How Long Does a Furnace Replacement Take?
Most furnace replacements take one day; venting, a chimney liner, gas line or duct work can add a second. Ours run $4,500–$9,500 installed. Call 612-429-3465.

Replacing a furnace on Savage's CenterPoint gas runs $4,500–$9,500 installed, mostly in homes built from about 1990 to 2010. The quote comes in writing, flat-rate, with Manual J sizing, and a finished basement's condensate route gets planned before we order.
Most Savage homes built during the boom already have a condensing furnace, so a replacement is largely about fit and routing. The new furnace's manual decides whether the old PVC pipe size and length can stay. With a finished basement, the condensate route gets a fresh look: a gravity drain to a floor drain is better than a pump when the layout allows, and when a pump is needed, it should have an overflow switch wired to shut the system down.
Townhome associations often have a say in anything that changes the outside of the building, including a new PVC termination location, so reusing the existing wall penetration keeps things simple. On hillside lots, a termination that keeps getting buried can move with the new furnace. Xcel Energy or Minnesota Valley Electric Cooperative supplies the electricity depending on the address, which only matters if you add a heat pump alongside the furnace. A new PVC termination or furnace swap normally needs a Savage mechanical permit, listed on your written quote.

By efficiency: 80% AFUE roughly $4,500–$6,000; 96–98% AFUE roughly $6,500–$9,500. See the furnace replacement cost guide.
Sometimes. If a floor drain, laundry standpipe or sump is within reach and lower than the furnace's drain outlet, the condensate can run there by gravity. Where the basement is finished, that often means a short run inside a wall or soffit. When the drain is across the room or behind finished space, a pump is still the practical answer, and we install it with a safety switch that shuts the furnace off before it overflows.
It can. CenterPoint Energy's ducted air-source heat pump rebate applies only when the heat pump is paired with a gas furnace as a dual-fuel system, which is exactly this setup. The electric side is separate: Xcel Energy or Minnesota Valley Electric Cooperative may have their own heat pump programs, and some utility rebates require a registered contractor. Check both utilities' current rules before you sign.
