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 relaxing at home and you realize your furnace is continuously kicking in and shutting off. However, before you panic, there are some things you can check when you feel like 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 the filters also support keeping your system clean. Your first step when you realize there is a problem with your system should be taking a look at your air filter to see if it should be replaced. If it’s clogged or dirty, it can make it hard for air to flow over the heat exchanger.
  2. Look at your thermostat—For several of us, we may have set our thermostats months ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything unusual is occurring or if it might need new batteries. The site 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 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 frequently. Walk around your home and check the windows to confirm 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 review 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 result in unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
