How Long Does a Furnace Replacement Take?
A straight furnace swap is usually done in one day. Venting changes, a chimney liner, gas line or duct work, and the permit inspection add time. What to expect.

Furnace replacement in Dayton runs $4,500–$9,500 installed with us. An 80% model is roughly $4,500–$6,000, and a 96–98% condensing one roughly $6,500–$9,500. CenterPoint Energy, the city's gas utility, has its own furnace rebates. The written, flat-rate quote follows a Manual J, not the old nameplate.
Replacements in Dayton mostly land in the 1970s-era houses, since the newer ones aren't due yet. Taking one of those from a chimney-vented 80% furnace to 96–98% involves an intake and an exhaust pipe in PVC through the rim joist, a drain for the condensate, and a new venting plan for the water heater still in the old flue. Nameplate-for-nameplate swaps over the decades often carried an oversized furnace forward, and a room-by-room Manual J for the house in its present condition tends to call for less.
On rural lots burning propane, a high-efficiency furnace pays back faster, because a unit of heat from propane usually costs more than one from natural gas, and the quote includes the propane conversion. CenterPoint's heating rebates let you pick the dealer, provided the application goes in the same year the furnace does. The mechanical permit and inspection are part of our job.

An installed furnace from us runs about $4,500–$9,500 in Dayton: 80% AFUE roughly $4,500–$6,000, 96–98% AFUE roughly $6,500–$9,500. Same prices in Dayton as in every town we serve. See the furnace replacement cost guide.
CenterPoint Energy handles furnace and boiler rebates here and lets you pick any dealer. For anything electric, start with the name on your bill. Connexus Energy lists rebates on ground-source, air-source and ductless heat pumps and a lower dual-fuel rate for heat pump homes. Elk River Municipal Utilities pays bill credits on ENERGY STAR air conditioners, heat pumps and furnaces with ECM blowers, and Anoka Municipal Utility pays toward matched high-efficiency central AC; both want the AHRI certificate. For Xcel customers, ask whether a heat pump rebate requires a registered contractor. Rebate programs change every year, so check the utility's current terms before you buy.

Three pieces of work beyond the furnace itself. Two PVC pipes, intake and exhaust, leave through the rim joist or a side wall, with terminations kept clear of windows, the gas meter and drift height. A condensate line carries water to a floor drain, or to a pump if the drain is far away. And the water heater, left by itself in the chimney, needs a liner or a replacement with its own power vent.
There can be. Elk River Municipal Utilities lists a rebate for an ENERGY STAR replacement furnace with an ECM blower motor, paid as a credit on your electric bill, since the blower runs on its power. It wants the AHRI certificate and an itemized invoice. That's separate from CenterPoint Energy's rebate on the gas side, and each utility sets its own rules, so check both before you buy.
