NORMAL OPERATING SOUNDS
• You 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.
• You may hear the thermostat click when the compressor cycles on
and off.
• Water 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.
• The fan may run even when the compressor does not.
• Water droplets being thrown against the outside coils can make a
pinging noise. This helps cool the condenser. You can reduce this
