Ductless Mini-Split Installation in Commerce City

Reunion (a Shea Homes community dating to 2001), Turnberry, Buffalo Run, River Run and Belle Creek are dominated by two-story homes with ducted systems. The usual ductless jobs there are the bonus room over the garage, a basement converted into a guest suite or theater, and a loft that cooks on summer afternoons. A single-zone system dedicated to that room is the efficient fix, and it lets the family run that room on its own schedule. Basement theaters in particular are better served by a concealed ducted unit tucked into a soffit, which runs quieter than a wall head. HOAs in these communities typically review exterior equipment placement and screening, so plan for that submission.

The city sits around 5,191 feet with a 5°F Adams County design temperature, and mean December lows are about 21°F. We choose cold-climate models by published 5°F capacity with an allowance for altitude. On the open northern lots, wind-driven snow is the main hazard for outdoor units, so they go on the sheltered side, on stands that clear drifts, with defrost water routed to gravel instead of the driveway.

Newer homes in the north generally have 200-amp panels. Older south-end houses may have smaller or crowded panels, and a multi-zone system there sometimes needs a panel check first. For bonus rooms, line sets usually run through the garage ceiling; in older ranches, they run along the foundation in a paintable cover and enter at the rim joist or through a wall.

Mechanical and electrical permits come from the city's Building Safety Division; call 303-289-3790 with questions, though we handle the applications and the inspection scheduling.

Gas is from Xcel, but the electric provider changes partway through town, United Power in some areas and Xcel in others; the city notes the split falls roughly along East 96th Avenue for street lighting. That boundary affects which utility rebate you can use. North-side United Power members should check the co-op's offers. Xcel electric customers should confirm the current Xcel heat pump rebate, which changed in October 2026.

Two programs apply no matter which utility you have. Power Ahead Colorado's $1,500, available because the city belongs to DRCOG, goes toward qualifying cold-climate equipment for an existing house and must be approved before we install. Colorado's 2026 heat pump credit of $1,000 is claimed by the contractor, and $333 or more of it lands on your invoice as a discount. The federal 25C credit stopped covering new installs at the end of 2025.
