In Hastings, new central air from us runs $5,200–$9,800 installed, sized by Manual J and priced in a written, flat-rate quote. In the older houses near West Second Street, the plan often adds returns, because ducts laid out for gravity heat rarely move enough air for cooling.
Most AC replacements in Hastings ramblers and newer homes are straightforward: a condenser and a matched coil on the existing furnace, with a check of the line set and the pad. The older houses near downtown take more planning. Converted gravity ducts can carry cooling air once the joints are sealed and a return or two is added, and the coil has to fit a furnace that may sit in a low old coal-room corner. Where the house heats with radiators, ductless heads or a small-duct high-velocity system stand in for central ducts.
Condensers on narrow older lots need the manufacturer's clearances and a spot away from bedroom windows. Most of Hastings buys electricity from Xcel Energy, which runs its own cooling rebates, while some rural-edge addresses are on Dakota Electric. Homes on CenterPoint gas can also look at dual fuel, a heat pump working alongside the furnace, priced next to a straight AC.

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's rebates cover central AC, heat pumps and ductless mini-splits; ask whether the rebate needs a registered contractor. Addresses on the rural edges served by Dakota Electric Association have its Energy Wise Rebates instead, including heat pump rebates and a central AC tune-up rebate. Rebate programs change every year, so check the utility's current terms before you buy.

Usually, yes. The coil on the furnace and the condenser outside are rated as a matched pair, and a new condenser built from 2025 on uses R-454B or R-32, which older coils weren't built for. Some 2000s systems also still run R-22. We match the coil to the new condenser, check the line set and pad, and the quote says what stays.
Without ducts, the choices are ductless heads or a small-duct high-velocity system. Ductless heads suit a few rooms and mount on a wall, while high-velocity runs thin ducts through walls and ceilings to every room. A Manual J for each room shows what each option needs, and we quote them side by side. Window units remain the stopgap.
