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 construc-
tion-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.
. 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.
. Turn off lights and appliances when they are
not needed.
. Keep heat registers and cool-air returns closed.
l
Use exhaust venting fans when cooking, doing
laundry or bathing.
