Small Space, Big Solution | Medfield Ceiling-Mounted Mini-Split by SumZero
Not every comfort issue requires a massive overhaul. In this Medfield home, the homeowners had one specific area they wanted to heat and cool—but with a twist: they didn’t want a wall-mounted unit. Our team at SumZero delivered a sleek, single-zone ceiling-mounted mini-split that blends beautifully with the space and performs down to -13°F. Watch how even a smaller project can make a big difference when it’s done right.
