Always at peak efficiency
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 though the hottest summers.
Solar ready, for the highest possible energy savings
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.
The sound of perfect silence
Innovative SilentComfort™ technology combines thick insulation, vibration resistance, and a specially shaped fan blade to greatly reduce sound levels.
Dependable performance, even in harsh conditions
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.
Enjoy the comfort of connectivity
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.
