The Most Precise and Efficient Air Conditioner Available
Offering the highest level of performance on the market, the Dave Lennox Signature® Collection SL25KCV air conditioner delivers the ultimate in consistently perfect air for your home. No other air conditioner comes close to its 26.00 SEER2 level of efficiency. From its innovative cabinet design that increases durability, to its digital communication features that maximize accurate control, it is without question the most precise and efficient air conditioner you can buy.
The Perfect Amount of Quiet
To reduce operating sound levels, the SL25KCV uses a sound-dampening system with a precision-balanced, direct-drive fan to ensure smooth, quiet operation. This lets it operate at a volume as quiet as 58 dB, or the sound of a microwave.
Digitally Intelligent for Accuracy and Efficiency
This truly digital product is designed to pair with the Lennox S40 Smart Thermostat as part of a fully communicating home comfort system. Sensors in the equipment allow the thermostat to diagnose issues and automatically make system adjustments to more accurately and efficiently maintain temperature, humidity and air quality.
Cabinets Designed for Reliability and Serviceability
Our most innovative cabinet design features panels that fit securely to the unit to prevent excess noise, along with an easily removable louver panel that allows for quick access by your technician. This proprietary design makes Lennox units more attractive and durable, quieter and easier to install and service, so nothing stands between you and having perfect air in your home.
