The answer to 'ductless system short cycling' is that ductless mini-split systems can sometimes short cycle, which means the system turns on and off rapidly without reaching the desired temperature. Common causes include refrigerant leaks, dirty air filters, oversized systems, or issues with the thermostat or control board.
Short cycling can lead to higher energy bills, uneven cooling/heating, and potential damage to the compressor. Solutions may include repairing refrigerant leaks, cleaning or replacing air filters, adjusting thermostat settings, or having a professional technician evaluate the system and make necessary repairs or adjustments.
