A classic six deserves cooling it never has to look at.
The Upper West Side's prewar apartments — the classic sixes and sevens along the avenues — carry plaster, beams, and moldings that rule out ordinary ductwork, and owners here want cooling the architecture never has to acknowledge.
Concealment as the design brief.
The prewar cooling solution this neighborhood favors is the concealed ducted system: compact air handlers hidden above hallway and closet ceilings, short duct runs feeding linear diffusers that read as trim, and the living rooms, dining rooms, and bedrooms left architecturally untouched. Done well, the only visible evidence is a quiet slot in the hall ceiling. Doing it well is the discipline — soffits planned where the eye forgives them, returns placed so doors can stay closed, condensate routed with somewhere legal to go, and the whole design drawn for the board's alteration review before a single tool arrives.
Living with the steam.
The building's steam heat stays the building's business, and our systems are designed alongside it rather than against it — cooling sized for apartments that will always be generously heated, and humidity handled for interiors where radiators dry the winter air.
Frequently Asked Questions
Upper West Side questions, where concealment is the design brief.
Can our prewar apartment get central-feeling cooling without visible units?
In most layouts, yes. Concealed ducted systems above halls and closets cool whole apartments through diffusers most guests never notice. The assessment maps your ceiling heights and routing options, and the drawings go to the board before anything proceeds.
Where does the outdoor equipment go in a prewar building?
Wherever the building has granted rights — typically a setback, courtyard, or roof position — and confirming that placement with management is one of the first steps of the proposal, not the last.
Pacific Air also serves neighboring Harlem and the Upper East Side.
