28 SEER is the new standard
This premier air conditioner delivers an efficiency rating of up to 28 SEER—no other air conditioner comes close to this level of efficiency. It’s truly the very top of top-tier.
This air conditioner has also been designated as one of the Most Efficient ENERGY STAR® certified products in 2021. Products that are recognized as the Most Efficient of ENERGY STAR in 2021 prevent greenhouse gas emissions by meeting rigorous energy efficiency performance levels set by the U.S. Environmental Protection Agency.
Beyond Quiet
This air conditioner has been engineered with a variable-capacity compressor which allows it to primarily run in low speed—drastically minimizing the sound of air kicking on or off inside the home. Add in a special sound-dampening system to absorb outdoor noise and you can be assured it operates at a noise level that is, quite simply, unheard of.
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.
Just the right amount of airflow
The SL28XCV Air Conditioner is the finest air conditioner Lennox makes, and one of the main components of the Ultimate Comfort System™.
