A ductless mini-split setup in Mounds View costs $4,200–$12,500 installed, quoted flat-rate in writing. They are an option for ramblers that have only ever had window units, where the ducts cannot carry cooling to the back bedrooms.
Mounds View's ramblers and split-levels were built with ducts sized for heat. Supply registers sit where they heat best, not where they cool best, and back bedrooms often have no return at all. For owners who have lived with window units for decades, a mini-split offers central-style cooling without rebuilding that ductwork. One or two heads can cover the bedrooms, and each room gets its own control.
The other common job is a finished basement or an enclosed porch. Houses rebuilt after the 1965 tornado look like their neighbors from the outside, and their basements follow the same open layout, so there is usually a simple route for the line set. We mount the outdoor unit on a wall bracket or a pad, away from windows and from where snow slides off the roof. Because the houses are mostly pre-1980, we check the electrical panel for a free breaker slot.

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. Ramblers cooled only by window units usually need one or two heads for the back bedrooms, and the head count sets the price. Compare central AC vs ductless costs.
Usually one head for the main living area and one per bedroom you want cooled, though a hallway head can sometimes serve two rooms with the doors open. We walk the house and propose a layout and price in writing. A multi-zone outdoor unit keeps the outside to a single cabinet.
For cooling certain rooms, yes. If the problem is only the back bedrooms, a ductless head can be cheaper and less invasive than rebuilding returns. If the central system needs replacing anyway, we price both routes so you can compare the written quotes and choose.
