The public has another chance to give their opinions on a proposed American National Standards Institute HVAC construction standard written by the ACCA.

The Air Conditioning Contractors of America announced that its revised “HVAC Quality Installation Specification” opened for review Friday and will be available for comment through May 31.

The HVAC market standard covers the minimum requirements for installation of HVAC construction systems in residential and commercial situations. Changes from the last public review have been put into the new proposed standard.
