Boss Air Conditioning & Heating | HVAC Services in San Juan, TX 78589

Yes, a failed capacitor is one of the most common reasons for an AC shutdown, especially during our hot South Texas summers. The capacitor helps start your outdoor unit's compressor and fan motor. When it fails, the system can't start properly. Our technicians can quickly test and replace a faulty capacitor to restore your cooling, often on the same day.

This is frequently a wiring issue at the thermostat or in your HVAC system. Over time, connections can become loose, or wires can fray, interrupting the 24-volt power signal. Our expert HVAC electricians in San Juan can safely trace the wiring, identify the break or short, and make a secure repair to restore reliable communication between your thermostat and equipment.

The most urgent repairs are those that threaten your system's operation or safety. This includes capacitor failures (which stop cooling entirely), refrigerant leaks, and electrical issues like faulty wiring at the thermostat or contactor. Addressing these promptly prevents further damage to expensive components and ensures your family's comfort and safety. We offer same-day service for many critical repairs.
