Understanding normal operating sounds

CARING FOR YOUR AIR CONDITIONER

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.
