The quietest and most efficient single-stage air conditioner you can buy.

Since it offers a SEER efficiency rating of up to 18.50, the SL18XC1 can save you hundreds of dollars per year in energy bills, even through the hottest summers.

Since it’s part of the Dave Lennox Signature® Collection, the SL18XC1 can be easily combined with solar roof modules in a SunSource® Home Energy System. This means it can drastically cut your utility bills and make you eligible for a federal tax credit.

Innovative SilentComfort™ technology combines thick insulation, vibration resistance and a specially shaped fan blade to greatly reduce sound levels.

The condenser coil is the part of the air conditioner that draws hot air from inside your home and releases it outside. The Lennox Quantum™ coil handles the heat like no other. It’s constructed from aluminum alloy, helping it resist corrosion in harsh conditions like coastal environments.

The SL18XC1 is compatible with the advanced control of the iComfort® S30 Smart Thermostat, which delivers unparalleled comfort and connectivity, whether you’re home or away.

Electronic Sensor Technology

The SilentComfort motor built into the SL18XC1 has sensors that provide extremely reliable starting and running performance, no matter the weather conditions.

iComfort-Enabled

Works with the iComfort S30 ultra smart thermostat to adapt cooling settings to match your family's routine.

Ruggedly Engineered

The exclusive Lennox Quantum coil inside the SL18XC1 has an aluminum alloy construction that helps it resists corrosion, even in harsh conditions like coastal environments.
