A new central AC in Roseville runs $5,200–$9,800 installed. Many retrofit systems here were mismatched to the furnace coil, so the new condenser comes with a coil built to match it.
A new AC in a Roseville rambler is a chance to fix what the first retrofit got wrong. The coil gets matched to the condenser and its refrigerant, the plenum transition is built properly instead of forced, and the return side gets measured, because a 1950s house with one or two small returns can't feed a new system its rated airflow. Adding a return or a larger filter grille is often part of the quote.
The condenser usually goes back beside the house on a new pad, clear of bedroom windows and the dryer vent. Lake houses and rebuilds around Lake McCarrons and Lake Owasso sometimes have rooms with no ducts, where a ductless head is the answer. Gas and electricity both come from Xcel Energy here. Swapping the AC for a heat pump would add spring and fall heating, with the gas furnace covering real cold. Replacements normally need a mechanical permit from the city.

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 Roseville.
For the dual-fuel setups that suit many Roseville ramblers, Xcel lists rebates for standard and cold-climate air-source heat pumps and a bonus when insulation work comes before the heat pump. Its heat pump rebates are paid through Trade Partner Network contractors, so ask about that before you sign. Rebate programs change every year, so check the utility's current terms before you buy.

It will once the returns are checked. A new air conditioner needs a certain airflow across its coil, and many 1950s Roseville houses have one or two small returns that can't supply it. The result is a frozen coil, weak cooling and a compressor working too hard. Static pressure gets measured during the quote. If the return is short, we add a return run or a larger filter grille, and that cost goes in the written quote.
Usually with a ductless head for that part of the house. Extending ducts into rooms that were never designed for them, like a converted porch or an upper-level room over a crawlspace, is often impractical. A single-zone ductless heat pump cools that space on its own thermostat and can heat it in spring and fall. The central AC then serves the rest of the house at the size its ducts can actually carry.
