Poor cooling is often caused by insufficient refrigerant, dirty filters and heat exchanger, or a blockage in the air circulation system. Sometimes the cause is a faulty temperature sensor or a weak compressor. It's recommended to have a technician inspect the unit to accurately determine the problem before recharging.
Water leaks are often caused by a blocked drain hose, dirt buildup in the drain pan, or frozen refrigerant coils due to low refrigerant. Cleaning the indoor unit and checking the drain line usually resolves the problem.
Abnormal noises may indicate a problem with the indoor unit's fan, a loose component, or the beginning of compressor damage. Continued operation with abnormal noises could lead to further damage, so immediate inspection is recommended.
Yes, frequent on/off cycles (short cycling) can be caused by a faulty thermostat, an oversized unit, or an electrical problem. This results in higher electricity consumption and reduces the compressor's lifespan.
