Help! My Furnace Keeps Turning On and Off

Basement in Atlanta with a furnace for heating

If your furnace keeps turning on and off repeatedly, it can be a major source of frustration. Not only does this disrupt the heating in your home, but you also end up spending more money than necessary on gas or electric bills. This is because when the furnace turns off, it cools down and then needs to come back on again before the temperature returns to normal levels. With that said, if you want to resolve this problem once and for all, here are some tips that can get to the bottom of why your furnace is turning on and off.

Troubleshooting an Erratic Furnace

  • Check the filter: This is one of the most common causes of a furnace that keeps turning on and off. A dirty or clogged filter can prevent the air from flowing freely, which will cause the furnace to turn on and off repeatedly. Make sure to replace your filter every few months (or as recommended by your manufacturer).
  • Clean the vents: Another common issue that can cause a furnace to kick on and off constantly is if they are blocked or dusty. Make sure to clean all of your vents regularly so that the air can flow through them properly.
  • Invest in a programmable thermostat: If you have a programmable thermostat, you can set it to keep your home at a comfortable temperature without the furnace having to turn on and off. This can save you a lot of money on your energy bills in the long run.
  • Get your furnace serviced: If you’ve tried all of the above tips and your furnace is still turning on and off, it might be time for a service call. A professional can take a look at your furnace and determine what’s causing the problem so that it can be fixed.
