Short-cycling occurs when your furnace goes on and off repeatedly for short periods, preventing the house from reaching its proper temperature. A typical residential furnace cycles on and off three to eight times each hour, resulting in heating cycles of seven to twenty minutes. Your furnace is probably out of whack if it happens every minute or two.
Dirty Filters And Blower Wheels
If you don’t change your air filters frequently enough, they will become clogged and filthy, causing the heat exchanger to overheat.
A filthy blower wheel may be causing your furnace to turn on and off too rapidly. The blower wheel contains blades that push air, and if they are clogged with dirt, they will not operate as well.
Closed Air Supply Vents
Check your air vents to determine if any of them are obstructed in any way if your furnace keeps switching off. If the heat exchanger doesn’t get enough air, it won’t convey enough heat. As a result, the heat will build up, possibly causing your furnace to short cycle.
Thermostats that are damaged might cause furnace problems. It regulates the temperature of your whole heating system. Several factors might be causing your thermostat to malfunction. It might be that the wiring has to be replaced, batteries need to be replaced, or the thermostat is in the wrong spot.

If the thermostat is near any heat source, such as direct sunlight, the temperature reading will be skewed, causing the thermostat to switch on and off in an erratic pattern. You’ll need to hire a professional who does furnace installation in Pasadena to repair any outdated wiring or transfer it to a more suitable position.
