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 sitting 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 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 inside your home cleaner, but air filters also help keep 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 many of us, we may have set our thermostats several months ago and forgot about it, especially when using a smart or programmable thermostat. Examine your thermostat to see if anything unusual is going on or if it might need new batteries. The placement 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 home, such as in direct sunlight or by 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 regularly. Walk around your home and check the windows to make sure they are all closed and inspect the seals around your windows for any drafts or cold air entering the home.

While you can certainly check for some of these issues by yourself, if issues still persist after these checks, it might be time to call in the pros. When your furnace is consistently turning off, it can end up forcing unnecessary work and stress on your system that could cause more pricey repairs or even a replacement.
