Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dread when you realize something isn’t quite right with your furnace. You’re relaxing at home and you realize your furnace is endlessly kicking in and shutting off. However, before you panic, there are several items 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 air filters also help keep your system clean. Your first step when you realize there is a concern with your system should be checking 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 lots of us, we may have set our thermostats several months ago and forgot about it, especially when using a smart or programmable thermostat. Look at your thermostat to see if anything unfamiliar is occurring or if it might need new batteries. The placement of your thermostat could make a difference, as well. If it’s located in a place that’s usually hotter than the rest of your home, such as in direct sunlight or close to 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 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 examine the seals around your windows for any drafts or cold air entering into your house.

While you can review these issues yourself, if issues still continue after these checks, it might be time to call in the pros. When your furnace is consistently turning off, it can end up forcing unnecessary work and stress on your system that could produce more expensive repairs or even a replacement.
