Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is typically a sense of anxiety when you realize something isn’t quite right with your furnace. You’re sitting at home and you notice your furnace is endlessly kicking in and shutting off. However, before you panic, there are a few 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 indoor air cleaner, but air 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 should 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 weeks ago and forgot about it, especially when using a smart or programmable thermostat. Check your thermostat to see if anything strange is going on or if it may need new batteries. The site 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 near another heat source, it could be wrongly 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 regularly. Walk around your home and check the windows to confirm 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 look at these issues on your own, 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 end up forcing unnecessary work and stress on your system that could produce more expensive repairs or even a replacement.
