Luxaire® Optimum™ Core is the go-to unit for 3-12.5 ton jobs. With competitive efficiency up to 17.2 SEER/13.2 EER/ 16.3 IEER, Core rooftop units have the commercial options available to meet customer needs in both new construction and retrofit applications. Fits most of the installed market, avoiding the need for costly transition curbs.

The lightweight design of high-efficiency Optimum™ Choice rooftop units is up to 33% lighter than existing Luxaire® models (and up to 22% lighter than competing products), further streamlining specification by saving on building design requirements and eliminating the need for additional structural engineering analysis when used in replacement applications. In addition, the full range of Optimum™ Choice rooftop units have been designed to fit approximately 70% of the competitive installed base, minimizing the need for costly transition curbs.

Optimum™ Select rooftop units offer an industry-leading choice of three distinct airflow options within the base product model: 2-stage with IntelliSpeed™ fan control, 4-stage variable air volume and 4-stage with IntelliSpeed™ fan control. Select rooftop units also share the same footprint as competitive units installed in the field, minimizing the need for costly, leak-prone and unattractive transition curbs.
