Why Does My Furnace Keep Shutting Off?

There is typically a sense of anxiety when you notice something isn’t quite right with your furnace. You’re resting at home and you notice your furnace is continuously 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 more than usual 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 realize there is an issue with your system should be examining your air filter to see if it needs to be replaced. If it’s clogged or dirty, it can make it hard 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. Look at 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 near 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 appropriate insulation, your furnace is likely to shut off more frequently. 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 entering into your house.

While you can review these issues on your own, if issues still continue after these checks, it might be time to call in the pros. When your furnace is always turning off, it can result in unnecessary work and stress on your system that could cause more pricey repairs or even a replacement.
