Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is typically a sense of dread when you notice something isn’t quite right with your furnace. You’re sitting at home and you notice your furnace is continuously 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 a lot more 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 help keep your system clean. Your first step when you realize there is a problem with your system should be taking a look at your air filter to see if it needs replacement. If it’s clogged or dirty, it can make it difficult for air to flow over the heat exchanger.
  2. Look at your thermostat—For many of us, we may have set our thermostats weeks ago and forgot about it, even more so when using a smart or programmable thermostat. Check your thermostat to see if anything unusual 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 often hotter than the rest of your space, 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 regularly. Walk around your home and check the windows to confirm they are all closed and inspect the seals around your windows for any drafts or cold air entering the home.

While you can review these issues by 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 result in unnecessary work and stress on your system that could cause more pricey repairs or even a replacement.
