Tips on Air Conditioning Maintenance
l Have a professional check your system periodically.
l Keep an eye on the refrigerant level.
l Oil the blower motor and fan on both the condensing and the evaporation units annually.
l Keep the condensing-unit pan free of bugs, leaves and dirt.
l Check the tension on the condensing and evaporation unit blower fan belts each spring.
l Inspect the blower ducts and joints for leaks and insulation slippage annually.
l Clean or replace air filters in both window (monthly) and central units (quarterly).
l Clean window units completely each year. Oil the blower motor and fan.
l Check the joint between the window frame and the unit to be sure it is properly caulked and weather-stripped annually.
l Keep the blower motor fan blade free of mold and mildew.
l Set your a/c fan speed on high except in when it’s humid.
l Use a whole-house attic fan.
l Don't crank your thermostat as low as it can go when you turn on your air conditioner.
l Set the thermostat high as comfortably possible in summer.
l Don't put electronic equipment near the thermostat. It senses heat, which causes the a/c to run too long.
