Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dread 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 some things you can check when you first notice that 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 the filters also work to 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 replacement. 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 several of us, we may have set our thermostats months ago and forgot about it, especially when using a smart or programmable thermostat. Check your thermostat to see if anything strange is occurring or if it may need new batteries. The location 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 house, such as in direct sunlight or near 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 the right insulation, your furnace is likely to shut off more often. Walk around your home and check the windows to ensure they are all closed and examine the seals around your windows for any drafts or cold air coming into the house.

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