4 Steps to Try When Your Furnace Is Shutting On & Off

Published: January 26, 2022

It’s the winter, and there’s nothing more frustrating than your furnace shutting on and off. Heck, we’ve even had snow here in Alabama this winter, which is even more of a reason to have a furnace that is consistently keeping you warm, not just when it pleases. Did we mention high heat and electricity bills, too?

Thankfully for you, there are a few steps you can try to get your furnace back in working order. Check them out below! 

Check the Filter

More often than not, a dirty or clogged filter is the reason your furnace is shutting on and off. When a filter is clogged, it disrupts the flow of air and your comfort! Always be sure to replace your filters every few months. 

How Do I Change The Filter?

Changing your furnace filter is quick and easy, with great benefits like higher quality air and increasing the efficiency of your heating system. To change your filter, follow these steps:

  1. Turn off your furnace
  2. Find and locate your furnace filter
  3. Determine the size of your filter
  4. Remove the existing (old) filter
  5. Insert the new filter
  6. Return furnace to “on” position

If you run into any problems or trouble while trying to change your filter, you can contact a professional and they will take care of it promptly.


Clean the Vents

If your furnace is turning on and off, always check your vents! If there is dust buildup blocking the flow, this could be your culprit. If your vents look extremely dirty and clogged, there’s a chance you’ll have to get a professional to take care of it, as deep cleans require unique cleaning tools and techniques.


Get a Programmable Thermostat

With a programmable thermostat, you can program it to where your home always stays at a comfortable temperature and is unaffected by the furnace turning off and on. Programmable thermostats are a great option, especially if you’re interested in saving some money on your energy bills. 


Get Your Furnace Serviced

So, you’ve tried all of the above steps to no avail. Now what? Well, we’d say it’s definitely a good time to get your furnace serviced. It can be frustrating to schedule an appointment and have someone come out, but ultimately a professional will be able to properly diagnose your furnace issue and get you back to a comfortable home quicker.
