Why Does My Furnace Keep Shutting Off?

There is always a sense of dread when you notice something isn’t quite right with your furnace. You’re relaxing at home and you hear your furnace is endlessly kicking in and shutting off. However, before you panic, there are a few things you can check when you realize your furnace seems to be shutting off more than usual than it should be.

  1. Check the air filter in your furnace—You may think that air filters are only used to help keep the air in your house cleaner, but the filters also work to keep your system clean. Your first step when you notice a problem with your system should be taking a look at your air filter to see if it needs to be replaced. If it’s clogged or dirty, it can make it difficult for air to flow over the heat exchanger.
  2. Look at your thermostat—For lots of us, we may have set our thermostats several months ago and forgot about it, even more so when using a smart or programmable thermostat. Examine your thermostat to see if anything unfamiliar is occurring or if it might need new batteries. The location of your thermostat could make a difference, as well. If it’s located in a place that’s usually hotter than the rest of your space, such as in direct sunlight or close to another heat source, it could be mistakenly assuming your home is already up to the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have the right insulation, your furnace is likely to shut off more often. Walk around your home and check the windows to make sure they are all closed and inspect the seals around your windows for any drafts or cold air entering the home.

While you can certainly check for some of these issues yourself, if issues still continue after these checks, it might be time to call in the professionals. When your furnace is always turning off, it can result in unnecessary work and stress on your system that could lead to more costly repairs or even a replacement.
