Why Does My Furnace Keep Shutting Off?

There is usually 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 endlessly 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 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 they also support keeping your system clean. Your first step when you realize there is a problem 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 several months ago and forgot about it, even more so 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 location 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 home, such as in direct sunlight or near another heat source, it could be mistakenly 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 frequently. 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 coming into the house.

While you can look at these issues by yourself, if issues still continue 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 produce more pricey repairs or even a replacement.
