Ductless mini-splits in Lino Lakes run $4,200–$12,500 installed, single-zone to multi-zone, always priced flat-rate in writing. They work for a lake-facing walkout level, a sunroom, a garage conversion or a farmhouse addition that the main system doesn't reach well.
The wall of glass that sells a Lino Lakes walkout is also what makes its lower level hard to condition. The room faces the water, the air turns humid in July, and the main system, controlled from upstairs, either overshoots or cycles too briefly to dry it. A ductless head sized to that room runs on its own thermostat and its own schedule, so it can dehumidify without the rest of the house getting cold.
There are also the older homes scattered among the newer ones: farmhouses, 1960s and 70s ramblers on larger lots, lake homes of mixed ages. Those often have additions or porches that were never on any duct plan, and a few have no ductwork to speak of. Ductless needs only a line set through the wall. We also leave clear service access to each indoor head.

Our $4,200–$12,500 installed price comes as a written flat-rate quote, with a 2-year labor warranty on top of the manufacturer's parts warranty. Walkouts with glass facing the water often need a dehumidifying head sized for that level, while a garage conversion, sunroom or farmhouse addition adds one more.

It can help a lot. A head sized to the room runs longer cycles and removes more moisture than an oversized unit that shuts off quickly. It also lets you condition the lower level without running the whole house system. If the dampness comes from water entering the basement, that has to be fixed separately.
It can heat the rooms with heads in them, and cold-climate models keep working in sub-zero weather, though output drops as it gets colder. For a farmhouse or lake home with a boiler or baseboard system, ductless adds cooling and takes some of the heating load. We tell you which rooms a head can carry.
