Ductless Mini-Split Installation in Superior

Rock Creek Ranch homes date mostly from the 1990s and early 2000s. Like many production houses of that era, they often have a bonus room above the garage that the main system barely reaches, and basements that were finished long after the HVAC was designed. One head per problem room is usually the fix, and it leaves the existing furnace and AC alone.

Owners of new, carefully designed rebuilds often don't want a white box on every bedroom wall. Ceiling cassettes sit flush in the drywall, and a slim ducted air handler hidden in a closet or attic can feed two or three bedrooms through short runs. Both connect to the same multi-zone outdoor unit as the wall heads in the main rooms.

The trade-off is cost and access: cassettes need ceiling framing planned in advance, and ducted units need a filter you can actually reach. We sort that out at the design stage, ideally before drywall.

The few surviving Original Town houses and the new homes built there sit on small lots near the street. We place condensers on side or rear walls, keep line sets in painted covers and route condensate inside where possible. See our mini-split guide for older homes for how this works in smaller houses.

The Town of Superior's construction requirements use a 154 mph design wind speed, among the highest in the metro. For outdoor units that means rated stands or wall brackets, proper anchors, and placement that keeps the unit out of wind tunnels between houses where possible. We also raise the condenser above snow drifts so it can shed defrost water and keep heating.

Boulder County's heating design temperature is 0°F, and Superior sits at about 5,522 feet. We size each head from a room-by-room load and choose models with published capacity at 5°F and below. Each outdoor unit needs a dedicated 240-volt circuit and a disconnect within sight. Many rebuilds were wired with spare capacity, but we confirm before quoting.

The Town of Superior Building Department enforces the 2018 IRC and IMC and the 2021 IECC with local amendments. Permit filing and the inspection appointment are on us.

Superior is in DRCOG, so Power Ahead Colorado's $1,500 rebate can apply to existing homes; houses still under construction are excluded. Colorado's 2026 credit is $1,000 for qualifying air-source heat pumps, with at least $333 discounted on the invoice. Superior is also a partner in Boulder County's Switch Together group-buy, with 2026 offers due November 8. Xcel's heat pump rebates changed October 1, 2026; confirm with Xcel. The federal 25C credit has ended.
