Why Does My Furnace Keep Shutting Off?

There is typically a sense of dismay when you realize something isn’t quite right with your furnace. You’re relaxing at home and you realize your furnace is endlessly kicking in and shutting off. However, before you panic, there are a few things you can check when you feel like 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 air in your house cleaner, but air filters also support keeping your system clean. Your first step when you notice a concern 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 occurring 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 usually hotter than the rest of your home, such as in direct sunlight or near another heat source, it could be wrongly assuming your home reached the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have the right 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 inspect the seals around your windows for any drafts or cold air entering the home.

While you can review these issues on your own, 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 end up forcing unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
