18 SEER

Quiet Operation
TThe Allegiance 18 is the ultimate investment in your family’s home comfort. The America Standard Allegiance 18 provides the ultimate comfort with the quietest operation and highest efficiency. It’s so quiet; you may not even know its running. The American Standard Allegiance 18 is designed to work as quietly as possible, regardless of the weather or the comfort level you wish to maintain in your home. This is because of their innovative variable speed fan motor, which operates at a very low rpm. Even on the hottest summer days when it operates at higher speed, it does so with significantly reduced rpm, giving you the kind of quiet operation you’d expect from an Allegiance 18.

Two Compressors Are Better Than One
Two-staged cooling means exactly what you think it does. Instead of operating on one single-speed compressor, an Allegiance 18 operates on two dual duration compressors which provides two-stage cooling. Most of the time the system will operate at low speed the first stage compressor. This provides quiet even comfort in your home. The first stage is also extremely efficient giving you increased energy savings. However on extremely hot days when the cooling demand is higher, it switches to the second stage to make sure your home’s comfort is maintained. Two stage cooling puts an end to temperature swings. Since it operates at low speed most of the time, cool, conditioned air is distributed consistently and evenly throughout your home for the ultimate level of comfort. With a SEER of 18.90, the Allegiance 18 well exceeds the minimum efficiency level of 13.00 SEER designated by the EPA for Energy Star recognition.

Greater Humidity Control
When matched with a American Standard variable speed furnace or air handler, an Allegiance 18 air conditioner has a special feature called comfort-R. Set by the installer, Comfort-R is a method of ramping airflow so it gets cooler faster, so your comfort is attained much sooner. Comfort-R dehumidifies your home, removing up to 24 gallons of water a day compared to only 6 gallons that a non-variable speed system removes.
