## HVAC EPA 608 Exam Prep Description
HVAC EPA 608 EXAM PREP: PASS YOUR CERTIFICATION ON THE FIRST TRY

Every HVAC technician working with refrigerants must hold an EPA 608 certification under Section 608 of the Clean Air Act. The exam has four sections — Core, Type I, Type II, and Type III. You need to pass all four to earn your Universal certification card. A passing score is 18 out of 25 correct on each section, and each section is graded independently.

Most technicians fail because they don't know which section is weak until they're sitting in the testing center. This app tracks your score separately for each section so you know exactly where to focus before exam day.

REFRIGERANT CALCULATOR

The data the Core section tests every single time. Covers R-410A, R-22, R-32, R-134a, R-404A, and R-407C. For each refrigerant: ODP (ozone depletion potential), GWP (global warming potential), operating pressures, refrigerant type (HCFC, HFC, HFO), and phase-out status under the AIM Act and Montreal Protocol.

These values appear on the Core exam in almost every sitting. Most technicians memorize them wrong. This calculator gives you the correct values instantly and explains why they matter for the exam and on the job.

PRESSURE-TEMPERATURE REFERENCE

Instant P/T lookups for all common refrigerants. Enter a pressure, get the saturation temperature. Enter a temperature, get the corresponding pressure. Includes superheat and subcooling references for R-410A and R-22 systems. The same reference you will use on every service call long after you pass the exam.

1,000+ PRACTICE QUESTIONS

Core: Ozone layer chemistry, Clean Air Act Section 608 requirements, refrigerant safety and handling, recovery requirements before opening a system, leak detection, record keeping, sales restrictions on refrigerants above 2 lbs, civil and criminal penalties.

Type I (small appliances, 5 lbs or less): Passive recovery techniques, system-dependent recovery, disposable cylinder requirements, recovery efficiency standards, evacuation levels for small appliances.

Type II (high-pressure systems): Evacuation levels by equipment age and size, recovery equipment certification, leak repair requirements for systems with 50+ lbs of refrigerant, low-loss fittings, pressure testing procedures.

Type III (low-pressure systems, chillers): Deep vacuum requirements, purge unit operation and emissions, pressurization for leak testing with nitrogen, chiller-specific leak rates and repair timelines.

Universal: All four sections combined, weighted to match actual exam distribution.

Every question tells you which section it covers, explains why the correct answer is right and why each wrong answer is wrong, and references the specific EPA regulation behind the rule.

MOCK EXAM MODE

Simulates real test conditions: 25 questions per section, timed, no explanations until the section is complete. Get your pass/fail for each section separately — exactly how the real exam scores it.
