Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is typically a sense of anxiety when you notice something isn’t quite right with your furnace. You’re sitting at home and you hear your furnace is endlessly 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 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 air in your house cleaner, but they also support keeping 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 hard for air to flow over the heat exchanger.
  2. Look at your thermostat—For lots 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. Check your thermostat to see if anything unfamiliar is occurring or if it could need new batteries. The location 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 is already up to 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 ensure 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 yourself, if issues still continue after these checks, it might be time to call in the experts. When your furnace is always turning off, it can lead to unnecessary work and stress on your system that could lead to more expensive repairs or even a replacement.
