Your AC is running but the house is not cooling in South Duxbury. Or it is turning on and off every few minutes without ever getting the temperature down in South Duxbury, MA. Or it stopped running entirely during the hottest stretch of summer and the temperature inside is already climbing in South Duxbury. Whatever the specific symptom, you need the problem identified and fixed today in South Duxbury, MA.
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 South Duxbury. A refrigerant leak that is causing the system to run without reaching setpoint is continuing to lose refrigerant with every operating hour in South Duxbury, MA.

An AC symptom that is merely uncomfortable today can become a complete and more expensive system failure by tomorrow in South Duxbury.
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 South Duxbury.
