Why Is My Furnace Turning on and Off?

Figure out why your heating and air conditioning equipment is struggling.

Keep your heating and air conditioning equipment in good working condition by paying attention to signs of trouble. If your HVAC equipment is quickly turning off and on, then you likely need the help of a professional. Aside from one easy fix, this problem usually boils down to a serious component failure, requiring a technician who can do the job right.

Here are the most common reasons for quick HVAC cycling:

Dirty filters

A clogged filter will restrict airflow. This prevents warmed air from moving through the system. It backs up in the furnace instead and quickly leads to false readings. Because the heater is hot enough, it shuts down, leaving the house cold and once the air in the unit cools, it kicks on again. Thankfully, this is easily remedied. Talk to your HVAC specialist about the best filters and filter changing schedule for your system.

Clogged outlets

There are pipes leading from your system to the outdoors. They can vent through the attic and roof or an outer wall of your home. If clogged, warm air will pool and lead again to false readings.

Failing electrical components

Sometimes it isn’t the furnace at all, but the thermostat that’s to blame. However, there are sensors inside your heating unit that can fail and cause bad readings as well.
