HSPF2 and COP: Heat Pump Ratings for Minnesota Winters
HSPF2 is a seasonal average; COP is efficiency at one temperature. For a Minnesota winter, compare capacity and COP at 5°F. Our heat pumps run $7,500–$14,500.

Ductless mini-split installation in Blaine costs $4,200–$12,500 installed, from one head to several zones. Mini-splits suit rooms the ducts never served well, such as a finished lower level or the bedroom at the end of a long run.
In Blaine a mini-split is usually the answer to one stubborn room. The 1950s and 60s ramblers in the south end got central air later, pushed through ducts built for heat with one return, so the far bedrooms stay warm on hot afternoons. A single wall head in that room fixes it without touching the rest of the system, and in winter the same head adds heat.
North of there, walkout lower levels face the ponds and wetlands, and the air down there turns damp and musty by midsummer. A ductless head gives that level its own cooling on its own schedule, apart from the main thermostat upstairs. The outdoor unit goes on a bracket or pad above snow level, with the line set routed through the wall to keep it out of sight.

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. One head for a stubborn far bedroom is the low end, while a finished lower level and a walkout facing the wetlands each add a head. Compare central AC vs ductless costs.
Most homes buy electricity from Connexus Energy, which offers rebates on air-source, ductless and ground-source heat pumps and central air, plus a reduced-rate program for heat pumps paired with a furnace; the rest are on Xcel Energy, whose heat pump rebates run through its Trade Partner Network. Rebate programs change every year, so check the utility's current terms before you buy.

Often it can. When the room is hot because the old heat-sized ducts can't carry enough air, a head inside the room cools it directly. We look at the duct run first, because sometimes an added return does the job for less. If that one room is the only problem, a single-zone system is usually the cheaper route.
It often is. A finished walkout has its own load, with glass facing the water and a floor close to the ground, and a ductless head can handle it separately from upstairs. It cools and dries that level without running the whole-house system longer. We size the head to the room so it doesn't short-cycle, which is what leaves the air clammy.
