Overview of the SL18XC1

The Lennox SL18XC1 is a single-stage, Energy Star certified air conditioner with an efficiency rating of up to 18.50 SEER. It is part of the Dave Lennox Signature Collection and uses SilentComfort technology, which combines thick insulation, a specially designed fan blade and vibration resistance to provide sound levels as low as 65 decibels. It is iComfort-enabled, allowing the SL18XC1 to share information and make adjustments from home or remotely when combined with an iComfort thermostat. The unit features a corrosion-resistant Lennox Quantum coil constructed of aluminum alloy, and 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 protect the unit against rust and corrosion. The SL18XC1 is solar-ready and can be combined with solar roof panels to save energy.
