Why Does My Furnace Keep Shutting Off?

There is typically 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 a few things you can check when you first notice that 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 they also support keeping your system clean. Your first step when you realize there is a problem with your system should be examining your air filter to see if it needs to be replaced. If it’s clogged or dirty, it can make it tough for air to flow over the heat exchanger.
  2. Look at your thermostat—For several of us, we may have set our thermostats weeks ago and forgot about it, even more so when using a smart or programmable thermostat. Examine your thermostat to see if anything unusual is occurring or if it may need new batteries. The placement 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 house, such as in direct sunlight or by another heat source, it could be mistakenly assuming your home reached the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have proper 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 take a look at the seals around your windows for any drafts or cold air entering the home.

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