Short cycling prevents your furnace from reaching the thermostat’s set point. When this happens, the system shuts off before it heats your home. Learn about five reasons your furnace in Hartwell, GA, could short cycle.
Dirty Furnace Filter
When your heater’s filter gets dirty, it can cause the system to overheat. As a result, the high-limit switch will turn off your furnace within five minutes. Be sure to inspect and change your heater’s filter every month to prevent short cycling.
Debris in the Exhaust Vent
The purpose of the exhaust vent is to transport hazardous fumes out of your home. Ice, snow, beehives, bird nests and other debris can obstruct your exhaust vent. Not only can debris in your exhaust vent cause short cycling, but carbon monoxide gas can stay in your home.
Thermostat Installation
It’s important to mount your thermostat in the right location, not the wall near the utility closet or above a heat grate. If the thermostat is in a poor location, your heating system may turn off prematurely.
Installing a thermostat may seem like a simple DIY project. However, an improper thermostat installation can cause your furnace to operate inefficiently. If you need a new thermostat, hire a professional HVAC company for thermostat installation services.
Oversized Furnace
There are many factors that go into selecting the right heater for your home. These include energy output, climate and size. A furnace that’s too large for your home causes high energy bills, fluctuating temperatures and short cycling.
Faulty Flame Sensor
A flame sensor is one of your furnace’s safety elements. Its purpose is to detect a flame after you turn on the system. If it breaks or accumulates dirt, it’ll extinguish your furnace’s flame quickly.
