Central AC replacement in Eagan costs $5,200–$9,800 installed with us, flat-rate after a Manual J load calculation, with a matched coil. The written flat-rate quote comes after a Manual J load calculation and includes a matched coil. Northern Eagan addresses on Xcel and the rest on Dakota Electric fall under different cooling rebate rules.
An Eagan AC swap usually lands on a 1980s or 1990s house whose first or second system is done. If the outgoing condenser runs R-22, the indoor coil comes out with it and the line set gets a close look, since new equipment built from 2025 on runs R-454B or R-32.
The electric utility shapes the rebate side. Most of Eagan is on Dakota Electric Association, which lists central AC and air-source heat pump rebates tied to a quality installation by a registered contractor who files the application. Northern Eagan addresses on Xcel Energy fall under Xcel's cooling rebates and AC Rewards program instead. If the furnace is also aging, a heat pump quote belongs next to the AC quote, since Dakota Electric also lists a first-time dual-fuel enrollment.

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 Eagan.
Dakota Electric's Energy Wise Rebates cover heat pumps, ductless systems and AC tune-ups, and its quality-installation rebates need a registered contractor; Xcel customers use Xcel's programs. Rebate programs change every year, so check the utility's current terms before you buy.

It helps, but it isn't a cure by itself. A variable-speed or two-stage system runs longer at low capacity, which mixes the air between floors and pulls more humidity. The upstairs still needs enough supply and a return path to get warm air back to the unit. We look at both before quoting, and sometimes a return added upstairs does more for the bedrooms than stepping up to the most expensive condenser.
Usually, and associations often prefer it. The new unit may have a different footprint, so we check the manufacturer's clearance on each side and above, and whether a neighbor's condenser will blow hot air straight into it. If the pad is sunk or cracked, a new level pad goes in. Check your association's approval process early, since some want the model and location in writing before work starts.
