ARLINGTON, Va. - The Air Conditioning Contractors of America (ACCA) has made four of its ANSI-recognized standards available for free electronic download. The four standards available for download are:

• ANSI/ACCA 5 QI – 2010 HVAC Quality Installation Specification, which 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.

• The recently revised ANSI/ACCA 9 QIvp – 2011 HVAC Quality Installation Verification Protocols, which are for those who intend to protect the value and integrity of the QI Standard through qualified and objective examination of submitted HVAC system installations.

• ANSI/ACCA 4 Maintenance of Residential HVAC Systems – 2008, which provides a common platform for contractors to create a maintenance program, while allowing for bundling different recommended corrective actions at different fee structures.

• ANSI/ACCA 6 HVAC System Cleanliness – 2007, which is intended for restoring the cleanliness of HVAC systems. The procedures are also designed to reduce an adverse effect on the indoor environment and other building systems.

“Making the standards freely available to interested stakeholders - contractors, whole-building practitioners, OEMs, utilities, Energy Star participants, customers, etc. - will spread the word as to what is considered quality when it comes to HVAC systems and what needs to be expected from all installations,” said Joe Nichter, ACCA chairman of the board.

The QI standard and the QIvp standard are also the foundation of the Quality Assured (QA) Contractor recognition program. The QA program is required for contractors who install HVAC systems in new homes that are intended for Energy Star rating and are finished Jan. 1, 2012 or after.
