Why Does My Furnace Keep Shutting Off?

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 endlessly kicking in and shutting off. However, before you panic, there are some things you can check when you feel like your furnace seems to be shutting off more frequently 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 a problem 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 weeks ago and forgot about it, particularly when using a smart or programmable thermostat. Check your thermostat to see if anything unfamiliar is occurring or if it could need new batteries. The location 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 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 frequently. 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 into your house.

While you can look at these issues on your own, if issues still occur after these checks, it might be time to call in the professionals. When your furnace is always turning off, it can lead to unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
