The answer to 'mini split short cycling' is that short cycling, where the mini split system turns on and off rapidly, is often caused by issues with the system's refrigerant charge, airflow, or thermostat settings. This can lead to inefficient operation, increased wear on components, and higher energy bills.
Common causes include a refrigerant leak, blocked air filters, a malfunctioning thermostat, or an improperly sized system. Symptoms include the system turning on and off frequently, inconsistent temperatures, and the indoor unit's fan cycling rapidly. Solutions may involve repairing leaks, cleaning or replacing air filters, adjusting thermostat settings, or even replacing the entire mini split system if it is the wrong size for the space.
