Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is usually a sense of dread when you notice something isn’t quite right with your furnace. You’re resting at home and you realize your furnace is endlessly kicking in and shutting off. However, before you panic, there are some things you can check when you first notice that your furnace seems to be shutting off more frequently 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 the filters also work to keep your system clean. Your first step when you notice a problem with your system should be checking 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 lots of us, we may have set our thermostats months ago and forgot about it, particularly when using a smart or programmable thermostat. Check your thermostat to see if anything unfamiliar is going on or if it may need new batteries. The location of your thermostat could make a difference, as well. If it’s located in a place that’s often hotter than the rest of your space, such as in direct sunlight or by 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 appropriate insulation, your furnace is likely to shut off more often. Walk around your home and check the windows to ensure 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 by yourself, if issues still continue after these checks, it might be time to call in the professionals. When your furnace is consistently turning off, it can result in unnecessary work and stress on your system that could produce more pricey repairs or even a replacement.
