Why Does My Furnace Keep Shutting Off?

There is typically a sense of dismay when you recognize something isn’t quite right with your furnace. You’re relaxing at home and you realize your furnace is continuously kicking in and shutting off. However, before you panic, there are a few things you can check when you feel like 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 indoor air cleaner, but the 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 several of us, we may have set our thermostats weeks 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 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 home, such as in direct sunlight or by 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 proper insulation, your furnace is likely to shut off more regularly. Walk around your home and check the windows to confirm 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 persist after these checks, it might be time to call in the pros. When your furnace is always turning off, it can result in unnecessary work and stress on your system that could produce more expensive repairs or even a replacement.
