Understanding normal operating sounds
When your air conditioner is operating
normally, you will hear sounds such as:
l Droplets of water hitting the condenser,
causing a “pinging” or “clicking” sound.
Water droplets help to cool the
condenser.
l Air movement from the fan, especially
on high fan speed settings.
l Clicks from the thermostat cycle.
Sounds also may be caused by house
construction - such as vibration of the
unit due to wall construction or unsteady
window mounting area.
Saving energy
You can help save energy by following the
tips below.
l Improve your home’s insulation. Seal all
doors and windows. Close the
fireplace flue.
l Close all blinds and drapes on sunny
sides of the house. Add window
awnings.
l Keep the air filter clean.
l Do not block the airflow with drapes or
furniture.
l Ventilate the attic. High temperatures in
the attic add to the air conditioner’s
cooling load.
l Try not to use heat-producing
appliances during the hottest part of the
day.
l Turn off lights and appliances when they
are not needed.
l Keep heat registers and cool-air
returns closed.
l Use exhaust venting fans when cooking,
doing laundry, or bathing.
