Why Does My Furnace Keep Shutting Off?

There is typically a sense of dread when you notice something isn’t quite right with your furnace. You’re resting at home and you realize your furnace is endlessly 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 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 indoor air cleaner, but they also support keeping your system clean. Your first step when you realize there is a concern with your system should be checking your air filter to see if it needs to 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 many of us, we may have set our thermostats weeks ago and forgot about it, especially when using a smart or programmable thermostat. Check your thermostat to see if anything unfamiliar 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 typically hotter than the rest of your home, such as in direct sunlight or close to 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 regularly. Walk around your home and check the windows to make sure they are all closed and take a look at the seals around your windows for any drafts or cold air coming into the house.

While you can review these issues yourself, if issues still occur after these checks, it might be time to call in the experts. When your furnace is always turning off, it can result in unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
