Central Minnesota Heating and Cooling repairs and replaces furnaces, ACs, heat pumps and boilers in Mound (Hennepin County), about 20 miles from downtown Minneapolis.
Heating and cooling work in Mound runs from a $129 tune-up to $4,500–$9,500 for a furnace replacement, all on written flat-rate quotes. Mound wraps around the west end of Lake Minnetonka, with Black, Dutch, Langdon, Saunders and Seton lakes inside its borders and many lake cabins converted to year-round homes.

Book in MoundMound grew out of Lake Minnetonka's cabin era, and the small lots platted along Cooks Bay, Harrison Bay and the smaller bays still set the pattern: narrow frontages, houses a few feet apart, and additions that went up instead of out because there was nowhere else to go. Many conversions went from a stove to a wall furnace or baseboard when someone moved in year-round, then to a forced-air furnace later, and the ductwork shows every stage.
Farther from the water, the city filled in with postwar ramblers, then 1960s and 1970s split-levels and some two-stories on higher ground. Those are standard basement-furnace houses, with ducts now 50 or more years old and usually due for sealing even when the furnace is new. Newer townhomes and apartment buildings near downtown add closet mechanicals and stacked units, which set the limits on replacement. Lots are small almost everywhere, so an outdoor unit usually ends up within a few feet of the property line.
Wind from the west comes across the open ice of Cooks and Harrison bays with nothing to slow it, and shoreline homes lose heat through their floors as much as their walls when the crawlspace below is vented. Converted cabins are the first to freeze pipes and the last to warm up. A heat pump on the lake side of the house needs a stand that holds it above drifting snow. Closet furnaces in small houses often draw combustion air from the living space, where bath and kitchen fans can work against them.
Mound lives with lake humidity from June to September. Crawlspaces sweat, older ducts running through them grow mold if they aren't sealed and insulated, and window-unit cottages feel sticky even when the air is cool. Ductless heat pumps remove moisture as they cool, one reason they suit the small converted cabins. Upstairs additions under low roofs run hot, and many lack a return, so the air conditioner can't pull the heat back down from those rooms.
Mound's gas comes from CenterPoint Energy and its electricity from Xcel Energy. For the baseboard-heated and converted-cabin homes, Xcel's rebates are the ones that count: they cover air-source heat pumps and ductless mini-splits, and many measures need an Xcel-registered contractor, so ask first. Xcel also offers Heating Upgrade Rebates for electric space heating. CenterPoint's heating rebates cover high-efficiency gas furnaces, boilers and thermostats, installed by the dealer you choose.
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 best heat for a converted Mound cabin depends on the crawlspace. If there's headroom, and the crawl can be sealed and insulated so the ducts sit inside the heated envelope, a furnace or ducted heat pump works. If the ducts would run through a cold, vented crawl, ductless heads usually win, because nothing is losing heat under the floor. We look under the house before recommending either.
Often, yes. Baseboard turns electricity into heat one for one, while a cold-climate heat pump moves heat from outdoors and uses less electricity for the same warmth through most of a Minnesota winter. Output drops in deep cold, so we keep the baseboards as backup. Small converted cabins are good candidates because one or two ductless heads can cover most of the floor plan.
A wall furnace can run safely for years if it's inspected. We check the burner, the vent connection and the heat exchanger, test for carbon monoxide and confirm the thermostat and safety controls work. Many are old enough that parts are hard to find. When one fails, a small ductless heat pump system or a compact direct-vent furnace usually replaces it, and CO alarms within 10 feet of each bedroom are required either way.
Usually the smell starts underneath. Ducts or an air handler in a damp crawlspace pull musty air in through leaky joints, and a dirty coil or a slow condensate drain adds to it. We check the crawlspace, the duct seams, the coil and the drain pan. Sealing the ducts, fixing the drain and controlling crawlspace moisture with a vapor barrier or a dehumidifier usually clears it up.
Natural gas for most of the city: CenterPoint Energy mains reach the bulk of Mound's streets. The exceptions are some converted cabins that still run electric baseboard or a gas wall furnace. Check your bill or look for a meter on the house. If a gas line isn't there, ductless heat pumps are the usual alternative to propane.
