Furnace Replacement in South St. Paul, MN
Furnace replacement in South St. Paul costs $4,500–$9,500 installed, written and flat-rate after a Manual J. An 80% model runs about $4,500–$6,000 and a 96–98% condensing one $6,500–$9,500.
Furnace replacements in South St. Paul homes
A South St. Paul house built before 1960 has often been re-sided, re-windowed or insulated since, so the furnace it has now may have been sized for a leakier house. A Manual J based on the house today often lands smaller, which lets a condensing furnace run long, even cycles. Moving to 96–98% means PVC out through the band joist and a new vent arrangement for the water heater that stays in the chimney, both priced up front.
Your gas company decides the rebate route. The city lists both Xcel Energy and CenterPoint Energy as gas suppliers, so check your bill. If you're replacing before listing the house, schedule the work ahead of the time-of-sale evaluation so the report reflects the new furnace. Expect a mechanical permit from the city on a replacement.

What affects the price of a new furnace in South St. Paul?
What moves the quote in South St. Paul: venting changes on a switch to a condensing furnace, a liner for a water heater left alone in the chimney, and ductwork and returns. See the furnace replacement cost guide.
Are there rebates for a new furnace in South St. Paul?
Every South St. Paul address buys electricity from Xcel Energy, so check your gas bill to see which gas company's furnace rules apply. CenterPoint's heating rebates work with any dealer, as long as the application goes in during the calendar year of the install. Xcel's furnace rebates point you to a participating contractor, and heat pump rebates from Xcel go through its Trade Partner Network. Rebate programs change every year, so check the utility's current terms before you buy.

Furnace replacement in South St. Paul: questions
Should we replace the furnace before we list our South St. Paul house?
Only if it needs it. If the furnace runs safely and passes the time-of-sale evaluation, a buyer can plan its replacement. If it's near the end, with a cracked combustion chamber or a missing or visibly defective safety control, the evaluator marks it Hazardous, and hazardous items must be fixed before the buyer takes possession. Having it checked before the evaluation tells you which case you're in.
Our South St. Paul house has a boiler. Could we switch to a furnace?
You could, but it means running ductwork to every room of a house that was never built for it, which gets expensive and disruptive in finished walls. Many boiler owners keep hot-water heat and replace the boiler when it fails; national cost guides such as HomeGuide put gas boiler replacement at $4,000–$9,000. For cooling, ductless heads or a high-velocity small-duct system add air conditioning without touching the radiators.
