The Lennox SL28XCV central air conditioning unit provides competitive performance in one of the most efficient packages. Its advanced technology earned it a SEER rating of 28, unmatched by any other air-conditioner on the market, according to Lennox, and designated it as one of the Most Efficient ENERGY STAR^® certified products in 2021.

Part of the Ultimate Comfort System™, the air conditioner can combine with other Lennox products like the iComfort^® S30 ultra smart thermostat to create an unprecedented whole-home comfort system that seamlessly and intelligently works together to stay finely tuned to your home and deliver consistently clean, perfect air, according to Lennox.

Using sensors to react, diagnose and troubleshoot issues, the air conditioner also remains in constant communication with the dealer to ensure proactive responses. Geofencing technology ensures air turns on and off as homeowners 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.
