Yes, a failed capacitor is a leading cause of sudden AC breakdowns, especially during our hot summers. This critical component helps start the compressor and fan motors. We keep common capacitor types in stock for many Columbia-area systems and can typically diagnose and replace a faulty one on the same day you call, getting your cool air back quickly to avoid discomfort.

We recommend bi-annual maintenance—once in spring for your AC and once in fall for your heater. Our local service includes cleaning coils, checking refrigerant levels, inspecting electrical components like capacitors and contactors, and ensuring your system is free from debris. This proactive care helps prevent the most common failures we see, improves efficiency to combat high humidity, and extends the life of your equipment.
