Why Does My Furnace Keep Shutting Off?

There is usually a sense of anxiety when you realize something isn’t quite right with your furnace. You’re sitting at home and you hear your furnace is continuously kicking in and shutting off. However, before you panic, there are some things you can check when you first notice that your furnace seems to be shutting off more frequently 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 inside your home cleaner, but they also support keeping your system clean. Your first step when you recognize a concern 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 weeks ago and forgot about it, especially when using a smart or programmable thermostat. Examine your thermostat to see if anything unusual is taking place or if it could need new batteries. The site of your thermostat could make a difference, as well. If it’s located in a place that’s often hotter than the rest of your home, such as in direct sunlight or by another heat source, it could be mistakenly assuming your home has met 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 ensure they are all closed and take a look at the seals around your windows for any drafts or cold air entering the home.

While you can look at these issues yourself, if issues still persist after these checks, it might be time to call in the experts. When your furnace is consistently turning off, it can end up forcing unnecessary work and stress on your system that could cause more pricey repairs or even a replacement.
