Ductless mini-split installation in Norwood Young America costs $4,200–$12,500 with a written flat-rate quote. Rear additions, finished attics and rooms over crawlspaces are the usual jobs in the older houses.
The kitchens, mudrooms and family rooms added onto the back of older Norwood Young America houses were often built over a crawlspace with one or two ducts run through the cold space. They run cold in winter and hot in summer, because they usually have more windows than the original house and no return air path. A ductless head gives such an addition heating and cooling of its own, with its own thermostat, without extending ducts through a crawlspace.
Finished attics and upstairs bedrooms in the 1880s to 1920s houses are the other regular job, since the original system rarely reached them well. A head upstairs works with air sealing in the knee walls. In the newer subdivisions, a bonus room over the garage runs cold for the same reason as the old additions: unheated space underneath.

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. An addition over a crawlspace needs insulation work for the head to perform, and a finished attic adds line-set length compared with a first-floor room. Compare central AC vs ductless costs.
Usually, yes, though insulating the crawlspace walls and sealing leaks at the rim joist helps first. The head runs independently of the furnace, so the addition no longer depends on a duct that crosses the unheated crawlspace. We size it from the addition's load and window area.
Xcel Energy supplies the electricity there and has heat pump rebates, but rules differ by equipment type and change yearly. Ask Xcel whether a mini-split qualifies and whether the rebate needs a registered contractor before you buy. We write model numbers on the quote so you can check the requirements.
