Cooling problems
AC Repair in Sugar Hill, GA
Thermostat says cool, house says otherwise. We find the part that quit and fix it.
Cool Air Back, Without the Guessing
Air conditioners tend to warn you before they quit. Runs stretch longer. The condenser hums but its fan sits still. A damp patch shows up near the air handler. Then one sticky afternoon the registers blow lukewarm and the bedrooms upstairs climb past comfortable. HVAC Sugar Hill repairs central air for houses, rentals and small businesses, and every visit begins with testing rather than hunches. Before dialing, run through four quick checks. Make sure the thermostat reads cool, with a setpoint under the current indoor temperature. Look at the breakers for both the outdoor unit and the indoor one. Slide out the filter and see whether it is gray and matted. Then look near the indoor unit for a float or drain safety switch that may have shut things down because water backed up. If all of that looks fine, the trouble is inside the equipment. Our technician measures voltage, amp draw, pressures and temperatures, names the part that failed and gives you the repair price. You approve it, the fix goes in, and we stay until cold air is moving from every register.
Common AC Repairs We Handle
Most cooling failures land on a handful of parts. These are the ones we test and swap most often.
Capacitors
A weak capacitor keeps the compressor or fan from starting. It is one of the most frequent summer failures and usually a straightforward swap.
Contactors
Pitted or stuck contacts can leave the outdoor unit dead or running nonstop. We test and replace them as needed.
Fan motors
Outdoor and indoor fan motors that hum, overheat or stop spinning get diagnosed and replaced.
Frozen coils
Frost on the coil or copper usually means weak airflow or a low charge. We figure out which and correct it.
Refrigerant leaks
Low charge means a leak somewhere. We locate it, repair it where practical and recharge to the right level.
Drain lines and pans
Clogged drains and cracked pans cause water on the floor or a tripped float switch. We clear and repair them.
Breaker trips
Repeated trips mean an electrical fault somewhere. We locate it before it takes out the compressor.
Controls and noises
Rattles, squeals, grinding and thermostat wiring problems get traced to the source and fixed.
How an AC Repair Visit Runs
Fill us in
Warm air, ice, water, noise or a breaker that keeps flipping. Mention the age of the system and anything you already checked, so the technician knows where to start.
Test, then explain
Our technician checks the condenser outside and the air handler inside, logs electrical and refrigerant numbers and identifies the failed part. You hear what it is, what broke it and the repair price before anything gets swapped.
Fix and confirm
After your okay, the repair happens. Then we let it run and check the supply air temperature at the registers so you know it is truly cooling before we go.
