Why Does My Furnace Keep Shutting Off?

There is always a sense of anxiety when you realize something isn’t quite right with your furnace. You’re resting at home and you notice your furnace is constantly kicking in and shutting off. However, before you panic, there are a few things you can check when you first notice that 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 air inside your home cleaner, but the 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 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 many 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 occurring 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 often hotter than the rest of your house, such as in direct sunlight or near another heat source, it could be mistakenly assuming your home reached 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 regularly. Walk around your home and check the windows to ensure they are all closed and take a look at the seals around your windows for any drafts or cold air entering into your house.

While you can review these issues yourself, if issues still occur 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 produce more costly repairs or even a replacement.
