What Is EPA 608?
The EPA Section 608 certification is a federal requirement for any technician who installs, maintains, or disposes of equipment containing refrigerants. It covers safe handling, recovery procedures, and environmental regulations. Most new techs take this exam first.
The test is split into four sections — Core, Type I (Small Appliances), Type II (High Pressure), and Type III (Low Pressure). Pass all four to earn Universal certification.
NATE Core Practice Test Path
Start with the NATE Core Exam
NATE (North American Technician Excellence) is the leading voluntary certification for HVAC technicians. Employers increasingly require or prefer NATE-certified techs because it proves broad system knowledge beyond refrigerant handling.
The exam path includes a 50-question Core test plus a 50-question Specialty test such as AC, Heat Pump, or Gas Heating. For most candidates, the right first step is a free NATE Core practice test that checks safety, tools, electrical fundamentals, construction knowledge, basic science, and customer service.
After Core feels solid, move into a specialty path. Our NATE practice tests are updated for 2026 standards including A2L refrigerant transition topics.
Journeyman and License Prep Path
Who Needs a Journeyman License?
Most states require a journeyman-level license before you can work independently on HVAC systems. The exam is harder than EPA 608 — it covers the International Mechanical Code (IMC), NEC electrical rules, airflow calculations, combustion analysis, and ductwork sizing.
If you have your EPA card and a few years of field experience, journeyman prep is your logical next step toward higher pay and independent work authorization.

Try a Few Sample Questions
These are examples from our NATE and EPA question banks. The real value is choosing the right practice path above, especially the NATE Core practice path if you are preparing for NATE in 2026.
1. When using a multimeter to measure voltage across a closed switch, what should the reading be?
A closed switch has no potential difference across it. If you read voltage across a switch, the switch is open.
2. Which refrigerant is an HFO with a low Global Warming Potential (GWP)?
HFOs like R-1234yf are replacing HFCs due to environmental regulations updated for 2026.
