria for energy-efficient heat pumps. The factors include the seasonal energy efficiency ratio (originally SEER, SEER2 since Jan. 1, 2023), heating seasonal performance factor (HSPF), and coefficient of performance (COP). With these metrics, the EPA measures the efficiency of HVAC systems for energy savings.

SEER2 measures the cooling efficiency of a heat pump over a typical cooling season. A high SEER2 is what you want to see when selecting a heat pump that would qualify for the 25C credit. HSPF measures the heating efficiency over an average heating season. A higher HSPF means improved performance and lower energy consumption. COP is a performance ratio at specific operating conditions. It essentially shows how heat pumps perform with each unit of electricity consumed.

Variable-speed or inverter-driven heat pumps are more likely to receive ENERGY STAR Most Efficient certifications. With this advanced technology, heat pump systems modulate their operating speed to match the precise heating or cooling demand. This eliminates the on/off cycling of single-speed compressors, thus delivering consistent temperatures and reducing energy waste.

By operating at lower speeds for extended periods, variable-speed heat pumps promote higher efficiency during partial-load conditions. New heat pumps are invariably equipped with smart thermostats, thus making the variable-speed mechanism more precise and efficient.

ENERGY STAR Cold Climate Heat Pumps

This program issues a certification that addresses the unique challenges of heating in regions with consistently low temperatures. Our service area has experienced harsh winters in recent years, and this climate trend will likely continue. The certification goes beyond the standard ENERGY STAR requirements for subfreezing conditions.

An ENERGY STAR Cold Climate-certified heat pump can extract heat from the outside air even when temperatures dip below freezing. Enhanced compressor designs improve heat exchangers and incorporate sophisticated control systems. Traditional heat pumps lose much of their heating capacity as temperatures drop. Some of our past clients with legacy heat pumps were forced to get space heaters for the bedrooms. This electric-resistance heat solution goes against the principles of energy efficiency. Cold Climate heat pumps eliminate this issue.

To qualify for Cold Climate certification, heat pumps must deliver high HSPF values, particularly in cold temperature test conditions. This ensures that the heat pump can deliver heat throughout the winter while reducing energy consumption. These systems typically have advanced defrosting systems to prevent frost from forming on the outdoor coil. Variable-speed compressors are crucial for Cold Climate heat pumps; they allow the system to match the smart thermostat settings.

With more than three decades of HVAC experience, [company_name] offers a full range of heating service solutions to homeowners in Northern Virginia. Our Lennox product line includes various heat pump models that qualify for the federal 25C and 25D tax credits. To make your heat pump investment more advantageous and convenient, we offer maintenance service agreements on all HVAC systems. We are your top choice for HVAC installations, upgrades, maintenance, and repairs.

Whole-Home Dehumidifier vs. Whole-Home Humidifier: What is Best for You?

Written by Kevin on February 1, 2025. Posted in HVAC.

Relative humidity is the density of water vapor in an area and takes into account the temperature of that area. The relative humidity in your home should be between 35% and 50%. If you’re struggling to maintain a safe and comfortable level of relative humidity in your home, whole-home humidifiers and whole-home dehumidifiers can simplify the process. Comparing the two will help you decide which is the better option for your home. In some cases, investing in both units is beneficial.

Considering Local Climate

The weather and climate in Sterling, VA can vary quite a bit over the year, including the humidity, which can vary greatly depending on the weather. The humidity levels in your home can also be affected by actions like bathing, cleaning, and cooking. If you aren’t using proper ventilation, relative humidity levels can rise quickly.

This is a scenario when both a whole-home dehumidifier and a whole-home humidifier may be necessary. There may be days when one unit will need to run. Days later, the other unit will be necessary.

About Whole-Home Units

Both humidifiers and dehumidifiers are sold in stores as portable models. You simply plug these units in and move them from one room to another. While this is convenient, you aren’t addressing the humidity of your home as a whole. Installing whole-house units will remove or add moisture to all the air passing through your HVAC system while it runs. You don’t have to worry about moving your unit from one room to another. Whole-house humidity control also requires minimal maintenance.

Whole-Home Humidifiers

If the relative humidity of your home is less than 35%, you may experience dry and irritated sinuses. This can cause an increase in illness and infections. Your skin and hair may feel dry as well. You could also experience static electricity as you move from room to room. You can add small amounts of moisture back into your air, increasing the overall comfort and function of your residence. You control your whole-home humidifier using your thermostat, which also provides real-time humidity data.

Whole-Home Dehumidifiers

It’s incredibly important that you don’t allow humidity levels to rise above 50% in your home. High levels of humidity can make your home feel very uncomfortable. It can even feel like it’s hard to breathe if it’s hot in your home and humidity is climbing. In some instances, your home may be overly humid in the winter as well. If you’re doing a lot of cooking or cleaning, humidity quickly rises. You have exhaust fans in your bathrooms and kitchen that help expel some of that humid air to the outside. Make sure that you’re running them when necessary.

A whole-home dehumidifier can remove moisture from your indoor air as it passes through your HVAC system. The collected moisture will run through a condensate drain. You don’t have to worry about emptying any kind of collection tank; just check periodically that your drain line doesn’t appear to be clogged with mineral deposits or debris.

Choosing a Whole-Home Humidity Control Device

If you’ve decided that you want to invest in a whole-home dehumidifier, whole-home humidifier, or both, there are some things to consider when choosing your unit. First, think about the square footage of your home. Equipment that is too large for your home will be inefficient and simply drive up your energy bills. A unit that is too small will make it hard to manage your indoor humidity, and not only will that lead to reduced comfort but also could strain the system unnecessarily. The unit will have to work harder to keep the indoor humidity levels at a safe and healthy level.

Using a hygrometer, you can check the levels of humidity in different rooms of your home. You will want to check these levels at different times of the day and year. The data you collect will determine whether you need to remove moisture, add it back in, or both, depending on the conditions in your residence.

Scheduling Routine Maintenance

Your humidity control devices should be inspected once per year. This inspection can be added to your routine HVAC appointment for convenience. Certain maintenance tasks may be needed at this appointment. This includes cleaning the drain line for your equipment to ensure proper water flow. If water is pooling up near your HVAC system, this can cause corrosion and even mold growth.

There may be filters that need to be changed every few months. We will also inspect your water line, ensuring that it is functioning properly.

Inspecting the exterior of your equipment as well as interior components can alert our team to any issues that may be occurring. We can make any necessary repairs to protect the integrity of your humidity control equipment. We will also check your humidistat to ensure it provides accurate readings. If the readings are inaccurate, this could cause the wrong equipment to turn on, preventing proper humidity control.

There is an evaporator pad that many types of dehumidifiers use. This pad should be changed every one to three months. We can inspect your pad and let you know how often to change it.

Benefits of Whole-Home Humidity Control

We’ve touched on the importance of controlling indoor humidity. Whole-home equipment can help you achieve the desired levels of relative humidity between 35% and 50%. This will make your home feel more comfortable. It can also improve your indoor air quality. Very humid air can hold onto larger particulate matter. As this material circulates through your indoor air, it can lead to an increase in allergies, asthma attacks, and respiratory issues. As mentioned, dry air can be very irritating to your body as well.

If humidity levels in your home are too high or low, this can cause you to run your HVAC system more frequently, making your home feel warmer or cooler. When you run your HVAC system less, this results in less energy consumption and lower utility bills.

Ideal humidity levels in your home can protect your furnishings, flooring, and fixtures. If humidity levels are rising and falling frequently, this can cause wood flooring to expand and contract often, leading to warping and other damage that is difficult to fix.

If you would like to learn more about using a whole-home dehumidifier or humidifier, [company_name] can provide you with more information. We also install, repair, and provide routine maintenance for different types of heating and cooling systems.

Signs That Your HVAC Air Compressor Is Bad

Written by Kevin on December 13, 2024. Posted in HVAC.

A bad compressor in an air conditioner or heat pump is one of the worst issues an HVAC system can have. That’s because the compressor is the most important component in either of these units. If the compressor completely fails, you’ll no longer be able to cool or heat your home. Some signs of a bad compressor are fairly easy to spot and are something you’ll realize almost immediately. Others are more difficult since they can be related to other issues.

Understanding the Role of an HVAC Compressor

The compressor in an AC or heat pump serves two essential roles. It’s responsible for pumping refrigerant through the system so that it flows to the evaporator coil before eventually flowing back to the unit outside. Also, it compresses the refrigerant, which is an essential step in the cooling cycle.

As the system runs, the refrigerant continually goes through a cycle where it changes from a cold, low-pressure liquid into a hot, high-pressure gas. This process is only possible because the compressor compresses the refrigerant so that its pressure greatly increases, and it immediately boils and turns into a gas. The refrigerant starts out as a cold liquid, which allows it to capture heat from the air inside the house as it moves through the copper tubes in the evaporator coil. It then travels back outside where it gets compressed before flowing through the tubes in the condenser coil. Compressing the refrigerant is essential since it causes it to become much hotter than the air outside. This allows all of the heat to be released. The refrigerant then changes back into a cold liquid.

This same process is also what allows heat pumps to capture heat from the outside and transfer it into the building. The only difference is that it works in reverse, meaning the refrigerant flows in the opposite direction and gets compressed before being pumped inside.

AC or Heat Pump Won’t Turn On

If the compressor completely fails, it will result in your AC or heat pump not turning on. This can happen for a variety of other reasons, too, such as a bad contactor relay switch or start capacitor. It could also mean there’s an electrical issue preventing power from flowing to the unit or even an issue with the thermostat not signaling the unit to turn on as it should. The only way to know for certain whether you’re dealing with a failed compressor is to have a technician perform an inspection and diagnostic assessment.

Unit Keeps Tripping the Circuit Breaker

There are really only two main reasons why an HVAC system will frequently trip the circuit breaker. The first is that there is some type of electrical fault somewhere in the system, like a loose or damaged wire. In this case, the system short circuits and causes a power surge that trips the breaker.

The second reason is that the compressor motor, the condenser fan motor or the blower motor is starting to give out. It takes a massive amount of power for all of an HVAC system’s motors to start. In fact, they usually draw around three to five times as much power when starting up compared to how much they draw when fully running. When any of these motors start to fail, they often have issues where they can’t start up easily. This can sometimes lead to the motor drawing much more power than it should in an effort to start, causing the breaker to trip.

Unit Vibrates, Hums or Buzzes When It Turns On

If you hear your outdoor HVAC unit vibrating excessively or making a loud humming or buzzing sound when it starts up, it’s almost always a sign the compressor is failing. These sounds result from the compressor motor making a “hard start.” A hard start means that the compressor motor is struggling to turn on, which often causes it to vibrate and hum or buzz.

There may also be times when you hear a humming or buzzing sound when the unit tries to start but fails to turn on. In this case, it usually means that the unit’s start capacitor is bad. A start capacitor is essentially like a large battery that releases a powerful jolt of electricity to help the compressor motor and condenser fan motor start up more easily. Without this extra power, the motors often won’t be able to start up on their own. They can also end up overheating when they try to start and potentially burn out. In this situation, shut your HVAC system off immediately.

Unit Is Ticking, Rumbling or Rattling

A ticking noise when the unit turns on and off also usually indicates that the compressor is failing and having issues turning on and off smoothly. Rumbling and rattling noises instead typically indicate that the mounts that hold the compressor motor in place have come loose. This results in the motor shaking and moving around inside the sealed compressor.

Warm Air Blowing Out of Your Vents

Another potential sign that your compressor is failing is if your HVAC system is blowing warm air when in cooling mode. The same is true if your heat pump system starts blowing cold air when running in heating mode. The reason these issues can happen is that a failing compressor often can’t pump the refrigerant through the system as it should. A refrigerant leak or a frozen evaporator coil can also cause the system to blow warm air, which is why you’ll need a technician to diagnose the specific issue.

Moisture Puddling Around the Unit

Condensation can sometimes form within an outdoor HVAC unit and cause water to puddle up underneath and around it. Moisture can also be a sign that refrigerant is leaking out of the compressor, the condenser coil or one of the copper lines. These latter issues are quite serious and something that requires immediate attention from a professional.

Options for Dealing With a Bad Compressor

When dealing with a bad compressor, you have one of two options: replace the compressor or replace the entire unit. Compressors are fully sealed, which means there is no way for a technician to repair them. Unfortunately, replacing a compressor is extremely expensive and time-consuming and will usually cost well in excess of $1,000. This is why most people just opt to install a new AC or heat pump when dealing with a bad compressor. Nonetheless, it can be worth it just to replace the compressor if the unit is fairly new. It’s also usually worth it if the unit is under warranty and the compressor failed because it was defective. In this case, the manufacturer will provide a free replacement compressor, and you’ll only need to pay the labor fees for installing it.

What’s Considered an HVAC Emergency?

Written by Kevin on October 7, 2024. Posted in HVAC.

The HVAC system in your Sterling, VA, home is designed to provide you with comfortable and conditioned air throughout the four seasons. Unfortunately, occasional issues can interrupt the function of this system. How do you know when you’re experiencing an HVAC emergency? Let’s discuss the situations that warrant an emergency call to our team of HVAC technicians.

HVAC Emergency Basics

You’re experiencing an HVAC emergency if a situation in your home warrants immediate attention from an experienced professional. There may be an interruption in the function of your equipment, but it also may pose a danger to your safety or comfort. These emergencies can occur at any time. They can occur because of normal wear and tear of your equipment, a malfunction of your system, or a defect in your heating or cooling equipment or related components.

What Is Considered an HVAC Emergency?

There are several indications that you’re experiencing an HVAC emergency. They include the following.

Lack of Warm or Cool Air

If your furnace is no longer producing warm air or your air conditioning system isn’t cooling your home, this is an HVAC emergency, especially in the middle of extremely cold or hot weather. It’s important for your safety that you can maintain a safe temperature inside your home. Extremely cold or hot temperatures in your home can put your health at risk.

Not maintaining a safe indoor temperature can also impact your home’s structure, plumbing, and electrical systems. Cold interior temperatures can cause pipes to freeze and burst, causing extensive damage. This situation can even result in mold growth.

Odd Noises

While your HVAC system may still run normally and produce conditioned air, odd sounds should have been looked at immediately. Grinding, banging, or squeaking sounds indicate an interior component issue. If you ignore the problem, you could experience a system shutdown soon.

Bad Smells

The only smell you should ever notice from your heating or cooling equipment is a slightly dusty, stale odor when you change from heating to cooling or cooling to heating. This smell usually only lasts a few minutes, but if it doesn’t go away, there is a problem. If you notice the smell of gas or a burning smell, turn off your system and call a professional immediately.

Decreased Airflow

Your home may feel comfortable, but have you noticed less air flowing out of your vents? Your heating and cooling equipment may be keeping up with your set temperature, but it may be running more to do so. You may not realize the increase in runtime, though it’s likely raising your energy bill each month.

The first place to check is your air filter(s) to see if it needs to be changed. However, another common reason is that cracks or gaps in your ductwork have allowed conditioned air to escape. A damaged ductwork system isn’t an emergency but a service you can schedule. Another possibility is an interior issue with your blower motor. It is an emergency, and we can repair or replace it.

Hot or Cold Spots

Your airflow may remain the same, but some rooms of your home might feel hotter or colder than others. There’s a reason that your heating and cooling equipment is not providing consistent temperatures. This may be an emergency. However, non-emergency issues, like inadequate ductwork design or a dirty air filter, may also be causing the problem.

Water Pooling or Leaking

Do you have water pooling near the base of your HVAC system? You may have a clogged condensate drain. Condensation is a normal process of cooling your home, but this moisture is efficiently removed. Ignoring this water issue can lead to a damaged HVAC system, mold growth, electrical damage, and more.

Steps To Take During an HVAC Emergency

The following steps should be followed when you experience any signs of an HVAC emergency.

Switch off Your System

Regardless of the potential problem, you should turn off your HVAC system when you first notice something is wrong. This will prevent further damage and emergencies like fires or carbon monoxide leaks.

Contact a Professional for Assistance

Once your system is turned off, contact our team to schedule an emergency appointment. We will get to your home as quickly as possible, diagnose the issue, and come up with a fix. When you work with an experienced and knowledgeable team like ours, you can rest assured that your HVAC system will be back up and running.

Take Safety Precautions

This can mean several things during an HVAC emergency. If you suspect a gas or carbon monoxide leak, immediately open a few windows and leave your home. Don’t attempt to go back inside until a professional tells you that it’s safe to do so. You should never try to fix the problem yourself.

Retain Documentation of the Event

Depending on the scenario, you may want to retain documentation that states what happened and what needed to be fixed. If your homeowner’s insurance will cover the cost of the repairs, you’ll need to provide proof.

False Alarms

A few situations can impede the normal function of your HVAC system. However, these situations may not actually be emergencies.

Thermostat Issues

Check your thermostat to see if your system is on and programmed to perform the appropriate function. For example, if your thermostat is set to fan only, your heating and cooling equipment will not turn on.

Check Your Filter

Check to see if your air filter needs to be changed. A clogged and dirty air filter can impede airflow, decreasing airflow throughout your home.

Minor Repair Needs

If lucky, your HVAC issue may be repaired quickly by replacing a small part. With so many different components, one slight issue can affect your entire system. We don’t recommend homeowners check for cracks or gaps in ductwork because some attics can be dangerous if you don’t know where to step. That is a job for one of our HVAC technicians.

Routine maintenance is a great way to spot problems before they become an emergency. We recommend that you schedule this service annually before the start of using your furnace or air conditioner for the first time that year. Routine maintenance includes inspecting, cleaning, and maintaining various interior components in your heating and cooling equipment.

We also check your refrigerant levels, which can impact the efficiency of your air conditioning system.

Could a Smart Thermostat Help Me Reduce My Carbon Footprint?

Written by Kevin on September 10, 2024. Posted in HVAC.

If you are looking for ways to help reduce your carbon footprint, a smart thermostat might be the perfect answer. This unique type of thermostat does much more than just communicate with your HVAC system and tell it when to turn on and off. It provides a wealth of information about your energy consumption so that you can adjust your daily habits while also including some built-in features that make it possible to reduce your energy usage without lifting a finger. The following are a few ways a smart thermostat will help you reduce your impact on the Earth’s climate.

Learning Your Heating and Cooling Habits

Smart thermostats can learn your daily heating and cooling habits so that they can automatically adjust the settings on your behalf. If you continually turn the temperature up right before you leave for work every day, the thermostat will notice this happens on a regular basis and automatically make the adjustment for you. This will help you reduce your carbon footprint by making it less likely that you fail to adjust your temperature settings before leaving for an extended period so that your HVAC is not needlessly heating or cooling your home.

Remote Access

With a smart thermostat, you can connect to your system even if you aren’t at home, provided you have a smartphone. This smartphone app is another useful feature if you want to adjust the temperature settings when you are not around, so that you can avoid unnecessarily using your furnace or air conditioner. This is an especially useful feature if you are a forgetful person and often find yourself rushing out the door and forgetting to adjust your thermostat on the way out.

Detailed Energy Reports

Smart thermostats offer much better insights into your energy usage. Rather than having to log into your energy provider’s website and look at your usage, a smart thermostat will provide you with your own detailed usage report. These reports show you how much energy your system uses and when you use it the most. These insights can help you identify patterns in your energy consumption and spark ideas on how you can change your usage and habits. The report may even suggest certain changes you can make or specific maintenance that can be performed to help improve the efficiency of your HVAC system. Some smart thermostat models also provide you with cost analysis reports and comparative data with similar-sized homes and national averages. These figures can help motivate you to change your habits to meet specific energy consumption goals.

Geofencing Technology

If you are looking for a thermostat that allows you to make a setting and then forget about its use, a smart thermostat can help you reduce your carbon footprint thanks to geofencing technology. This type of smart thermostat uses geolocation data to detect when you are not at home, and the system can adjust your temperature settings to reduce energy consumption. When using this feature, you do not have to set any special programs or remember to change a setting before you leave. You can simply go about your day and rest easy knowing that your smart thermostat is doing the heavy lifting and reducing your carbon footprint.

Automatic Seasonal Adjustments

The changing of the seasons requires a change in your energy usage habits. How you go about making these adjustments to your HVAC system can have an impact on the efficiency of your system. As the months on the calendar change, your smart thermostat will know to start adjusting the temperature settings slowly on your behalf. If it is getting colder outside, your thermostat will start gradually increasing the temperature before you get home so that you arrive at a comfortable home. This will use less energy overall than if you came home and made a big adjustment to the temperature setting to heat your home.

Smart thermostats are often connected to weather forecasts and can adjust settings on upcoming weather conditions. This allows your thermostat to act in a similar fashion and get ahead of the extreme temperature shift by slowly increasing or decreasing the temperature in anticipation. This enables your HVAC system to run more efficiently, resulting in less of an impact on the environment.

Integration with Other Smart Devices

Smart thermostats are the perfect companion to other smart devices and help form an energy-efficient home. When you combine a smart thermostat with other connected devices, such as smart lights, the thermostat can use the signal of the light turning off to realize a room is no longer occupied. The thermostat can then adjust the temperature in that room knowing that no one is in it to preserve energy.

Similarly, a smart thermostat can work together with smart blinds or shades to help you scale back on your energy usage. In the summer, the thermostat can be connected to your smart blinds and shut them to block out the sun during the hottest part of the day. This will help keep your home cooler by reducing solar heat gain and limiting the energy needed to regulate the temperature inside your house. Conversely, in the winter, your thermostat can signal to open your blinds and let more heat into your home, reducing the need for your furnace to run as much as it otherwise would have.

Temperature Zoning

Temperature zoning is another great way a new smart thermostat can help limit your energy usage. This specific feature enables you to target certain areas in your home with specified temperatures. You can independently heat your master bedroom to one temperature while keeping your living room at a different one. This customized comfort setting is perfect if you find yourself spending most of your time in specific rooms. You do not need to worry about wasting energy heating or cooling your entire home to the same temperature but rather just the rooms that you spend time in.

Integration with Renewable Energy Sources

Smart thermostats also integrate nicely with renewable energy sources such as solar panels. If your solar system generates excess energy during sunny days in Sterling, VA, a smart thermostat can tap into this energy surplus to power your HVAC system. This feature, combined with the other energy saving features of a smart thermostat, helps manage the use of stored energy better, especially during peak demand times. If you are considering turning to renewable energy sources to power your home’s HVAC system, you should also install one of these thermostats to help you make the greatest impact for your efforts.

What Is a Dual Fuel System?

Written by Kevin on July 23, 2024. Posted in HVAC.

If you have an old furnace in your home that you need to replace, you should always make sure to take some time to think carefully about your options. Simply installing a new furnace isn’t a bad choice, but upgrading to a dual-fuel HVAC system can potentially be a much better option. This article will explain why that is and discuss everything you need to know about dual-fuel HVAC systems and how they work.

What Is a Dual-Fuel HVAC System?

The most common type of central HVAC system consists of an air conditioner and a furnace. There are also heat pump systems, which are different because the heat pump provides both air conditioning and heating. A dual-fuel HVAC system consists of a gas furnace and an electric heat pump. While it may seem pointless to have both a furnace and heat pump, this type of system actually provides major benefits in terms of both comfort and energy efficiency.

How a Dual-Fuel HVAC System Works

Heat pumps are incredibly efficient and typically use around half as much energy as any other heating unit. The reason we say they typically do is that heat pumps don’t put out nearly as much heat as a gas furnace does. A gas furnace heats the air flowing through it to around 140 degrees Fahrenheit, which allows it to quickly raise the temperature inside the house. Heat pumps typically only heat the air to somewhere around 90 to 100 degrees, which means they take longer to raise the temperature in the home by 1 degree. A heat pump will usually put out plenty of heat to maintain the temperature and keep the home warm, but it will usually need to run for an hour or more if it needs to raise the temperature by 5 degrees or higher. The temperature of the air a heat pump puts out also decreases a bit when it’s much colder outside.

The energy efficiency of a heat pump also continually decreases as the outdoor temperature drops. Some units can continue putting out at least some heat in temperatures as low as -15 to -20 degrees. Nonetheless, a heat pump will always work much more efficiently and heat more effectively when the outdoor temperature is above freezing.

A dual-fuel HVAC system overcomes all these issues since the furnace will always switch on when needed to provide additional heating and raise the temperature much faster. If you have a heat pump alone, you usually won’t want to turn your thermostat temperature down when you leave for work. If you did, the heat pump would need to run for an unnecessarily long time once you turned the temperature back up. This would usually then lead to the heat pump using more energy overall per day than it would if you just left the thermostat at the same temperature all day and night. This isn’t an issue with a dual-fuel system since the furnace will immediately kick on as soon as you turn the heat up again. That way the temperature will quickly increase to where it should be. Once the right temperature is reached, the furnace will shut off and the heat pump will then run a few times an hour to maintain the temperature in your home.

There may also occasionally be times throughout the winter when it’s too cold outside for the heat pump to work efficiently or even work at all. In these situations, the heat pump would just shut off and the furnace would run as needed until it warms up enough outside that the heat pump can again work effectively.

One other thing to understand about heat pumps is that they always slowly freeze up any time it’s 40 degrees or colder outside. This means they need to occasionally defrost, which they do by switching to cool mode so that hot refrigerant flows through the heat pump to melt the ice on its coil. That means instead of transferring heat from outside into the home, they start pulling heat out of the home just like they do when running in air conditioning mode. Even though the defrost cycle usually only takes 10 to 15 minutes, the house can get quite cold in that time since the heat pump is actively cooling instead of heating. This is another advantage of a dual-fuel system since the furnace will turn on when the heat pump is defrosting so that the home stays at the same temperature. The furnace will then shut off immediately when the defrost cycle finishes and the heat pump again switches back to heat mode.

Pros and Cons of Dual-Fuel HVAC Systems

The only real downside to a dual-fuel HVAC system is that it will cost you more than just a standard heat pump system. However, this isn’t as big of an issue as it may seem. That’s because a standard heat pump system always requires an auxiliary or backup heat source to work in a colder climate. Most systems have electric heat strips that are installed inside the home and will run in all the same situations as a furnace in a dual-fuel system. These heat strips have much higher energy requirements compared to a furnace. That means your heating costs will usually be higher with a standard heat pump system than they would be with a dual-fuel system in a colder climate.

Choosing a dual-fuel system is an excellent choice since it will ensure that your home is always sufficiently warm while using less energy than a furnace or heat pump alone. This makes installing this type of system a great alternative to a furnace and air conditioner. With such a system, the heat pump will effectively cool your home all summer and allow you to heat your home for less in winter.

The only time that it may not make much sense to invest in a dual-fuel system is if you just need to replace your furnace and you have an air conditioner that’s still relatively new and works well. In this case, you’re sometimes better to just replace your furnace now and then install a heat pump whenever it comes time to replace your air conditioner. Installing a heat pump alongside your new furnace will still save you quite a bit of money on your heating bills.
