Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is usually a sense of dread when you notice something isn’t quite right with your furnace. You’re relaxing at home and you realize 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 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 inside your home cleaner, but air filters also work to keep your system clean. Your first step when you realize there is an issue with your system should be checking your air filter to see if it needs replacement. 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 several of us, we may have set our thermostats 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 placement 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 by another heat source, it could be falsely 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 confirm they are all closed and examine the seals around your windows for any drafts or cold air entering into your house.

While you can look at these issues yourself, 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 result in unnecessary work and stress on your system that could produce more expensive repairs or even a replacement.
