Model L rooftop units deliver the lowest total cost of ownership through variable-speed components and intelligent operation.
The Lennox® CORE Control System delivers connected service, open integration, reliable performance, and efficiency optimization to empower all parts of your organization.
Advanced technologies deliver premium comfort and indoor air quality in a wide range of applications.
Model L rooftop units maximize the efficiency of maintenance and service operations, reducing operational costs and minimizing downtime.
Model L units feature a lead variable-speed compressor and variable-speed blower to maintain a constant discharge air and room temperature to efficiently deliver complete comfort.
Humiditrol+ is a modulating hot-gas reheat dehumidification system that can vary the sensible and latent capacity of the Model L unit to better match the dehumidification demand of the space.
ENHANCED DEHUMIDIFICATION MODE
Model L units are enabled with enhanced dehumidification (EDH) mode, which is designed to provide additional dehumidification when both cooling and dehumidification demands are present.
3-12.5-ton Model L units are equipped with a direct-drive, variable-speed blower that eliminates maintenance and service costs associated with traditional belt-drive motors.

Needlepoint Bipolar Ionization (NPBI) Kit
NPBI technology integrates with system controls for effective air treatment Ionization has been shown to effectively reduce harmful pathogens, pollutants, and odors. Brush-type ionizer introduces a high concentration of both positive and negative ions into the air stream
Healthy Climate® UVC Germicidal Lamps
Germicidal lamps emit ultra-violet (UV-C) energy, which has been proven to be effective in reducing microbes such as viruses, bacteria, yeasts, and molds. This process either destroys the organism or controls its ability to reproduce
