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 resting at home and you notice your furnace is endlessly 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 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 air inside your home cleaner, but they also work to keep your system clean. Your first step when you recognize a concern 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 several of us, we may have set our thermostats months ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything strange is going on 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 usually hotter than the rest of your home, such as in direct sunlight or close to 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 frequently. 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 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 lead to unnecessary work and stress on your system that could lead to more expensive repairs or even a replacement.
