Why Does My Furnace Keep Shutting Off?

There is usually a sense of anxiety when you recognize something isn’t quite right with your furnace. You’re resting at home and you hear your furnace is constantly kicking in and shutting off. However, before you panic, there are several items you can check when you feel like 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 air filters also support keeping your system clean. Your first step when you notice a concern with your system should be taking a look at your air filter to see if it needs replacement. If it’s clogged or dirty, it can make it tough 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. Examine your thermostat to see if anything unusual is taking place or if it could need new batteries. The site of your thermostat could make a difference, as well. If it’s located in a place that’s usually hotter than the rest of your house, such as in direct sunlight or by another heat source, it could be falsely 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 regularly. Walk around your home and check the windows to ensure they are all closed and examine the seals around your windows for any drafts or cold air entering into your house.

While you can look at these issues yourself, 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 lead to unnecessary work and stress on your system that could lead to more expensive repairs or even a replacement.
