Why Does My Furnace Keep Shutting Off?

September 15, 2017

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 hear 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 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 help keep your system clean. Your first step when you recognize an issue 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 difficult for air to flow over the heat exchanger.
  2. Look at your thermostat—For many of us, we may have set our thermostats months ago and forgot about it, particularly when using a smart or programmable thermostat. Examine your thermostat to see if anything unusual is taking place or if it may 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 house, such as in direct sunlight or by another heat source, it could be wrongly 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 certainly check for some of these issues yourself, if issues still occur after these checks, it might be time to call in the pros. When your furnace is consistently turning off, it can end up forcing unnecessary work and stress on your system that could lead to more pricey repairs or even a replacement.
