Why Does My Furnace Keep Shutting Off?

There is usually a sense of anxiety when you notice something isn’t quite right with your furnace. You’re sitting at home and you notice your furnace is endlessly kicking in and shutting off. However, before you panic, there are a few 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 help keep your system clean. Your first step when you recognize an issue with your system should be examining your air filter to see if it needs replacement. 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 several 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 strange is taking place 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 often hotter than the rest of your space, such as in direct sunlight or by another heat source, it could be falsely assuming your home has met the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have appropriate insulation, your furnace is likely to shut off more often. Walk around your home and check the windows to confirm they are all closed and examine 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 experts. When your furnace is consistently turning off, it can result in unnecessary work and stress on your system that could cause more costly repairs or even a replacement.
