Why Does My Furnace Keep Shutting Off?

There is typically a sense of anxiety when you notice something isn’t quite right with your furnace. You’re resting 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 first notice that your furnace seems to be shutting off a lot more 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 notice 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 tough for air to flow over the heat exchanger.
  2. Look at your thermostat—For lots of us, we may have set our thermostats weeks ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything strange is taking place 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 house, such as in direct sunlight or near 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 the right 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 on your own, if issues still occur after these checks, it might be time to call in the experts. 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.
