Better management of energy usage, temperature and indoor air quality

You'll achieve the highest level of performance and improve comfort and control by combining multiple technologies. The diagram below shows some options, and your Lennox representative can offer other ideas. Please consult our case studies, as well.

When you choose ENERGY STAR® qualified products from Lennox, you'll also control energy usage while creating a superior indoor environment.

L Series® Rooftop Units

These ENERGY STAR units are designed to achieve a low total cost of ownership with capacities up to 30 tons. They are engineered to reduce energy bills, lower the cost of installation and minimize service time. Includes the patented Humiditrol® dehumidification system to control humidity and the spread of allergens.

For additional savings and capacities up to 50 tons, see the S-Class™ rooftop units, for superior comfort and performance.

Demand Control Ventilation

An energy-efficient option for L Series and S-Class rooftop units, it uses a CO2 sensor, the Integrated Modular Controller and gear-driven dampers to control ventilation based on occupancy levels.

Humiditrol Dehumidification System

Uses a patented hot gas reheat design to control humidity independent of cooling needs, while also controlling the spread of allergens. (Available on L Series and S-Class rooftop units)

MERV Filters

MERV 15 filters exceed the minimum requirements set forth by the Leadership in Energy and Environmental Design (LEED), removing a minimum of 85% of particles sized 0.3 to 1.0 micron, including most types of bacteria, paint pigments and smoke. MERV 8, 11 and 15 filters and dirty-filter switches are available as options on S-Class and L Series rooftop units.

L Connection® Network

Provides a single source of contact for complete control of the HVAC system and basic building functions, including signage, lights and fan. This sophisticated system is efficient, easy to install and easy to use, and works with both Lennox and electromechanically controlled third-party HVAC equipment.
