Delaware to Texas: journeyman HVAC technician license reciprocity

Texas has no journeyman HVAC license in the usual sense; the person-held credential for an employee who does air conditioning and refrigeration work is the Registered ACR Technician registration issued by the Texas Department of Licensing and Regulation (TDLR). Anyone who assists a licensed ACR contractor with non-exempt maintenance or repair work must register: the applicant must be at least 16, file a one-page application with a $20 fee and answer a criminal history questionnaire, and there is no exam, no experience requirement and no continuing education. The registration is valid one year and is renewed for $20. TDLR also offers a voluntary Certified ACR Technician credential for technicians with 24 months of supervised experience or a TDLR-approved 2,000-hour training program who pass a PSI exam ($50 application, $60 exam, renewed for $35); it is not required to work. Because the registration is not an examined license, an out-of-state journeyman or technician license has nothing to transfer to: every technician must register with TDLR regardless of licenses held elsewhere, and all work must be performed under a Texas-licensed ACR contractor. Technicians who handle refrigerants also need federal EPA Section 608 certification.

Delaware does not issue a journeyman or journeyperson HVACR license. The Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners issues only Master Plumber, Master HVACR and Master HVACR Restricted licenses, and 24 Del. C. § 1820(c)(1) lets 'an apprentice, journeyman, mechanic or other person' provide HVACR services without a license while working under the supervision of a master HVACR licensee who is their employer or a full-time employee of the same business. An out-of-state journeyman license therefore has nothing to transfer to in Delaware and is neither required nor recognized for employment; technicians who service refrigerant-containing equipment still need federal EPA Section 608 certification. Delaware's own 'journeyman certificate' is a certificate of completion from a federally-registered HVACR apprenticeship program, which is an experience credential used toward the master license rather than a license: with it, 2 years of post-apprenticeship work under a master (in Delaware or under a similar-level licensee in another state) qualifies an applicant for the Master HVACR exam, and without it 7 years of supervised experience plus the Apprenticeship By-Pass exam are required. Out-of-state journeyman experience gained under a licensed master counts toward those requirements.
