96% vs 98% AFUE Furnace: Is the Upgrade Worth It in Minnesota?
What AFUE measures, the gas math from 80% to 96% to 98% using your own bill, and what a 98% furnace really buys you in a cold Minnesota house.

Edina homeowners replacing a furnace pay $4,500–$9,500 installed with us, depending mostly on 80% versus 96–98% AFUE and on venting. Every quote is written, flat-rate and sized by Manual J. In Edina's 1920s and 30s houses, the tricky part is often routing the PVC vent on a tight lot.
Most Edina replacements happen in one of two settings. In the Country Club District and Morningside, going from an 80% furnace to a 96% model means PVC intake and exhaust through a rim joist that may be a few feet from the lot line, and the terminations have to clear windows, doors and the gas meter. Where a side-wall route won't work, some manufacturers allow the PVC to run up an unused chimney, and otherwise an 80% furnace is the sensible choice. Once the furnace leaves the chimney, the water heater usually needs a liner or a power-vent model.
Rebuilt homes with two furnaces get a separate load calculation for each. CenterPoint Energy supplies gas across Edina; its heating rebates cover qualifying high-efficiency furnaces with the dealer of your choice, and it runs a separate smart thermostat rebate. We handle the city mechanical permit and inspection.

An installed furnace from us runs about $4,500–$9,500 in Edina: 80% AFUE roughly $4,500–$6,000, 96–98% AFUE roughly $6,500–$9,500. Same prices in Edina as in every town we serve. See the furnace replacement cost guide. For what drives a quote locally, see HVAC cost in Edina.
Edina homes buy gas from CenterPoint Energy and electricity from Xcel Energy. CenterPoint's heating rebates cover high-efficiency boilers as well as furnaces, useful for older houses that still heat with hot water, and you can use the dealer of your choice. Xcel's heat pump rebates, including cold-climate mini-splits for upstairs rooms without ducts, work through its Trade Partner Network, so ask whether the rebate needs a registered contractor. Minnesota's HEAR and HOMES rebates haven't launched. Rebate programs change every year, so check the utility's current terms before you buy.

Almost always. Modern furnaces are much smaller than the old gravity and early forced-air units, and an upflow model fits through a standard basement door and down a turning stair. Headroom is the tighter limit: a condensing furnace plus the AC coil on top can stand taller than the old setup, so in a low basement we measure to the joists and choose a shorter cabinet or coil to fit.
Sometimes the humidifier body can be remounted, but usually we replace it with the furnace, since the old pad, valve and saddle tap are worn and the new duct connections rarely line up. Plaster-wall Edina houses do well with one in winter, set to follow the outdoor temperature so indoor humidity stays around 25 to 35 percent, lower in deep cold, which keeps frost off the windows.
