It’s recently come to our attention that some furnace manufactures have discontinued having their units ENERGY STAR-qualified. This poses some concern for homes enrolled in the ENERGY STAR for New Homes (ESNH) program, as an ENERGY STAR-qualified furnace may be required for certification.
Here’s a summary of the ESNH requirements for furnaces:
ESNH – version 2011 (which will end in November 2014)
Min efficiency 92% AFUE ENERGY STAR-qualified, and
ECM motors qualify for an Electrical Savings Credit
ESNH – version 12 (known as the 2012 version)
Min efficiency 95% AFUE and either:
1) ENERGY STAR-qualified, or
2) With furnace fan efficiency ≤ 2.0%
ENERGY STAR-qualified furnaces are listed on this website:
(NB: this is a US website, so be sure to check off the ‘Canadian’ options.)
