A Scandia furnace replacement, gas or propane, runs $4,500–$9,500 installed. We size it with a Manual J, the quote comes flat-rate and in writing, and where there's no gas main we set the furnace up for propane.
Fuel decides most Scandia furnace replacements. On a road with Xcel Energy gas, a 96–98% furnace is the usual pick; homes around 182nd and 188th streets buy gas from Minnesota Energy Resources. On propane, a condensing furnace's efficiency is worth even more, because propane heat typically costs more than natural gas heat, and a heat pump beside it cuts the gallons further.
Venting gets planned on the first visit. The PVC leaves out a side wall or up through the roof, clear of drifts, windows and the gas regulator, and in a 1970s house the water heater stranded in the old chimney usually needs a liner or its own vent. In an old farmhouse the floor drain can sit far from the furnace, so a condensate pump carries the water. Every replacement is sized with a Manual J load calculation, and the written quote lists the city's mechanical permit where one is required.

By efficiency: 80% AFUE roughly $4,500–$6,000; 96–98% AFUE roughly $6,500–$9,500. See the furnace replacement cost guide.
Probably Minnesota Energy Resources'. The city lists that utility for a small area around 182nd and 188th streets, while homes on the gas main elsewhere in Scandia buy gas from Xcel Energy; many Scandia homes have no gas main and burn propane, so check your gas bill to be sure. Minnesota Energy Resources rebates high-efficiency gas furnaces and boilers in existing homes, but not in houses built within the past two years. Amounts change every year, so read the utility's current terms before you buy.
Often, yes. A two-stage or modulating furnace runs on its low setting through most of the winter, which evens out temperatures in a rambler or split-level and cuts the short cycles that waste fuel. Propane usually costs more than natural gas for the same heat, so those savings count for more out here. Pair it with a variable-speed blower, and add a heat pump for spring and fall if you want to buy even less propane.
