Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is typically a sense of anxiety when you recognize something isn’t quite right with your furnace. You’re relaxing at home and you notice your furnace is constantly kicking in and shutting off. However, before you panic, there are several items you can check when you first notice that your furnace seems to be shutting off more than usual 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 an issue 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, especially when using a smart or programmable thermostat. Check your thermostat to see if anything unusual is taking place or if it may need new batteries. The location of your thermostat could make a difference, as well. If it’s located in a place that’s often hotter than the rest of your house, such as in direct sunlight or by another heat source, it could be falsely assuming your home has met 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 make sure they are all closed and examine 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 continue after these checks, it might be time to call in the professionals. 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.
