A two-step Duration Compressor; Super Efficiency up to 17.00 SEER / 9.20 HSPF; Attractive soft gray color; Recessed fan grille; Powder-painted louvered cabinet; Spine Fin aluminum coil; Greater humidity control; Single-sided service access.

As an Energy Star® Partner, American Standard has determined that some models meet the Energy Star® guidelines for energy efficiency.


Energy Star® qualified. The Allegiance® 16 well exceeds the minimum efficiency level of 13.00 SEER designated by the EPA for Energy Star® recognition:

  1. Spine Fin coil is constructed of thousands of tiny spines bonded to continuous all-aluminum refreigerant tubing, which provides more surface area, adding greater heat transfer capabilities and more effectiveness over time.
  2. Variable speed fan motor operates very quietly so noise levels are kept at a minimum. And, it conserves energy for lower cost operation.
  3. Steel louvered panels are designed to protect the coil from leaves, hail and damaging elements.
  4. Baked-on paint coating on the louvers won’t scratch and prevents rust and corrosion.
  5. Durabase basepan is made from a durable composite material that won’t crack, warp, corrode or rust.
  6. Easy-Sess service access panels protect all electrical and refreigerant controls with a side panel that can be quickly removed for installation or service.
  7. Duration compressor is the heart of the system. With an oversized, heavy steel outer shell, an epoxy-sealed heavy duty motor, and a unique valve design, our compressor will stand up to the harshest elements for years to come.
  8. SermaGuard rust resistant screws resist against rust and corrosion.
  9. compressor sound insulators reduce noise for quieter operation. (Some models.)
