EPA Section 608 (HVAC refrigerant): Requirements & Exam Details
Informational only — not financial or career advice. Exam fees and certification requirements change, and the figures here are accurate only as of the listed verification date. Confirm the current fee and rules directly with the certifying body before you register or budget. We report the official-body exam fee for a single attempt; it excludes prep courses, materials and retakes, and is not the total cost of certifying.
The EPA Section 608 certification is a federal credential that demonstrates competency in handling refrigerants for heating, ventilation, air conditioning, and refrigeration (HVAC-R) systems. There are no published prerequisites to sit for the exam; however, federal law requires individuals who service refrigerant-containing equipment to hold this certification. The exam covers four categories: Type I (small appliances), Type II (high-pressure systems), Type III (low-pressure systems), and Universal (all types). The credential does not expire after issuance and therefore does not require renewal.
The standard exam fee is $125 per single attempt, though fees may range from $80 to $150 depending on the testing location and proctor. The fee information provided here is accurate as of June 2026 and is subject to change. Eligibility requirements, examination fees, and all credential policies are established and maintained by EPA-approved proctors and the EPA. Before registering, candidates should verify current requirements, fees, and procedures directly on the issuing body's official website.
