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.

Victoria's three-level homes over 3,000 square feet are where a room-by-room Manual J earns its keep; the answer may be zoning or a second system instead of a bigger furnace. Replacement runs $4,500–$9,500 installed with us, quoted flat-rate in writing.
Victoria's newer homes are big, open and often on their first furnace replacement, and copying the builder's nameplate is how you end up with the same comfort problems. A Manual J on a three-level house with a two-story great room and a finished walkout often points to a two-stage or modulating furnace with a variable-speed blower, sometimes with zoning, and occasionally to a second system for a large lower level. Static pressure gets measured too, since undersized returns are common and a new blower can't fix them.
Venting is usually PVC already; we check pipe size, length and termination clearances against the new furnace's manual. On older cabins and ramblers by the lakes, a move from 80% to condensing means new venting and a look at the water heater's chimney. Gas comes from CenterPoint Energy, whose heating system rebates let you use the dealer of your choice, provided the application is filed in the same calendar year as the install.

An installed furnace from us runs about $4,500–$9,500 in Victoria: 80% AFUE roughly $4,500–$6,000, 96–98% AFUE roughly $6,500–$9,500. Same prices in Victoria as in every town we serve. See the furnace replacement cost guide.
Victoria's gas utility is CenterPoint Energy, whose heating rebates cover high-efficiency furnaces, boilers and thermostats with the dealer of your choice, plus a ducted heat pump rebate when the heat pump is paired with a gas furnace. Electric rebates depend on your address. Xcel Energy customers have Xcel's heat pump and cooling rebates, and Minnesota Valley Electric Cooperative members have MVEC's, which generally require off-peak program enrollment and a Quality Installation contractor. Ask whether the rebate needs a registered contractor before you buy. Rebate programs change every year, so check the utility's current terms before you buy.

It's often the best fit. A modulating furnace adjusts its fire in small steps, so on the many winter days that need only part of its capacity it runs long, quiet cycles instead of short blasts. In a three-level house with a two-story great room, that steadier airflow evens out the floors and cuts blower noise. It costs more than two-stage and pushes the price toward the upper end of our $6,500–$9,500 range for 96–98% furnaces.
Yes. Many tightly built newer homes here have an HRV or ERV tied into the furnace ductwork, and it has to be reconnected and rebalanced with the new blower. We check its connections, look at its core and filters, and confirm its controls still work with the new furnace. Skipping that step can leave the house stuffy or pull the ductwork out of balance.
