EPA 608 Type 1 (Small Appliances) Practice Test

Type I. Persons who maintain, service, repair, or dispose of small appliances must be certified as Type I technicians. A small appliance is defined as a pre-assembled unit that is hermetically sealed and factory-charged with 5 lbs. or less of refrigerant. Examples include water coolers, window units, refrigerators, freezers, dehumidifiers, ice machines, and package terminal air conditioning. Split systems are not included in Type I.

Our test comprises 35 questions on EPA 608 Type 1 (Small Appliances). Registration is not required, and you can check your score at the end of the test.
