Ductless Mini-Splits in Lakeville, MN
Ductless mini-splits in Lakeville cost about $4,200–$12,500 installed, for the bonus room over the garage and older homes with additions. They are a common fix for the bonus room over the garage that gets too little air from the builder's long duct run, and for older homes with additions.
Mini-split installs in Lakeville homes
In Lakeville's newer neighborhoods, the typical complaint is a room that doesn't keep up: a bonus room over the garage, a loft or a finished lower level at the end of a long duct run. The builder system was sized for the floor plan on paper, and these rooms get whatever airflow is left. A single ductless head puts heating and cooling right where it is needed, and it often costs less than rebuilding the ductwork.
The 1970s and 1980s homes near downtown and around Lake Marion and Orchard Lake are in a different spot. Their additions, sunrooms and three-season porches often never got ducts, and a head solves them with a thin line set.

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. A bonus room or loft at the end of a long builder duct run needs one head, and older homes with additions add more. Compare central AC vs ductless costs.

Mini-splits in Lakeville: questions
Will one mini-split head fix a hot bonus room over a Lakeville garage?
Often it does. Rooms over garages get hit by outdoor temperatures from below, and a long duct run delivers weak air. A head in the room gives it independent cooling and some heat, and the main system doesn't have to be oversized. We check the room's size and exposure, then quote the head in writing.
Can I add a mini-split to a Lakeville sunroom or three-season porch?
Yes, and glass-heavy rooms like these are common candidates. A cold-climate head can make them usable most of the year, though a room with lots of glass loses heat quickly on the coldest days. We size to your worst weather and tell you what temperature to expect. The quote is written and flat rate.
