Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dread when you recognize something isn’t quite right with your furnace. You’re resting 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 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 inside your home cleaner, but the filters also work to keep your system clean. Your first step when you realize there is an issue 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 many of us, we may have set our thermostats months ago and forgot about it, particularly 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 often hotter than the rest of your space, such as in direct sunlight or near another heat source, it could be falsely assuming your home has met the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have proper 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 take a look at the seals around your windows for any drafts or cold air coming into the house.

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 lead to unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
