Common AC Problems We Fix
Urban density, mature landscaping, and continuous cooling loads generate recognizable equipment failures. Coil freezing, power system faults, refrigerant loss, mechanical compression issues, and air movement problems all require expert attention.
Frozen Evaporator Coil
Ice covering evaporator coils prevents heat removal from indoor air while blocking ventilation to living spaces. Frost indicates either restricted airflow preventing coil warmth or low refrigerant allowing coil temperatures to drop below freezing during operation.
Clogged filters, sealed vents, weak blowers, or refrigerant leaks create freezing conditions. Dunwoody's humid climate provides moisture that rapidly freezes on cold coil surfaces when temperatures drop excessively.
Diagnostics measure airflow resistance, verify blower performance specifications, calculate refrigerant temperatures, and check ductwork integrity. Correcting airflow restrictions or refrigerant loss stops ice formation and restores heat exchange.
Electrical Component Failures
Cooling systems contain electrical parts experiencing thermal stress, voltage variation, and switching cycles. Capacitor degradation, contactor failure, and board malfunction prevent operation or trip breakers repeatedly.
Capacitors lose charge storage over time, unable to provide motor starting energy. Contactors develop damaged surfaces from arcing. Boards fail from power events or environmental factors.
Testing measures capacitance values, inspects contacts for damage, and verifies board outputs. Dunwoody homes with smart thermostat retrofits sometimes have wiring mismatches requiring professional correction.
Refrigerant Leak Detection And Repair
Escaping refrigerant reduces cooling ability until systems run constantly without meeting temperature settings. Low refrigerant causes warm air, frozen parts, and compressor overheating.
Detection equipment finds leaks in coils and connections. Pressure testing confirms repairs. Evacuation removes moisture before charging to specifications.
Service involves R-410A and R-32 requiring proper handling and precise charging.
Compressor And Condensing Unit Issues
Compressors circulate refrigerant through systems. Failure creates grinding sounds, electrical cutoff, or units running without cooling.
Damage comes from electrical stress, flooding, or oil loss. Testing checks windings, voltage, and current draw.
Fan failures, blocked coils, and bad capacitors prevent condenser operation. Testing, inspection, and cleaning restore function.
Airflow And Humidity Control Problems
Poor circulation causes temperature variations, moisture buildup, and long runtimes. Drain clogs, dirty blowers, and duct problems restrict flow.
Drain blockages trigger switches or cause damage. Equipment clears lines and verifies traps.
Blower contamination reduces performance and creates noise. Bearings fail. Controls malfunction. Service restores proper airflow.
High humidity signals cycling issues, low refrigerant, or capacity problems. Testing identifies causes.
