1. What is the phone number for the EPA Ozone Protection Hotline?
The EPA Ozone Protection Hotline toll-free number is 1-800-296-1996
2. What type of A/C systems am I certified to work on with each type of certification?
EPA Section 608 HVAC Type I certification certifies you to work on unitary small appliances containing five pounds or less of refrigerant. Section 608 HVAC Type II certification certifies you to work on high-pressure and very-high-pressure appliances which include split systems and all other non-automotive systems not covered under the category of unitary small appliance or low-pressure appliance. Section 608 HVAC Type III certification certifies you to work on low-pressure appliances, such as chillers. Section 609 MVAC certification is required to work on motor vehicle A/C units.
3. Is EPA Certification valid in countries other than the United States?
No. The EPA is an U.S. agency and therefore is only valid in the U.S.
4. What type of Certification do I need to purchase refrigerants?
If you get a 608 certification (Type I, Type II, Type II, or Universal), you can buy 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.
5. Can HFC refrigerant be released into the air, or does it have to captured? Also, does the technician handling the refrigerant have to be licensed?
You must recover the refrigerant, and the technician has to be certified by EPA.
6. I saw the two acronyms PVE and PAG in a January 2008 RSES article written by Mainstream, but I'm not sure what they are in reference to.
Both these acronyms are for HFC refrigerant lubricants. PVE stands for "polyvinyl ether" and 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 well known.
Online Testing & Grading Questions
1. 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 a record of your 608 certification. You can 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.
2. How secure is my credit card over the internet?
When you connect to the EPA test site, your browser indicates it's connected with a secure server (note the locked key or lock on your browser). Our webserver uses the Secure Sockets Layer (SSL) protocol, a security protocol that provides privacy over the internet. This protocol allows client/server applications to communicate in a way that cannot be eavesdropped. Our server site is registered with a certificate authority (CA), in this case VeriSign, so you know who you are connecting to. After we get your credit card information, it is validated through VeriSign. VeriSign encrypts your card information using highly secure 128-bit public key encryption technology. Mainstream Engineering Corporation is using these widely available technologies to guarantee the privacy of your information. If you still have questions or concerns, please e-mail us at firstname.lastname@example.org.
3. I don't have a credit card. Is there any way to take the exam on-line and pay by check?

4. I got partially through the exam process, and I lost my connection. What can I do? Will I be charged again? Are all of my answers lost?
