Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is usually a sense of dread when you notice something isn’t quite right with your furnace. You’re relaxing at home and you notice 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 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 support keeping your system clean. Your first step when you realize there is an issue with your system should be checking your air filter to see if it needs replacement. 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 months ago and forgot about it, even more so when using a smart or programmable thermostat. Examine your thermostat to see if anything unfamiliar is occurring 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 close to another heat source, it could be falsely assuming your home is already up to the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have appropriate insulation, your furnace is likely to shut off more often. Walk around your home and check the windows to ensure 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 by yourself, if issues still continue after these checks, it might be time to call in the professionals. When your furnace is consistently turning off, it can lead to unnecessary work and stress on your system that could produce more expensive repairs or even a replacement.
