ALEXANDRIA, VA. — The standards task team at the ACCA Educational Institute (ACCA-EI) has announced American National Standards Institute (ANSI) approval for the reaffirmation of ACCA 4 QM – 2019 (R2024), Maintenance of Residential HVAC Systems.

ANSI approved the reaffirmation last month after a 45-day public review period during which no comments were received. This was done to comply with ANSI’s essential requirements, which require ANSI standards to either be withdrawn, revised, or reaffirmed every five years.

The ACCA 4 QM standard provides a nationally recognized, manufacturer-endorsed set of minimum tasks that should be performed during maintenance inspections of residential HVACR equipment. From this list, consumers can compare the value of additional recommended corrective actions that may be needed to remedy identified faults.

For contractors, the standard provides a common platform for creating a maintenance program while allowing for bundling of different recommended corrective actions.
