Question 1Section 608 rules
A wholesaler is asked for a 30 lb cylinder of R-22. Which buyer may the wholesaler sell it to?
What refrigerant certification costs
EPA does not set or publish a fee. Each EPA-approved certification program sets its own price for the test and the card, so compare a few before you book.
| Fee set by | Each approved program |
|---|---|
| Renewal cost | None: it does not expire |
| Card | From the program, within 30 days |
| Lost card | Replaced by the program |
What you pay for
- The test itself: Core plus the types you need, or Universal.
- Proctoring, in person or remote, for closed-book tests.
- Your wallet card, issued by the program.
- A retake, if a section falls short of 70 percent.
Why one pass lasts
Section 608 certification does not expire, so the test is a one-time cost. The rule asks you to keep a copy of your certificate at your place of business until three years after you stop working as a technician.
Finding a program
EPA lists every approved program with its headquarters and approval date. Some test remotely, and some test only their own employees. EPA does not review or approve preparation courses, including this one.

Question 2Safety
A recovery cylinder would hold 30 lb of liquid R-22 if filled completely. It already holds 15 lb. How much more can be added under the 80 percent limit?
Question 3Small appliance recovery rules
A water cooler's nameplate lists a 10-ounce charge. Its compressor runs, and the recovery equipment was made in 2019. What is the least the technician may recover?

Questions people ask
How much is the EPA 608 test?
EPA does not set the price. Each approved certification program sets its own, so check two or three on EPA's list.
Do I pay to renew?
No. The certification does not expire.
Can I get certified for free?
The test fee is set by the program you choose. Practice here is free to start: a diagnostic, a full Core practice test and a short test for each type.
