What’s Causing My Furnace in Corona, CA, to Short-Cycle?

If you own a furnace in Corona, CA, you should know that a well-maintained unit runs for 10 to 15 minutes per cycle. If your furnace continually switches on and off in a condition known as short-cycling, it may have dirt buildup, a cracked heat exchanger or another issue.

Dirty Air Filters

Firstly, filters need replacing every 90 days. If you own electrostatic filters, they need cleaning. Dirt-covered filters will do two things: raise the furnace’s internal temperature, causing it to shut down prematurely, and hinder the flow of warm air, causing the system to run more often. Fortunately, our maintenance plans cover filter replacement and cleaning.

Cracked Heat Exchanger

The heat exchanger separates the furnace’s combustion chamber from the blower, which blows the warm air into your home. Most people know that cracked heat exchangers can let carbon monoxide into the home. However, you might not know these cracks can release more heat into the system, resulting in overheating and short-cycling.

Thermostat Problems

Thermostats need calibrating once in a while because they may misread the indoor temperature, especially when close to heat sources. The furnace may turn on and off prematurely at the thermostat’s command.

An Oversized Furnace

Just like with heat pumps, furnaces don’t operate according to the idea that bigger is better. You may have a furnace that produces too much energy for your home’s size. This may be the problem if it heats your home quickly with an uneven distribution of the air.
