How Often Do You Really Need Furnace Maintenance? Expert Insights for Homeowners

Written by Kevin on December 13, 2025. Posted in Furnace.

You may wonder how frequently you need to schedule furnace maintenance. It’s easy to overlook this task when your system seems to work well, but regular care delivers real benefits. A consistent maintenance schedule keeps your home comfortable, improves efficiency, and gives you a clearer picture of the system’s long-term health. When you understand how often to service your furnace and what happens during a visit, you can make better decisions when it comes to your heating system.

Why Regular Furnace Maintenance Matters

Furnace maintenance supports more than comfort. Homeowners who stick to a consistent schedule enjoy better energy efficiency, improved reliability, fewer breakdowns, and healthier indoor air. A furnace works hard throughout the winter, and its components face heat, stress, vibration, and continuous airflow. Dirt accumulates, and that buildup directly affects how well the system performs. When you treat maintenance as an annual chore, your system has the best chance to run smoothly during the coldest months.

Efficiency Improves When You Stay Consistent

Your furnace runs more efficiently when it stays clean and properly adjusted. Dust, debris, and worn parts force the system to work harder than necessary. Over time, that extra strain raises your utility bills and reduces overall performance. One of our technicians will reduce that burden by cleaning components, tightening connections, checking electrical parts, and ensuring the burners, heat exchanger, and blower work the way they should. Once everything functions smoothly, the furnace uses less energy to warm your home.

Reliability Increases When You Address Issues Early

Small furnace problems rarely remain small. Dirt on the flame sensor, a failing capacitor, or a loose wire can cause your entire system to shut down. When our technicians inspect your system every year, we identify these issues before they disrupt your heating. You gain peace of mind because the furnace will start, run, and heat your home reliably throughout winter.

The Ideal Furnace Service Frequency

Most homes need a single professional tune-up every year. This schedule fits both gas and electric furnaces because each system contains components that require cleaning, inspection, and calibration. A yearly visit gives your system the care it needs before the heating season begins.

Schedule Service Every Fall

The best time to schedule furnace maintenance is early fall. Outdoor temperatures remain mild, and you give the technician plenty of time to correct any emerging issues. When you take care of your system before winter arrives, you avoid the last-minute scramble and reduce the risk of mid-season breakdowns. Early fall service also improves comfort, because your furnace will run at peak performance from the first cold day of the season.

Older Systems Need Extra Attention

Newer furnaces handle an annual visit well, but older units often need more frequent monitoring. When your system reaches 12 to 15 years of age, components wear out more quickly. The furnace might still work, but it may show signs of strain. You can schedule a mid-season check if you notice unusual noises, longer run times, or cold spots throughout the home. Frequent care helps an aging furnace maintain safe and efficient operation until you decide to replace it.

Tasks to Perform Between Visits

You play a major role in furnace maintenance, even with a yearly professional tune-up. Your daily and monthly routines help the system work smoothly and reduce strain. Most tasks require no special tools and only take a few minutes to complete.

Change the Air Filter Regularly

Your furnace depends on steady airflow, and the filter plays the largest role in maintaining that flow. A clogged filter blocks movement and forces the blower to work harder. You can check the filter monthly and replace it whenever it looks dirty. Most homes need a new filter every one to three months. Once the blower receives enough fresh airflow, the furnace runs more efficiently and stays cleaner throughout the heating season.

Keep Vents and Registers Clear

Your vents must remain open and free from obstructions if you want consistent airflow. Furniture, rugs, and clutter often cover registers without you realizing it. When you walk through your home, confirm that each vent opens fully and releases warm air without interference. This simple step will help your furnace distribute heat evenly throughout your living space.

Watch for Unusual Signs

Your furnace communicates its condition through sounds, smells, and performance changes. When you hear rattling, screeching, or grinding, the system likely needs attention. If you notice new drafts or uneven temperatures, the system could be struggling to keep up. Unusual odors also indicate trouble, especially burning or chemical smells. When you stay alert to early warning signs, you give your technician valuable information and prevent worsening problems.

What Professionals Do During a Furnace Tune-Up

A professional furnace maintenance visit covers far more ground than simple tasks. Our technicians examine parts you can’t easily access, measure performance, and run safety tests.

Clean and Inspect Critical Components

We start by opening the furnace cabinet and cleaning buildup from the burners, blower assembly, and flame sensor. We will also check for cracks or corrosion inside the heat exchanger, because this component handles extreme temperature changes every time the furnace runs. A cracked heat exchanger creates a carbon monoxide hazard, so our technicians treat this inspection as a high priority. Once they confirm the heat exchanger’s condition, we move on to electrical parts, wiring, and controls.

Test Gas or Electrical Operation

Gas furnaces require careful testing of ignition, gas pressure, and combustion. Our team verifies proper flame height and color, checks for leaks, and makes sure that components ignite and shut off correctly. Electric furnaces need a different approach. We confirm the condition of heating elements, check for overheating, and verify proper amperage.

Verify Airflow and Temperature Output

Airflow plays a major role in comfort and efficiency. We measure temperature differences between the return and supply air and confirm that the blower motor delivers the right amount of airflow. If the blower struggles or fails to reach the correct speed, our technician investigates the motor, capacitor, and control board. Once the system meets performance expectations, the furnace can heat your home consistently.

The Long-Term Benefits of Staying on Schedule

A consistent maintenance routine supports your furnace’s lifespan. Systems that run clean and well-adjusted often last several years longer than neglected units. You also gain better heating performance throughout the winter, fewer surprise repairs, and more predictable energy costs. When you treat your furnace as a major home investment, routine professional care becomes an easy decision.

Regular Care Protects Your Budget

A well-maintained furnace rarely develops major problems without warning. When our team catches small issues early, you avoid expensive repairs and unexpected failures. That level of foresight helps you plan for future replacement and budget more comfortably.

Maintenance Improves Safety

Safety plays a central role in furnace care. Gas leaks, electrical issues, and heat exchanger problems create serious risks when left unchecked. A technician’s yearly visit ensures safe operation and gives you greater peace of mind as your system runs through the coldest nights of the year.

Reliable Heating Maintenance

You typically only need one professional furnace service each year, ideally in early fall. When you combine a yearly visit with basic at-home tasks like filter changes and vent checks, your system stays in strong condition. At Meades HVAC, we have been providing heating and cooling services in the Sterling area for years, building trust in the community. Contact us today to schedule heating maintenance.

Reasons Why Your HVAC Filter Turns Black

Written by Kevin on November 6, 2024. Posted in Furnace.

Many homeowners know that they need to change their HVAC filters regularly. When you swap the old filter for a new one, it will usually be clogged with grey particles. However, some situations may cause the filter to turn black. Should you be worried? In most cases, the answer is yes.

The filter is an essential part of your home comfort system. Heated air from the furnace circulates through it in the winter, while cooled air makes its way through the fibers in warm months. All year long, the filter traps a variety of particles, including allergens, dust, dirt and even viruses and bacteria. When the filter quickly turns black, it’s a sign that something is amiss in your environment. Here are some common reasons for a black furnace filter.

Soot

Soot occurs when combustion systems don’t burn properly. Over time, soot collects on surfaces like walls, carpets, curtains and your air filter. Removing soot from your home is critical because its presence can make you ill. Breathing in soot can lead to lung and respiratory diseases and even premature death. To remove soot from your home’s air, use a carbon-activated filter in your furnace to trap these particles. Air filters clogged with soot can also lead to mold and other allergens in your home. Here are some common causes of soot.

Scented Candles and Fireplaces

If you regularly burn scented candles, they can contribute to a black air filter. These candles don’t burn cleanly because they have a lot of unsaturated oils. If your candle flame is yellow or orange instead of blue, it’s producing a lot of soot. The most effective way to limit soot from candles is to stop burning them, but you can also limit wicks to one-quarter inch in length. Also, keep candles away from vents, fans and hallways.

If you use a fireplace during cold weather, ensure it is adequately vented. You can always expect some soot from an indoor fire, but how much enters your home depends on how you operate it. To minimize soot, keep glass doors and vents open during operation. Remove old, cracked and broken logs, and if you have a gas fireplace, have a professional occasionally inspect the burner and gas pressure.

Forest Fires

Although you can’t control this phenomenon, massive forest fires thousands of miles away can clog your air filter with black soot. If you have an air quality alert due to forest fire smoke that has drifted over Virginia, keep your doors and windows closed as much as possible until the air mass passes. Change the filter immediately afterward to help airflow.

Improperly Operating Gas Furnace

Problems with specific parts of a gas furnace can cause improper burning, leading to soot and a serious situation. Yellow or orange flames coming from the burner indicate improperly burning. Possible causes, including the following:

Cracked heat exchanger
Improper venting of combustion gases
Misaligned or clogged burners
Dirt or debris clogging gas valves

A furnace that’s improperly burning combustion bases needs prompt attention from an HVAC technician. This situation can lead to flame rollout, where furnace flames leave the unit in search of oxygen.

Improperly Burning Gas Appliances

An incorrect mixture of air and gas can cause this appliance to produce soot. As with other potential problems, check the heater’s burner for yellow flames instead of blue ones, which indicate proper combustion. Have a professional inspect the unit and remedy unsafe conditions like dirty burners, debris blocking the flue and lack of oxygen in the area surrounding the heater.

Black Mold

This organism thrives in moist environments, making furnace filters the perfect breeding grounds. This problem arises more commonly in the summer when you run the air conditioning side of the system. When you run the air conditioning, the evaporator coil becomes damp with condensation. Moisture that mixes with dust and dirt can lead to black mold growth, eventually spreading to the main unit and the filter. Mold growth can also occur in the ducts and other damp areas like basements.

Mold growth can be as dangerous as a gas or carbon monoxide leak. Various types of mold can grow in this environment, especially when the filter is clogged with other debris. Regular furnace maintenance and cleaning, as well as periodic duct cleaning, will keep mold out of your system and block excessive growth. Letting mold get an excessive hold in your home also has expensive consequences. Mold remediation costs many times more than regular HVAC maintenance.

Not all molds that are black in color are the toxic black mold species, Stachybotrys chartarum. Many other species of mold can be black in color and cause respiratory symptoms. This is especially true if you have allergies. If you see mold and are concerned about your health, you can find mold testing kits at most hardware stores. These kits allow you to collect pieces of this mold and send it to a lab for identification. The lab will then send a list of species and the level of health risk they present.

Carbon Monoxide

Carbon monoxide is a colorless, odorless gas, but when it is present in your home at high levels, it can turn your HVAC filter black. Gas-powered furnaces require fire to operate and produce carbon monoxide through the combustion process. High carbon monoxide levels can indicate a problem with your furnace. If you suspect carbon monoxide is the culprit, immediately order a carbon monoxide test to accurately determine whether you have dangerous levels inside your home. You can also purchase combination smoke and carbon monoxide detectors for your home.

When to Call an HVAC Technician

Regularly replacing the air filter inside your HVAC system can help avoid black filter situations. However, the older your furnace is, the more likely something will go wrong with the unit requiring professional repair. Change or wash your filter according to manufacturer recommendations. If you have an older HVAC unit and want to keep tabs on its operation, you can check the filter’s condition every 30 days. Filters are meant to improve indoor air quality, yet they also act as a sign that something may be amiss.

Benefits of Gas Furnaces

Written by Kevin on August 5, 2024. Posted in Furnace.

If you’re in the market for a new heating system for your home, then you have many options available to you. One of the more popular options these days is to go with a furnace. These are fairly inexpensive, energy-efficient, and available in models that burn different types of fuel.

What Is a Gas Furnace?

A gas furnace is a heating appliance that uses natural gas to generate warmth for your home. It uses a series of ductwork that is connected to all the rooms throughout your house to distribute heat and circulate air to ensure a stable indoor temperature. All gas furnaces are controlled with a thermostat.

How Does a Gas Furnace Work?

Newer gas furnaces use an electric igniter that produces a spark to ignite the natural gas as it goes into the burner assembly. This mixture of air and fuel will create combustion that produces heat. The heat is transported into metal chambers inside your furnace, where it eventually comes into contact with your blower fan. This heat will transfer to the air inside your ductwork, and your blower fan will work to deliver that hot air to the different rooms throughout your home.

No On-Site Storage Required

When it comes to other types of fuel-burning furnaces, like those that utilize heating oil and propane, you must have a storage tank on-site. Typically housed either in the basement or outside your home, these tanks can take up a lot of space and aren’t very aesthetically pleasing.

When you opt to go with a natural gas-burning furnace, it will be powered by natural gas that is directly piped into your home. This eliminates the need for having any on-site storage. It also helps to ensure that you have a consistent supply of fuel and never have to wait for delivery. This can give you peace of mind about your wintertime heating needs.

Cheaper Operating Costs

Another advantage of investing in a gas furnace is that it’s much cheaper to run than other options. Natural gas is cheaper to purchase than heating oil or propane. Furthermore, it’s significantly more affordable than paying for electricity to run an electric furnace. With cheaper operating costs, you can enjoy spending less money for your utility bills during the winter months.

Mostly Clean-Burning

As with any sort of fuel-burning furnace, there will always going be some exhaust fumes emitted. However, natural gas is known to be one of the cleaner burning fuels. It produces mostly water vapor mixed with a small amount of carbon dioxide. By burning natural gas, you can leave behind a smaller carbon footprint than you would with other types of fuels.

Quick Heating

One lesser-known advantage of investing in a gas furnace is that it can provide your home with more comfort. Whenever your furnace kicks on, natural gas will burn at a higher temperature than other types of fuel. This will help to produce more heat for your home in a timelier fashion.

Readily Available

Natural gas is now readily available across most of the country. With more and more rural communities getting access to it each year, natural gas is going to be around to stay for quite a while. You can have peace of mind knowing that your gas furnace won’t be obsolete any time soon.

Works With Existing Ductwork

Gas furnaces are designed to operate as forced-air systems, meaning one in which a blower fan circulates air throughout the ductwork. If your home already has existing ductwork for your old heating or existing air conditioning system, then it’s quite simple to have a new gas furnace installed. In fact, many HVAC companies offer convenient oil-to-gas conversions so you can switch from a costly heating oil furnace to a more energy-efficient natural gas furnace.

Less Expensive Than Heat Pumps

When homeowners are looking for energy-efficient heating systems, their options are essentially narrowed down to furnaces and heat pumps. When comparing the up-front investment into these systems, it immediately becomes clear that the price of a furnace is around half of what a new air-source heat pump system would cost. This lower initial expenditure makes them much more affordable for the average homeowner.

Effective in All Types of Climates

When comparing new heating systems, it’s important to take your specific climate into consideration. While heat pumps can be efficient, they only operate with peak efficiency in mild climates. However, the tried-and-true gas furnace has been shown time and time again to be effective at heating homes in all different types of climates. It’s truly a universal heating system that all can enjoy.

Tax Rebates

These days, gas furnaces are available in high-efficiency models. While they do cost more up-front, they can more than pay for that extra initial expense in energy savings over the years. The beauty of investing in one of these high-efficiency gas furnaces is that it makes you eligible for some tax incentives. Thanks to the federal government’s Inflation Reduction Act, homeowners can get back up to $600 of the purchase of their new furnaces in the form of tax rebates. Only select high-efficiency gas furnaces are eligible for this offer. Furthermore, many local municipalities and state governments are also offering tax incentives for homeowners who purchase these high-efficiency models. This is all in an effort to encourage homeowners to reduce their energy usage.

Greater Longevity

A typical furnace that burns natural gas will have an expected life span of around 15 to 30 years, assuming it gets proper maintenance and upkeep. On the other hand, an oil-burning furnace will only have an expected life span of around 15 to 20 years. This longer lifespan is because natural gas burns much cleaner and won’t cause an excessive buildup of dirt, grime, and other debris on the furnace’s internal components.

Enhanced Home Value

Modern homeowners are becoming more concerned with the specific types of heating systems they have. Homebuyers want to invest in a system that is eco-friendly and relatively inexpensive to operate. A natural gas furnace is one of the best options to fit this bill. Therefore, it will go a long way in helping to increase your home’s overall resale value.

Ease of Maintenance

A gas furnace is a fairly simple heating system that’s very easy to maintain. As a homeowner, you’ll need to replace the air filter about every two to three months. The frequency for changing filters will vary from one household to the next. It depends on numerous factors, like how many pets you have and whether you smoke. You’ll also need to schedule professional maintenance service once a year during the fall. This service will take care of cleaning and inspecting the system’s internal components.

What Is the Weird Noise Happening in Your Furnace?

Written by Kevin on November 21, 2023. Posted in Furnace.

When you are a homeowner in Virginia, it is likely that you are going to need to run your furnace all through the colder months to keep your indoor temperature comfortable. That is why hearing your furnace make a strange sound is so alarming. What does the sound mean? Is it a problem that is going to cause your heating system to break down in the middle of the winter? Having these kinds of concerns is understandable, but not all sounds need to be a cause for major concern. Educating yourself on the types of sounds your furnace can make is very helpful in knowing what sounds are likely not too big of an issue and which ones should have you calling in a local HVAC professional immediately.

What Is the Scraping Noise You Are Hearing?

If you are hearing a scraping noise, there could be an issue with your blower wheel. The metal-on-metal scraping sound can be from the blower wheel becoming loose and coming into contact with the blower casing. There is also the possibility that the blower wheel is completely broken.

Should you encounter this type of sound, it is important that you turn off your system immediately and get in contact with a technician.

What Is the Screeching or Squealing Sound?

When there is a screeching or squealing sound, this generally points to a problem with the blower motor. In some cases, however, the sound you are hearing could be due to a broken belt. Turn off your system and contact an HVAC professional. If it turns out to be the blower motor, it may just be a matter of lubricating motor bearings that have dried out. If the sound winds up being from a broken belt, then the technician will install a belt replacement.

What Does It Mean if You Hear Popping or Banging?

When you hear popping or banging noises in your furnace, this is not immediately cause for concern. This sound can simply be from your ducts expanding and contracting. If these sounds get exceptionally frequent and loud, this could mean an actual problem. An issue with the ductwork could lead to loud popping or banging sounds. Another possibility is the burners becoming dirty, which can result in a delay in ignition. This could end up cracking the heat exchanger, which would be a costly repair. More important than that, a cracked heat exchanger could threaten the safety of you and your loved ones.

What Is a Whistling Sound in Your Furnace?

A whistling sound in your furnace is usually your blower motor, much like when you hear squealing or screeching. This is typically due to airflow issues, which could be remedied by opening all of the vents or changing the air filter. The whistling sound is likely stemming from the blower straining to draw in enough air for heating. A sound like this is not a major concern, but it should still be run past your HVAC technician.

When There Is a Rattling Sound

A rattling sound usually stems from there being a loose door or panel. This could be as simple of a fix as tightening any loose screws to ensure that all of the panels and doors that are outside of the furnace are fixed firmly. If this does not resolve the issue, then the rattling could be from a loose part that can be found by an HVAC technician.

There are rare occasions when rattling can be caused by a crack in the heat exchanger. If this is the case, dangerous amounts of carbon monoxide could be leaking into your home. If the problem is not a loose door or panel, turn off your system immediately to have a professional come out to check for loose parts or a cracked heat exchanger.

When You Hear Rumbling

There may be a slight whoosh or roar when your furnace completes a heating cycle. If you instead hear a rumbling sound, this could be a problem. A loud rumble could be from there being an issue with the burner. This typically comes from fuel continuing to burn in the combustion chamber after the burners are off. When you hear a loud rumbling, keep your system off and call a professional immediately.

What Does a Humming or Buzzing Sound Mean?

It is typical of most furnaces to emit a low-level humming or buzzing sound while in operation. If the sound is loud, however, there could be a problem with either the fan or the motor. You should have a technician look at your system right away.

What Does a Thwapping Sound Mean?

Thwapping is a sound much like a card in the spokes of a bicycle tire. This is usually caused by something interfering with the blower blades. An issue like this is not of immediate concern but should be inspected by a professional. A belt or motor can wear out more quickly if the problem is left unfixed. It could also lead to a decrease in efficiency and eventually a costly repair.

What the Clicking Sound You Hear Is

You may hear a clicking sound when you start up your furnace, which is the sound of the ignition system lighting the furnace. There is only a problem with this sound if you continue to hear it repeatedly throughout the heating cycle. You may also hear a repeated clicking sound while your furnace fails to ignite altogether. This can be due to dirty burners, damaged flame sensors, or a defective valve or ignition board.

Other possible reasons for the clicking sound are an issue with the control panel, fan motor, or compressor. Repeated clicking sounds should not be ignored and merit a swift call to a qualified HVAC technician.

Normal Sounds for a Furnace

Now that you know the sounds that indicate a problem, it is also important to be aware of the sounds that are part of normal operation.

Chirping Sounds

Chirping is typically just a natural noise that comes from the system’s mechanisms.

Short-Term Rattling Sounds

When there is short-term rattling as the system cools after a cooling cycle, this is not a cause for alarm.

Crackling Sounds

When metal components cool after the end of a heating cycle, this is a normal part of operation.

Pinging Sounds

This type of sound is also a normal occurrence when metal contracts within the duct system.

Speak to a Professional About the Weird Sounds You Are Hearing

If you are hearing unusual sounds, it is always worth erring on the side of caution and speaking to a professional about it. At Meades HVAC, we understand the importance of knowing that your furnace is working at its full potential and that you can continue to count on it for years to come.

Restart Your Pilot Light in 3 Easy Steps

Written by Kevin on September 22, 2023. Posted in Furnace.

Pilot lights go out from time to time, and it generally isn’t a cause for major concern. It is, however, important to have a professional take a look at your furnace to figure out what is causing it to extinguish and relight it for you. Should your pilot light continuously go out or simply not relight at all, that could be an indication something is potentially wrong.

Instructions for relighting your pilot light are typically on the access panel of your unit, and it is a fairly simple process. You will be working with gas, however, so it is best to leave this type of work to a professional. Once a trained professional has walked you through the process and made sure there is no sign of a bigger problem, you can consult with them about reigniting the pilot light on your own in the future.

What Is a Pilot Light?

If you have an older furnace, it is typically equipped with what’s known as a pilot light. This is a small flame that generally runs blue, utilized for igniting the natural gas that is going into your unit’s main burner. With your furnace engaged to heat your home, gas releases through a valve, providing heat when ignited by coming into contact with the pilot light.

The pilot light utilizes natural gas, which comes in a small tube. There is a safety mechanism, called a thermocouple, that prohibits the flow of gas if it’s detected that the pilot light has gone out.

Reasons a Pilot Light Would Go Out

There are several reasons a pilot light could go out. Some of the reasons are minor and dealt with easily, while others take more involvement. It is important that a professional has a look at your furnace to determine what the reason actually is.

Reasons why a pilot light could go out include:

Air flow issues
Gas is shut off
Furnace needs cleaning
Issue with the thermocouple

Airflow issues can be attributable to things like a gust of wind or a leaking furnace duct. Another potential cause is a chimney or flue that is incorrectly sized, damaged, or not installed properly. All of these possibilities could be responsible for blowing out your pilot light. A professional can assess if any of these airflow issues are causing your pilot light to go out.

Shut-off gas can also be a reason why your pilot light has gone out since your pilot light is reliant on natural gas to stay lit.

If the opening in the gas pipe that fuels your pilot light has gotten dirty, this can have an effect on how well your pilot light is working. It might not be receiving enough fuel to stay lit. A good indicator of this is the color of the flame. If it is burning blue, then it is receiving the proper amount of fuel. When the flame is burning yellow or red, this means your pilot light is not getting enough gas. Regular cleaning of your furnace by a professional can minimize the chances of this happening.

A pilot light going out can also be due to a thermocouple issue. This can happen when your thermocouple is faulty or loose. If this is the case, your thermocouple will need replacement or adjusting.

Steps for Restarting Your Pilot Light

1. Turn Off Your Furnace

It is imperative that the first step taken is to shut off your furnace completely before making an attempt to reignite your pilot light. Failing to turn the furnace off first could potentially lead to home damage or even bodily harm. Even after your furnace has been completely shut off, a good rule of thumb to follow for safety is to wait five minutes before attempting to reignite the pilot.

2. Locate the Relevant Mechanisms

After your furnace is off, you will want to locate both your gas valve and your pilot light button. These are both generally located towards the bottom of your furnace. At this point, you will want to make sure you set the gas valve to the “Pilot” position and that you are in a comfortable spot to be able to press the red pilot light button.

3. Reignite the Pilot Light

Whether your pilot light is manual or automatic will determine how you light it. An automatic pilot light requires that you simply press the red button, while a manual one necessitates that you use an external source of flame. Manual pilot lights often require that you open a panel to access them. If you have a manual pilot light, you will want a long-handled match or lighter. You will be familiar with these as the kind you use when you light up the family barbeque. If your pilot light is manual and you do not have this type of match or lighter, you can use pliers to hold a lit wooden match, being sure to stay a safe distance from the flame.

For a manual pilot light, you will now light the orifice while pressing the red button. Once ignited, take your flame source away from the orifice while keeping the button pressed down for about a minute. After a minute has passed, let go of the button, and it should remain lit.

Finally, turn the gas valve to the “On” position and turn your furnace back on. If you had to get to your pilot light by opening a panel, be sure to close it.

Remember, while reigniting a pilot light can be a simple process, you are dealing with dangerous gas. It is always best to deal with a trained professional when servicing your home furnace.
