Beyond Quiet

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.

Smarter Together

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.
