Ductwork services in Commerce City 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 Commerce City homes with older ductwork, sealing alone typically reduces energy bills by 15-25% — often the best return on investment of any HVAC upgrade.
Commerce City sits at 5,100 feet in the high plains northeast of Denver, where summer highs regularly exceed 95°F and winter lows drop below 0°F. The area's exposure to prairie winds increases heating costs in winter.
