AboveAir - Compact 2.5 Ton Thru-The Wall Condensing Unit 35.5" W x 19" H VCU-C-030-1

Discontinued: AboveAir no longer builds through-the-wall equipment. AboveAir Technologies is still in business, but the company has moved to mission-critical precision cooling and the VCU line is gone from its catalog. The VCU-C-030-1 cannot be ordered new. It used the same 36" x 19" NYC sleeve opening as the Aerosys P Series, and no manufacturer builds for that opening today, so we have ours custom fabricated to drop into the sleeve you already have. R-454B instead of the phased-out R-410A, lead time 14 to 21 days, built to order. See the AboveAir VCU replacement cross-reference for the full model-by-model list.

About this unit (for identification)

At 30,000 BTU, the AboveAir VCU-C-030-1 is the biggest through-wall condenser you can drop into a standard NYC wall sleeve -- and right now it's one of the best values in the lineup. Priced lower than the 2.0-ton VCU-C-024-1, this 2.5-ton unit gives you more cooling for less money, which makes it worth a serious look if your space can handle the capacity. We're talking large open-plan lofts, combined living and dining areas, and pre-war apartments with high ceilings where heat load runs higher than the square footage suggests. Expect solid coverage in the 1,000 to 1,400 square foot range.

This is also a strong pick for light commercial applications -- small retail spaces, ground-floor offices, and storefront businesses across the five boroughs. If you're managing a mixed-use building and need a single unit that handles a larger zone without ducted complexity, the VCU-C-030-1 delivers. For building managers weighing through-wall options for commercial spaces, our commercial HVAC guide covers the key considerations around capacity planning and code requirements.

Like every AboveAir VCU-C series unit, this is a split system condenser that pairs with an indoor air handler via refrigerant lines. You get the quiet, high-performance cooling of a real split system instead of the noise and limitations of a packaged terminal. The unit fits the standard 35.5" W x 19" H sleeve opening found in NYC co-ops and condos built from the 1960s forward -- no structural modification, no sleeve swap, no DOB permits for a straight replacement. Runs on 208-230V/60Hz/1Ph with R-410A refrigerant.

The VCU-C-030-1 is especially relevant for buildings exploring fan wall retrofit projects, where higher-capacity condensers serve multiple zones through a centralized air handler setup. If you're not sure whether 2.5 tons is right for your space or whether you'd be better served by the smaller 2.0-ton model, run through our through-wall sizing guide -- it accounts for ceiling height, sun exposure, and the other variables that actually matter in New York buildings.
