EPA Section 608 type selector

Match the U.S. federal certification scope to the equipment you expect to service. The result is a source-based starting point, not proof of state licensing or employer eligibility.

Official EPA pages reviewed July 19, 2026
Short answer

The equipment class determines the certification type.

Type I covers small-appliance service, Type II covers high- and very-high-pressure equipment, Type III covers low-pressure equipment, and Universal covers service across all types. MVAC service uses the separate Section 609 route.

1. Choose the equipment you expect to service or repair
2. Check EPA’s small-appliance definition

All three inputs must fit: an EPA-listed product, fully manufactured, charged, and hermetically sealed in a factory, with no more than 5 pounds of refrigerant.

Use the documented factory charge, not an estimate.

Type I matches the selected service scope

EPA defines Type I for servicing small appliances. Your selections match the listed product, factory manufacture and sealing, and five-pound-or-less charge criteria.

What to do next

Choose an EPA-approved certifying organization and verify its current testing method directly.

Section 608 Technician Certification Requirements

U.S. federal scope only. This tool does not determine state or local HVAC licensing, Canadian requirements, employer hiring standards, exam fees, or whether a specific task legally requires certification.

How the selector applies EPA’s definitions

The tool does not infer pressure class from a refrigerant name. It uses the equipment class you provide and separately checks every element of EPA’s small-appliance definition.

Type I boundary

The selected product must be on EPA’s list, factory manufactured, charged, hermetically sealed, and contain no more than 5 pounds of refrigerant.

Universal exam condition

EPA states that the Core test must be proctored for Universal certification; an open-book Core result cannot be used for Universal.

MVAC distinction

On-road motor vehicle A/C service uses Section 609. EPA permits Type II or Section 609 for qualifying MVAC-like equipment and recommends considering Section 609.

Important exceptions

EPA’s technician definition excludes disposal of small appliances, MVACs, and MVAC-like appliances from the Section 608 technician-certification requirement, but other disposal rules can still apply. Registered apprentices may work under EPA’s exemption only when closely and continually supervised by a properly certified technician.

No national fixed exam price

EPA approves certifying organizations but does not publish one nationwide candidate fee. Check delivery method, testing conditions, and current charges with the chosen approved organization. PathGauge does not estimate a fee or promise an exam result.

Rule and unit used
