"Our AC completely stopped cooling during a brutal heat wave. The technician from Local HVAC Repair Pros arrived in undefined, undefined the very same afternoon, found a failed capacitor, and had us running cool within the hour. Absolutely incredible service!"
"My AC kept tripping the circuit breaker. I booked an appointment, and the repairman found a compressor drawing too many amps due to low refrigerant. He recharged it and the system has run perfectly ever since. Very knowledgeable and polite."
"Extremely professional and punctual. My heat pump was making a terrible grinding noise and barely keeping up. The technician replaced a worn blower motor bearing and the system now runs quieter than it ever has. Highly recommend them."
