A homeowner asks what type of EPA Section 608 certification is required to service a small window air conditioner containing less than 5 pounds of refrigerant that will be repaired without removing the sealed system.
- AType III certification
- BUniversal certification
- CType II certification
- DType I certification
Show answer & explanationAnswer & explanation
Correct answer: D. Type I certification
Type I certification under EPA Section 608 covers technicians who service small appliances, defined as factory-sealed systems containing 5 pounds or less of refrigerant, such as window units and small refrigerators.
Why the other options are wrong
- A. Type III covers low-pressure chillers, unrelated to small appliances.
- B. Universal certification includes all types but is not the minimum required for this specific task.
- C. Type II covers high-pressure and very high-pressure systems like split-system AC units, not small sealed appliances.
EPA 608 Certification Types
EPA Section 608 requires technicians to hold one of four certification types based on the equipment they service.
- Type I: small appliances (≤5 lbs refrigerant, factory sealed)
- Type II: high-pressure/very high-pressure systems (e.g., split AC)
- Type III: low-pressure chillers
- Universal: covers all three types
Memory trick: Small appliance, small number — Type I is for the little guys.
