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.
What goes wrong with heating in South St. Paul in winter?
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.
What goes wrong with cooling in South St. Paul in summer?
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, 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. 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.

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 a replacement normally needs a city mechanical permit.
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.
Central air was added to our 1950s South St. Paul house years ago. Will the old ducts handle a new AC?
Often they were sized for heating, and cooling moves more air. Before quoting, we measure static pressure and check whether the return is large enough and whether the supplies reach the upstairs rooms. Leaky seams and an undersized return are the usual fixes, and the new coil has to match the furnace blower. If the ducts can't carry the air, we tell you before you pay for a bigger condenser.
The furnace in our 1950s South St. Paul basement shares a room with the laundry. What does a replacement need?
Room to work and clean air. The furnace needs the clearances on its nameplate, a path to open the panels, and enough combustion air, which a tight utility room with a dryer pulling air out can lack. Lint near the burners is a fire and breakdown risk, so keep the dryer area swept. A sealed-combustion 90%+ furnace draws outdoor air through PVC and sidesteps most of this.
