The Lennox XC21 is a multi-stage air conditioner. It is considered the quietest and most efficient two-stage central air conditioner you can buy! The XC21’s multi-stage operation allows it to fine-tune your cooling, humidity levels and energy use by matching output to demand. By working with the Humiditrol® whole-home dehumidification system, the XC21 can preserve your comfort in every way. With efficiencies of up to 21.00 SEER, it can also lower your energy bills by hundreds of dollars a year. This product has been designated as one of the Most Efficient ENERGY STAR certified products in 2017.
