Introduction
Welcome to the Lennox® standard of excellence. The Merit® Series raises the bar for heating and cooling across the industry. Don't settle when it comes to the air around you – ask for more. Ask for Merit.
Quiet and Efficient Operation
The Lennox Merit® Series Split Systems offer quiet and efficient operation, featuring:
- 1. Outdoor Coil Fan: Moves large volumes of air uniformly through the entire condenser coil for high system efficiency.
- 2. Quantum Coil: Made from proprietary aluminum alloy for corrosion resistance, improved performance, and energy savings.
- 3. Scroll Compressor: Provides smooth, efficient, and quiet operation.
- 4. Heavy Gauge Steel Cabinet: Built using superior materials and proprietary designs make Lennox® units more durable, safer, and easier to install.
- 5. Braze Free Refrigerant Line Connections: Connections and service valves are in one central area of the cabinet for easy access and simple installation.

Quantum Coil, constructed from a proprietary aluminum alloy for enhanced corrosion resistance and efficiency. 3. Scroll Compressor, designed for smooth, quiet, and efficient operation. 4. Heavy Gauge Steel Cabinet, built with durable materials. 5. Braze Free Refrigerant Line Connections and service valves, located centrally for easy access.
Quantum Coil Technology
With years of rigorous testing under the most extreme conditions, the Quantum Coil – featuring a proprietary aluminum alloy exclusive to Lennox – is designed to weather the harshest elements. Our exclusive coil is made for improved resistance to corrosion, resulting in improved performance and energy savings.
Improved Humidity Control
Humidity is harder to control on mild-temperature days, when less cooling is needed. The ML17KC2 unit was designed to remove more moisture than many other systems by shifting to a lower-capacity stage on mild days to match the heat load, then running long enough to reduce both temperature and humidity. To enhance humidity control even further, choose the optional Humiditrol® dehumidification system. The patented dehumidification system controls temperature and humidity independently, reducing moisture and helping curb the spread of mold and other airborne contaminants.
