Central Minnesota Heating and Cooling repairs and replaces furnaces, ACs, heat pumps and boilers in Spring Park (Hennepin County), about 18 miles from downtown Minneapolis.
Spring Park is one of the smallest cities on Lake Minnetonka, about 1,700 people on roughly six-tenths of a square mile, with about two-fifths of that area water, set between Mound and Orono.

Book in Spring ParkSpring Park sits on a narrow piece of shoreline that was once the grounds of Hotel Del Otero, a summer resort built by James J. Hill, and the city was incorporated in 1951 with only a couple of hundred residents. Tonka Toys had its headquarters here from 1946 to 1991. Housing since then has filled the small space the lake leaves, so the lots are tight and the buildings sit close together.
What that means for heating and cooling is mostly about room. A furnace may be in a closet beside the water heater, and a replacement has to match the opening, the door and the vent route. Outdoor units go wherever the lot permits, often a few feet from a neighbor's window. Any house or building that began as seasonal lake housing may have had heat added later, so the ductwork can be improvised, and we trace it before promising how a new system will perform. Newer buildings are usually simpler, though shared walls and shared rooftops still limit where equipment can go.
Wind comes across the open ice of Lake Minnetonka, and a house this close to the shore feels it on the lake side first. Rooms facing the water lose heat faster than the rest, which can make a furnace that is only a little undersized seem much weaker than it is. Side-wall vents and heat pump outdoor units on a small lot also collect drifted snow and ice quickly, so they need to be kept clear and above the snow line.
Being beside the water means humid summer air, and in small lake homes it lingers in lower levels and crawlspaces after the thermostat is satisfied. A well-matched air conditioner removes that moisture, but an oversized one cools too quickly and shuts off before it can. On a small lot the condenser also sits close to the house and the neighbors, so we pay attention to clearance, airflow and how much noise carries across the property line.
Spring Park's gas and electric providers depend on your address, so look at your bill to see which utility serves you. CenterPoint Energy and Xcel Energy both run rebate programs for heating and cooling equipment, and the dollar amounts and rules change every year, so read their current pages before you buy. Some rebates require a utility-registered contractor, so ask that question before you choose who installs the equipment.
Rebate programs change every year; check the utility's current terms before you buy. Our guides: heat pump rebates, what happened to the federal credits.

The City of Spring Park lists a Permits and Licensing department on its website, with building permit application forms and a fee schedule. A furnace, boiler, AC or heat pump replacement normally needs a mechanical permit. Check the city's current forms for what applies to your job.
Often yes. Furnaces come in several cabinet sizes, and some are built for tight spaces. What we measure is the opening, the clearance in front for service, the vent route and the condensate drain, since a high-efficiency model vents through PVC. If nothing fits, a ductless heat pump system or relocating the furnace may be the better plan.
It has to meet the manufacturer's clearances on every side, stay off the shared lot line where possible, and sit on a level pad above the snow line. We look at the lot before we quote, and if your city or association has placement rules, we follow them. A ductless outdoor unit is smaller and can sometimes go where a central condenser won't.
Humid lake air gets in through lower levels and crawlspaces, and an air conditioner that cycles on and off too fast cools the air without removing much of the moisture. We check the system's sizing, airflow and drain, and look at the ducts and crawlspace. A dedicated dehumidifier or sealed, insulated ducts often solve it.
