Ductless mini-split installation in Carver costs $4,200–$12,500, written flat-rate, a fit for historic district brick and stone houses. They suit the historic district's brick and stone houses, where ducts are the hardest part, and the walkout levels and hot bedrooms up the hill.
Carver's old town was laid out in the steamboat era, and its houses were heated by stoves and coal before they were converted, sometimes more than once. Stone or brick foundations, small basements and a chimney that now vents only the water heater leave no obvious path for cooling ducts. A ductless head on an interior wall, fed by a refrigerant line set, cools a room without opening plaster, and it also pulls moisture out of damp river-flat air as it runs.
Up the hill the case is different. Walkout lower levels facing the valley run cooler than the floors above, and the upstairs bedrooms run warmest in July because one system serves three levels from a hallway thermostat. A single head in the hottest bedroom, or on the walkout, takes load off the central system without touching the ducts. Because Carver sits on the Minnesota River bluffs, check that any outdoor unit is clear of roof runoff and drifting snow.

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. Routing a line set through stone or brick in the historic district takes longer than a frame hillside wall, and each extra head adds cost. Compare central AC vs ductless costs.
Xcel Energy customers have heat pump and cooling rebates; ask whether the rebate needs a registered contractor. Minnesota Valley Electric Cooperative members have their own rebates, and the heat pump rebates generally require enrolling in an off-peak program and using a Quality Installation contractor. Rebate programs change every year, so check the utility's current terms before you buy.

Usually, yes. The line set between the outdoor unit and each indoor head is a small bundle that can follow a closet, a chase or the outside of the wall, so most of the work is a three-inch hole through the wall behind the head. We look at where the stone or brick foundation and the existing chimney chase leave room before we quote.
Often it fixes that room, and it can take some strain off the main system in July. A head sized to the bedroom cools it independently of the thermostat in the hallway. If the whole upper floor runs hot because of the ducts, a second head or a duct repair may be a better answer, and we tell you that after measuring.
