When it comes to cooling in Asheville, the local conditions matter. Asheville's mix of historic homes in Montford and North Asheville — many built before central HVAC existed — creates unique retrofit challenges. These older homes often have limited ductwork space, uneven heating across floors, and single-pane windows that strain heating systems. Meanwhile, newer South Asheville construction demands properly sized high-efficiency systems to handle the area's 4,400+ heating degree days per year. Our AC technicians understand these Asheville-specific factors and size every repair and recommendation accordingly.

The Relay That Brings Your Outdoor Unit to Life

The contactor is an electrically operated switch inside the outdoor AC unit. When the thermostat requests cooling, a low-voltage signal trips the contactor closed, routing high-voltage power to the compressor and condenser fan motor. When the call for cooling ends, the contactor opens and the outdoor unit stops. It is a straightforward component, but it endures thousands of on-off cycles and eventually wears out — contact surfaces pit and burn, the electromagnetic coil weakens, and the unit either will not start or will not stop.

Two Ways a Contactor Fails

A contactor can stick open, preventing the outdoor unit from starting even when the thermostat is calling for cooling. Or it can weld shut, keeping the outdoor unit running nonstop even after the thermostat is satisfied. A stuck-closed contactor is the more serious failure — it forces the compressor to run around the clock, wasting electricity and accelerating wear. If your outdoor unit refuses to shut off, flip the breaker and call us.

Fast, Budget-Friendly Repair

Contactor replacement ranks among the quicker and more affordable AC repairs. Our technicians stock universal and popular OEM contactors on every truck, so the job is usually done in under an hour. While we are in the unit, we also inspect the capacitor and wiring — components that work in tandem with the contactor and are often a similar age.
