Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dread when you recognize something isn’t quite right with your furnace. You’re resting at home and you realize your furnace is constantly 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 air filters 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 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. Check your thermostat to see if anything unfamiliar is occurring or if it could 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 home, such as in direct sunlight or by another heat source, it could be mistakenly 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 confirm 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 by yourself, if issues still continue 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 expensive repairs or even a replacement.
