Which EPA 608 exam does Georgia use?
Georgia HVAC technicians take the federal EPA Section 608 Technician Certification exam. The exam is the same in every state — it is administered by EPA-approved certifying organizations including ESCO Institute, Mainstream Engineering, HVAC Excellence, and RSES. Test sites and proctoring options (in person or online) vary by certifying organization, so confirm availability in Georgia with the organization you choose.
The exam was created under Section 608 of the Clean Air Act (40 CFR Part 82, Subpart F) to ensure that anyone who services refrigerant-containing equipment understands the environmental and safety rules for handling refrigerants. Federal law requires certification before a technician can service, repair, or dispose of refrigerant equipment in any state.
Georgia does not have its own refrigerant-handling exam. Some states also license HVAC work separately from the federal credential. Check with the Georgia State Construction Industry Licensing Board — HVAC for current Georgia requirements, and see the state license section below.
EPA 608 exam format and Type I/II/III breakdown
The EPA Section 608 exam is divided into a Core section that everyone takes and four Type sections you select based on the equipment you service. Each section is a separate 25-question multiple-choice test; Universal is all four sections (100 questions). Time limits are set by the certifying organization.
The four certification types
- Type I — Small Appliances — Personnel servicing or disposing of small appliances that contain less than 5 pounds of refrigerant (e.g., window AC units, refrigerators, freezers, vending machines).
- Type II — High-Pressure Appliances — Personnel servicing or disposing of high-pressure appliances (e.g., residential split AC, heat pumps, package units, commercial refrigeration).
- Type III — Low-Pressure Appliances — Personnel servicing or disposing of low-pressure appliances (e.g., centrifugal chillers).
- Universal — Personnel servicing or disposing of all appliance types — combines Type I, II, and III coverage in one credential. The most common credential held by HVAC technicians.
Most HVAC service technicians hold the Universal credential, which covers Type I, II, and III in one certification. It is the right choice unless you work exclusively on a single appliance category (for example, only residential refrigerators — then Type III alone is sufficient).
Core section — every technician takes it
The Core section covers Clean Air Act Section 608 regulations, refrigerant recovery and recycling procedures, leak detection and repair requirements, recordkeeping, and safety. You must pass the Core section plus at least one Type section to earn a credential. The Core is 25 questions.
Proctoring and reference materials
Format and what you may bring vary by certifying organization, so confirm both with yours before exam day. EPA states that a Core test taken as an open-book exam cannot be used to get your Universal certification, and that the Core must be taken as a proctored exam to attain Universal. Type II, Type III, and Universal exams are generally proctored and closed-book.
The passing score for each section is 18 of 25 (72%). If you fail one section, you can retake that section without retaking the ones you passed.
EPA 608 training and Georgia state license
The EPA does not require a specific number of training hours for Section 608 certification. Preparation time depends on your background; many candidates study the refrigerant handling, recovery equipment, and leak-repair material on their own or complete a formal HVAC program or apprenticeship.
Beyond the federal EPA 608 credential, some states license HVAC contractors or technicians separately, and the rules differ by state. Check the Georgia State Construction Industry Licensing Board — HVAC at https://sos.ga.gov/index.php/licensing/plb/225 for the current Georgia requirements before you start work.
If you have prior HVAC experience — for example, military refrigeration training, factory service training, or years of documented HVAC work — the certifying organization may waive the training prerequisite. Check the ESCO or Mainstream candidate handbook for the current equivalency rules.
How to apply for the EPA 608 exam in Georgia
Follow these steps to register for the EPA Section 608 exam in Georgia.
Step 1 — Choose a certifying organization
EPA-approved certifying organizations deliver the same exam with different study materials and brand recognition. ESCO Institute is the most widely used; Mainstream Engineering is popular for its research-driven curriculum. Pick the one that fits your study style and budget.
Step 2 — Complete the recommended training
Study the candidate handbook and reference materials. Spend your study time reviewing the Core + Type sections, the recovery/recycling/reclaim procedures, and the leak-detection-and-repair requirements.
Step 3 — Schedule your exam
Schedule with your certifying organization (in person or through a proctored option they offer). The Universal bundle covers all four sections in one sitting; single-Type exams cover one section. You will receive an admission letter by email.
Step 4 — Pay the exam fee
Exam fees are set by the certifying organization (and any proctor) and vary with the number of types you sit for. Some employers reimburse this fee — ask your employer before paying out of pocket.
Step 5 — Pass the exam and receive your card
After passing, the certifying organization mails a Section 608 technician card to you. Carry this card whenever you service refrigerant equipment — federal inspectors and Georgia state inspectors may ask to see it.
Exam day checklist for Georgia EPA 608 candidates
The morning of your exam, give yourself plenty of time. Plan to arrive 30 minutes before your scheduled time to allow for check-in, ID verification, and locker assignment. Late arrivals may forfeit their fee.
What to bring
- Whatever ID your certifying organization requires (check your admission instructions)
- Your admission letter or confirmation (printed or on your phone), if the certifier issues one
- Payment receipt or confirmation number
- Only the reference materials your certifying organization explicitly allows; confirm with them first
- Comfortable, layered clothing
What to leave at home
- Cell phones, smart watches, and other devices unless your certifier says otherwise
- Notes or marked-up reference materials unless your certifier explicitly allows them
- Food and drinks (water in a clear bottle is usually allowed)
- Scrubs with logos or identifying marks from your training program
During the exam
Time limits are set by your certifying organization. Read each question carefully, and know the regulatory material (for example, the requirements in 40 CFR Part 82 Subpart F) well enough that you do not depend on looking things up.
EPA 608 exam cost and fees in Georgia
The EPA does not set the Section 608 exam fee. Each EPA-approved certifying organization (and, where used, the proctor) sets its own prices, and they vary by organization and by which types you sit for, so check current fees with the organization you choose before you register.
On top of the exam fee, plan for any HVAC training you choose to take; tuition varies widely by provider. Some employers and apprenticeship programs cover the exam fee.
Retake fees: if you fail one or more sections, retake fees and rules are set by the certifying organization. Any Georgia state licensing fees are separate — see the Georgia State Construction Industry Licensing Board — HVAC website for current costs.
How to prepare for the Georgia EPA 608 exam
How long you need depends on your background, but plan on focused study before the exam. Because the Universal Core must be taken proctored (and an open-book Core does not count toward Universal), the goal is to know the material well enough to answer without references. Here is the study plan we recommend for Georgia.
Week 1 — Review the CFR structure
Open a clean copy of 40 CFR Part 82 Subpart F and learn its layout. The exam questions cite specific paragraphs (§82.150, §82.155, etc.). If you can flip to the right paragraph in under 10 seconds, you'll save minutes per question on exam day.
Week 2-3 — Practice questions daily
Use our EPA 608 practice question bank to drill 25-50 multiple-choice questions per day. Read every explanation — even for questions you get right — so you understand the reasoning the EPA expects. Aim for a consistent score above 18 of 25 (72%) on practice tests before scheduling your exam.
Week 4 — Recovery/recycling/reclaim walkthrough
Practice the recovery, recycling, and reclaim procedures for each appliance type. Know the difference between recovery and recycling, the evacuation requirements before opening a system, and the cylinder-weight limits for transporting recovered refrigerant.
Week 5 — Full-length simulations
Take at least two full-length timed simulations in our EPA 608 exam simulator. Build your test-day stamina by sitting through the full Universal exam (Core + 3 types) without breaks.
