Our Services

Central air conditioning installation, replacement and repair for homes and commercial spaces. Ducted systems fail in a small number of predictable ways — a failed capacitor, a seized condenser fan, a refrigerant leak, a blocked coil, a control board — and the job is finding which one before replacing anything. If the system is old enough that a repair is money spent twice, you will be told that.

Ductless mini-split installation and service for homes and small commercial spaces. Mini-splits are what you fit when running ductwork is impossible or absurd — a pre-war apartment, a converted floor, a back office, an addition. They heat as well as cool, they zone room by room, and a correctly sized and correctly charged one is among the quietest and cheapest systems to run.

Commercial rooftop HVAC units — installation and service. An RTU is a packaged system doing the whole job in one cabinet on the roof, and it is the one thing on this list that is commercial only: restaurants, shops, offices, small warehouses. When an RTU goes down the business is what stops, so these get treated as urgent by default.

Furnace installation, replacement and repair. A furnace that will not light, short-cycles, blows cold or trips on a limit switch is usually telling you something specific — a dirty flame sensor, a failed igniter, a blocked flue, a pressure switch, a cracked heat exchanger. Some of those are a cheap part and some of them mean the furnace should be condemned, and the difference matters more than the price.

Boiler installation, replacement and repair. Boilers heat a large share of New York City housing, and they fail in ways that are specific to them: a failed circulator, an airlocked riser, a gas valve, a low-water cutoff, an expansion tank, pressure that will not hold. Cold radiators on the top floor and a warm basement is a circulation problem, not a dead boiler, and the two get very different bills.

Tank water heater installation and replacement. Most tanks give you eight to twelve years, and they rarely fail politely — the usual sequence is lukewarm water, then rusty water, then a puddle. Replacing one before it splits is a planned afternoon; replacing one afterwards is a planned afternoon plus a flooded floor.

Tankless (on-demand) water heater installation and service. A tankless unit heats water as it flows, so it does not run out and it is not paying to keep a tank hot all day. It also asks more of the installation — gas supply, venting and flow rate all have to be right, and in a hard-water building it needs descaling — which is exactly why a badly installed one disappoints and a properly installed one does not.
