Economical, environmentally responsible home cooling
The Lennox EL18KCV Elite Series is a variable-capacity central air conditioner known for its quiet and energy-efficient operation. It uses a variable-speed compressor to precisely adjust its cooling output, providing improved temperature and humidity control compared to single-stage units. Even in the hottest summer months, the EL18KCV works efficiently to enhance your comfort.
Key Features
- Variable-capacity compressor: This technology allows the unit to adjust its cooling output in small increments, helping to maintain a more consistent temperature and control humidity.
- High energy efficiency: With a Seasonal Energy Efficiency Ratio 2 (SEER2) rating of up to 19.5, the EL18KCV exceeds efficiency standards.
- Quiet operation: The unit features a sound-dampening system with a precision-balanced, direct-drive fan, allowing it to operate at sound levels as low as 67 dB.
- Durable construction: The EL18KCV has a heavy-gauge, galvanized steel cabinet with a baked-on powder finish and a proprietary aluminum alloy Quantum™ Coil, which is designed to withstand harsh elements and resist corrosion.
- ENERGY STAR® certification—Efficiency rating up to 19.5 SEER2, which can save you hundreds of dollars a year, compared to a standard air conditioner. Ask about seasonal rebates.
- Superior humidity control: Because the unit can run for longer, continuous cycles at lower capacity, it is exceptionally effective at removing moisture from the air. This improves indoor comfort and can help prevent mold growth.
- Environmentally friendly: The EL18KCV is compliant with 2025 EPA regulations and uses R-454B refrigerant, which has a lower global warming potential (GWP) than older refrigerants.
Technology and Reliability
- Digital-ready integration: When paired with a compatible smart thermostat, such as the Lennox S40, the EL18KCV becomes part of a fully communicating home comfort system. This allows the system to exchange data and automatically configure itself for maximum efficiency.
- Quantum™ coil: This exclusive, proprietary aluminum alloy coil is designed to resist corrosion and withstand harsh elements, extending the life of the unit.
- Durable cabinet construction: A heavy-gauge, galvanized steel cabinet with a baked-on powder finish provides long-lasting protection against rust and corrosion. Hinged steel louver panels also offer easy access for service and cleaning
- Lennox Elite™ Warranty: All Elite models come with a 10-Year Limited Warranty on compressors and a 5-Year Limited Warranty on covered components. A 10-Year Extended Limited Warranty is available with product registration.
