F-gas certification: how to check your AC installer in the register
Refrigerant work on an AC — connecting, charging, leak-checking the lines — must be done by a person certified for work with refrigerants (F-gases), and Latvia's State Environmental Service (VVD) publishes a searchable public register of certified specialists. Checking takes a minute: search the installer's name or certificate number before signing. A company that hesitates to name its certified technician is telling you something.
Key takeaways
- Split-system refrigerants are fluorinated greenhouse gases (F-gases) regulated EU-wide — handling them legally requires a personal competence certificate.
- Latvia's official check: the State Environmental Service (VVD) register of certified persons for work with refrigerants — public, searchable by name or certificate number, exportable.
- Certification is issued by accredited bodies (LATAK-accredited certification centres; LSIA and LSGŪTIS are the sector's institutions) in categories by scope of work.
- The certificate matters practically, not just legally: vacuum, charging and leak-tightness are exactly the skills the certificate examines — and exactly what cheap installs skip.
- Ask one question before signing: 'Who exactly will do the refrigerant work, and what's their certificate number?' Then spend one minute in the register.
What the rule is
The refrigerant inside every split system is a fluorinated greenhouse gas (typically R32 today, R410A in older units) with a global-warming potential hundreds to thousands of times that of CO₂. EU F-gas regulation therefore requires that the people who install, service, leak-check or recover refrigerant hold a personal competence certificate, issued in categories by scope of work.
In Latvia, certification is run by accredited certification bodies (accredited by LATAK to ISO/IEC 17024) — the refrigeration sector’s institutions LSIA and the LSGŪTIS certification centre among them — and the resulting certified persons appear in a public register maintained by the State Environmental Service (VVD).
The one-minute check
- Ask the company: “Who exactly will do the refrigerant work, and what’s their certificate number?”
- Open the VVD register of certified persons for work with refrigerants.
- Search by surname or certificate number. The register is public and searchable; results can even be exported.
| Response you get | What it means |
|---|---|
| Name + number, instantly | Normal professional answer |
| ”Our guys are all certified” (no names) | Ask again; verify before signing |
| ”It’s not needed for small units” | It is. Walk away |
Why you should care beyond legality
The certificate examines precisely the steps a buyer cannot see and a corner-cutter skips: pulling a proper vacuum before charging, leak-checking, charging correctly for the actual line length, and recovering refrigerant instead of venting it. These are the same items we flag in what a proper quote contains — the difference between an installation that performs for a decade and one that fades every summer until the compressor gives up.
So the register check is not bureaucracy-for-its-own-sake: it is the cheapest predictor of installation quality available to a consumer, and it filters the suspiciously cheap offers better than any review site.
Where this fits in your sequence
Verify certification when you shortlist installers — before quotes, alongside checking that your placement’s facade rules and manager procedure are settled. One minute per company, once.
Frequently asked questions
Why does a home AC install legally need a certificate at all?
The refrigerant in a split system is a fluorinated greenhouse gas with a global-warming potential hundreds to thousands of times CO₂'s — EU F-gas rules therefore require that anyone installing, servicing or recovering refrigerant holds a personal competence certificate. It applies to the person doing the work, which is why 'the company is experienced' is not an answer.
How exactly do I check an installer?
Open the VVD register of certified persons for work with refrigerants (linked in Sources), enter the technician's surname or certificate number, and check the entry. If you can't find them, ask the company for the exact name and number of the person who will handle the refrigerant — a professional answers instantly.
The price is good but there's no certificate. What actually goes wrong?
The certificate examines exactly the invisible steps: pulling proper vacuum before charging, leak-checking, correct charging for the line length, refrigerant recovery instead of venting. Skipping them produces a unit that cools worse each season and a compressor that dies young — plus an illegal vent of a potent greenhouse gas. You find out in year three, long after the discount.
Does the certificate cover the whole installation?
No — it covers the refrigerant circuit. Electrical work has its own competence requirements, and facade placement has its own rules. A serious installer covers all three; the F-gas register is simply the one you can verify yourself in a minute.
Is a certificate from another EU country valid?
F-gas certification is EU-harmonised, and certificates from other member states are recognised in principle. For a Latvian consumer the practical path is still the VVD register; for a foreign certificate, ask for the document itself and the issuing body.
