36"W x 19"H 2.0-Ton Thru-Wall Replaces Aerosys TTWC-R24P21, TTWC-R24P21LX, VCU-C-024-1-X, VCU-C-024-1-S

A 2.0-ton thru-wall condensing unit engineered as a direct drop-in for the Aerosys TTWC-R24P21, TTWC-R24P21LX, AboveAir VCU-C-024-1-X, and VCU-C-024-1-S. Specs match point-for-point: standard 36" W x 19" H NYC wall sleeve, 208-230V/1Ph power, R-410A refrigerant, identical physical mounting pattern. If one of those units has gone out in your building, this replaces it without touching the existing sleeve or refrigerant lines.

2.0 tons / 24,000 BTU is the most commonly needed size for NYC apartments — it cools roughly 700 to 1,000 square feet, which covers the typical one-bedroom living room, open-concept loft bedroom, or medium corner studio. Most thru-wall replacements we quote across Manhattan and Brooklyn fall in this tonnage range. For context on whether 2.0 tons is actually right for your apartment — sun exposure, ceiling height, and window size shift the real number — run our through-wall sizing guide.

Build quality is spec’d for NYC conditions: heavy-duty water-resistant cabinet, brass service valves, and a 5-year compressor warranty with 2-year parts coverage. The fan motor is rated at 0.25 HP / 1500 RPM — within the noise profile co-op boards typically accept for exterior-facing units on residential floors. NYC approved for the standard 36" x 19" opening, so straight replacements in existing sleeves generally do not require new DOB filings.

This unit is the practical move when Aerosys or AboveAir 2.0-ton inventory is delayed, which happens routinely between April and July. We keep these in stock specifically for emergency replacements.
