Central air that stopped cooling
AC Repair in Alpharetta for Warm Vents and Stalled Condensers
We find the part that failed, explain the fix and its price, repair it and keep the system running until properly chilled air is flowing again.
Clues Before the Cooling Quits
Cooling systems usually drop clues before they give out entirely. Supply air that is merely cool instead of cold. A condenser that buzzes for a moment and then goes silent. A damp spot on the closet floor beside the furnace. Bedrooms upstairs drifting several degrees above the thermostat reading. Through an Alpharetta summer, with the AC grinding along from May into October, those clues often add up to a full shutdown on the worst possible afternoon. A short pre-call checklist can sometimes spare you a visit. Glance at the wall control: cooling mode, setpoint under the indoor temperature. Peek inside the breaker panel for a switch sitting in the middle position. Slide the filter out and see whether it is caked with dust. Find the float switch on the condensate line and check whether a full pan has cut power. Still warm inside? Shut the system off so an iced coil or straining compressor is not pushed further, then phone us. Our technician meters the system, isolates the true fault and quotes it before touching a part. Afterward you receive a dated job sheet showing what broke, what went in and how the system measured once it was back up.
The Usual Cooling Culprits
Most no-cooling calls trace back to one of the parts or conditions below.
Capacitors
This small cylinder gives the compressor and fan their starting kick. When it weakens, they stall. We meter it under load and swap it if it reads low.
Contactors
Burned or pitted contacts stop power from reaching the outdoor unit. We inspect, replace and confirm the unit starts cleanly.
Fan motors
Outdoor fan motors and indoor blower motors that run slow, hum or seize get diagnosed and replaced with a matching motor.
Refrigerant leaks
Low refrigerant means a leak somewhere. We locate it, explain the repair options and recharge only after the leak is addressed.
Frozen coils
Frost on the evaporator or suction line usually signals weak airflow or a short charge. We thaw it carefully and correct the underlying cause.
Drain lines and pans
Clogged condensate lines and rusted pans cause leaks and shutdowns. We clear the line, check the pan and test the safety switch.
Breaker trips
When the panel keeps cutting power to the condenser, something is drawing too much current. We trace the fault before flipping anything back on.
Controls and wiring
Thermostat wiring, low-voltage faults and control boards that stop sending a call for cooling get tested and repaired.
How an AC Repair Visit Goes
Readings first
First comes a full look: thermostat signal, air handler, condenser. Then the meters come out for voltage, amp draw, refrigerant pressure and the temperature drop across the coil. Those numbers single out the failed component, so nothing gets replaced on a hunch.
Fix and price explained
We tell you which part gave out, what likely caused it and the cost to replace it, all before the old part comes out. On an aging system facing a major repair, we will also mention the replacement route and let you weigh the two.
Repair and test
Once the new component is in, we let the system run a complete cooling cycle and take a second set of readings to compare against the first. You leave with a dated sheet listing the fault, the part, the cost and the after-repair numbers for future reference.
Reasons Our AC Customers Come Back
The cause, not a guess
We test before we replace, so you pay for the part that actually failed and nothing else.
