Why Does My Furnace Keep Shutting Off?

There is always a sense of dread when you realize something isn’t quite right with your furnace. You’re resting at home and you notice your furnace is continuously 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 air filters also help keep your system clean. Your first step when you notice an issue with your system should be taking a look at your air filter to see if it needs to 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 several months ago and forgot about it, particularly when using a smart or programmable thermostat. Examine your thermostat to see if anything strange is going on or if it may need new batteries. The placement of your thermostat could make a difference, as well. If it’s located in a place that’s typically hotter than the rest of your space, such as in direct sunlight or near another heat source, it could be wrongly 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 entering the home.

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 end up forcing unnecessary work and stress on your system that could lead to more pricey repairs or even a replacement.
