Book in South St. PaulWhat are South St. Paul homes like to heat and cool?
South St. Paul incorporated in 1887, and industrial jobs, led by the stockyards and packing plants, pulled the population from about 4,200 in 1900 to a peak of 25,106 in 1970. Industry filled the floodplain along the river, and houses went up on the bluff above it. The oldest blocks, west of Concord Street, hold houses old enough to have started on coal or oil before gas, and by 1980 about 85 percent of the city's current housing was already standing.
The decline began in 1978, as the stockyards and packing plants wound down, and the stockyards closed for good in 2008. The city cleared old stockyard buildings for business parks, and a former demolition landfill on the river became Kaposia Landing. Very little new housing followed: from 2008 to 2017 the city issued fewer than 10 single-family building permits a year. Most furnaces here sit in basements that have held several before them, and a replacement means working with a masonry chimney, older gas piping and the changes earlier owners made.
Winter in South St. Paul
Cold snaps expose the add-ons in South St. Paul's older houses. Walls that may never have been insulated lose heat fast, and owners sometimes fill the gap with a space heater. The city's time-of-sale guidelines treat any ventless gas heater as hazardous, along with any fuel-burning heater that draws combustion air from a bedroom, so those are better replaced now than before a sale. In a hot-water boiler house, bleeding air from the radiators and checking the expansion tank and relief valve each fall prevents cold rooms later.
Summer in South St. Paul
A radiator-heated South St. Paul house has no ducts to carry cold air, so cooling means window units or ductless heads, one per floor or per bedroom; where closets line up, a high-velocity small-duct system can serve the whole house. In the 1950s blocks, central air was added to the furnace later, and a condenser made before 2010 could be an R-22 unit, which makes any refrigerant leak a repair-or-replace decision. Where a lot slopes, check that the condenser pad hasn't settled out of level.
Which utilities and rebates apply in South St. Paul?
Every South St. Paul address buys electricity from Xcel Energy, but the city lists two gas companies, Xcel Energy and CenterPoint Energy, so check your gas bill first. 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. Xcel's Residential Cooling Rebates, Saver's Switch and AC Rewards apply citywide.
Rebate programs change every year; check the utility's current terms before you buy. Our guides: Xcel and CenterPoint rebates, heat pump rebates, what happened to the federal credits.

South St. Paul HVAC questions

We're selling our South St. Paul house. What does the time-of-sale evaluation check on the heating system?
A city-licensed housing evaluator looks at the furnace or boiler, its safety controls, the vent pipe into the chimney and draft at the water heater, and runs the heat during heating season. Items marked Hazardous, such as a vent pipe with holes or gaps, spillage at the draft hood or a cracked combustion chamber, must be fixed before the buyer takes possession. We can make those repairs and pull any permit they need.
Can we leave the ventless gas heater in our South St. Paul garage when we sell?
No. South St. Paul's time-of-sale guidelines don't allow ventless gas heaters in houses or garages. The evaluator marks one Hazardous, and it has to be removed, with the gas line properly capped, before the new owner takes possession. If the garage needs heat, a vented unit heater that sends its exhaust outdoors is the usual replacement, installed with the right clearances and a gas line sized for it.
Our pre-war South St. Paul house heats with hot-water radiators. How do we add air conditioning?
Without ducts, the choices are ductless mini-splits or a high-velocity small-duct system. Ductless heads mount on walls or ceilings and run off one or more outdoor units; our installed range for ductless is $4,200–$12,500. High-velocity systems feed small tubing through closets and attic space, and national cost guides such as HomeGuide put them at $3,500–$15,000+. Either way, the boiler and radiators stay as they are.
Our South St. Paul neighbor's gas bill comes from CenterPoint and ours from Xcel. Does that change a furnace rebate?
It can. The city lists both companies as gas suppliers, and the furnace rebate follows whichever one bills you. CenterPoint doesn't restrict which dealer installs the furnace, but it wants the application filed within the calendar year of the install. Xcel's furnace rebate page points you toward a participating contractor, so ask before you sign. We confirm your gas utility when we quote the job.
