The Switch That Powers Your Outdoor Unit
The contactor is an electrically operated switch in your outdoor AC unit. When your thermostat calls for cooling, it sends a low-voltage signal to the contactor, which closes and delivers high-voltage power to the compressor and condenser fan motor. When the thermostat is satisfied, the contactor opens and the outdoor unit shuts off. It's a simple part, but it handles thousands of on-off cycles and eventually wears out — contacts pit and burn, the coil weakens, and the unit either won't start or won't stop.
Common Contactor Failure Modes
A contactor can fail in two ways: stuck open (the outdoor unit won't start even though the thermostat is calling for cooling) or stuck closed / welded (the outdoor unit won't shut off even when the thermostat is satisfied). A stuck-closed contactor is more than an annoyance — it runs the compressor continuously, wasting energy and potentially causing compressor damage. If your outdoor unit keeps running after the thermostat turns off, shut it off at the breaker and call us.
A Quick, Affordable Repair
Contactor replacement is one of the faster and more affordable AC repairs. Our technicians carry universal and common OEM contactors on our trucks, so this is typically completed in under an hour. We also inspect the capacitor and wiring during the repair, since these components work together and are often a similar age.
HVAC Challenges in Asheville
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.
Seasonal Tip for Asheville Homeowners
Asheville's elevation means nighttime temperatures can drop into the 20s even in early spring. We recommend keeping your heating system serviced through April and scheduling AC maintenance by mid-May to prepare for the humidity that builds through summer.
