1-1/2 TON THRU-THE-WALL AIR CONDITIONER, 12 SEER 208-230/60/1 R-410A

A reliable workhorse for NYC co-op and condo owners looking for the simplest possible thru-wall installation: one unit, one sleeve, cooling done. This 1.5-ton packaged thru-wall air conditioner delivers 18,000 BTU through the standard 36" x 19" wall opening that has been the NYC building standard since the 1960s — no separate indoor air handler, no refrigerant line routing through finished walls, no second piece of equipment to maintain. Slide it in, wire it up, done.

At 12 SEER, this unit meets federal efficiency standards for its class and is sized for bedrooms, studios, and smaller one-bedrooms in the 400 to 600 square foot range. It is the right pick when you want straightforward cooling without the complexity of a split system. If you are trying to decide between a packaged thru-wall unit like this one and a split system condenser, our PTAC vs. through-wall guide covers the tradeoffs in plain English — performance, noise, lifespan, and installation cost.

The unit operates on 208-230V/60Hz/1Ph power and uses R-410A refrigerant. Because this is a packaged design — compressor, coils, fan, and blower all housed in one cabinet — there are no refrigerant lines to leak, no indoor coil to service, and no separate blower motor to fail. That simplicity is why some building engineers still spec packaged thru-wall units for buildings where apartment-by-apartment service access is a headache. One truck roll, one technician, in and out.

NYC-specific note: this unit fits standard wall sleeves in co-ops across Manhattan, Brooklyn, and Queens — no structural modifications required for a straight replacement. If you are not sure whether 1.5 tons is the right capacity for your space, run through our sizing guide before ordering. Sun exposure, floor height, and window count matter more than raw square footage. For current stock or building-wide pricing, call us at (385) 319-1559.
