How Long Does a Furnace Replacement Take?

A furnace replacement in Arden Hills costs $4,500–$9,500 installed with us, written, flat-rate and sized with a Manual J. With about half the houses built before 1974, venting is the first question, and Arden Manor's manufactured homes need a direct-vent furnace approved for them.
Most Arden Hills replacements happen in 1970s houses, and venting comes first. Going from an 80% furnace in the original flue to a 96–98% condensing furnace means two PVC pipes out through the rim joist, a condensate drain to a floor drain or pump, and a new plan for the water heater that shared the flue: a vent resized for it alone, a liner, or a power-vent model. A Manual J on a house with newer windows and added attic insulation often calls for less capacity than the furnace it replaces.
Arden Manor is its own category. A manufactured home needs a direct-vent furnace built for manufactured housing, usually downflow, sized to the closet and the floor ducts, with the vent through a roof jack listed for that furnace.

By efficiency: 80% AFUE roughly $4,500–$6,000; 96–98% AFUE roughly $6,500–$9,500. See the furnace replacement cost guide.
Xcel's Minnesota programs are the ones to check: heating equipment rebates for high-efficiency gas furnaces, Residential Cooling Rebates for central air, and heat pump rebates tied to contractors in its Trade Partner Network. Rebate programs change every year, so check the utility's current terms before you buy.

Often, yes. If the existing cooling coil fits the new furnace cabinet and the blower can be set for it, the old R-22 system keeps working. The catch comes later: when the AC fails, its coil must be replaced to match the new refrigerant, and that can mean reworking the plenum on a furnace that's only a few years old. If the AC is near 20 years old, replacing both together is usually the better spend.
Usually. The federal manufactured-home code treats the combustion air inlet and flue outlet as parts of the furnace, listed along with it, so the vent kit or roof jack has to be the one approved for the new model, not whatever the old furnace used. We check the roof penetration and flashing during the quote, and the new vent, the roof work and the permit are all on the written price.
