Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of anxiety when you notice something isn’t quite right with your furnace. You’re resting at home and you hear your furnace is continuously kicking in and shutting off. However, before you panic, there are a few things you can check when you realize 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 work to keep your system clean. Your first step when you recognize a problem with your system should be taking a look at your air filter to see if it needs replacement. 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, even more so when using a smart or programmable thermostat. Look at your thermostat to see if anything unfamiliar is occurring or if it may need new batteries. The placement of your thermostat could make a difference, as well. If it’s located in a place that’s typically hotter than the rest of your space, 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 proper 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 examine the seals around your windows for any drafts or cold air entering the home.

While you can look at 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 costly repairs or even a replacement.
