Why Heat Pumps in Marietta, GA, Short Cycle

You shouldn’t have to deal with short cycling as you run your heat pump in Marietta, GA. Nonetheless, it can occur; the system can shut down before it completes a reasonable 10- to 15-minute cycle, and your home may not be any warmer than it was before. Heat pumps short cycle usually because of an airflow block, a dirty coil, a faulty thermostat or a mismatch between system and house size.

Block to Airflow

Homeowners should change their air filters every one to three months. Left alone, filters get dirty and hinder air circulation, putting stress on the motor and overheating it. Any time your heat pump overheats, it’ll shut down automatically for safety reasons, resulting in a short cycle.

Dirty Condenser Coil

The condenser coil in your compressor, which absorbs heat from outside in heating mode, can get dirty fairly quickly, exposed as it is to the elements. This dirt and dust build-up could contribute to overheating and force the heat pump to shut down prematurely.

Uncalibrated Thermostat

Maybe it’s just the thermostat telling the heat pump to shut down sooner than it should. This can happen when the thermostat’s sensors lose their calibration and mistakenly measure the indoor temperature to be higher. Maintenance can include thermostat calibration, among many other vital tasks.

Oversized Heat Pump

Bigger doesn’t always mean better in the HVAC field, as heat pumps have a unique blowing capacity that may make them too powerful for small homes. If your system is too big for your home, it will quickly and unevenly heat it.
