Ductless mini-splits in Shakopee cost about $4,200–$12,500 installed, from one head to a multi-zone system. They suit rooms the ducts never reached, such as a bonus room, finished attic or an older house with no ductwork at all.
Shakopee's two housing eras call for ductless in different ways. In the older blocks near downtown and First Avenue, some homes date to the 1800s and still run on boilers. There's no duct system to tap, and cutting new chases through plaster and small basements is costly. One or two wall heads with a thin line set can add cooling to those houses without that work, and the boiler keeps doing the heating.
In the 1990s to 2000s subdivisions, the question is usually a single stubborn space: a room over the garage, a finished attic or a three-season porch that the builder's ducts barely reach. A head in that room takes the load off the main system.
For Shakopee's many small shops and offices, we install mini-splits and also service commercial rooftop units.

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. Boiler-heated downtown houses from the 1800s need only a head or two with thin line sets, and a newer home's bonus room or finished attic adds a head. Compare central AC vs ductless costs.

Yes. A boiler house has radiators or baseboard but no air ducts, so a mini-split gives it cooling without opening walls. Heads go on the rooms you use most, with a line set run to a single outdoor unit. The boiler can stay as your main heat, or the mini-split can take over shoulder-season heating. We walk the house and write a flat-rate quote.
Yes. Those rooms are usually at the end of the builder's duct run or have no duct, so they run hot in July. One head sized to the room cools it on its own thermostat, with a short line set to an outdoor unit placed near that side of the house. The written quote lists the head and its location.
