A new furnace installation in Columbine involves more than swapping equipment. At 5,200-5,800 feet, we adjust the gas valve orifice, set the manifold pressure for altitude, perform combustion analysis to verify safe CO levels, inspect and seal existing ductwork, and ensure proper venting. Colorado's 2026 Ultra-Low NOx regulations affect which models can be installed. We only install compliant equipment and handle all Jefferson County permits.
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.
Our technicians serve all Columbine neighborhoods including various residential areas. Whether you're in a newer development or an established neighborhood, we have the expertise and licensing to handle your HVAC needs.
