Concealed-Duct Mini-Splits
Slim-duct units hide in a ceiling, soffit, or closet and feed short duct runs to two or three registers — mini-split efficiency with no visible equipment at all. They're the compromise between a wall head in every room and a full central system, and the go-to for renovations where sightlines matter. The honest catches: static pressure limits mean duct runs must stay short and well-designed, install complexity (and cost) approaches conventional ducted work, and an undersized return will strangle the unit's efficiency. This is pro-design territory — but the result is the most invisible heating and cooling a retrofit can buy.
The catalog has 4 concealed-duct units from 3 brands, priced from ~$1,413 to ~$3,790. The one that keeps heating coldest is the Pioneer Quantum Ultra 12,000 BTU Concealed Duct (rated to -13°F).
