So, you want to get EPA Section 608 certified? Great choice — it’s required by federal law if you work with refrigerants in HVAC systems.
Whether you’re a new technician, switching trades, or leveling up your HVAC career, this guide breaks down everything you need to know to get certified in 2025 — fast, affordably, and confidently.
EPA Section 608 certification is a federally mandated license required to service or handle equipment containing regulated refrigerants, like R-410A or R-22.
It’s named after Section 608 of the Clean Air Act, which was created to prevent ozone-depleting substances from leaking into the atmosphere.
You must be 608 certified to buy, handle, or recharge systems that use refrigerants — even if you’re just a helper.
There isn’t just one EPA license — there are four types, and which one you need depends on the kind of equipment you’ll be working on:
Type | Covers | Example Equipment |
---|---|---|
Type I | Small appliances with <5 lbs refrigerant | Window ACs, mini fridges |
Type II | High-pressure systems >5 lbs refrigerant | Central AC, heat pumps, rooftop units |
Type III | Low-pressure appliances | Commercial chillers |
Universal | All of the above | Best for career flexibility |
💡 Most HVAC techs get Universal Certification so they can work on any system.
Decide which of the four certification types fits your goals — or go all in and get the Universal.
You don’t need to go to trade school to pass the exam — but you do need to prepare.
