Complete system diagnosis before any repair is recommended. Specific fault identified and explained. Upfront pricing. Correct repair with correct parts. System performance verified before we leave. Every repair guaranteed.
Your AC is running but the house is not cooling in Duncan. Or it is turning on and off every few minutes without ever getting the temperature down in Duncan, SC. Or it stopped running entirely during the hottest stretch of summer and the temperature inside is already climbing in Duncan. Whatever the specific symptom, you need the problem identified and fixed today in Duncan, SC.
The urgency with AC problems is that most of them get worse with every hour the system operates with the underlying fault in place in Duncan. A refrigerant leak that is causing the system to run without reaching setpoint is continuing to lose refrigerant with every operating hour in Duncan, SC. A compressor working against low refrigerant is accumulating wear at an accelerated rate that shortens whatever remains of its service life in Duncan. A frozen evaporator coil from restricted airflow is building ice that will eventually shut the system down completely if the restriction is not addressed in Duncan, SC. An AC symptom that is merely uncomfortable today can become a complete and more expensive system failure by tomorrow in Duncan.
Addressing the specific fault when it first produces a symptom is always less expensive than addressing the compounded damage it produces when left to develop in Duncan.

Every major AC failure mode is progressive in Duncan. Refrigerant leaks out continuously in Duncan, SC. A failing capacitor produces thermal stress on the compressor with every startup attempt in Duncan. A frozen coil builds more ice with every operating cycle in Duncan, SC. And a compressor working under any abnormal condition accumulates wear faster than under correct operating conditions in Duncan. The fault that produces a moderate symptom today produces a more severe symptom and more expensive damage tomorrow in Duncan, SC.
An AC running but blowing warm or room-temperature air has a specific failure in the refrigerant circuit or condenser in Duncan, SC. Low refrigerant from a leak is the most common cause in Duncan. A failed condenser fan allowing the coil to overheat is another common cause in Duncan, SC. A failed compressor is a less common but more significant cause in Duncan.
A system running continuously without reaching thermostat setpoint has a cooling capacity problem in Duncan. Low refrigerant reducing capacity. A dirty condenser coil reducing efficiency. An undersized system. Or an air distribution problem preventing conditioned air from reaching the thermostat location in Duncan, SC.
A failing capacitor that cannot sustain the compressor through a full cycle in Duncan, SC. An oversized system that cools the thermostat before the rest of the home reaches setpoint in Duncan. A refrigerant charge that is incorrect causing safety switches to trip. Or a dirty filter causing the evaporator coil to freeze and trigger freeze protection in Duncan, SC.
A specific electrical or control fault preventing startup in Duncan. Failed capacitor. Tripped breaker. Failed contactor. Failed control board. Thermostat wiring fault in Duncan, SC. MBM diagnoses no-start conditions beginning with the most common and least expensive causes in Duncan.
Grinding or squealing from the air handler indicates a failing blower motor bearing in Duncan, SC. Rattling from the outdoor unit may indicate debris or a loose component in Duncan. Banging or clanking from the compressor indicates an internal compressor fault in Duncan, SC. Bubbling or hissing indicates refrigerant escaping through a leak in Duncan.
Water leaking from the indoor air handler typically indicates a clogged condensate drain line in Duncan. A clogged drain causes the condensate pan to overflow, producing water damage to the surrounding structure in Duncan, SC. MBM clears clogged condensate drains and treats the drain line with biocide to prevent rapid reoccurrence in Duncan.
A frozen evaporator coil indicates either restricted airflow or low refrigerant in Duncan, SC. A frozen coil should not be forced to operate. Turn the system to fan-only mode to allow the ice to melt before MBM's technician diagnoses and addresses the underlying cause in Duncan. Do not try to chip or break the ice off the coil in Duncan, SC.
Refrigerant does not deplete under normal operation in Duncan, SC. Low refrigerant indicates a leak in the refrigerant circuit in Duncan. The leak must be found and repaired before refrigerant is added, or the added refrigerant leaks out and the problem recurs in Duncan, SC.
A condenser coil coated in dirt and debris reduces its ability to reject heat in Duncan. The system runs at elevated head pressure, reducing efficiency and increasing compressor wear in Duncan, SC. MBM cleans condenser coils using appropriate products that restore performance without damaging the coil fins in Duncan.
Capacitors provide the electrical boost that starts the compressor and condenser fan motor in Duncan, SC. A failing or failed capacitor causes the compressor or fan to struggle to start or fail to start entirely in Duncan. Capacitor failure is one of the most common AC repair situations in Duncan, SC.
The compressor is the most expensive single component in the AC system in Duncan. Compressor failure typically results from long-term operation under abnormal conditions including low refrigerant, dirty condenser coils, or failed capacitors in Duncan, SC. A failed compressor requires replacement in Duncan.
Modern AC systems rely on electronic control boards that manage compressor staging, fan operation, and safety shutdowns in Duncan, SC. A failed control board can produce a wide range of symptoms depending on which function it was managing in Duncan.
The drain pan and line accumulate algae, mold, and debris that eventually produces a blockage in Duncan. A clogged condensate drain causes the pan to overflow and water to leak from the air handler in Duncan, SC. MBM clears clogged drains and treats the line to prevent rapid reoccurrence in Duncan.
