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

A condenser coil coated in dirt and debris reduces its ability to reject heat in Portola Valley. The system runs at elevated head pressure, reducing efficiency and increasing compressor wear in Portola Valley, CA. MBM cleans condenser coils using appropriate products that restore performance without damaging the coil fins in Portola Valley.
Capacitors provide the electrical boost that starts the compressor and condenser fan motor in Portola Valley, CA. A failing or failed capacitor causes the compressor or fan to struggle to start or fail to start entirely in Portola Valley. Capacitor failure is one of the most common AC repair situations in Portola Valley, CA.
The compressor is the most expensive single component in the AC system in Portola Valley. Compressor failure typically results from long-term operation under abnormal conditions including low refrigerant, dirty condenser coils, or failed capacitors in Portola Valley, CA.
