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