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 relaxing 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 realize 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 air in your house cleaner, but air filters also work to keep your system clean. Your first step when you notice an issue with your system should be examining 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 many of us, we may have set our thermostats several months ago and forgot about it, especially when using a smart or programmable thermostat. Look at your thermostat to see if anything strange is occurring 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 typically hotter than the rest of your space, such as in direct sunlight or close to 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 proper insulation, your furnace is likely to shut off more regularly. 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 by yourself, if issues still occur after these checks, it might be time to call in the professionals. When your furnace is always turning off, it can end up forcing unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
