Boulder furnace repair, done right.

If your furnace has quit, you want it fixed once and fixed right. In Boulder, that means knowing the local housing: historic homes near downtown, mid-century homes in south Boulder, and a significant number of rental properties. Boulder has some of the most ambitious local climate and electrification goals in Colorado, which shapes how many owners think about their next system. Besties HVAC Solutions repairs every major furnace brand with flat, upfront pricing and a spotless finish.

Local factors in Boulder

Many Boulder owners repairing an older furnace also want to understand their electrification path, so we lay out the repair and the long-term option side by side.

• City and county programs have offered support for heat pumps and efficiency upgrades. Offerings change, so we check what is current.
• Rental properties in the city have been subject to SmartRegs energy efficiency requirements tied to rental licensing.
• Historic homes in areas like Mapleton Hill may have boilers, limited duct space and preservation considerations.

What a Boulder furnace repair visit includes

Every repair starts with a full diagnosis, not a guess. We test ignition, flame sensing, pressure and limit switches, the inducer and blower motors and the control board, then check gas pressure, temperature rise and combustion. You get a written price for the repair you need, and nothing else. Afterward we run a full heating cycle and a carbon monoxide test before we leave.

• Done-right guarantee on every repair
• Combustion and carbon monoxide safety test
• Gas pressure and temperature rise checked against altitude guidance
• Flame sensor, igniter and burner inspection
• Filter check, replaced if needed

Altitude matters here. At about 5,400 feet there is less oxygen for combustion, so gas furnaces need the setup the manufacturer specifies for elevation. Incorrect setup is a quiet cause of overheating and early failures, so we check it on every Boulder repair visit.
