Furnace Replacement in Northfield, MN
Northfield furnace replacements land at $4,500–$9,500 installed with us: 80% AFUE around $4,500–$6,000, 96–98% around $6,500–$9,500. In Victorian and early-1900s houses, leaving the tall chimney usually means a liner or a power-vent water heater.
Furnace replacements in Northfield homes
Replacing a furnace in one of Northfield's Victorian or early-1900s houses starts with the venting. A 96% furnace leaves the tall masonry chimney for PVC through a side wall, and the water heater stays behind in a flue far too large for it, so a liner or a power-vent water heater usually follows. Some owners keep an 80% furnace when a side-wall route would cross a porch or the front of the house, and we price both.
Sizing is the other trap. A foursquare that has had insulation blown into its walls and new windows needs far less furnace than the one installed when it was drafty, and gravity-era ducts can carry plenty of air at low speed. A Manual J settles it. In converted apartment houses each unit usually has its own furnace, and they can be replaced over a few seasons. Inside city limits the mechanical permit comes from the City of Northfield, on either side of the Rice–Dakota county line.

What affects the price of a new furnace in Northfield?
What moves the quote in Northfield: venting changes on a switch to a condensing furnace, a liner for a water heater left alone in the chimney, and ductwork and returns. See the furnace replacement cost guide.
Are there rebates for a new furnace in Northfield?
CenterPoint's programs don't apply here. Ask us which rebates apply when we quote. Rebate programs change every year, so check the utility's current terms before you buy.

Furnace replacement in Northfield: questions
Our Northfield Victorian has a porch across the front. Where can a 96% furnace vent?
Probably not the front wall. The pipes need clearance from windows, doors and the gas meter, so we look at a side or rear wall, or a roof termination if the furnace is far from any usable wall. If no route works, keeping an 80% furnace on a lined chimney is the fallback. We price the options and write them into the quote.
Can we replace just one furnace in our Northfield apartment house?
Yes. Each furnace in a converted house is its own system, and replacing them one at a time spreads out the cost. The catch is shared venting: if two furnaces use one chimney and one switches to PVC, the remaining furnace and any water heater still need a flue that drafts properly. Any liner work goes in the quote.
