Which certifications can an HVAC technician list on a resume?

List every recognised certification you hold, with the issuing body and expiry date, in a section near the top. Commonly seen examples include EPA Section 608 certification in the US, F-gas certificates in the UK and EU, NATE certifications, manufacturer training (for example on VRF or chiller brands), and your national trade certificate in refrigeration and air conditioning.

Example format (fictional):

• "Refrigeration and Air Conditioning Trade Certificate – National Technical Board, 2019."
• "F-gas Category 1 certificate – 2022" (UK/EU example).
• "VRF installation and service training – [manufacturer], 2023."

Requirements for handling refrigerants and doing HVAC work differ between countries. If your local authority requires a licence or certificate, list it exactly as issued, with its number and expiry, and check the job advert for what the employer asks for.
