Furnace replacement calls in West St. Paul homes

Venting decides most West St. Paul furnace quotes. In a 1950s house the old furnace shares a masonry chimney with the water heater; a 96–98% furnace leaves that chimney for two PVC pipes through the rim joist, and the water heater then needs its own vent solution, a stainless liner or a power-vent unit, which we price in the same quote. If the side-wall exit would land near a window, a walkway or the gas meter, we look at another wall or a roof exit.

About 40 percent of the city's housing is rented, and landlords sometimes choose an 80% furnace to keep using the chimney; it costs less up front and more in gas every winter after. Owners planning to stay usually come out ahead with a condensing furnace. Xcel's Heating Equipment Rebates apply to high-efficiency gas furnaces, with a participating-contractor rule worth checking before you sign. We pull the city's mechanical permit.

Are there rebates for a new furnace in West St. Paul?

Xcel Energy is the only gas and electric utility in West St. Paul, per the city, so a single company's rules apply. Its Heating Equipment Rebates cover high-efficiency gas furnaces, and the program page points you to a participating contractor, so confirm the terms for your model first. Heat pump rebates are paid through Xcel's Trade Partner Network, and the cooling side includes Residential Cooling Rebates, Saver's Switch and AC Rewards for smart thermostats. Minnesota's federally funded home energy rebates have not launched. Rebate programs change every year, so check the utility's current terms before you buy.

Furnace replacement in West St. Paul: questions

Is an 80% furnace a reasonable choice for our West St. Paul rental house?

Sometimes. An 80% furnace costs about $4,500–$6,000 installed with us, against about $6,500–$9,500 for a 96–98% model, and it can keep venting into the existing chimney. The tradeoff is fuel: an 80% furnace sends about 20 cents of every gas dollar up the flue, a 96% model about 4. If the tenant pays for gas, weigh that against rent and turnover; if you pay it, the condensing furnace usually wins.

We're remodeling our West St. Paul house. Should the furnace be replaced before or after?

After the plan is set, and ideally before the drywall goes up. New windows, insulation or an addition change the heat loss, so the Manual J should describe the finished house rather than today's. Ducts to new rooms, and any return the remodel covers, are far easier to run with the walls open. If the old furnace fails mid-project, we size the replacement for the house as it will be.
