AboveAir -Compact 1.5 Ton Thru-The Wall Condensing Unit 35.5" W x 19" H VCU-C-018-1

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-018-1 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)

Not every room needs a big condenser -- and putting in too much capacity is just as bad as too little. The AboveAir VCU-C-018-1 is a 1.5-ton, 18,000 BTU through-wall condenser built specifically for the smaller spaces that make up a huge percentage of NYC apartments: bedrooms, home offices, studios, and junior one-bedrooms in the 400 to 600 square foot range. It's the smallest and most affordable unit in the AboveAir lineup, and it's the right tool for the job when you need dedicated cooling in a room that a 2.0-ton unit would overcool (which leads to short-cycling, humidity problems, and higher electric bills).

What sets the VCU-C-018-1 apart from budget alternatives is the warranty and build quality. You get a 5-year compressor warranty and 2-year parts coverage -- that's better than what most competitors offer at this price point. The cabinet is heavy-duty and water-resistant, which matters when your condenser sits in a wall sleeve exposed to everything NYC weather throws at it. Brass service valves come standard. The 0.25 HP condenser fan motor runs at 1,500 RPM and keeps noise levels manageable, which your neighbors in the next apartment will appreciate.

Like the rest of the AboveAir VCU-C series, this is a split system condenser -- not a packaged terminal unit. It pairs with an indoor air handler connected by refrigerant lines, giving you real cooling performance without the noise and vibration of a PTAC humming inside your bedroom. If you've been dealing with a rattling PTAC that keeps you up at night, moving to a split system is the single biggest quality-of-life upgrade you can make. Our PTAC vs. through-wall comparison breaks down exactly why contractors are steering clients away from packaged terminals.

The unit measures 35.5" W x 19" H and fits standard NYC co-op and condo wall sleeves with zero structural modification. Electrical requirements: 208-230V/1Ph, R-410A refrigerant. Minimum circuit ampacity is 17.75A with a 30A maximum fuse. At roughly 200 lbs, it's a standard two-person install for any licensed NYC HVAC crew. Not sure if 1.5 tons is enough for your space? Our through-wall sizing guide takes about two minutes and factors in ceiling height, window exposure, and floor level -- the variables that actually determine cooling load in a New York apartment.
