Furnace Replacement in Saint Paul, MN
A Saint Paul furnace replacement runs $4,500–$9,500 installed, flat-rate and written, in a city where most houses predate 1950. The quote is written and flat-rate, sized by a Manual J load calculation, and it lists the Department of Safety and Inspections permit the city requires.
Furnace replacements in Saint Paul homes
Venting drives most Saint Paul furnace quotes. A 96–98% furnace exhausts through PVC out a side wall, and on narrow city lots the termination has to clear windows, doors and the gas meter by the distances in the manufacturer's instructions, often with the next house only a few feet away. When the old 80% furnace leaves the brick chimney, the water heater is left alone in a flue sized for two appliances, and it usually needs a liner or a power-vent replacement. Sizing matters as much. Houses that began on gravity heat often carry furnaces far bigger than the load, and a Manual J on a 1920s bungalow with newer windows and attic insulation regularly comes out smaller.
Xcel Energy supplies both gas and electricity here, so ask whether its furnace rebate needs a registered contractor before you choose a model.

What affects the price of a new furnace in Saint Paul?
By efficiency: 80% AFUE roughly $4,500–$6,000; 96–98% AFUE roughly $6,500–$9,500. See the furnace replacement cost guide. For what drives a quote locally, see HVAC cost in Saint Paul.
Are there rebates for a new furnace in Saint Paul?
In Saint Paul, Xcel Energy is both the gas and the electric utility, and its rebate list includes gas boilers as well as furnaces, which matters in a city with this many radiator systems. Condensing boilers are where boiler rebates usually apply; steam boilers may not reach the required efficiency, so ask before counting on one. Rebate programs change every year, so check the utility's current terms before you buy.

Furnace replacement in Saint Paul: questions
Our Saint Paul house heats with hot-water radiators. Should we switch to a furnace when the boiler goes?
Usually not. Running supply and return ducts through plaster walls in a 1910s house is slow, messy and expensive, and radiators give quiet, even heat. A failing hot-water boiler can go to a modulating condensing boiler sized to the radiators; a steam system needs a new steam boiler. For cooling, ductless heads or a small-duct high-velocity system avoid the ductwork problem. A furnace makes more sense for an addition or a house that already has partial ducts.
Why does asbestos come up when we replace an old furnace in Saint Paul?
Houses built before 1950 often have asbestos in the heating system: paper tape on duct seams, insulation on an old gravity furnace or its plenum, and wrap on boiler piping. Left intact it is usually stable, but a furnace swap means cutting and moving those pieces. Suspect material has to be tested first, and if it contains asbestos, a licensed abatement contractor removes or encapsulates it before we start. We point it out when we quote.
