Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is usually a sense of dismay when you notice something isn’t quite right with your furnace. You’re resting 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 realize 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 they also support keeping your system clean. Your first step when you notice a problem 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 tough 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, particularly when using a smart or programmable thermostat. Check your thermostat to see if anything unusual is going on or if it could need new batteries. The location 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 house, such as in direct sunlight or close to another heat source, it could be mistakenly assuming your home reached 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 often. Walk around your home and check the windows to make sure they are all closed and take a look at the seals around your windows for any drafts or cold air entering the home.

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