Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is usually a sense of dismay when you realize something isn’t quite right with your furnace. You’re resting at home and you hear 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 the filters also work to 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 replacement. If it’s clogged or dirty, it can make it hard for air to flow over the heat exchanger.
  2. Look at your thermostat—For lots of us, we may have set our thermostats several months ago and forgot about it, even more so when using a smart or programmable thermostat. Examine your thermostat to see if anything strange is occurring or if it may 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 home, such as in direct sunlight or by another heat source, it could be mistakenly assuming your home is already up to 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 often. Walk around your home and check the windows to make sure they are all closed and inspect the seals around your windows for any drafts or cold air entering into your house.

While you can review these issues by yourself, if issues still occur after these checks, it might be time to call in the pros. When your furnace is always turning off, it can result in unnecessary work and stress on your system that could cause more pricey repairs or even a replacement.
