A ductless mini-split in Anoka costs $4,200–$12,500 installed, single-zone to multi-zone, with a written flat-rate quote. It is the usual answer for upstairs rooms in the 1860s to early-1900s houses that never had ducts above the first floor.
The oldest houses near downtown and the Rum River have tall ceilings, plaster walls, little wall insulation and attics that never held a duct. Cooling them with a basement air conditioner rarely works, because there is nothing to carry the air upstairs. One or two ductless heads upstairs fix the bedrooms without cutting into plaster, and the line set can usually run through a closet or along an exterior corner.
We choose between ductless and a small-duct high-velocity system by looking at the house. A high-velocity system suits a home where several rooms need air and you want no visible heads. Ductless suits one or two problem rooms and costs less. River humidity makes dehumidification worth planning with either, and cottonwood fluff from both riverbanks collects on outdoor coils each June.

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. The price follows how many upstairs bedrooms in the old downtown houses get a head, and whether the line set can run through a closet instead of plaster. Compare central AC vs ductless costs.
It depends on how many rooms need cooling. Two bedrooms upstairs are cheaper and simpler with ductless heads. A whole second floor of small rooms, where you do not want a head on every wall, is where a small-duct high-velocity system earns its cost. We look at the plaster, the attic and the closets before recommending one.
Yes. The head hangs on a mounting plate fastened to the framing behind the plaster, and the refrigerant lines go through one small hole. We locate studs first and plan the hole so it stays out of cast-iron radiator pipes and wiring.
