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 notice your furnace is constantly 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 they also work to keep your system clean. Your first step when you realize there is an issue with your system should be taking a look at 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 many 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 unfamiliar is occurring or if it might 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 home, such as in direct sunlight or close to 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 frequently. Walk around your home and check the windows to make sure they are all closed and inspect the seals around your windows for any drafts or cold air coming into the house.

While you can certainly check for some of these issues by 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 produce more expensive repairs or even a replacement.
