The U.S. Department of Energy’s Office of Enforcement issued a Notice of Noncompliance Determination (Notice) on September 27, 2011, to AeroSys, Inc. (AeroSys) regarding four models of central (through-the-wall) air conditioners that fail to meet Federal energy efficiency requirements.
DOE tests revealed that AeroSys through-the-wall air conditioner models THDC-18S, THDC-18T, THDC-24S, and THDC-24T do not meet the minimum energy efficiency requirements set forth in DOE regulations. The Notice provides that AeroSys must inform those to whom it has sold the models that they do not meet the applicable standard and must offer to buy back, replace, or repair any noncompliant units. These R-22 air conditioners were subject to a 10.9 SEER standard. This type of air conditioner became subject to a 12.0 SEER standard on January 23, 2010.
