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

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