Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is usually a sense of anxiety when you notice 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 they also work to keep your system clean. Your first step when you realize there is a problem with your system should be checking your air filter to see if it should 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 many 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 could 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 space, such as in direct sunlight or close to 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 proper insulation, your furnace is likely to shut off more often. Walk around your home and check the windows to confirm they are all closed and examine 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 experts. When your furnace is consistently turning off, it can result in unnecessary work and stress on your system that could produce more expensive repairs or even a replacement.
