EPA Regulations: Section 608 Certification in HVAC
The Environmental Protection Agency (EPA) Section 608 of the Clean Air Act regulates the handling, servicing, and disposal of refrigerants to protect the environment from ozone depletion and global warming effects. Technicians must be certified to work with refrigerants legally.

In this article:
1. What is Section 608 Certification?
✅ Required by law for anyone working with ozone-depleting and HFC refrigerants.
✅ Covers proper handling, recovery, recycling, and leak prevention.
✅ Divided into four certification types based on the type of HVAC system serviced.
2. Types of Section 608 Certification:
Certification Type | Covers |
---|---|
Type I | Small appliances (5 lbs or less refrigerant) – e.g., window ACs, refrigerators |
Type II | High-pressure systems – e.g., split ACs, heat pumps, rooftop units |
Type III | Low-pressure systems – e.g., chillers |
Universal | Covers Types I, II, and III (best for full HVAC techs) |
3. Key EPA Regulations Under Section 608
A. Refrigerant Handling & Recovery Rules
✔ Venting refrigerants is illegal – Must use an EPA-approved recovery machine.
✔ Technicians must recover refrigerant before servicing or disposing of equipment.
✔ Recovered refrigerant must be recycled, reclaimed, or properly disposed of.
📌 Tip: Always use a recovery cylinder, not a regular refrigerant tank, for reclaimed refrigerant.
B. Leak Repair Requirements
🔹 Appliances with 50+ lbs of refrigerant must be repaired if leak rate exceeds:
- Commercial refrigeration: 20% leak rate
- Industrial refrigeration: 30% leak rate
- Comfort cooling (HVAC systems): 10% leak rate
🔹 Leaks must be repaired within 30 days, or refrigerant must be recovered.
📌 Tip: Maintain detailed records of refrigerant use and leak checks for compliance.
C. Recordkeeping & Reporting
✔ HVAC businesses must document refrigerant recovery and disposal.
✔ Owners of large systems (50+ lbs) must keep leak inspection records for 3 years.
✔ Recovered refrigerant must be sent to an EPA-certified reclaimer if reused.
📌 Tip: Use refrigerant tracking logs to stay compliant.
D. Technician Certification Requirements
🔹 EPA-approved test required for handling refrigerants.
🔹 Tests are given by certified organizations (ESCO, Mainstream, HVAC Excellence, etc.).
🔹 Open-book tests are not allowed.
🔹 Certification never expires but must be re-taken if new EPA laws apply.
📌 Tip: Universal Certification is the best choice for full HVAC technicians.
4. Fines & Penalties for Violating Section 608
🚨 Illegal refrigerant venting: Up to $44,539 per violation per day.
🚨 Failure to recover refrigerant: Heavy fines & loss of certification.
🚨 Using non-certified technicians: Business penalties & EPA action.
📌 Tip: Always recover and document refrigerant properly to avoid legal trouble.
5. How to Get Section 608 Certified
✅ Study EPA 608 Certification materials (available online).
✅ Take the test through an approved EPA certification provider.
✅ Pass Core exam + at least one certification type (I, II, III).
✅ Receive official Section 608 card (valid for life).
10 FAQ on EPA Regulations:
1. What is the EPA’s role in HVAC?
The EPA regulates refrigerants used in HVAC systems to protect the environment and public health, especially under the Clean Air Act.
2. What is Section 608 of the Clean Air Act?
Section 608 sets rules for handling, recovering, recycling, and disposing of refrigerants to prevent ozone depletion.
3. Do HVAC technicians need EPA certification?
Yes, technicians who work with refrigerants must have EPA Section 608 certification.
4. What types of EPA 608 certifications are there?
There are four types:
- Type I: Small appliances
- Type II: High-pressure systems
- Type III: Low-pressure systems
- Universal: All types
5. What refrigerants are banned or restricted by the EPA?
The EPA has phased out ozone-depleting substances like R-22 (HCFC-22) and is regulating high-GWP HFCs under the AIM Act.
6. Can I still use R-22 systems?
Yes, but R-22 is no longer produced or imported. Only reclaimed or recycled R-22 can be used for servicing.
7. What are the EPA rules on refrigerant leaks?
For systems with more than 50 lbs of refrigerant, leaks must be repaired if they exceed set thresholds. Regular inspections and recordkeeping are required.
8. Is venting refrigerants illegal?
Yes, it’s illegal to intentionally vent refrigerants into the atmosphere. They must be recovered using certified equipment.
9. What is the AIM Act and how does it affect HVAC?
The AIM (American Innovation and Manufacturing) Act allows the EPA to phase down HFCs and promote safer alternatives in HVAC systems.
10. Where can I find EPA-compliant refrigerant practices?
