Cooper Cooling & Heating works across Brooklyn — Park Slope, Bedford-Stuyvesant, Crown Heights, Bushwick and Williamsburg, out through Flatbush, and down into Bay Ridge and Sunset Park. Brooklyn asks for a different answer than Manhattan does, and mostly for one reason: a great many of these buildings have no ductwork at all and never did.
Buildings that were never designed to be cooled
Brownstones, rowhouses and pre-war walk-ups were built around steam and hot-water heat. Radiators under the windows, pipe risers through the floors, and nowhere in the structure that a duct run was ever meant to go. Cooling was simply not part of the design.
That makes ductless the default retrofit here, and the equipment is rarely the hard part. Daikin, Mitsubishi and Fujitsu all make excellent multi-zone systems. The difficult work is routing: getting a line set from a condenser to a head on the third floor of an occupied house without tearing through finished plaster, and finding somewhere the outdoor unit can legally sit. Roofs, rear yards and narrow side alleys are the usual candidates, and each carries its own constraints around clearance, support, drainage and noise to the neighbour.
Landmarked blocks add a further layer. Across the historic districts in Park Slope, Brooklyn Heights, Crown Heights North and parts of Bed-Stuy, what may be visible from the street is genuinely restricted. A condenser placement that is routine three streets away can be refused here, so on those blocks siting gets planned before anything is quoted rather than discovered on the day.
Three different Brooklyns, three different jobs
The rowhouse belt — Bed-Stuy, Crown Heights, Bushwick, Park Slope — is the ductless retrofit work above, usually paired with an ageing steam or hot-water boiler that also serves the domestic hot water. That shared duty is why a no-heat call and a no-hot-water call in these houses so often turn out to be the same call.
The waterfront and downtown is the opposite problem. The newer towers through Williamsburg, Greenpoint and Downtown Brooklyn run PTAC and water-source heat pumps exactly as Manhattan does, on building condenser-water loops with managing agents, alteration agreements and certificates of insurance. Island Aire, Ice Air, Omega and Climate Master matter here for the same reasons they matter across the river.
The freestanding houses are the part people forget Brooklyn has. Victorian Flatbush and Ditmas Park hold detached wood-frame houses on their own lots, with basements and yards, and Bay Ridge and Sunset Park run to attached and semi-detached brick with usable rear yards. These can take conventional split systems and, where there is space to run duct, genuine central air with an American Standard or Goodman furnace on the heating side. It is the one part of the borough where the full central-air conversation is realistic.
Radiators that were balanced once, decades ago
A recurring Brooklyn call is a top floor that overheats while a rear room stays cold. On steam and hot-water systems that is almost never a capacity problem at the boiler — it is venting and distribution balance that has drifted over sixty or seventy years. Replacing the boiler will not fix it, and we will say so rather than quote you the larger job. Two-family conversions add the zoning question on top: separate units nearly always want separate control that a single original boiler was never piped to provide.

A flat fee to find out what is wrong
Repairs carry a flat $175 diagnostic, quoted before we book. You get the diagnosis whether or not you go ahead with the work, which is what lets us tell you a boiler is fine when it is fine. Estimates run Monday to Friday, 9am to 5pm, and Saturday mornings. Permits, where a job needs them, go through NYC DOB.
