Delaware to District of Columbia: journeyman HVAC technician license reciprocity
Delaware does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is District of Columbia's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state journeyman HVAC technician (any state)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
The Board of Industrial Trades publishes no reciprocity for refrigeration and air conditioning mechanics, so a journeyman-level HVAC licensee from any state applies through the DLCP online portal as a new applicant. The application needs a passport-style photo, government ID, the $65 application fee, tax records and an employment verification letter signed by a master mechanic showing at least 3 years of experience, and a CFC Universal certification; the applicant then schedules the open-book journeyman exam with PSI (2012 International Mechanical Code and Modern Refrigeration and Air Conditioning) and pays the $110 license fee for a term ending September 30 of the next even-numbered year. Two statutory routes can waive the exam: D.C. Code § 47-2853.202(d) requires the Board to accept a certificate from a national certifying organization (a registered trade organization, non-union sponsor or labor union) that the applicant completed its apprenticeship, passed its exam and is designated a journeyman, and § 47-2853.12(b) directs boards to waive the exam for a licensee in good standing of a state whose standards were at least as high as the District's and which admits DC licensees in a like manner, with § 47-2853.08 leaving the substantial-equivalence finding to the Board case by case. No District-law exam applies; § 47-2853.12(c)(4) exempts journeyman refrigeration and air conditioning mechanics from one.
PSI's District of Columbia candidate bulletin lists the journeyman refrigeration exam fee as $52 per attempt. Whether experience letters signed by an out-of-state master are accepted, and which states or national certifying organizations the Board has listed under § 47-2853.12(d), are not stated in the Board's published materials. The 3-year experience figure comes from DLCP's application instructions; the statute itself sets no journeyman experience term.

How District of Columbia licenses journeyman HVAC technicians
District of Columbia journeyman HVAC technician · “Journeyman Refrigeration and Air Conditioning Mechanic”
Statewide license
Issued by DC Board of Industrial Trades (Department of Licensing and Consumer Protection)
The District of Columbia licenses HVAC technicians as Refrigeration and Air Conditioning Mechanics through the Board of Industrial Trades in the Department of Licensing and Consumer Protection (DLCP), the same board that licenses electricians and plumbers. Three person-held credentials exist: apprentice (registered without exam), Journeyman Refrigeration and Air Conditioning Mechanic, and Master Refrigeration and Air Conditioning Mechanic (regular, or limited to systems of 25 compressor horsepower and below). 17 DCMR § 303.7 requires a journeyman license for anyone doing the mechanical work of installing, maintaining, repairing or replacing refrigeration and air conditioning equipment. DLCP's application instructions require 3 years of experience verified by a master, tax records, a CFC (EPA 608) Universal certification, and a PSI-administered open-book journeyman exam; a graduate of a registered apprenticeship program (classroom work plus 8,000 hours over 4 years under a master) may waive the journeyman exam, which mirrors the national-certification substitute in D.C. Code § 47-2853.202(d). Fees are a $65 application fee and a $110 mechanic license fee; all refrigeration licenses expire September 30 of even-numbered years. The Board publishes reciprocity for electricians and plumbers from Maryland and Virginia but none for refrigeration and air conditioning mechanics.

Why Delaware has nothing to transfer
Delaware journeyman HVAC technician
No individual license at this level
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.
