Contractors also want to be sure that the sys-tems they are selling perform as advertised, which is why manufacturers usually rely on an unbiased third-party verifier, such as the Air-Conditioning, Heating, and Refrigera-tion Institute (AHRI), to independently mea-sure the performance — or energy efficiency — of their HVAC equipment. Most in the industry are already familiar with many of the terms used to describe the energy efficiency of a unit — SEER, AFUE, EER, COP, etc. But other measurements are starting to be used as well, such as CEF, IEER, SCHE, and SCOP, which have been developed by AHRI, the U.S. Department of Energy (DOE), U.S. Environmental Protec-tion Agency (EPA), and other groups. Manu-facturers say these terms are useful to know when determining the amount of energy used by certain systems. Heat Pump Ratings The appropriate rating acronym depends on the type of system that is being considered. For residential gas furnaces, one term is typi-cally used in all instances: AFUE, which stands for annual fuel utilization efficiency. AFUE is a measure of how efficient the furnace is in • See RATINGS | page 7 Heat pumps have several energy efficiency ratings that can be used to describe their performance, such as the 22 SEER, 10 HSPF iQ Drive heat pump shown here.

Continued on page 4 he U.S. Environmental Protec-tion Agency (EPA) has proposed a final timeline for the phaseout in production of virgin hydrochloro-fluorocarbon (HCFC)-22. The proposal picks up on a previous timeline in production that allowed 62.8 million pounds of new R-22 in 2013 and 51 million pounds in 2014. What the EPA is calling its “preferred HCFC-22 consumption allocation for 2015-2019” shows an allowance of 30 million pounds in 2015, 24 million pounds in 2016, 18 million pounds in 2017, 12 million pounds in 2018, 6 million pounds • See R-22 | page 14 PODCASTS NEWS you can listen to for the latest NEWSUpdates and lively interviews.
