Air Conditioning and Refrigeration Contractors Guidelines for Suppliers

Air Conditioning and Refrigeration Licenses:

Require a copy of the 8-1/2 x 11 license for licenses issued before March 7, 2001, not the ID card, because the card did not show the company to which the license is assigned. Starting March 7, 2001, the wallet card is the actual license and has all pertinent information on it.
Record the license number, company name (only one company on a license, although assumed names may be shown), and expiration date of the license.
Bill to the company, not an individual, unless the individual is the licensee and he is the company.
Cash sales of equipment and refrigerants made to individuals may be used for illegal jobs, which could possibly involve you in liability for jobs that go wrong.
Keep track of expiration dates. When the license is renewed, check the company name again to be sure the licensee is still with the same company.
Check with the Department if something seems irregular.

Certificates of Registration

Record Certificate number and the name of the employer. These have no expiration date. One person may be employed as a maintenance employee of more than one employer at a time. If so, a separate Certificate of Registration is required for each company.
Require purchase orders. Cash sales are often for illegal side jobs, and may involve liability for the supplier and/or the employer.

Exemptions

Homeowners are exempt from purchasing requirements of the state, but not from the EPA.
Persons working on automobile air conditioning.
Persons working for regulated utilities or heavy industry, but only when purchasing for their employer.
Persons who work on small appliances, as defined by the Clean Air Act.
