Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is usually a sense of dread when you recognize something isn’t quite right with your furnace. You’re sitting at home and you notice your furnace is constantly 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 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 in your house cleaner, but the filters also help keep your system clean. Your first step when you realize there is a concern with your system should be checking your air filter to see if it needs to 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 several 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 strange is taking place 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 reached the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have the right insulation, your furnace is likely to shut off more frequently. Walk around your home and check the windows to make sure 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 certainly check for some of 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 end up forcing unnecessary work and stress on your system that could lead to more pricey repairs or even a replacement.
