DES PLAINES, Ill. — RSES has partnered with Air Conditioning Contractors of America (ACCA) to offer American National Standards Institute- (ANSI) recognized quality standards to its members. The two standards include ANSI/ACCA 4 QM – 2007 (Maintenance of Residential HVAC Systems) and ANSI/ACCA 6 HVAC System Cleanliness – 2007 (Restoring the Cleanliness of HVAC Systems).

RSES has partnered with ACCA in an effort to improve the skills of those selecting and installing HVAC equipment to make certain quality installations are being performed. According to RSES, this ongoing partnership with ACCA provides RSES members yet more value for their annual dues, while contributing toward the broader distribution of established HVAC system quality standards.

Mark Lowry, RSES executive vice president said, “Providing these two standards continues the process begun last year to keep our members abreast of industry developments, especially as the standards are increasingly referenced within regulations and legislation. We are committed to helping RSES members lead the industry in installation, maintenance, and restoration of systems.”

According to ACCA, the maintenance of residential HVAC systems details necessary inspection and maintenance for residential HVAC systems. The standard includes a series of checklists for varied types of residential HVAC systems, that specify minimum tasks to be performed and recommend corrective actions if deficiencies are found. Contractors may use this standard to demonstrate minimum maintenance requirements and the need to perform certain servicing tasks. The checklists also allow contractors to highlight added services offered in maintenance and service contracts.

The Restoring Cleanliness of HVAC Systems establishes the minimum criteria for cleaning HVAC systems, triggered as a matter of routine maintenance or following some contamination event. The standard provides guidelines for determining whether cleaning is warranted and economically viable, along with a protocol for cleaning each relevant component or subsystem as well as verification procedures. In addition, a helpful appendix outlining routine maintenance, inspection, and cleaning procedures is included.

RSES members may download the two standards as well as two quality installation standards from at no charge by logging into the site and selecting “My RSES Home Page” and “ANSI/ACCA Q Standards” under the “My RSES” section.
