Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dismay when you recognize something isn’t quite right with your furnace. You’re sitting at home and you notice 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 air inside your home cleaner, but the filters also help keep your system clean. Your first step when you notice a problem 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 difficult for air to flow over the heat exchanger.
  2. Look at your thermostat—For several 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 might 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 near 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 confirm 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 persist after these checks, it might be time to call in the pros. When your furnace is always turning off, it can lead to unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
