AC Repair in Sandy Springs, GA

Has the thermostat been creeping a degree or two higher every afternoon? Does the outdoor unit start, stop and start again within a few minutes? Is there a crust of ice on the larger copper line, or a damp spot on the ceiling under the attic air handler? An air conditioner usually announces trouble well before it quits altogether, and in a Sandy Springs summer that seems to last from May into October, those early signs are worth heeding. The cause is nearly always specific. A run capacitor loses strength in the heat. A contactor's points burn and stop closing. A condenser fan motor wears out its bearings. A slow refrigerant leak drains the charge over a season. Algae plugs the condensate line until the safety switch shuts everything down. A careful technician measures voltage, amperage, pressures and temperatures and lets those numbers identify the failed part, rather than replacing components until something changes. Before you phone, a few checks can save time: check that the thermostat shows Cool and a setpoint lower than the room, look at the breaker, inspect the filter and see whether a float switch at the drain pan has tripped. If none of that helps, switch the system off so any ice can thaw.
