St. Francis grew up around Dwight Woodbury's 1855 dam and mills on the Rum River, the river Louis Hennepin had called the St. Francis in 1680, and it stayed small until its population more than tripled between 1990 and 2020.

What heating systems do St. Francis homes have?

Until the 1960s St. Francis was a village of a few hundred people, so the older houses are a small group near the original village along the Rum River. Most of today's homes came with the subdivisions of the 1990s and 2000s, when the population went from about 2,500 to more than 7,200, and a lot of their builder-installed furnaces and condensers are now at replacement age. The city limits also take in open land and larger rural lots, some of them beyond the gas lines.

CenterPoint Energy supplies natural gas in St. Francis, though homes on rural parcels beyond its lines may heat with propane.

What are St. Francis homes like to heat and cool?

The village that grew around Woodbury's mills had creameries, mills and a starch factory, but the railroads went through Cedar and Bethel instead, industry drifted away, and a 1933 fire took the old gristmill and the dam across the Rum. The Woodbury family's house overlooking the river became the Riverside Hotel and still stands on Bridge Street. St. Francis had fewer than 900 people in 1970, so older houses are few, and the ones that remain have usually been remodeled and re-equipped more than once.

Then the city filled in. The population went from about 1,200 in 1980 to 7,200 in 2010, so the typical St. Francis house is a 1990s or 2000s subdivision home with a basement furnace, PVC venting and a condenser out back. Furnaces from the 1990s have reached the end of a normal service life, and some air conditioners from before 2010 still use R-22. On the rural edges of the city, larger parcels may sit beyond CenterPoint's gas lines and heat with propane.

What goes wrong with heating in St. Francis in winter?

January finds the weak spots in St. Francis's 1990s and 2000s houses. On condensing furnaces that are now 20 or 30 years old, the condensate trap and its rubber hoses clog or crack, water backs up, and the pressure switch shuts the furnace down on the coldest night of the month. Exhaust pipes that leave a side wall under a deck frost over the same way. Along the Rum River, low ground can hold cold air on still nights, and the older houses near the water lose heat faster than the subdivisions.

What goes wrong with cooling in St. Francis in summer?

Many St. Francis air conditioners date from the 1990s and 2000s building boom, and those installed before 2010 may run on R-22, which is no longer produced. That makes summer the season of hard choices: a failed capacitor is a small fix, but a refrigerant leak on an R-22 unit usually points to replacement. Muggy nights along the Rum River keep systems running well after dark, and cottonwood fluff can mat outdoor coils by early summer, so rinse them gently before the first heat wave.

AC repair in St. Francis

Which utilities and rebates apply in St. Francis?

St. Francis pairs CenterPoint Energy gas with Connexus Energy electricity, which opens programs on both sides. CenterPoint's furnace and boiler rebates work with any installer if you file within the install year, and a ducted heat pump qualifies only with a gas furnace as its backup. Connexus rebates heat pumps and central air, and it bills heat pump heating at a reduced rate when an automatic furnace stands behind it. Don't plan around Minnesota's HEAR or HOMES rebates; neither had launched as of mid-2026.

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.

Our late-1990s St. Francis house is still on the builder's furnace. Replace it now or wait?

Not automatically, but plan for it. A furnace that age has run more than 25 Minnesota winters. We'll repair it for an igniter or flame sensor, but a cracked heat exchanger, a failed inducer on top of other repairs, or a control board that's no longer made usually tips it to replacement. A written quote in the fall beats choosing equipment during a January no-heat call, and CenterPoint's rebate is filed the same calendar year.

Can an older house near the Rum River in St. Francis get central air without new ductwork?

Yes, two ways. Ductless heat pumps put small heads in the rooms that need them, with refrigerant lines through the wall, and they heat in spring and fall too. Or a high-velocity system feeds each room through small flexible tubes snaked through closets and walls; national cost guides such as HomeGuide put those at $3,500–$15,000+ installed. We look at the house, the rooms you use and the electric panel before recommending either.

We have CenterPoint gas and Connexus electric in St. Francis. What's the best way to add a heat pump?

Usually a ducted heat pump paired with your gas furnace. CenterPoint only rebates a ducted heat pump when a gas furnace backs it up, and that same furnace is the automatic backup Connexus Energy requires for its lower heating rate. The heat pump cools in summer and carries the milder heating days, while the furnace handles deep cold and any stretch when Connexus interrupts the heat pump during peak demand.

We bought one of the older houses in the original St. Francis village. What should a heating check cover?

Start with safety: working CO alarms within 10 feet of every bedroom, which Minnesota law requires, and a draft test on anything venting into the chimney. Older houses often have a furnace that has been replaced several times on ductwork that wasn't, so we measure airflow and look for rooms fed by one small run. Then we check the heat exchanger, the gas piping and the age of the air conditioner.
