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 sitting at home and you realize your furnace is continuously kicking in and shutting off. However, before you panic, there are some things you can check when you realize 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 they 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 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 several 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 could 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 reached 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 often. Walk around your home and check the windows to make sure they are all closed and examine the seals around your windows for any drafts or cold air coming into the house.

While you can review these issues on your own, if issues still occur after these checks, it might be time to call in the pros. When your furnace is always turning off, it can end up forcing unnecessary work and stress on your system that could produce more pricey repairs or even a replacement.
