Installing a new AC system in Commerce City requires more than just picking the right brand. At 5,100 feet, the thinner air changes refrigerant behavior and compressor efficiency. We perform a Manual J load calculation on every installation to ensure proper sizing — an oversized system wastes energy through short-cycling, while an undersized system can't keep up during July and August heat waves. Our installations include all permits required by Adams County, proper refrigerant charging for altitude, and a post-installation efficiency test.
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.
