Can you add modern cooling without harming historic interiors?
HVAC for Brooklyn Heights brownstones and prewar co-ops
Brooklyn Heights homes come with strict finish expectations and building requirements. Typical buildings are landmarked brownstones and prewar co-ops heated by steam or hot-water boilers, with central ducted splits, mini-splits or VRF for cooling. What we usually see here is historic-district limits on visible equipment, and tight mechanical rooms in brownstone cellars.
Modern comfort without damaging historic interiors
We specialize in discreet comfort: high-velocity systems and mini-split heat pumps that deliver modern cooling without harming masonry, woodwork or interiors. Each job is planned around the building, including how equipment gets in, where condensers can go, and what the neighbors and the board need to sign off on. We confirm placement, line-set routing and any approvals before the install date, and we keep stoops, stairs and finished floors protected while we work.
