"This is a very important step," said Merrian Borgeson, director of California climate and clean energy at Natural Resources Defense Council. "The CEC knows that it doesn't make sense anymore to install only A/C. This gets heat pumps out en masse and gives people the option to turn off their gas furnace, or just get off it entirely."
The draft regulation doesn't outright ban traditional air conditioning units or require homeowners to remove their gas furnaces when a unit breaks. Instead, they require a contractor to either install a heat pump or make additional efficiency improvements to the A/C unit spelled out in the regulation.
