Ductless Mini-Split Installation in Louisville

More than 550 Louisville homes were destroyed in 2021, and the city reported 532 rebuilt or under construction as of August 2026. Rebuilt houses are tighter and better insulated than what stood before, so their heating and cooling loads are lower. In some rebuilds a ducted system ends up oversized for bedrooms, and a ductless head in the main suite or a bonus room gives finer control.

If your rebuild is still under construction, note that Power Ahead Colorado excludes new construction. Once the home is complete and occupied, a later add-on may qualify.

Coal Creek Ranch and the other 1980s and 1990s neighborhoods have mostly two-story houses with basements. Two complaints come up constantly: a basement that's chilly in winter and a room over the garage that's hot in summer. A single-zone mini-split solves one room cleanly, and a two-zone outdoor unit can cover both if they sit on the same side of the house.

Plenty of Louisville houses mix eras: an 1890s core, a 1970s addition and a 2010s kitchen bump-out, each with different insulation. We calculate each room separately so a head in the old part isn't undersized and one in the new part isn't oversized. Oversized heads cycle on and off, waste energy and leave summer air clammy.

Wall heads are the default, but floor consoles work well under low windows in Old Town bedrooms, and a ceiling cassette can disappear into a remodeled kitchen.

The Marshall Fire was driven by gusts up to 112 mph. We bolt outdoor units to rated stands or brackets and keep them clear of drift corners so they can defrost. Line sets go in rigid covers rather than loose foam that wind and sun shred within a few years.

Mini-split filters catch dust and pet hair but not much wildfire smoke. If smoke is a concern, plan on a portable HEPA purifier as well.

Boulder County's heating design temperature is 0°F, so we choose cold-climate models with published capacity in single digits and size each head from a room-by-room load. Condensate from indoor heads runs to an interior drain or a pump, because exterior drain tubes freeze in January. Each outdoor unit needs its own 240-volt circuit and disconnect; we check panel space first, especially in older Old Town homes.

Louisville Building Safety handles mechanical permits for heat pumps, with a final inspection required. We file it and are on site when the inspector comes. Xcel Energy supplies gas and electricity; its heat pump rebates changed October 1, 2026, so confirm current amounts with Xcel.

Louisville is in DRCOG, so Power Ahead Colorado's $1,500 cold-climate rebate can apply to existing homes when we submit before work starts. The state chips in a $1,000 credit for 2026 through your contractor, with $333 or more credited on your bill. The federal 25C credit has ended.
