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 hear your furnace is continuously kicking in and shutting off. However, before you panic, there are several items you can check when you first notice that 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 in your house cleaner, but they also work to keep your system clean. Your first step when you notice an issue with your system should be taking a look at your air filter to see if it needs to be replaced. 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 several 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 unusual is taking place or if it may 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 mistakenly assuming your home has met the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have appropriate insulation, your furnace is likely to shut off more frequently. Walk around your home and check the windows to make sure they are all closed and examine the seals around your windows for any drafts or cold air coming into the house.

While you can certainly check for some of these issues by yourself, if issues still occur 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 pricey repairs or even a replacement.
