The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) formally petitioned the U.S. Department of Energy (DOE), requesting an 18-month extension for residential non-weatherized gas furnaces from the proposed May 1, 2013 implementation date set for the amended federal minimum efficiency standards. AHRI is requesting the compliance date be delayed until Nov. 1, 2014.
The DOE announced on July 2 that residential HVAC appliances regulated under the pending regional efficiency standards (non-weatherized gas furnaces, mobile home gas furnaces, and non-weatherized oil furnaces) must be installed no later than May 1, 2013. Weatherized gas furnaces, central air conditioners, and heat pumps will follow the same “install by” enforcement ruling, but with a Jan. 1, 2015 compliance date.
