Homes in Downtown Gunnison and near Western Colorado University often feature older forced-air systems that struggle when temperatures plunge at 7,700 feet. Thin air changes combustion and venting requirements, so a simple pilot outage or cracked heat exchanger can leave a house without heat within hours. Technicians check for proper draft, inspect flue runs that may have settled on uneven lots near the Gunnison River, and verify blower motors can handle the extra load from longer heating seasons.
Short summers mean furnaces rarely get a full off-season rest, leading to worn belts, dirty burners, and failing limit switches by early October. In Crested Butte commuters' properties, we see more two-stage units that must be tuned for altitude to avoid short-cycling. We carry common parts for brands installed in Gunnison County stock and test carbon-monoxide levels after every repair because elevation magnifies incomplete combustion risks.
When a call comes from a 1950s bungalow near the river, the first step is confirming the thermostat and power before opening the cabinet. Loose wiring from decades of freeze-thaw cycles and rodent activity in crawl spaces is common. We replace only what is needed, document the condition of the heat exchanger, and advise owners on when a full replacement makes more sense than repeated repairs on aging equipment.
Technician insight
In Gunnison the thing that catches most people out with furnace repair is how quickly an older heat exchanger cracks once the first hard freeze hits after our short summer. Homes built before the 1980s near the river or Western Colorado University often have single-stage units that were never tuned for 7,700 feet, so they short-cycle and overheat the exchanger within a few seasons.
No-heat call on a November morning
A homeowner in a 1960s house off North Main reported the furnace running but no warm air. We found a cracked heat exchanger and a failing blower motor that had been straining against high-elevation static pressure. The motor and exchanger were replaced, the system was combustion-tested, and the house was back to temperature before evening temperatures dropped again.

How it works
- 1
Initial Assessment
We arrive, confirm power and thermostat function, then check for immediate safety issues such as gas leaks or CO.
- 2
System Diagnosis
Technicians open the furnace, test ignition, blower, and safety controls while noting altitude-related performance.
- 3
Targeted Repair
Failed components are replaced using parts suited to high-elevation operation and local housing stock.
- 4
Testing And Verification
The furnace is run through cycles, CO levels are measured, and the homeowner receives a written summary.
Pricing
Most furnace repairs fall between a few hundred dollars for parts and labor on a single component and higher when multiple systems need attention.
