Survey: HVAC contractors unprepared for 2015 efficiency standards
St. Louis -- A majority (74%) of U.S. contractors are unaware of upcoming 2015 regional standards for unitary air conditioning and heat pump systems, according to a survey by Emerson Climate Technologies Inc. Nearly 80% of contractors were unaware of 2015 part-load efficiency requirements for light commercial split, package and rooftop systems, and 84% are unaware of the 2015 chiller standards. Unlike the 2005 regulation changes, the 2015 changes will affect both residential and commercial efficiency standards.
