Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dismay when you realize 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 some things 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 air filters also support keeping your system clean. Your first step when you notice a concern with your system should be examining your air filter to see if it needs to be replaced. If it’s clogged or dirty, it can make it difficult for air to flow over the heat exchanger.
  2. Look at your thermostat—For several of us, we may have set our thermostats several months ago and forgot about it, even more so when using a smart or programmable thermostat. Examine your thermostat to see if anything unusual is taking place or if it could 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 home, 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 proper 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 inspect the seals around your windows for any drafts or cold air entering the home.

While you can certainly check for some of these issues yourself, if issues still occur after these checks, it might be time to call in the professionals. When your furnace is consistently turning off, it can end up forcing unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
