Comfort and efficiency come together perfectly

The XC21’s multi-stage operation allows it to fine-tune your cooling, humidity levels and energy use by matching output to demand.

Cooling that goes beyond temperature control

Humidity levels can drastically affect how the air in your home feels. It can make the air feel up to 8 degrees warmer than the actual temperature. By working with the Humiditrol® whole-home dehumidification system, the XC21 can preserve your comfort in every way.
