A ductless mini-split in Robbinsdale costs $4,200–$12,500 installed, from one head to several, for prewar upstairs rooms. It works well in prewar houses where upstairs rooms were never well served by the old ducts, and it needs no gravity-era ductwork to be rebuilt.
The 1920s and 30s houses in Robbinsdale are the main reason people ask about ductless. They were designed around coal, and the gas furnaces now in them push air through ducts adapted from gravity systems. Upstairs rooms are often the weak point, hot in July and cool in January, and rebuilding the ductwork through old walls is slow and costly.
A mini-split head in an upstairs bedroom gives that room its own cooling and, with a cold-climate model, some heat in the shoulder seasons. The outdoor unit goes beside the house or on a stand, and the line set is a thin bundle that does not need a chase.
In the postwar 1940s and 50s houses, mini-splits help finished attics, additions and enclosed porches that the basement furnace never served. Sealing air leaks first lets each head be a smaller, cheaper size.

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. Prewar upstairs rooms that run hot in July and cool in January usually take one head each, avoiding the cost of rebuilding ductwork through old walls. Compare central AC vs ductless costs.
Before picking an installer for an AC or heat pump, ask whether Xcel's rebate requires a registered contractor. Rebate programs change every year, so check the utility's current terms before you buy.

Usually up the outside wall in a thin bundle, then through one small hole to the head, so nothing is opened inside the old plaster. For an upstairs bedroom we pick the exterior wall closest to the outdoor unit, often a gable or back wall, and cover the run in a painted line-set cover. We walk the route with you before we quote.
Usually not entirely. A cold-climate mini-split can carry a room or two through much of the heating season, but whole-house heat in a Minnesota winter normally still comes from the furnace or boiler. The ductless system is best used to take load off it and to cool rooms the ducts don't reach well.
