New central air in Carver runs $5,200–$9,800 installed, in a written quote, with rebates set by Xcel Energy or Minnesota Valley Electric. Your electric utility, Xcel Energy east of Jonathan Carver Parkway or Minnesota Valley Electric west of it, decides which AC and heat pump rebates apply.
In Carver's 2000s neighborhoods, an AC replacement is usually straightforward. The pad, line set and furnace are already in place, and the question is whether the old coil and copper can serve the new unit. Equipment built from 2025 on uses R-454B or R-32, so we match a new coil to the condenser and replace or flush the line set if it can't be reused. Walkout lots sometimes put the condenser a full story below the coil, which is fine within the manufacturer's line-set limits.
The historic homes near the river are where cooling takes more thought. Brick and stone walls and tight chases rarely allow full-size ducts, so ductless heads or a high-velocity small-duct system usually make more sense than forcing central air in.

What moves an AC quote within that range: tonnage from the Manual J load calculation, the SEER2 rating, a new coil and line set, and any electrical work. See the AC replacement cost guide or furnace and AC together.
Xcel Energy customers have heat pump and cooling rebates; ask whether the rebate needs a registered contractor. Minnesota Valley Electric Cooperative members have their own rebates, and the heat pump rebates generally require enrolling in an off-peak program and using a Quality Installation contractor. Rebate programs change every year, so check the utility's current terms before you buy.

In most cases, yes. A ductless mini-split puts a head on the wall in each area with a small hole for the line set, and it heats as well as cools. A high-velocity small-duct system runs flexible tubing through closets and the attic to small round outlets. Both avoid cutting large chases. We look at the attic, the basement and the rooms you want cooled, then quote the option that fits.
If the gas furnace is healthy, a heat pump in the AC's spot works as a dual-fuel system: it cools in summer and heats in milder weather, and the furnace covers the deep cold. Whether it pays depends on your electric rate and your utility's programs. We compare it against a straight AC in the same written quote.
