Low Profile – F Series

View More Air Handlers
Overview

A compact, efficient solution that’s perfect for single or multi-family use, the F Series air handler is designed to meet the industry’s new energy efficiency standards. The F Series is now offered with a 240 V or 120 V 5-speed ECM motor, to meet any electrical application need. The new 120 V 5-speed ECM means there’s no need for a 240 V circuit, saving time and money when a traditional AC system is being replaced with a heat pump while helping systems meet rebate or tax credit efficiency. This 120 V unit is meant for mild climate applications where electric heat isn’t a requirement.
