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 resting at home and you hear your furnace is continuously kicking in and shutting off. However, before you panic, there are several items 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 indoor air cleaner, but air filters also support keeping your system clean. Your first step when you recognize an issue with your system should be checking your air filter to see if it should 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 lots of us, we may have set our thermostats weeks ago and forgot about it, especially when using a smart or programmable thermostat. Check your thermostat to see if anything unfamiliar is taking place or if it might 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 near another heat source, it could be falsely assuming your home has met 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 often. Walk around your home and check the windows to confirm they are all closed and take a look at the seals around your windows for any drafts or cold air coming into the house.

While you can review these issues on your own, 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 cause more costly repairs or even a replacement.
