Last week, the U.S. Department of Energy proposed a new 92% AFUE standard for residential gas and mobile home furnaces.
These standards would effectively ban the manufacture of non-condensing furnaces starting in 2021. Any stockpiled inventory of non-condensing furnaces manufactured before the compliance date would be legal to install, but supplies would likely quickly run scarce.
The standards would apply nationally and require condensing furnaces for retrofit or new construction. The DOE will accept public comments on the proposal for 90 days and a public meeting is scheduled for March 26, 2015.
