Regular AC maintenance in Commerce City is more important than in lower-altitude, humid climates. At 5,100 feet, Colorado's dry air carries more dust and particulate matter, which clogs condenser coils and air filters faster. Our 20-point AC inspection includes checking refrigerant levels (which need altitude-adjusted charging), cleaning condenser and evaporator coils, testing capacitors and contactors, verifying thermostat calibration, and clearing drain lines. Comfort Club members get 2 tune-ups per year (spring AC + fall furnace) for $179.
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.
