Why Does My Furnace Keep Shutting Off?

There is typically a sense of anxiety when you recognize something isn’t quite right with your furnace. You’re resting at home and you realize your furnace is endlessly kicking in and shutting off. However, before you panic, there are a few things you can check when you first notice that 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 air inside your home cleaner, but the filters also support keeping your system clean. Your first step when you realize there is a problem with your system should be taking a look at your air filter to see if it should be replaced. 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 weeks ago and forgot about it, particularly 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 site 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 space, such as in direct sunlight or near another heat source, it could be wrongly assuming your home has met 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 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 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.
