January 2013 UPDATE: High Efficiency
Furnace Regulations POSTPONED
Effective May 2013 for New Furnaces Only
Congress has passed a Bill requiring any new furnaces purchased and installed after April, 2013, to be high efficiency. The 2013 high efficiency regulations document lists specific information that clarifies this legislation.
For anyone seeking to replace their unit soon, you might wish to do so before May 1, 2013 to avoid additional costs associated with necessary additional piping and venting to the exterior of your unit. New installations require a Property Modification Form and Board approval.
