Why is My Furnace Short-Cycling in Granbury, TX?

If your furnace in Grandbury, TX, keeps turning on and off rapidly, it’s short-cycling. This is a sign you need to schedule furnace repair or replacement services. What can cause a furnace to short-cycle?

Clogged Air Filter

A clogged air filter is often the cause of a furnace short-cycling. When you have a clogged air filter, your furnace won’t have proper airflow. The furnace overheats and its safety controls shut it down.

You should replace the furnace air filter on a regular basis. This may be every three months, but it could be more often. You’ll need to change it more often if you have pets, live in a dusty environment or suffer from allergies.

Malfunctioning Thermostat

A broken thermostat in your Granbury, TX, home can also cause your furnace to short-cycle. The thermostat may be telling your furnace to turn off before it should. Try shutting off your thermostat and replacing its battery to see if this solves the problem.

Oversized Furnace

It may be the case that service technicians installed too large of a furnace in your home. When a furnace is too large, it heats your home too quickly and then shuts down. A correctly sized furnace will generate heat that efficiently heats your home over time.

Deteriorated Flame Sensor

When your gas furnace burns fuel, it produces a small amount of water. This water can over time corrode the flame sensor, causing the furnace to short-cycle. To prevent this problem, schedule maintenance for your furnace every fall.

Regular maintenance can also catch other problems with your furnace that could cause it to short-cycle. You should schedule this service every fall.
