Furnace Repair & Installation
At 8,000 feet, thin air changes how a gas furnace burns, so we set up and repair Aspen furnaces for clean combustion, steady ignition, and no cold starts after a long vacancy.

HVAC Services in Aspen, CO
Aspen sits at 8,000 feet in the Roaring Fork Valley, with four ski mountains, luxury second homes, and long, snowy winters. We repair, install, and maintain the HVAC equipment that keeps Aspen's chalets, second homes, and downtown Victorians heated at 8,000 feet through long, snowy winters.
What Aspen Altitude, Snow, and Chalets Do to Heating and Cooling
Altitude changes combustion. At 8,000 feet, gas furnaces and boilers burn in much thinner air than at lower elevations. With air that thin over Red Mountain and Starwood, careful setup, venting, and combustion checks are what keep an Aspen furnace or boiler burning safely and steadily.
Vacant-home freeze risk. A second home with a failed furnace can drop below freezing in hours on a cold night, and burst pipes follow. We service furnaces and boilers, check thermostats, and help owners keep heat steady while they are away.
Deep snow buries outdoor units. On Red Mountain and in Starwood, drifts can swallow a heat pump or AC outdoor unit for weeks at a time, and the ice that forms around it chokes airflow and stalls defrost. We dig units out, check defrost cycles, and set up snow clearance so a chalet system keeps breathing through a long Aspen winter.
Radiant heat in chalets. Many Aspen chalets heat with radiant floors and hydronic loops, and a cold loop or a stuck valve leaves one zone cold. We trace loops, repair faults, and restore even heat.
Dry, high-altitude air. Aspen air stays dry and thin, and winter heating dries it further. Whole-home humidifiers keep indoor air comfortable and protect woodwork in fine homes.
Snow forecasts matter most for slopeside homes above town and second homes sitting empty for weeks, so look to the National Weather Service forecast office in Grand Junction for the Aspen forecast, and for thin, parched air at 8,000 feet in a Red Mountain chalet, the EPA indoor air quality pages explain indoor air care for high-altitude homes.
What We Repair and Install in Aspen
Aspen work means altitude, snow, and homes that often sit empty for weeks, so these twelve services are built around freeze protection, combustion at 8,000 feet, and systems that must restart cleanly after a long absence.
Boiler Repair & Installation
Many Aspen chalets heat with boilers and radiant loops, and we repair leaks, cold zones, and pressure trouble in West End and Red Mountain homes.
Learn more →Heat Pump Installation & Repair
Heat pumps in Aspen need defrost cycles that keep up with deep snow, and we install and repair units that hold their output through a cold, snowy winter.
Learn more →AC Repair & Installation
Cooling season in Aspen is short, so when an AC unit blows warm air or cycles oddly we trace the fault to airflow, charge, or controls and get it running again.
Learn more →Ductless Mini-Split Services
A mini-split heats and cools a McLain Flats guest house or a Starwood remodel without new ductwork, and we keep its outdoor unit clear of snow load.
Learn more →Evaporative Cooler Services
A swamp cooler fits a dry Aspen summer, and we keep pads, pumps, and water lines working for the few months a year one earns its keep.
Learn more →Indoor Air Quality
At 8,000 feet the air inside an Aspen home can feel thin and parched, and humidifiers, filters, and ventilation bring it back to comfortable.
Learn more →Maintenance & Tune-Ups
A tune-up before the first snowfall catches worn parts in an Aspen system, and it matters most for homes that sit empty between visits.
Learn more →Commercial HVAC
Downtown Aspen shops, restaurants, and lodges near the Wheeler Opera House need steady heat and cooling, and we service their rooftop units and split systems.
Learn more →Emergency HVAC Repair
A dead furnace on an Aspen night is an emergency, and one call sends a technician to you.
Learn more →Radiant & Hydronic Heating
Radiant heat runs through many Aspen chalets, and we repair cold loops and install new ones under stone and hardwood floors.
Learn more →ERV Installation
Sealed Aspen homes trap mountain air inside, and an ERV swaps it for fresh air while holding onto warmth.

Aspen Landmarks That Orient a Service Call
Aspen Mountain, known as Ajax, rises over downtown, the Maroon Bells sit southwest of town, and the Wheeler Opera House and the Aspen Art Museum anchor the cultural core. Aspen Valley Hospital serves the area, and Aspen/Pitkin County Airport (ASE) sits south of town.
Heating and Cooling at 8,000 Feet in Aspen
Aspen is a high-alpine town with a climate unlike any Front Range city. At 8,000 feet, winters run long and cold, snow piles deep, and summer stays mild with highs in the 70s. Aspen Mountain, known as Ajax, rises right over downtown, and Snowmass, Buttermilk, and Highlands round out the four mountains. Heating dominates the year here, and cooling is a short-season job.
Housing in Aspen runs from Victorian-era downtown homes to modern chalets and mountain estates on Red Mountain and in Starwood. Many homes are second homes and vacation rentals that sit empty for weeks, and an empty home with a failed furnace can freeze pipes fast. Radiant heat, boilers, and forced-air systems all appear across town, and each needs care suited to altitude and cold.
What Aspen Homeowners Ask Us
Yes. We serve West End, Aspen Highlands, Red Mountain, Starwood, McLain Flats, and Downtown Aspen, along with the rest of town. Tell us your neighborhood when you call so we can plan the visit.
Keep the heat steady, not off, and have the furnace or boiler checked before you leave. A failed furnace in an empty home can drop below freezing in hours on a cold night. We service heating systems and check thermostats so heat stays steady while you are away.
Yes, with the right setup. A cold-climate heat pump sized for 8,000 feet heats a West End home or a McLain Flats guest house through long Aspen winters and cools it during the short mild summer. We pick the unit for the house, verify defrost cycles, airflow, and refrigerant charge, and keep snow and ice cleared from the outdoor unit so it keeps working between visits.
A stuck valve, a clogged loop, or trapped air often leaves one radiant zone cold. We trace the loop, repair the fault, and restore even heat to every zone.
Aspen air stays dry and thin at 8,000 feet, and heating dries it further. That dry air shows up as static, cracked wood, and scratchy throats. A whole-home humidifier puts moisture back into a Red Mountain chalet's thin, dry air, and sealed ductwork keeps that moisture from leaking away between visits.
Have the furnace or boiler checked before you leave town, clear snow from outdoor units and vents at your Starwood or Red Mountain place, and confirm the thermostat holds a steady temperature while you are away. We inspect burners, ignition, safety controls, and airflow, and we flag worn parts before a cold night in the West End tests them.
