Book in Lester PrairieLester Prairie nearly doubled between 1950 and 1970, from about 660 residents to more than 1,100, so a big share of its houses are 1950s and 1960s ramblers and story-and-a-halfs. Those went up with a basement furnace, heat-only ducts run through the joists and no plan for air conditioning. The oldest homes sit on the 1886 town site near the old rail grade that now carries the Dakota Rail Regional Trail, and a few of those still vent through their original brick chimney.
After a flat stretch through the 1980s, the town grew again from the 1990s on, adding homes at the edges with 90%+ furnaces vented in PVC and central air installed with the house. The South Fork of the Crow River passes the southeast corner of town.
Acreage homes around Lester Prairie on McLeod Cooperative Power often heat with electricity on an off-peak or dual-fuel rate. On those programs the co-op can switch electric heat off during peak demand, and peaks often land on the coldest evenings. When that happens, the backup furnace has to carry the house, so test it in the fall: check the propane level, run the furnace on its own for a full cycle and make sure the thermostat hands off correctly. A backup that fails quietly shows up as a cold house at 6 a.m.
The 1950s and 60s story-and-a-halfs in Lester Prairie heat up from the top. Their upstairs rooms sit under the roof beside knee walls with little insulation, and they rarely got a return, so a central air system added to the basement furnace cools the main floor and leaves the bedrooms warm. Sealing and insulating the knee walls helps first. After that, a small ductless head upstairs or a new return path does more than a bigger condenser, which only makes the main floor colder.
Xcel Energy supplies electricity in town and offers heat pump and residential cooling rebates; ask whether the one you want requires a registered contractor. Rural homes on McLeod Cooperative Power follow the co-op's own heat pump rules instead. For a gas furnace, the rebate comes from whichever utility sends your gas bill, so check it before you buy.
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.

Xcel Energy provides electricity in town, and McLeod Cooperative Power may serve rural homes around it. Gas furnaces are standard in town, and farms and acreage outside it commonly burn propane. Which company supplies natural gas depends on your address, so the name on your gas bill decides whose furnace rebate applies.
Yes. McLeod Cooperative Power rebates air-source and geothermal heat pumps, but they must be installed by a certified, registered Quality Installer and pass a co-op inspection, and off-peak heating equipment has to be hard-wired. We set up the controls so the propane furnace takes over when the co-op switches the heat pump off.
Usually. Saver's Switch is an Xcel Energy program that cycles your central air conditioner off and on during peak summer demand in exchange for bill savings. It works with standard outdoor units, and on the hottest afternoons the house may run a little warmer than usual. If you would rather use a smart thermostat, Xcel's AC Rewards program does a similar job through the thermostat and pays an annual reward.
Repair or replacement depends on what failed. At 25 to 30 years, an igniter or a blower capacitor is still worth fixing, but a cracked heat exchanger, a failed control board for an obsolete model or a worn-out blower motor usually points to replacement. We inspect the heat exchanger, test for carbon monoxide and give you a written price for the repair and for a replacement, so you can decide with both numbers in front of you.
