EPA Section 608 HVAC Type I certification certifies you to work on unitary small appliances containing five pounds or less of refrigerant. 608 HVAC Type II certification certifies you to work on high-pressure and very high-pressure appliance which includes split systems and all other non-automotive systems not covered under the category of unitary small appliance or low-pressure appliance. 608 HVAC Type III certification certifies you to work on low-pressure appliances, such as chillers. 609 MVAC certification is required to work on Motor Vehicle A/C units.
No, it is not. The EPA is an U.S. agency and therefore is only valid in the U.S.
If you get a 608 certification (Type I, Type II, Type II, or Universal), you can by any refrigerant sold in an HVAC/R store in containers of 20 pounds or more. If you get 609 certification you can buy any refrigerant sold in an automotive supply house in any size container, however these stores typically only sell R-12, R-134a and replacement blends for R-12.
You must recover the refrigerant, and the technician has to be certified by EPA.
Both of these are acronyms for HFC refrigerant lubricants. PVE stands for "Polyvinyl ether" while PAG stands for "Polyalkylene Glycol." Most HFC refrigeration systems use Polyolester (POE) oil which is why the acronyms for the other two oils are not as widely well known.
Online Testing & Grading Questions
- Why does my certification status say "PASSED" and not "CERTIFIED" after I passed the R-410A, PM Tech, or IAQ Certification?
Those certifications require you to show proof of EPA 608 Certification. Your exam status is "PASSED" because our system could not find record of your 608 certification. You may either fax a legible photocopy of your certification to Mainstream at (321) 631-3552 or if you are not yet 608 certified, successfully pass our Section 608 Type I, II, or III certification exam and your
status will automatically show "CERTIFIED".
