Not sure a mini split is the right answer? (320) 400-0991
A mini split puts heating and cooling exactly where you need it, without adding ductwork. In Minnesota the heating side matters as much as the cooling.
A room built after the ductwork went in, always too hot or too cold whatever the thermostat says.
Heated and cooled space without extending the house system into a building that was never designed for it.
Second floors that the central system cannot keep up with in July.
Older houses on boilers or radiant heat, where adding central air would mean tearing into walls.
Heat or cool one space without conditioning the whole house to do it.
We repair and maintain existing mini splits as well as installing new ones.
