Why does my furnace keep shutting off? Published on September 15, 2017 There is typically a sense of dread when you notice something isn’t quite right with your furnace. You’re sitting at home and you notice your furnace is continuously 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. 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 work to keep your system clean. Your first step when you realize there is an issue with your system should be examining 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. Look at your thermostat—For lots of us, we may have set our thermostats months ago and forgot about it, especially when using a smart or programmable thermostat. Check your thermostat to see if anything unusual is going on or if it may 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 house, such as in direct sunlight or close to another heat source, it could be falsely assuming your home has met the desired temperature. 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 coming into the 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 lead to unnecessary work and stress on your system that could produce more expensive repairs or even a replacement.
