Stay comfortable all year with the AireVantage USH4BE heat pump and B65 series air handler. This split system cools in summer and heats in winter from one outdoor unit, using a Copeland Scroll compressor and a multi-position microchannel air handler. Built with galvanized cabinets, all aluminum coils, and service friendly access, it is a practical replacement heat pump for homeowners or contractors doing new-construction without a luxury price. Add an electric heat kit when the job needs backup heat on colder nights.

Why homeowners love it

Comfort that actually holds in 95° heat — 14.3 SEER2 so the house gets cold and stays even, without short-cycling or a sky-high power bill.

Quiet enough you forget it’s running — Compressor blanket and swept-wing fan outside, insulated cabinet inside. No roar on the pad and no rattling closet.

Built for outside not a showroom — All-aluminum coils fight formicary corrosion. Outdoor paint passes 950-hour salt spray.

Low-stress ownership — current R-454B refrigerant, built in filter rack, easy to service parts.
