Furnace Replacement in Roseville, MN
A Roseville furnace replacement runs $4,500–$9,500 installed, with a written flat-rate quote sized by a Manual J. In a finished 1950s basement, a sealed-combustion 96–98% model also ends the furnace room's combustion-air problem.
Furnace replacements in Roseville homes
A 96–98% furnace often solves the finished-basement problem in a Roseville rambler, because it's sealed combustion: it takes its air from outside through PVC and no longer depends on the furnace room's door. The tricky part is getting two PVC pipes and a condensate drain out of a finished basement without tearing into ceilings, which usually means the shortest route to a rim joist and a termination that clears the snow and the nearest window. Once the furnace leaves the old chimney, the water heater in it needs a liner or a power-vent model.
Sizing deserves attention too. Many of these houses have added insulation and windows since the 1950s, and the furnaces that replaced the originals were often sized to match them rather than the house as it is now. A Manual J usually lands smaller. The city's mechanical permit comes with a furnace swap.

Furnace replacement in Roseville: questions
Our Roseville basement is finished. How does PVC venting get out without tearing up the ceiling?
We look for the shortest path from the furnace room to an outside wall, usually straight through the rim joist above the foundation. If the furnace room isn't on an outside wall, the pipes can run in a boxed soffit along an unfinished edge or through a closet. The condensate drain goes to a floor drain or a pump. The route is planned during the quote visit, so any patching is settled before the price is written.
Does Xcel's furnace rebate in Roseville need a particular contractor?
It can. Xcel Energy's heating equipment rebate page points homeowners to participating contractors, and Xcel's rebate sheet marks some measures as requiring an Xcel-registered contractor. We don't claim that status, so check the current rules for the furnace you're buying before you count on the rebate. The old federal 25C tax credit ended for equipment placed in service after December 31, 2025, so it's no longer part of the math.
