NCPE4184010 1.5 TON THRU-THE-WALL SPLIT SYSTEM CONDENSING UNIT

Buildings that are replacing thru-the-wall units in bulk -- 10, 20, sometimes 50+ apartments at once -- need a unit that balances performance, efficiency, and cost. The NCPE4184010 from National Comfort Products hits that sweet spot. It's a 1.5-ton split system condenser rated at 14 SEER, which is meaningfully more efficient than the base 12 SEER models still common in the NYC market. Over the life of the unit, that efficiency gap translates into real savings on electricity bills, especially in south-facing apartments that run AC hard from June through September.

This condenser delivers 18,000 BTU of cooling through a standard 36\" W x 19\" H wall sleeve -- the same opening your building already has. It runs on 208-230V/60Hz/1Ph and uses R-410A refrigerant. Like all NCP thru-the-wall units, it's the outdoor half of a split system: it mounts through the wall and connects to an indoor air handler via refrigerant lines. The result is quieter operation and better temperature control than any packaged terminal unit can offer, because the compressor noise stays outside where it belongs.

At $8,934, the NCPE4184010 comes in slightly below the NCP418000B while delivering the same 18,000 BTU capacity with a higher efficiency rating. That makes it a strong pick for co-op boards and property managers who are shopping on value -- you're getting more efficient cooling for less money per unit. When you're outfitting an entire building, those per-unit savings compound fast. If your building is also exploring modern air distribution approaches, take a look at our fan wall retrofit guide to see how newer air handler designs pair with condensers like this one.

NCP has deep roots in the New York City HVAC world. Their units are spec'd by building engineers who've been working these systems for decades and want equipment they can trust. The NCPE4184010 ships with a full spec sheet (available on the product page) so your installer can verify compatibility before ordering. Not sure if 1.5 tons is the right size? Our through-wall sizing guide walks you through the calculation in about two minutes, factoring in the things that matter most in NYC apartments: ceiling height, window exposure, and whether you're on a top floor baking under the roof.
