Central AC replacement in Bloomington costs $5,200–$9,800 installed with us, in writing before we start. On the east side that usually means pulling an R-22 condenser and coil from a 1950s or 60s rambler and deciding whether the old line set can stay.
On the east side, AC replacement usually means pulling an R-22 condenser from a 1950s or 60s rambler, along with the coil on the furnace, and deciding whether the old copper line set can stay. Lines that carried R-22 have to be flushed or replaced before they meet R-454B or R-32 equipment, and lines buried in a finished basement ceiling are often simpler to replace than to trust. These ramblers usually have more insulation and better windows than when their first AC went in, so the new unit often comes out smaller.
West-side split-levels and walkouts ask more of the equipment, and a two-stage or variable-speed system with zoning handles floors that heat and cool differently. Heat pumps fit either side of town, paired with the existing gas furnace so it covers the coldest weeks while the heat pump handles cooling and the shoulder seasons.

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.
Possibly, since Bloomington homes are typically CenterPoint gas and Xcel electric customers. CenterPoint Energy's ducted air-source heat pump rebate requires pairing with a gas furnace as a hybrid system. Xcel Energy's heat pump rebates require one of its Trade Partner Network contractors, and they can't exceed the installation cost. Check both programs before choosing equipment or an installer. Our heat pump installs run $7,500–$14,500.
Before the old condenser is disconnected, an EPA Section 608 certified technician recovers the refrigerant into a recovery cylinder, as federal rules require; venting it is illegal. Recovered R-22 can go to a reclaimer and back into service for the older systems still running. Because recovery is required on any replacement, the written quote should cover it along with the new coil and line-set work.
