Understanding normal operating sounds
When your air conditioner is operating
normally, you will hear sounds such as:
• Droplets of water hitting the condenser,
causing a “pinging” or “clicking” sound.
Water droplets help to cool the condenser.
• Air movement from the fan, especially on
high fan speed settings.
• 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.
• Improve your home’s insulation. Seal all
doors and windows. Close the
fireplace flue.
• Close all blinds and drapes on sunny sides
of the house. Add window awnings.
• Keep the air filter clean.
• Do not block the airflow with drapes or
furniture.
• Ventilate the attic. High temperatures in
the attic add to the air conditioner’s
cooling load.
• 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.
• Use exhaust venting fans when cooking,
doing laundry, or bathing.
