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.

Why Is Your HVAC System Clicking?

A clicking noise from your HVAC system is one of the most common complaints we hear from homeowners across Asheville and Western North Carolina. A few clicks at startup or shutdown are perfectly normal — that's the sound of relays engaging and the control board sending signals. But persistent, rapid, or loud clicking during operation usually signals a problem that needs professional attention. The most frequent culprits are a failing capacitor, a defective contactor, a malfunctioning control board, or loose hardware vibrating against the cabinet.

Diagnosing the Source

Location matters when tracking down a clicking noise. Clicking from the outdoor unit often points to a relay or contactor issue, while clicking from the indoor unit may indicate a stuck inducer motor, a failing ignitor, or an expanding and contracting heat exchanger. If your system clicks repeatedly but won't start, the capacitor is the most likely suspect — it's trying to energize the compressor or fan motor but can't deliver enough charge. Our NATE-certified technicians carry capacitors, contactors, and relays on every truck so we can resolve this on the spot.

When Clicking Means Danger

Most clicking noises are annoying but not dangerous. However, clicking from a gas furnace combined with a failure to ignite can indicate a gas valve or ignitor problem — and repeated failed ignition attempts can allow gas to accumulate. If you smell gas alongside clicking, turn the system off, leave the house, and call us immediately. Quality Comfort provides emergency HVAC service 24/7 throughout WNC.

Don't Ignore It

A clicking noise rarely fixes itself. Left unaddressed, the underlying component failure usually worsens — a weak capacitor becomes a dead capacitor, and a loose part can break free and damage other components. Call Quality Comfort for a proper diagnosis. We'll tell you exactly what's causing the sound and give you an honest, upfront quote before any work begins.
