Gas Furnace Maintenance

Ensure the longevity and peak performance of your gas furnace with routine maintenance from Ranger HVAC, keeping you cozy and worry-free.

Essential Gas Furnace Maintenance Tips

As temperatures drop, it’s important to ensure your gas furnace is in top working condition. Regular furnace maintenance helps prevent breakdowns and ensures your furnace runs efficiently, saving you money on energy bills. This guide covers essential gas furnace maintenance tips to keep your home warm and cozy all winter long.

Why Gas Furnace Maintenance is Important

Regular maintenance is crucial for the longevity and efficiency of your gas furnace. Here’s why:

Prevent Costly Breakdowns: A well-maintained gas furnace is less likely to break down, saving you from expensive furnace repairs or a furnace replacement. Regular inspections and cleanings can catch potential issues before they become major problems.

Ensure Efficient Heating: A dirty or malfunctioning furnace can lead to uneven heating or cold spots in your home. Regular maintenance helps ensure your furnace runs at peak efficiency, providing consistent and comfortable heat.

Save Money on Energy Bills: A well-maintained furnace uses less energy to heat your home, resulting in lower energy bills. Keeping your furnace in top condition can significantly reduce heating costs during the winter.

Gas Furnace Maintenance Checklist

Here are essential gas furnace maintenance tips to keep your furnace running smoothly:

Inspect the Furnace: Look for signs of wear and tear, such as rust, cracks, or loose connections. Check the air filter and replace it if it’s dirty or clogged. A dirty air filter restricts airflow and strains your furnace.

Clean the Furnace: Dirt, dust, and debris can build up inside your furnace, affecting its performance and efficiency. Use a vacuum with a brush attachment to clean the exterior and interior. Ensure the blower, motor, and fan blades are thoroughly cleaned.

Check the Thermostat: Make sure your thermostat is working properly and set to the correct temperature. If you have a programmable thermostat, check the settings and adjust them if necessary. A properly functioning thermostat is essential for efficient heating.

Inspect the Flue Pipe: The flue pipe removes exhaust gases from your furnace. Check it for signs of damage or blockages. If you notice any issues, contact a professional for repair or replacement.

Lubricate Moving Parts: Your furnace has many moving parts that require lubrication. Check the owner’s manual for instructions on which parts need lubrication and use a high-quality lubricant.

Check the Gas Connections: Inspect gas connections for leaks or damage. If you notice a gas smell or hear a hissing sound, turn off the gas supply and contact a professional immediately.

Test the Ignition System: The ignition system lights the gas in your furnace. Test it to ensure it’s working properly. Check and clean the flame sensor. If you have an older furnace with a pilot light, ensure it’s lit and burning a steady blue flame.

Clean the Vents and Ducts: Dust, dirt, and debris can build up in your vents and ducts, affecting furnace efficiency. Use a vacuum with a long hose attachment to clean them. If there are blockages, contact a professional for cleaning.

Schedule a Professional Inspection: While you can do much of the maintenance yourself, schedule a professional inspection at least once a year. A technician can thoroughly inspect your furnace, identify potential issues, and perform necessary repairs or maintenance.

Signs Your Gas Furnace Needs Maintenance

Here are signs your gas furnace may need maintenance:

Strange Noises: Unusual noises such as banging, rattling, or squeaking can indicate a problem. Contact a professional to inspect and repair your furnace.

Uneven Heating: If some rooms are warmer than others, your furnace might need maintenance. Uneven heating can be caused by a dirty air filter, blocked vents, or a malfunctioning furnace.

High Energy Bills: Higher-than-usual energy bills may mean your furnace isn’t running efficiently. A dirty or malfunctioning furnace uses more energy to heat your home.

Frequent Cycling: If your furnace turns on and off frequently, it could be due to a dirty air filter or a malfunctioning thermostat. Contact a professional to inspect and repair your furnace.


Regular gas furnace maintenance is essential for efficiency and longevity. By following these maintenance tips, you can ensure your furnace runs smoothly and efficiently all winter long. Schedule a professional inspection annually to catch potential issues before they become major problems. Stay warm and cozy this winter with a well-maintained gas furnace. If you find your furnace frequently needing repairs or not heating effectively, consider a furnace replacement. Whether you have a gas furnace or are thinking about an electric furnace, proper furnace installation and regular maintenance are key to a warm, comfortable home.

Our experience with Ranger HVAC was great. Our ground level HVAC system crashed after 20 years in the middle of a heatwave, in 2022. We called and scheduled a appointment for an estimate on a new system, Mike came out and explained all our options and helped us to pick the best system for us and our home. He was very professional and thorough. The whole experience was great and we would recommend Ranger HVAC to our friends and family. The workers that came out and installed the system were extremely nice and cleaned up after they were finished and were very informative about the whole new world of smart HVAC systems. The office support kept us informed of all the visits and invoices were completed electronically. Update We were so satisfied with Ranger's customer service that, four months later, when our 2nd HVAC system in the attic crashed on the new year's eve, after 20 years, we called Mike to install a new one. We couldn't be more happy with the results. Jennifer and Rudy

My heating system stopped working and a good friend of mine advised to me reach out to Ranger HVAC. The company representative responded in a timely manner and the diagnostic indicated issue with my blower motor, which required replacement. Ranger HVAC team brought in a new motor and replaced it at precise scheduled time with no delay.

Ranger HVAC installed a new HVAC system at my house yesterday. The company did an excellent job communicating with me from the time I requested a free estimate to the morning they arrived on site. They were careful to cover all the traffic areas and wore shoe covers. A team of three, including Michael the leader, completed the install to my satisfaction. They were patient to answer all my questions. I selected Ranger HVAC based on their knowledge, fair price, and honesty. Michael, who gave me the estimate, spoke from experience, having been himself an HVAC technician. The company didn't try to sell me what I didn't need. I felt that the information I received could be trusted. And indeed they delivered as promised! I am very pleased with the install and I highly recommend this company. Thank you Ranger HVAC for a job well done!

I had my HVAC ducts cleaned by Ranger HVAC this past week and was so impressed by their work. I saw what a comprehensive process it is and I’m very pleased with the result. Staff always cover their feet when in your home and are very careful when removing and replacing the vent covers and moving their ladders and equipment around. Very fair price as well. Thanks to Sean, Kofi, and Paul for a thorough job well done. I have already recommended Ranger to a couple of friends and will be contacting Ranger for any future HVAC issues.

    Definitely a very good experience. If you're interested, the service is exactly what he says it is; he clearly explains everything he does and you can tell he's being sincere. He isn't pressuring you or trying to upsell you. Just an honest, high-caliber effort. Highly advised.

      He did a fantastic job cleaning and inspecting my commercial AC unit. He made suggestions that I was completely unaware of regarding how to improve circulation and air flow as well as how to minimise my use of electricity during the summer. Excellent rates and service. Once more, many thanks!

        He is the top in his field! Without having to be at 69 degrees, the AC functions better than before. Additionally, because the heater is so hot, we don't need to turn it up all the way, which saves us money.

        Andrea Magaña


          The crew was excellent, and I'm glad I found them since they are nice, down-to-earth people who didn't try to upsell me on items I didn't need instead of telling me about innovations that would make life better for my allergic relatives. All Degree Comfort comes highly recommended.
