The Air Conditioning Contractors of America is continuing to ask senators to fix a bill encouraging the purchase of energy-efficient products before passing the legislation.

ACCA officials say the U.S. House-passed version of “Home Star” deals with only some of their issues.

"We are certainly supportive of the goals of this legislation - to make American homes more energy efficient and provide much-needed jobs in the construction industry," said John Sedine, ACCA chairman and president of Engineered Heating and Cooling in Michigan.

The association recently sent a letter to the Senate finance and natural resources committees outlining their concerns.

"Unfortunately, certain provisions in this legislation make the achievement of these goals actually less likely," Sedine said.

The $6 billion proposal to improve the energy efficiency of U.S. homes was announced in March by President Barack Obama. Named “Home Star” after the popular Energy Star efficiency-certification program, it would offer point-of-sale consumer rebates for the purchase of energy-saving products. Contractors, home improvement stores and utility companies would market the program. Rebates would come from the federal government.

Some construction groups, such as the ACCA, have expressed opposition to the proposed reimbursement mechanism.
