Cooling Problems Rarely Stay Small

Summer in Gwinnett is long and sticky, and an air conditioner that is limping along pays for it every afternoon. Sometimes the signs are loud: the outdoor unit is silent, the breaker keeps flipping, water drips from the furnace closet. Sometimes they are sneaky: a thermostat that never quite reaches its setting, a unit that runs all evening, a suction line wearing a coat of frost. Either way, a quick look before calling can save time. Does the thermostat say cool, with a target below the current reading? Is the breaker for the condenser on? When did the filter last get changed? Many indoor units also have a float switch that cuts power when the drain backs up, so standing water in the pan can explain a dead system. If none of that is it, switch the system off, especially if there is ice or water, and ring us. Our technician reads refrigerant pressures, measures temperature drop across the coil, checks amperage on the compressor and fans and tests the capacitor, contactor, controls and drain. You get the diagnosis and a firm price, then you decide. In older Lilburn homes, we also keep an eye out for equipment that was never sized right to begin with, because no repair fixes that.

Cooling Repairs We Handle

The failures that send most air conditioners into a tailspin, and the fixes.

  • Room-temperature air

    Bad run capacitors, burned contactor points, stalled condenser fans and leaks that drop the charge.

  • Rapid on-off cycling

    Control faults, oversized equipment, a matted coil or a compressor tripping its internal overload.

  • Icy suction line

    Starved airflow or missing refrigerant. We thaw it safely and correct the root problem.

  • Indoor drips

    Algae-plugged condensate lines, corroded pans and float switches that have shut the system off.

  • Breaker keeps tripping

    Chafed wiring, a hard-starting compressor or a motor pulling high amps, confirmed with a meter.

  • Noises that were not there before

    Humming, grinding, clattering or a squeal tied to bearings, fan blades, loose panels or failing motors.

  • Refrigerant leaks

    Leak found and repaired, system evacuated and recharged to the manufacturer's numbers.

Your AC Repair, Step by Step

  1. Quick checks, then instruments

    Thermostat, filter, breaker and drain first. Then pressures, temperatures and amps at both the condenser and the indoor coil.

  2. Diagnosis and price

    We show you what failed and why, and give you a firm number. Anything else that looks worn gets flagged with its own price.

  3. Fix and confirm

    Part replaced, system run through a full cooling cycle, readings taken again to prove the repair held.
