ARLINGTON, Va. — ACCA announced the release of the 2019 Quality Maintenance Standard: ANSI/ACCA 4QM – 2019 Maintenance of Residential Systems.  

“ACCA is proud to lead the industry by creating these technical standards that provide contractors with a template to create their own maintenance programs,” said ACCA president and CEO, Barton James. “For more than fifty years ACCA has been recognized as the industry’s standard provider. ACCA undergoes a vigorous approval process that includes contractor, manufacturer, and partner involvement to reach consensus for ACCA standards, and ACCA proudly leads these contractor-driven efforts that increase professionalism in the industry.”

“ACCA members usually provide a more comprehensive maintenance plan than what’s detailed in the QM Standard,” said Donald Prather, ACCA technical services manager, “but as equipment evolves, it is important to check for updates to ensure existing maintenance plans meet the updated minimum requirements.”

ACCA’s ANSI-recognized Quality Standards are available for complimentary download to ensure every practitioner understands the minimum requirements for HVAC design, installation, service, and maintenance. To view the 2019 ACCA Quality Maintenance Standard visit
