A good gas furnace lasts, on average, 15 to 20 years. However, if you don’t care for it and give it the attention it needs, it can give out before its time. Here are five ways to help extend your furnace’s lifespan.
- Size it properly. A furnace that’s too small for your home has to work much harder to keep your house warm. A furnace that’s too big cycles on and off too quickly. Both wear out the system far sooner than normal, decreasing its lifespan significantly. Make sure your HVAC contractor gets you the correct-size furnace for your home.
- Change the filter. When the filter is clogged, airflow is restricted, and your furnace has to work harder to warm your home. By changing the filter regularly, you maintain a healthy airflow, saving energy and keeping your system from overworking, thus allowing it to last longer.
- Get a smart thermostat. A smart thermostat lets you set the temperature a little lower when you’re not home. Not only does this save energy by saving you from heating an empty house, it also helps your furnace last longer. By giving it time to rest rather than having it run constantly, you prevent your furnace from wearing out too quickly.
- Annual maintenance. Every fall, call your HVAC technician to check the system and make sure it’s in good working order. They’ll tighten the screws, oil the machinery, replace any parts that are about to give out, and keep it running efficiently. Doing this annually will help your furnace last much longer.
- Repair vs. replace. No matter how well you care for your furnace, it’s going to break down occasionally. If you follow the guidelines above, though, there’s a good chance that it’ll be as good as new after a few repairs. Don’t replace it unless you have to. A good HVAC technician can often get it up and running again and keep it that way for years to come.
