Furnace Replacement in St. Louis Park, MN
A St. Louis Park furnace replacement costs $4,500–$9,500 installed, sized by a Manual J. The written flat-rate quote spells out the venting on a narrow lot.
Furnace replacements in St. Louis Park homes
Replacing a furnace in St. Louis Park comes down to venting more than anything else. Moving from an 80% to a 96–98% condensing furnace means intake and exhaust pipes through the rim joist, and on narrow lots the obvious wall is often too close to the neighbor's windows, the gas meter or a walkway. The fallback is a roof penetration or a longer run to the back wall, which we plan before quoting so the price holds.
The water heater usually shared that chimney. Once the furnace leaves, the water heater's small, cool exhaust sits alone in a flue sized for two and can condense and draft poorly, so we price a liner or a power-vent water heater in the same quote. Low basements also limit cabinet height once an AC coil sits on top. Gas here is CenterPoint Energy.

Furnace replacement in St. Louis Park: questions
Is an 80% furnace still a reasonable choice in St. Louis Park?
Sometimes. If no side wall or roof route works for PVC on a tight lot, or you're selling within a couple of years, an 80% furnace on a properly lined chimney is a legitimate choice, at roughly $4,500–$6,000 installed with us. For most owners staying put, a 96–98% furnace at roughly $6,500–$9,500 costs less to run over a Minnesota winter. We quote both when both fit.
Does a St. Louis Park story-and-a-half need a smaller furnace than it has now?
Often. Many of these houses carry a furnace sized long ago for a leakier house, before new windows and attic insulation went in. A Manual J load calculation works out the heat loss room by room, and the answer is frequently below the old nameplate. A right-sized furnace runs longer, quieter cycles. It won't fix an unducted upstairs, though; those rooms need their own solution.
