The AireVantage 3.5 Ton 14.3 SEER2 Air Conditioner Split System with R-454B Refrigerant (USA4BE5M1SN42K-B65BMMX42K-C) is a matched residential split-system air conditioner designed for reliable cooling performance. The system combines the USA4BE5M1SN42K outdoor condenser with the B65BMMX42K-C multi-position air handler. The published matched-system data rates this combination at 41,000 BTU cooling capacity at 95°F, 11.7 EER2, and 14.3 SEER2.

The outdoor condenser uses a Copeland Scroll compressor, PSC condenser fan motor, all-aluminum coil, high-pressure switch, and included liquid-line filter drier. The indoor air handler features a multi-position design, three-speed PSC blower motor, microchannel coil, and R-454B TXV/TEV metering device.
