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 Keller. Or it is turning on and off every few minutes without ever getting the temperature down in Keller, TX. Or it stopped running entirely during the hottest stretch of summer and the temperature inside is already climbing in Keller. Whatever the specific symptom, you need the problem identified and fixed today in Keller, TX.
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 Keller. A refrigerant leak that is causing the system to run without reaching setpoint is continuing to lose refrigerant with every operating hour in Keller, TX. A compressor working against low refrigerant is accumulating wear at an accelerated rate that shortens whatever remains of its service life in Keller. 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 Keller, TX. An AC symptom that is merely uncomfortable today can become a complete and more expensive system failure by tomorrow in Keller.
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 Keller.

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