Lennox XC20 Central Air Conditioner Overview

The Lennox XC20 is a variable-capacity air conditioner with an efficiency rating of up to 20 SEER. It was named an Energy Star Most Efficient 2016 product. The unit’s variable-capacity scroll compressor adjusts cooling output in small increments and combines with a precision-balanced direct drive fan to help keep operating sound levels as low as 65 decibels. The XC20 is iComfort-enabled, allowing it to provide optimal humidity control, share information and make adjustments from home or remotely when combined with an iComfort thermostat. The XC20 features a SmartHinge louver design which improves service capability by allowing easy access to internal components from all sides. A heavy gauge galvanized steel cabinet with baked-on powder finish and zinc-coated steel base protects the unit against rust and corrosion.
