Mid-efficiency, two-stage air conditioner
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.
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.
The Standard of Operation
A single-stage unit is either on or off, working at full capacity when in use. With this simplified mode of operation, this product provides the heating and cooling levels you’d expect.
