Central AC replacement in Minneapolis runs $5,200–$9,800 installed, with a matched coil and condenser sized by Manual J. Boiler homes with radiators usually go ductless, and a story-and-a-half's upstairs often needs its own head.
What an AC replacement involves in Minneapolis depends on how the house heats. Homes with a forced-air furnace, including most converted gravity systems, take a matched condenser and coil, but the coil has to fit a low basement, the returns often need work, and upper floors with no ducts still need a ductless head. Boiler homes have no ducts at all. The choices there are ductless heads or a high-velocity small-duct system, which national cost guides such as HomeGuide put at $3,500–$15,000+.
On a narrow lot, finding a condenser spot that meets the manufacturer's clearances takes some care, and the install needs the city's mechanical permit. Some older houses need panel work for the new circuit. Xcel Energy, the city's electric utility, offers Residential Cooling Rebates and Heat Pump Rebates; ask Xcel whether the rebate needs a registered contractor. CenterPoint Energy adds a ducted heat pump rebate when the heat pump is paired with a gas furnace.

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. For what drives a quote locally, see HVAC cost in Minneapolis.
Heat pump, AC and ductless rebates come from Xcel Energy, and some of those need an Xcel-registered contractor, so ask before you sign. Rebate programs change every year, so check the utility's current terms before you buy.

Wherever it keeps the manufacturer's clearances: open air above it, space on the sides for airflow and service, and distance from windows. Between houses a few feet apart, the alley side or the back of the house often works better than the gap between walls. We also keep it out from under roof drip lines and plan the line set into the basement before quoting.
Sometimes. A central air conditioner or heat pump needs its own circuit and an outdoor disconnect, and some older city houses still have small electrical service or a panel with no open spaces. If you're replacing an existing AC that already has its circuit, the wiring is usually reusable. For a first-time install or a larger heat pump, we look at the panel on the first visit and note in the quote if an electrician is needed.
