The quietest and most efficient two-stage central air conditioner you can buy.
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.
An energy-smart decision you’ll appreciate every day
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.
Leading the way in smart energy use
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 2018. Products that are recognized as the Most Efficient of ENERGY STAR in 2018 prevent greenhouse gas emissions by meeting rigorous energy efficiency performance levels set by the U.S. Environmental Protection Agency.
You’ll hardly know it’s running
The XC21 uses SilentComfort™ technology to reduce operating noise, making it the quietest multi-stage air conditioner you can buy. Even when installed outside a bedroom window, it lets you rest peacefully.
Smarter solutions from the sun
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.
