I just started at a small shop and the owner wants me to start doing A/C recharges.

Yes, you need a federal license to purchase and handle refrigerant.

EPA Section 609 Certification is required under 40 CFR Part 82. This is a simple test covering refrigerant recovery, recycling, and safety procedures. You can take it online for free through EPA-approved providers (like MACS University or AC Service Tech).

Key points:

• Must be 18+ years old
• Test is open-book, multiple choice
• Certificate is valid for life
• Required before purchasing any refrigerant (R-134a, R-1234yf, etc.)

Shop requirements:

• Your employer should have proper recovery/recycling equipment
• Must use EPA-approved recovery cylinders
• Venting refrigerant to atmosphere is illegal (fines up to $37,500 per violation)

State/local laws: Some states have additional requirements. Check with your state's environmental agency.

Bottom line: Get your Section 609 certification first. It's quick, free, and legally required. Don't handle refrigerant without it.

Your employer should also ensure you're trained on their specific equipment before doing recharges. Safety gear (gloves, safety glasses) is essential when working with pressurized refrigerant systems.

Yes, you absolutely need EPA Section 609 certification. It is a federal requirement under the Clean Air Act (40 CFR Part 82, Subpart B) for anyone who services motor vehicle air conditioning (MVAC) systems.

The specifics:

• Buying Refrigerant: You cannot purchase any refrigerant in containers larger than 2 lbs (including R-134a, R-1234yf, or recovered R-12) without presenting a valid 609 card. Most supply houses will not sell you a 30-lb cylinder or even a 12-oz can case without it.
• Performing Service: It is illegal to service MVAC systems for pay without certification. Fines run up to $44,539 per day, per violation (adjusted for inflation, 40 CFR §82.42).
• The Test: It is an open-book, 25-question multiple-choice exam. You can take it online through approved providers (ASE, ESCO, MACS, etc.) for ~$20–$30. It covers recovery/recycling equipment standards, leak detection, and refrigerant handling.
• Recordkeeping: Your shop must certify to the EPA that they own approved recovery/recycling equipment (40 CFR §82.34). You must keep records of refrigerant purchased and recovered for 3 years.

State Note: Some states (e.g., CA, NJ, WA) have stricter rules or require additional state licenses for the business. Check your state DEQ/DMV.

Bottom line: Do not touch a machine or buy a can until you have that card in hand. The owner is liable, but you are the one risking the federal fine. Get certified today—it takes an hour.
