Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is usually a sense of dread when you realize something isn’t quite right with your furnace. You’re sitting at home and you hear your furnace is constantly kicking in and shutting off. However, before you panic, there are some things you can check when you realize your furnace seems to be shutting off a lot more 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 the filters also support keeping your system clean. Your first step when you notice 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 difficult for air to flow over the heat exchanger.
  2. Look at your thermostat—For lots of us, we may have set our thermostats months ago and forgot about it, especially when using a smart or programmable thermostat. Check your thermostat to see if anything unusual is going on or if it might need new batteries. The site 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 is already up to 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 make sure they are all closed and examine the seals around your windows for any drafts or cold air coming into the house.

While you can look at these issues on your own, if issues still persist 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 lead to more pricey repairs or even a replacement.
