Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dismay when you realize something isn’t quite right with your furnace. You’re resting at home and you realize your furnace is continuously kicking in and shutting off. However, before you panic, there are several items you can check when you feel like 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 air inside your home cleaner, but they also support keeping your system clean. Your first step when you realize there is a concern with your system should be examining 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 lots of us, we may have set our thermostats weeks ago and forgot about it, even more so when using a smart or programmable thermostat. Look at your thermostat to see if anything unusual is taking place or if it could 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 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 proper insulation, your furnace is likely to shut off more frequently. Walk around your home and check the windows to ensure they are all closed and examine 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 persist 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 lead to more pricey repairs or even a replacement.
