Regular Membership

NADCA Regular Members are companies that are actively engaged in the business of performing residential, commercial and/or industrial air duct cleaning services while retaining at least one certified Air System Cleaning Specialist (ASCS) on staff at each location. If your firm does not provide HVAC system cleaning services, it cannot be accepted for Regular Membership. Only Regular Members have voting rights within the organization. Membership dues are payable on an annual basis and are non-refundable. 

Membership Requirements

In order to become an active Regular Member, companies must meet the following requirements:

  • Full payment of one-time application fee
  • Full payment of annual membership dues
  • ASCS certified technician on staff
  • Submission of Certificate of liability insurance (naming NADCA as a certificate holder) 

Companies must fulfill all membership requirements within a period of 6 months from the date of application submission. Your company’s membership status will be pending until all membership requirements are met. During pending membership status, your company is not a NADCA member, cannot claim NADCA membership and is not eligible for NADCA benefits, including use of the NADCA logo. Your company is not a NADCA member until it has been issued an official NADCA Membership Certificate.

Is a license required to be a Regular Member?

NADCA membership does not require a license for HVAC cleaning, however, we strongly recommend that you contact your state licensing agency to learn what licenses if any are required, so you are compliant with your state’s requirements. Following are some states which do require an HVAC contractor’s license, mechanical contractor’s license, sheet metal license, or other specialty license in order for a firm to access and clean HVAC systems.

  • Arizona (602) 542-1525
  • Arkansas (501) 661-2642
  • California (916) 255-3900
  • Florida (850) 487-1395
  • Georgia (478) 207-1416
  • Michigan (517) 241-9325
  • Texas (512) 463-6599.

Examples of state mandated licenses that would apply to NADCA members would relate to cutting access holes, working with asbestos, applying pesticides, or providing residential services. Companies should contact their state's Department of Labor for more information.

What is the cost of Regular Membership?

Regular Membership dues are charged on an annual basis at the cost of $860.00 per year and are non-refundable. Dues are payable by June 30 of every year. When a company first joins NADCA, dues for the first full year (July 1 through the following June 30) are prorated based upon when membership began. Companies that have not fulfilled their membership requirements in 6 months from the time of application will forfeit their application fees and dues.

Where can I take the ASCS certification exam?

The ASCS exam must be taken in person at one of our testing centers or at a NADCA event. ASCS training courses and exams are offered at NADCA's Fall Technical Conference and Annual Meeting & Exposition. If you are planning to submit a New Member Promotional Package membership application, a member of the NADCA staff will schedule the exam for you.
