NADCA General Specifications for the Cleaning of Commercial Heating, Ventilating and Air Conditioning Systems

The Commercial General Specifications were prepared by NADCA, and describe the minimum requirements necessary to coordinate a successful commercial HVAC system-cleaning project. This guideline is for use by building owners, managers and engineers in the development of cleaning specifications.

This document must be modified to accurately account for the unique system variations within an individual building. The use of this specification in and of itself is no guarantee of a successful project. Sufficient coordination by the owner, including the selection of a qualified contractor, is as equally important as a good specification. This document was created for projects performed in the United States of America. 

For projects outside of the U.S.A., users of this specification are advised to consult applicable laws, standards and regulations of their country to ensure that the contents of this specification do not conflict with such statutes.
