Our office on Emma Road means fast response times anywhere in the city.

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.

What's Behind That Clicking Sound?

Homeowners throughout Asheville and the WNC mountains frequently reach out to us about clicking sounds coming from their heating and cooling equipment. It is worth noting that brief clicks during startup or shutdown are part of normal operation — relays switching and control boards cycling through their sequences. Where things get concerning is when clicking becomes constant, rapid, or unusually loud while the system runs. The typical causes include a weakening capacitor, a worn contactor, control board malfunctions, or hardware that has loosened and vibrates against the unit housing.

Pinpointing Where the Click Originates

Identifying the location of the clicking sound goes a long way toward narrowing the cause. When the outdoor unit is the source, a relay or contactor failure is often to blame. Indoor clicking may stem from an inducer motor that has seized, a deteriorating ignitor, or a heat exchanger expanding and contracting with temperature shifts. Systems that click over and over without successfully starting typically have a capacitor that can no longer deliver the electrical charge the compressor or fan motor requires. Our NATE-certified technicians at Quality Mechanical stock capacitors, contactors, and relays on every service vehicle for on-the-spot resolution.

Clicking That Poses a Safety Risk

The vast majority of clicking sounds are a nuisance rather than a hazard. The exception is a gas furnace that clicks repeatedly without igniting — this can point to a gas valve or ignitor malfunction, and each unsuccessful ignition attempt risks gas buildup in the combustion chamber. Should you detect the smell of gas along with clicking, power down the system, exit your home, and contact us right away. Quality Mechanical offers emergency HVAC service around the clock across WNC.

Address It Before It Escalates

Clicking problems almost never resolve on their own. Over time, the failing part deteriorates further — a weakened capacitor eventually dies completely, and loose components can break free and cause collateral damage to surrounding parts. Reach out to Quality Mechanical & Fireplaces for an accurate diagnosis. We identify the exact source of the noise and provide a straightforward, upfront estimate before touching anything.
