Normal Operating Sounds

nYou may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy days or when the humidity is high. This design feature helps remove moisture and improve efficiency.

nYou may hear the thermostat click when the compressor cycles on and off.

nWater will collect in the base pan during high humidity or on rainy days. The water may overflow and drip from the outdoor side of the unit.

nThe fan may run even when the compressor does not.
