The US Dept of Energy (DOE) announced in April it will not enforce its rule requiring the most common type of residential gas furnaces to adhere to a minimum 90 AFUE (high efficiency) standard beginning May 1, 2013.
The American Public Gas Association (APGA) filed a lawsuit against DOE regarding this high efficiency standard for the Northern region of the US (cold climate zones). A settlement agreement between APFA and DOE has yet to be ruled on by the court, meaning the 90 AFUE standard could be enforced. However, DOE announced it would not do so on April 5.
The heating and cooling contractor industry is generally opposed to energy efficiency mandates — see HVACR News and ACCA’s website. They fail to understand the importance of energy efficiency for our children’s future on the planet.
