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 hear your furnace is constantly kicking in and shutting off. However, before you panic, there are a few things you can check when you feel like 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 indoor air cleaner, but air filters also support keeping your system clean. Your first step when you notice an issue 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 difficult 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. Check your thermostat to see if anything unusual is occurring or if it could need new batteries. The placement 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 wrongly 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 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 the home.

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