We've been the NATE-certified team that Highlands area residents trust since 2005.

Highlands' prestigious mountain community demands premium HVAC service matched to extreme high-elevation conditions. Quality Comfort 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.

Every HVAC System Has a Filter — Here's How to Find Yours

Whether you have a furnace, heat pump air handler, or packaged unit, there's a filter that needs regular changing. The location varies: horizontal air handlers (common in WNC attics and crawl spaces) typically have a filter slot on the side or bottom of the unit. Upflow furnaces have the filter at the bottom, near the return duct connection. Some homes have a filter grille in the wall or ceiling of a central hallway — this is your return air grille, and the filter slides in from the front. If you've never found your filter, check all of these locations.

Handling Different Filter Configurations

Some systems have multiple return vents, each with its own filter. If you have return grilles in several rooms, check each one for a filter. Others have a single large filter at the air handler and no filters at the returns. A few older installations have filters at both locations — the returns AND the air handler — which causes excessive airflow restriction. If you find filters in both places, remove the return vent filters and use only the air handler filter. Ask a technician to confirm the ideal setup during your next HVAC maintenance visit.

The Swap: Step by Step

Turn off the HVAC system before changing the filter (running it without a filter, even briefly, lets dust into the system). Remove the old filter and note the arrow on the frame showing airflow direction — it should point toward the air handler or furnace. Insert the new filter with the arrow matching this direction. If there's no arrow, the side with the wire reinforcement grid faces the air handler. Close the filter door or grille securely. Turn the system back on.

Setting a Maintenance Schedule That Sticks

The best filter-change schedule is one you actually follow. Set a phone reminder for the first of each month during the heating and cooling seasons. Stock up on filters — buy a 4-pack so you always have replacements on hand. For Asheville and WNC homeowners, April and October are good months to start fresh filters as you transition between heating and cooling seasons.
