ACCA’s Quality Installation Specification is an ANSI-recognized standard that describes the industry-specified steps a contractor must take to ensure a quality HVAC installation. Developed by a broad coalition of industry stakeholders, the QI Specification identifies consensus requirements associated with quality installations, acceptable procedures for measuring or verifying the attainment of those requirements, and acceptable forms of documentation to show compliance to the requirements. While ACCA currently makes our quality standards available for free download, we retain all rights to the works. They may not be redistributed without our consent.
