Your AC is running but the house is not cooling in Altadena. Or it is turning on and off every few minutes without ever getting the temperature down in Altadena, CA. Or it stopped running entirely during the hottest stretch of summer and the temperature inside is already climbing in Altadena. Whatever the specific symptom, you need the problem identified and fixed today in Altadena, CA.
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 Altadena. A refrigerant leak that is causing the system to run without reaching setpoint is continuing to lose refrigerant with every operating hour in Altadena, CA. A compressor working against low refrigerant is accumulating wear at an accelerated rate that shortens whatever remains of its service life in Altadena. 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 Altadena, CA. An AC symptom that is merely uncomfortable today can become a complete and more expensive system failure by tomorrow in Altadena.
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 Altadena.

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