Ductwork services in Columbine Valley address one of the most overlooked sources of energy waste. The average home loses 20-30% of conditioned air through duct leaks, and Colorado's extreme temperature swings (30-50°F in a single day) stress duct joints through constant expansion and contraction. We provide duct inspection, leak testing, sealing, insulation, repair, and replacement. For Columbine Valley homes with older ductwork, sealing alone typically reduces energy bills by 15-25% — often the best return on investment of any HVAC upgrade.
Like most Denver metro communities, this area experiences hot summers exceeding 90°F, cold winters dropping below 0°F, and rapid temperature swings of 30-50°F in a single day. The high altitude (5,200+ feet) requires all gas furnaces to have proper high-altitude combustion adjustments.
