Ductless mini-splits in Savage cost $4,200–$12,500 installed, single-zone to multi-zone, quoted flat-rate in writing. They suit finished basements, bonus rooms and bedrooms that run warm at the far end of a long duct run in the 1990s and 2000s homes.
A Savage mini-split job often begins with a complaint about one level. In a walkout on the river bluffs the lower level is finished and the furnace is tucked behind it, with the supply ducts running upstairs from there. The result is a basement that overcools in summer and an upstairs bedroom that lags. A ductless head in the lower level gives it its own control, and the main system stops fighting itself.
Townhome associations are common here too, and many have a bonus room or a sunroom added later. A head on an exterior wall serves those rooms without touching the shared walls. Houses that still have an older R-22 air conditioner may choose to leave it running and add a head to the room that gets the worst of the heat. That puts off a full replacement without ignoring the problem.

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. Walkouts on the river bluffs often need one head for the finished lower level, and a townhome association may restrict where the outdoor unit goes. Compare central AC vs ductless costs.
Minnesota Valley Electric Cooperative ties its AC and heat pump rebates to load-control and off-peak programs, which change the wiring. Ask whether the rebate needs a registered contractor. Rebate programs change every year, so check the utility's current terms before you buy.

Yes, when the cause is one duct system trying to serve two very different spaces. A ductless head in the lower level can condition it on a separate schedule, so the central AC no longer runs to chase the basement. It won't fix a wet basement, but it keeps the air in the finished space comfortable.
Sometimes. If one room, like a loft or sunroom, is the problem, a single head is cheaper than replacing the whole system. Associations often set rules for where the outdoor unit and line set can go, so we confirm that first. If the whole unit is old, replacing the central system may serve you better.
