Quality Comfort serves Columbus and Polk County with professional heating and cooling services. From the county seat's established neighborhoods to rural properties throughout the area, we provide expert HVAC installation, repair, and maintenance designed for the foothills climate where summer cooling demands are higher than the surrounding mountains.

When it comes to cooling in Columbus, the local conditions matter. As the Polk County seat, Columbus sits at the transition between the Blue Ridge foothills and the mountain uplands. Like nearby Tryon, the thermal belt effect keeps winters milder than communities at similar elevations farther north. However, summer heat and humidity are more intense here, making proper AC sizing and dehumidification critical. Many rural Columbus-area homes rely on propane or electric heating since natural gas service is limited outside the town center. Our AC technicians understand these Columbus-specific factors and size every repair and recommendation accordingly.

When and Why You'd Need to Reset Your AC

Air conditioners have built-in safety controls that shut the system down when something goes wrong — a power surge, a momentary voltage drop, or a component fault. After the event passes, the system doesn't always restart automatically. Resetting it manually is a safe, simple process that resolves many "my AC won't turn on" situations. After summer thunderstorms in Western NC, resetting ACs is one of the most common homeowner tasks.

The Proper Reset Sequence

Step 1: Turn the thermostat to "off." Step 2: Go to your electrical panel and find the HVAC breaker — flip it fully off. Step 3: Locate the outdoor disconnect switch (a box on the wall near your outdoor unit) and turn it off. Step 4: Wait a full 5 minutes. This is important — the compressor has internal pressure that needs time to equalize. Restarting too quickly can damage it. Step 5: Turn the disconnect back on. Step 6: Turn the breaker back on. Step 7: Set the thermostat back to "cool" with your desired temperature. The system should start within a few minutes.

If the Reset Doesn't Work

If the system doesn't restart after a proper reset, or if it starts and then trips the breaker again, there's an underlying problem that reset alone won't fix. A breaker that trips repeatedly indicates a short circuit, a grounded compressor, or a failing component drawing too much current. Do not keep resetting — this can cause electrical damage or fire. Call for professional AC repair at this point.

Some Units Have a Dedicated Reset Button

Certain AC units have a red reset button on the outdoor unit itself, usually near the refrigerant lines. If yours does, press it once firmly after completing the power cycle above. Not all units have this button, and it's not required for a standard reset. If you're unsure about any step, Quality Comfort provides same-day service across Asheville and WNC to get your system running safely.
