About ACCA

ACCA is a non-profit association whose membership includes more than 60,000 professionals and 4,000 businesses in the indoor environment and energy services community. We work together to promote professional contracting, energy efficiency, and healthy, comfortable indoor environments.

Our roots stretch back to the early part of the 20th century, and the organization was incorporated in its present form over 40 years ago. As the leading indoor environment contracting association, in addition to providing direct services and benefits to our members, we actively serve the entire industry. 

How do we do it?

ACCA is the only nationwide organization of, by, and for the small businesses that design, install and maintain indoor environment and building performance systems. 

Not a member? We’d love to serve you, too.
