2-Stage vs Variable-Speed AC: Which Fits a Minnesota Home?

A new central air system in Becker costs $5,200–$9,800 installed with us, including a coil matched to the R-454B or R-32 outdoor unit. Early-1990s R-22 line sets hold mineral oil, so they get flushed or replaced.
Many Becker AC replacements are the first the house has had. An early-1990s condenser that has run on R-22 for three decades comes out with its indoor coil, and the line set gets a close look. Lines that carried R-22 hold mineral oil and must be flushed or replaced for new refrigerant, and some older line sets are undersized for current equipment. Most Becker houses have a straight run from the basement to a pad beside the house, which keeps that part simple.
Xcel Energy serves electricity in the city, and its programs include cooling rebates, heat pump rebates through the Trade Partner Network, and AC Rewards for smart thermostats. A heat pump is worth pricing when the furnace still has years left, since it cools in summer and trims the gas bill in spring and fall. A Manual J often trims tonnage too, in houses re-sided or re-windowed since the builder's install.

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.
AC Rewards is Xcel Energy's smart-thermostat program: you enroll a qualifying thermostat, Xcel can adjust it during peak demand, and you receive an annual reward. Xcel's rebate list also covers smart thermostats enrolled in the program. It doesn't change which air conditioner you buy, but putting in a compatible thermostat with the new system makes enrolling easy. Check Xcel's current terms, since rewards and eligibility change.
Often, yes. Builders in the 1990s sized air conditioners with a rule of thumb, and new windows, siding wrap and attic insulation have cut the cooling load since. We run a Manual J on the house as it stands now instead of copying the old nameplate. A right-sized or two-stage system runs longer cycles and pulls more moisture from the air, while an oversized one cools fast and leaves the house clammy.
