Highlands' prestigious mountain community demands premium HVAC service matched to extreme high-elevation conditions. Quality Mechanical provides specialized heating, cooling, and dehumidification services to Highlands homes, from luxury estates to charming downtown properties. 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.
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.

Seasonal Tip for Highlands Homeowners
Highlands' extreme elevation means frost can occur any month of the year. Never fully shut off your heating system, even in summer. We recommend maintaining a 58°F minimum year-round and having your system inspected twice annually — once before the long heating season and once mid-winter to catch any issues before the coldest months.
