Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dread when you realize something isn’t quite right with your furnace. You’re sitting at home and you notice 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 help keep your system clean. Your first step when you realize there is a concern with your system should be taking a look at 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 many of us, we may have set our thermostats several months ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything unfamiliar is occurring 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 wrongly 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 examine 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 persist 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 produce more expensive repairs or even a replacement.
