Why Does My Furnace Keep Shutting Off?

There is usually a sense of dismay when you realize something isn’t quite right with your furnace. You’re sitting at home and you notice your furnace is continuously kicking in and shutting off. However, before you panic, there are several items 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 indoor air cleaner, but they also help keep your system clean. Your first step when you recognize a problem with your system should be checking your air filter to see if it needs replacement. 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, especially when using a smart or programmable thermostat. Look at your thermostat to see if anything unusual is taking place or if it may need new batteries. The location of your thermostat could make a difference, as well. If it’s located in a place that’s typically hotter than the rest of your space, such as in direct sunlight or near another heat source, it could be wrongly 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 yourself, 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 cause more expensive repairs or even a replacement.
