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 New Hope costs $4,500–$9,500 installed, with 80% AFUE models near $4,500–$6,000 and 96–98% condensing units near $6,500–$9,500. Every quote is written, flat-rate and based on a Manual J. Because many homes here return air through panned joists, we price any return work into the same quote.
The furnace in a New Hope split-entry usually sits in the lower level, half below grade, next to a water heater that shares its chimney. Moving to a 96% furnace means PVC out through the rim joist. The lower level's rim often sits only a foot or two above grade, so the terminations need a spot that stays above the snow and clear of window wells, and the water heater left behind in the chimney may call for a stainless liner or a power-vent model.
The bigger variable is the return. A new furnace with a variable-speed blower wants more return air than a 1960s panned joist system supplies, and a new furnace installed on the old return runs loud and hot. We seal the pans with mastic or add a real return duct, sometimes one for the lower level. CenterPoint Energy supplies the gas, and its furnace rebates let you use the dealer you choose. We pull the mechanical permit.

CenterPoint Energy is the gas utility in New Hope, and its rebates cover high-efficiency furnaces, boilers and thermostats; the application has to be filed in the same calendar year as the install. A Home Energy Squad visit, offered through CenterPoint, checks for air leaks and insulation gaps before new equipment is sized. On the electric side, Xcel Energy has rebates for central AC and heat pumps installed to its quality-installation standards, and some of those need an Xcel-registered contractor. Rebate programs change every year, so check the utility's current terms before you buy.

It suits this house type well. A split-entry needs full heat only on the coldest nights, and the rest of the time a two-stage furnace runs long, low cycles that keep the lower level from lagging so far behind the upstairs. Pair it with a variable-speed blower and a thermostat that runs the fan on low between calls, and the two levels stay closer together.
Rarely all of it. Supply trunks in houses of this age are usually sheet metal that can stay. The return side is where the work goes: sealing panned joist cavities, enlarging the return drop at the furnace, or adding a lower-level return. That work shows up as its own line in the quote, so you can see what it costs next to the furnace itself and decide.
