Product Description
The Cooper & Hunter 18,000 BTU (1.5 Ton) multi-position air handler is a single-zone ducted mini split heat pump system on next-generation R454B refrigerant — a true central-style AHU that connects to your ductwork and installs in any of four orientations: upflow, downflow, horizontal left, or horizontal right. With a 18.5 SEER2 inverter system on 208/230V and adjustable static pressure up to 0.8 in.WG, it serves whole homes and large zones up to approximately 1,000 sq ft and keeps heating in outdoor temperatures as low as -13°F — still delivering 13,000 Btu/h of heat at 5°F.
