EPA 608 Type I Practice Test
Updated October 26, 2026
Type I certifies you to service small appliances: factory-made, charged and hermetically sealed equipment with 5 pounds of refrigerant or less, such as household refrigerators, freezers, window air conditioners, PTACs, dehumidifiers and water coolers. To be certified for Type I you pass Core and the Type I section, each 25 questions. Try the free questions below.
What Type I covers
- Which equipment counts as a small appliance.
- How much refrigerant must be recovered, and how.
- Active (self-contained) and passive (system-dependent) recovery.
- Access fittings, including piercing valves.
- Safety, and the rules for disposing of small appliances.

-
Which of these is a small appliance under EPA's Section 608 rules?Answer: DA small appliance is manufactured, charged and hermetically sealed in a factory with 5 pounds of refrigerant or less. A household refrigerator qualifies. A split system is field-assembled and covered by Type II, and a centrifugal chiller using R-123 is low-pressure equipment covered by Type III.
-
Using recovery equipment made after November 15, 1993, how much refrigerant must be recovered from a small appliance whose compressor is operating?Answer: CWith recovery equipment made on or after November 15, 1993, recover 90% of the refrigerant if the compressor runs, or 80% if it doesn't. Alternatively, the appliance can be evacuated to 4 inches of mercury vacuum.
-
When using passive (system-dependent) recovery on a small appliance with an operating compressor, what should the technician do?Answer: AIn system-dependent recovery, the appliance's own compressor pumps refrigerant into a non-pressurized recovery container. If the compressor doesn't run, access both the high and low sides, and warming the compressor or tapping it can help release refrigerant trapped in the oil.
-
Why should solderless piercing-type access valves not be left on a small appliance permanently?Answer: BPiercing valves are handy for accessing sealed systems, but they tend to leak over time. Install them following the manufacturer's directions, leak-test them, and replace them with a permanent fitting or remove them as appropriate once the work is done.
-
A small appliance is going to a scrap yard. Who is responsible for making sure the refrigerant has been recovered?Answer: CThe last person in the disposal chain must make sure the refrigerant has been recovered, either by recovering it or by getting a signed statement that it was recovered earlier, which must include the name and address of the person who recovered it and the date.
-
An old refrigerator uses an absorption system with ammonia, hydrogen and water. Technician A says standard recovery equipment should be used to recover the refrigerant. Technician B says EPA's recovery rules for ozone-depleting refrigerants don't apply to it. Who is right?Answer: BAbsorption systems that use ammonia, hydrogen and water don't contain the ozone-depleting refrigerants the recovery requirements cover, so B is right. Standard recovery equipment isn't designed for ammonia and shouldn't be used on these systems, so A is wrong.
-
Before recovering refrigerant from a small appliance, why should the technician check the refrigerant type?Answer: DMixed refrigerants usually can't be separated and reclaimed, so they may have to be destroyed. Use a dedicated recovery container for each refrigerant, and check the nameplate, and if needed the pressure and temperature, to confirm what's in the system.
-
Refrigerant recovery equipment made after November 15, 1993 must be:Answer: ARecovery and recycling equipment made after November 15, 1993 must be certified by an EPA-approved equipment testing organization (such as AHRI or UL) to meet EPA's performance requirements. Gray with a yellow top describes recovery cylinders, not recovery machines.
Type I by mail or online
Some certifying organizations offer Type I alone as an open-book test by mail or online. That version requires 84% (21 of 25), and it can’t count toward Universal certification. Practise Core questions too: EPA 608 Core practice test.
