Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is typically a sense of dread when you recognize something isn’t quite right with your furnace. You’re resting at home and you realize your furnace is continuously 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 frequently 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 recognize an issue with your system should be examining your air filter to see if it needs to be replaced. If it’s clogged or dirty, it can make it hard for air to flow over the heat exchanger.
  2. Look at your thermostat—For lots of us, we may have set our thermostats weeks ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything unusual is occurring or if it might need new batteries. The site 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 mistakenly 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 regularly. Walk around your home and check the windows to ensure they are all closed and take a look at the seals around your windows for any drafts or cold air entering the home.

While you can review these issues by 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.
