Applied Comfort: PTAC Units Built to Your Existing Sleeve
Most of New York's housing was built before the 42 x 16 sleeve became the norm, and much of it heats from a boiler in the basement. Applied Comfort builds the chassis to the opening and the heat source already in your wall. You change the unit. You keep the louver, the brick, and the board's approval.

When Applied Comfort is the answer
Choose Applied Comfort when an off-the-shelf PTAC does not fit the wall or the heating plan. In New York that usually means one of these:
- A sleeve that is not 42 x 16. Common widths in older buildings include 32, 36, and 44 inches, plus three-piece K installations.
- A discontinued brand. McQuay, Singer, Remington, AAF, Slant Fin, Climate Master, Zoneaire, Keeprite, and older regional models from Long Island and Westchester makers.
- A hot water coil on the building boiler. Co-ops and rental towers that heat centrally need a hydronic replacement, on legacy or 42 x 16 sleeves.
- A facade you cannot touch. Landmarked buildings, historic districts, and co-op boards that will not approve a new louver.
On standard 42 x 16 sleeves with hydronic heat, the NA, NF, and NY series cover slope-top, flat-top, top-coil, and bottom-coil layouts that an electric PTAC does not.

The legacy sleeves New York runs on
The city's postwar building boom filled walls with sleeves from manufacturers that have since merged, quit, or changed sizes. Here is where they turn up most:
Bronx, Queens, and Brooklyn developments with one legacy sleeve in hundreds of rooms and a boiler feeding every coil.
White-brick buildings on the East Side, West Side, and in Lower Manhattan with original McQuay or Singer sleeves.
Complexes with sleeves from regional makers and brands no longer on the market.
Properties that never gutted the rooms and still run the original opening.
Older Trane, Friedrich, Amana, Carrier, Islandaire, and Ice Air installations, and discontinued GE Zoneline series, land on a 42 x 16 path or a legacy path depending on the sleeve. The tape measure decides. How to tell standard from legacy.
Keep heat on the boiler
In a centrally heated building, the boiler is the heat plan. A hydronic replacement keeps it that way.
- The coil sits in the same position, top or bottom, so the supply and return lines connect without new piping.
- The owner keeps paying for heat through the boiler, as the building was designed.
- Heating stays under the building's control during the season the city requires heat, October 1 through May 31.
Moving rooms off the boiler to electric heat is a bigger decision. It changes who pays for heat and, in buildings covered by Local Law 97, how emissions are counted.
Voltage, circuits, and controls
- Applied Comfort builds to the voltage the building supplies. Read it from the old nameplate.
- Note plug-in or hardwired. Many legacy units are hardwired, especially at 265V.
- Record the breaker size. Electric heat, where used, is sized to it.
- Tell us about wall thermostats. Select series accept a 24V remote thermostat.
Before you request a quote
The sleeve decides the build. Get these right and the chassis fits on the first try.
- Measure inside the sleeve: width, height, and depth in inches, to the nearest quarter inch.
- Note whether the sleeve top is flat or sloped.
- Photograph the outdoor louver and the empty sleeve with the old chassis pulled.
- Check the sleeve floor for rust. A sound sleeve stays. A rusted-through one changes the plan.

Lead time
Legacy chassis are often built to order. For a building-wide project, order in phases and keep spares on site for winter failures. Units ship from Louisville, Kentucky, or direct from Applied Comfort to anywhere in the New York metro.
