Features

Balanced comfort and efficiency

While most air conditioners are single stage, meaning they're either on or off, this air conditioner can heat or cool at two different speeds. Most of the time the unit will meet cooling needs at its lower speed, resulting in balanced and consistent temperatures with lower energy use.

Efficient and Affordable

The ML17KC2 offers energy efficiencies of up to 18.00 SEER2, delivering comfort and energy savings at a more affordable price.

Our Uncontested Quantum™ Coil

With years of rigorous testing under the most extreme conditions, our Quantum Coil – featuring a proprietary aluminum alloy exclusive to Lennox – is designed to weather the harshest elements.

A refrigerant that’s better for the environment.

This product is compliant with 2025 EPA regulations for lower global warming potential (GWP) refrigerants. The Lennox choice of 2025 Compliant Refrigerant has a lower GWP than its predecessor and is formulated to provide excellent, reliable performance of your system for years to come.

4-Ton 2-Stage

4 ton, 2-Stage offers great function at a reasonable price. It’s been running perfectly everyday since installed 5/30. It saved our Summer with many guests visiting; we didn’t worry about their comfort.
