Furnace Replacement in St. Francis, MN
A replacement furnace from us costs $4,500–$9,500 installed, about $4,500–$6,000 for 80% AFUE and $6,500–$9,500 for 96–98% condensing. In St. Francis, where many furnaces date from the 1990s, we size the new one with a Manual J and quote it flat-rate in writing.
Furnace replacement calls in St. Francis homes
Replacing a builder's furnace in a St. Francis subdivision home is usually a condensing-to-condensing swap, but never a copy. Many builders picked the original size by square footage; a room-by-room Manual J of the house today, with its current windows and insulation, often comes out smaller, which means longer, quieter cycles. The old PVC gets checked against the new furnace's venting tables and replaced if it's the wrong size or too long, and the condensate route gets a new trap, plus a neutralizer where needed.
Gas here comes from CenterPoint Energy, whose heating rebate accepts any dealer's install; file it in the same year the furnace goes in, with the final invoice rather than the proposal. If you're adding a heat pump, pairing it with the new gas furnace also opens CenterPoint's ducted heat pump rebate. We handle the permit and the inspection.

How much does a new furnace cost in St. Francis?
An installed furnace from us runs about $4,500–$9,500 in St. Francis: 80% AFUE roughly $4,500–$6,000, 96–98% AFUE roughly $6,500–$9,500. Same prices in St. Francis as in every town we serve. See the furnace replacement cost guide.
Are there rebates for a new furnace in St. Francis?
St. Francis pairs CenterPoint Energy gas with Connexus Energy electricity, which opens programs on both sides. CenterPoint's furnace and boiler rebates work with any installer if you file within the install year, and a ducted heat pump qualifies only with a gas furnace as its backup. Connexus rebates heat pumps and central air, and it bills heat pump heating at a reduced rate when an automatic furnace stands behind it. Don't plan around Minnesota's HEAR or HOMES rebates; neither has launched. Rebate programs change every year, so check the utility's current terms before you buy.

Furnace replacement in St. Francis: questions
Will the old PVC vent pipes work with a new furnace in our St. Francis house?
Sometimes. The pipe has to match the new furnace's diameter and maximum length in its venting tables, slope back toward the furnace correctly and be in good shape, and the terminations have to meet today's clearances. Older installs sometimes skipped primer or used the wrong fittings. If the old run passes, reusing it saves some labor; if not, we replace it and put the cost in the written quote.
We're replacing the furnace in St. Francis. Should the AC be replaced at the same time?
If the air conditioner is 15 or more years old, or still on R-22, doing both together usually makes sense. The new furnace's blower and the coil on top of it should match the outdoor unit, and one installation means one round of labor and a single matched system. If the AC is newer, we keep it and set the furnace's blower to match it. Either way, the quote spells it out.
