This 4th Generation system is perfect for homes, garages, workshops, or commercial spaces where efficient, customizable heating and cooling is needed—without the complexity of ductwork or professional installation.

Powerful Multi-Zone Climate Control

At its heart is a robust 48,000 BTU condenser that supports three zones, each managed by sleek ceiling cassette air handlers. The system includes one 12,000 BTU unit ideal for spaces between 376 and 500 square feet and two 18,000 BTU units designed for larger rooms from 501 to 750 square feet. This combination delivers tailored, whisper-quiet comfort across a variety of room sizes.

Effortless, Technician-Free Installation

This design empowers you to install the system yourself quickly and confidently, saving on labor costs and avoiding the hassle of scheduling professional service.
