Central Minnesota Heating and Cooling repairs and replaces furnaces, ACs, heat pumps and boilers in Eden Prairie (Hennepin County), about 13 miles from downtown Minneapolis.
Eden Prairie grew from 6,978 residents in 1970 to 64,198 in 2020, so its houses run from 1970s walkouts above Purgatory Creek and Staring Lake to 1990s and 2000s two-stories and townhomes near the Minnesota River bluffs.

Book in Eden PrairieEden Prairie had about 2,000 residents in 1960, and after Interstate 494 and Eden Prairie Center arrived in the 1970s, its population grew nearly 3,000 percent by 2000. The Preserve, launched in the early 1970s as a planned 'new town' and co-developed by Minnegasco, was one of the first big projects, mixing single-family homes, townhomes and apartments around open space. Those early houses are now on their second or third furnace, often with original ductwork and a chimney.
Through the 1980s and 90s, building spread across the rolling land between Purgatory Creek, Riley Creek and the Minnesota River bluffs, with two-stories, walkouts and large townhome associations. The 1990s and 2000s added bigger houses in developments such as Bearpath and Hennepin Village, where two-story great rooms, finished lower levels and more than one system are common. Those tall great rooms, with a wall of windows and a ceiling two floors up, bring heating and cooling problems of their own.
In Eden Prairie's 1970s neighborhoods, including The Preserve, winter often exposes a 50-year-old chimney and a furnace that's due. In the larger 1990s and 2000s homes, the trouble is more often a second furnace or zone nobody checked until a bedroom wing went cold. The rolling terrain also puts PVC vents on the downhill side of walkouts, where drifting snow collects against the lowest wall of the house.
Lake Riley, Staring Lake and the Purgatory Creek wetlands keep summer air humid, and walkout lower levels facing them can smell musty when the air conditioner short-cycles. Two-story great rooms with big south or west windows pick up afternoon sun, and heat collects at the top of the room and in the upstairs hallway. In houses with two air conditioners, a unit that fails quietly shows up as the other one running nonstop, so check both in spring.
CenterPoint's heating rebates cover high-efficiency furnaces and let you choose your own dealer, but the application has to go in the same calendar year as the install and a quote doesn't count as proof of purchase. Xcel handles heat pump and central AC rebates through its Trade Partner Network, so ask whether the rebate needs a registered contractor. Its AC Rewards program pays an annual reward for enrolling a qualifying smart thermostat.
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.

The walkout has glass and siding on one side and earth on the others, while the main floor picks up sun and rising heat. A thermostat upstairs can't read what the lower level needs. Balancing dampers help a little. A zoned system, with a second thermostat and motorized dampers in the ductwork, paired with a variable-speed blower, fixes it properly.
Yes, association rules can change the install. Many associations limit where the outdoor unit sits, what it sits on, and how line sets and PVC vents pass through the siding. Some require written approval before work starts. Get us a copy of the rules early so the quote reflects the allowed location, and allow for the association's review time if the old unit is failing in July.
Moving air where the room needs it. Warm air stratifies near a two-story ceiling and cold air falls off tall windows, so a supply register under the glass and a return placed low help in winter. A variable-speed blower running on low all the time mixes the room, and a ceiling fan helps in both seasons. If the great room shares a thermostat with the kitchen, a separate zone may be the real fix.
The furnace moves to PVC intake and exhaust through a side wall or the roof, plus a condensate drain, and it stops using the chimney. A gas water heater left alone in that flue may not draft well, so the quote should include a liner or a water heater that vents itself. We check the chimney and the vent route before pricing.
