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.
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.
With efficiencies of up to 21.00 SEER, the XC21 can lower your energy bills by hundreds of dollars a year, while still keeping your home cool and quiet.
Advanced engineering in the XC21 means enjoying smart, energy-efficient comfort all year long. This product has been designated as one of the Most Efficient ENERGY STAR certified products in 2017. Products that are recognized as the Most Efficient of ENERGY STAR in 2017 prevent greenhouse gas emissions by meeting rigorous energy efficiency performance levels set by the U.S. Environmental Protection Agency.
Because it’s solar ready, the XC21 can be easily combined with solar roof modules in a SunSource® Home Energy System. This means it can use free energy from the sun to keep your home cool.
