Why does my furnace keep shutting off?

There is usually a sense of anxiety when you realize something isn’t quite right with your furnace. You’re relaxing at home and you hear 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 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 in your house cleaner, but they also help keep your system clean. Your first step when you recognize an issue with your system should be examining your air filter to see if it needs replacement. 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 lots of us, we may have set our thermostats several months ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything unusual is going on 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 house, such as in direct sunlight or near 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 appropriate insulation, your furnace is likely to shut off more often. Walk around your home and check the windows to confirm 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 by 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 result in unnecessary work and stress on your system that could lead to more expensive repairs or even a replacement.
