Precise Comfort® technology adjusts cooling output in precise and minute increments to perfectly match your energy use with your comfort.
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 2022. Products that are recognized as the Most Efficient of ENERGY STAR in 2022 prevent greenhouse gas emissions by meeting rigorous energy efficiency performance levels set by the U.S. Environmental Protection Agency.
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.
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.
With the help of the iComfort® S30 ultra smart thermostat, the SL28XCV air conditioner unlocks a world of connectivity. It stays finely tuned to your home by using sensors to react, diagnose, and troubleshoot—all while remaining in constant contact with your dealer to ensure proactive responses. Geofencing technology ensures your air turns on and off as you come and go. And the system even responds to the outdoor environment to adjust operation to account for factors like pollen and outdoor air quality.
