We understand the unique demands of HVAC at 4,100+ feet.

When it comes to cooling in Highlands, the local conditions matter. At over 4,100 feet, Highlands is the highest-elevation community in our service area and one of the coldest east of the Rockies. Standard heat pumps simply cannot keep up here — cold-climate or dual-fuel systems are mandatory. The area's extreme rainfall (80+ inches annually) combined with cool temperatures creates relentless moisture that accelerates ductwork corrosion and mold growth. Many luxury homes have complex multi-zone systems that require advanced balancing expertise. Our AC technicians understand these Highlands-specific factors and size every repair and recommendation accordingly.

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.
