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.

A furnace replacement in Golden Valley costs $4,500–$9,500 installed with us, sized room by room with a Manual J, which matters in houses with walls of glass. The quote is written and flat-rate, and it lists the venting, permit and any water heater liner the job needs.
Golden Valley replacements divide by house type. In the 1940s–60s ramblers and split-levels, the furnace often sits beside a chimney in the middle of the basement. Going to a 96% furnace means a PVC run to a side wall, a condensate drain or pump, and a liner or power-vent solution for the water heater left alone in the chimney. Additions at the end of the ductwork are worth fixing at the same time, since a new furnace can't push air through a duct that isn't there.
The mid-century modern houses near Sweeney Lake and in Tyrol Hills need more thought. Big glass walls change the heat loss, so the Manual J counts every window by size and direction. Where the heat runs through ducts in the slab, the replacement is usually a downflow furnace feeding those ducts, and we inspect them before quoting. CenterPoint Energy supplies the gas; its heating rebates cover qualifying high-efficiency furnaces, and a proposal alone doesn't count as proof of purchase.

Golden Valley homes are on CenterPoint Energy gas and Xcel Energy electricity. For a mid-century house going ductless, Xcel's heat pump rebates list mini-splits and cold-climate mini-splits, and they run through its Trade Partner Network, so ask whether the rebate needs a registered contractor. CenterPoint's heating rebates cover high-efficiency boilers as well as furnaces, which matters for houses with radiant or hot-water heat, and you can use the dealer of your choice. Rebate programs change every year, so check the utility's current terms before you buy.

Usually very little. The swap happens in the furnace room: the old unit comes out, the new one goes in, and the ducts, gas and power reconnect. The PVC route from a 96% furnace to an outside wall is the part that can cross a finished ceiling, so we look for a path through the utility room, a soffit or a closet first. If a ceiling section must open, the quote says so.
Often, if the AC is due too. A heat pump replaces the AC, heats the house in milder weather, and hands off to the gas furnace in deep cold. CenterPoint Energy lists a ducted heat pump rebate only for systems paired with a gas furnace, which is exactly this setup, and Xcel Energy runs its own heat pump rebates through its Trade Partner Network. We price the furnace alone and the dual-fuel pair side by side.
