Ductless mini-split installation in Chaska costs $4,200–$12,500 with a written flat-rate quote, for downtown brick houses with thick walls. They are a common answer in the downtown Chaska brick houses, where thick walls leave no room for cooling ducts.
Chaska's downtown houses were built of local clay brick from 1857 on, and a solid masonry wall leaves nowhere to hide a new duct. That is the main reason ductless heads turn up in these houses: one head on an interior wall cools a room, a small line set carries the refrigerant, and nothing opens the plaster. Shallow basements and coal-era chimneys add to the case, since cooling equipment and a furnace crowd the same small space.
Jonathan, begun in 1966, is the other regular job. Townhomes there put the condensers in a shared row, so a mini-split's outdoor unit has to fit the association's rules and the available clearance, and a wall-mounted unit can sometimes go where a big condenser cannot. In the newer two-stories off Highway 212, a head in the upstairs bedroom that lags behind the main floor is cheaper than rebuilding the return air. A brick house also holds heat well into a summer evening, so a mini-split's quick response helps.

Our $4,200–$12,500 installed price comes as a written flat-rate quote, with a 2-year labor warranty on top of the manufacturer's parts warranty. Drilling through solid brick and routing a line set around a coal-era chimney take longer than a frame wall, and each additional head on one outdoor unit adds cost. Compare central AC vs ductless costs.
Mostly, yes. The line set runs through a small hole in the wall behind each head, and the refrigerant lines can follow a closet or the outside of the wall. We look at where the brick, the chimney and the basement ceiling leave room, and we quote the exact routes in writing so there are no surprises on installation day.
We cannot promise it. The city's electric program has covered air-source and ground-source heat pumps and central air conditioners, and funds are limited and handed out first come, first served. Call the City of Chaska utility before you buy and ask whether mini-splits qualify this year and whether it needs a registered contractor.
