Air Conditioner Quietest, Most Efficient Yet
Rated up to an unprecedented 20.5 SEER (Seasonal Energy Efficiency Rating), Lennox’s new XC21 residential central air conditioner is the quietest and most efficient on the market today, according to the manufacturer’s published ratings. A division of Lennox International, Inc., Lennox is a member of the National Council of the Housing Industry — the Supplier 100 of NAHB. The XC21 has been engineered for quiet performance, and is approximately 13 times quieter than a standard air conditioner, Lennox says. A patent-pending fan design, two-stage operation and an insulated compressor also help hold the sound it makes to a minimum. The XC21 features a two-stage scroll compressor with two levels of operation: high for hotter summer days and low for milder temperatures. The low setting is adequate to meet household cooling demands up to 80% of the time. A high-efficiency outdoor coil provides exceptional heat transfer and low air resistance for more efficient operation. The air conditioner also features the Lennox System Operations Monitor, which continually monitors system performance, helping technicians solve problems faster and more accurately. For added peace of mind, the monitor can communicate with select thermostats to indicate when service is needed. XC21 is an Energy Star product that meets the efficiency standards of the Environmental Protection Agency. It uses chlorine-free R410A refrigerant, which meets the EPA’s most stringent guidelines for ozone and environmental safety. XC21 is nearly twice as efficient as a typical air conditioner and can help lower utility bills significantly. This feature is solely for educational and informational purposes.
