Balanced comfort and efficiency
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.

Keep your old units going..
August 03, 2026I decided to replace my 54 year old AC with a new, more efficient, modern unit and chose a Lennox model. I was told the two stage feature would be great for pulling out the humidity in our house. I have been underwhelmed. My 54 year old equipment did a better job. Since I was informed that all the NEW units last only 12 years on average, maybe manufacturers will prioritize quality by then.
