SL25KCV
Air Conditioner
The most precise and efficient air conditioner available.
Precision Makes Perfect
Precise Comfort® technology finely-tunes and adjusts cooling output in tiny increments, perfectly matching your energy use with your comfort, making it the highest-efficiency, variable-capacity air conditioner available.
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.
Sound-dampening system ensures smooth, quiet operation for a more peaceful environment.
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.
A fully digital product for more accurate and efficient performance.
