“Regionalizing heating and cooling efficiency standards would eliminate the largest markets for the most affordable equipment, causing immediate cost increases for those states whose standards might not even change at all,” according to Talbot Gee, vice president of HARDI. “Homeowners … will have no choice but to repair and maintain older, less-efficient systems rather than replacing them with high-efficiency systems that they could no longer afford.”
Gee noted that the regionalization strategy does not introduce any equipment that is not already available.
