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-splits in North Oaks cost about $4,200–$12,500 installed, written flat-rate, depending on heads and line length. On big lots they serve additions, lake-side rooms and spaces far from the furnace.
In a house this large, some rooms sit a long way from the nearest furnace. A guest suite over a garage, a sunroom added to a 1950s house near the golf course, or a lower-level room in an East Oaks home can sit at the end of the longest duct run in the building, and a ductless head serves them without lengthening it. Line sets are also longer on big lots, so we check the length and rise against the manufacturer's limits before quoting.
Trees are the other local factor. North Oaks has wooded lots, so the outdoor unit needs space from brush and a route clear of falling debris. We often set it on a stand that keeps the coil above leaf litter.

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. Guest suites over garages, lake-side sunrooms and far-flung East Oaks lower-level rooms each need a head and long line set. Compare central AC vs ductless costs.
Xcel's furnace rebates reward high-efficiency gas models, for its heat pump rebates, ask whether the rebate needs a registered contractor. Rebate programs change every year, so check the utility's current terms before you buy.

Every manufacturer publishes a maximum line-set length and a maximum rise between the indoor and outdoor units. We measure the route before we quote and pick equipment that fits within those limits. If the best location for the outdoor unit is too far away, we move it or use a different system.
Yes, with some care. Leaves, seeds and brush can pack the outdoor coil and block airflow, so we leave clearance around the unit and mount it off the ground when the site calls for it. Keep plants trimmed back and rinse the coil gently each year, or have it done at a maintenance visit.
