ACCA Standard – Restoring the Cleanliness of HVAC Systems

As a long time member of the Greater Houston, Texas, and National chapters of the Air Conditioning Contractors of America (ACCA), Power Vac America is proud to be associated with an organization that considers Indoor Air Quality and HVAC System cleanliness important enough to write a standard for HVAC contractors.  The ACCA standard shares many of the standards published by the National Air Duct Cleaners Association (NADCA).

The Restoring the Cleanliness of HVAC Systems standard was developed by ACCA to provide useful, explicit and workable guidelines that will provide contractors the ability to differentiate themselves based on additional services provided and establish performance criteria for all reputable contractors.

The standard defines minimum procedures and practices to:

  • Determine when airside surfaces should be cleaned and when they should be replaced.
  • How to clean the airside surfaces within HVAC systems.
  • How to control the spread of contaminants which may be release as a result of the HVAC cleaning process.
  • Verify the cleanliness of the HVAC system.

The standard also helps establish a framework for providing better Indoor Air Quality.  While following the standard might not resolve all Indoor Air Quality issues, it can definitely be a major remedy and helps a contractor demonstrate that industry-accepted options to rectify a system’s poor IAQ and poor performance are being followed.

HVAC systems are complex to dismantle and reassemble.  This limits the number of qualified individuals who can appropriately access the internal components.  Simply cleaning the ducts without properly addressing the other system components may have little or no impact on improving the overall HVAC efficiency or IAQ problems.  The standard addresses this important fact.

This standard, developed and supported by ACCA, should encourage you to take a more aggressive role in actively seeking to keep your customers health, comfort, and Indoor Air Quality problems in mind.

Again, we are proud to be a member of ACCA and working with all of the ACCA contractors and both the ACCA and NADCA standards.
