Why Does My Furnace Keep Shutting Off?

There is always a sense of anxiety when you notice something isn’t quite right with your furnace. You’re resting at home and you realize your furnace is continuously kicking in and shutting off. However, before you panic, there are a few 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 air filters also work to keep 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 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, even more so when using a smart or programmable thermostat. Look at your thermostat to see if anything unusual is going on or if it may need new batteries. The location 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 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 examine the seals around your windows for any drafts or cold air coming into the house.

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