In most shops yes, but sometimes they dont ask for a license.
you have to have an ozone depletion license to buy it now.
R22 needs import license,R410A does not need anything special
Wal-Mart do not have r22 freon, this is a false ad.
yes you can buy bullets without a license you can also buy cartridges without a license.
No. It is illegal, will not work properly and R12 Freon is not available for the public to buy anyway.
It contained R12, which is now illegal to buy without a license, and very expensive. It can be easily converted to use a substitute, or R134, but this may be expensive.
R12 And if you still have this change over to 134a instead of buy r12
You can't. You have to be Section 608 certified and licensed to buy CFC12 (R12) in any quantity. Your best bet is to either convert it to R134a or R414b.
The freon should be R12, Which requires a license to buy these days and is very expensive. You can buy a kit to convert it to R134 freon, You should check with your local auto parts store for prices
If you are talking about the old R12 freon, you can't legally buy it. The only people who are allowed to buy it are certified air conditioning repair technicians. The government regulates R12 because it is highly toxic to the environment.
They didn't use R12 in 1995 - they'd all gone to R134a by then. Which is fortunate for you, because you can't even buy small cans of R12 without Section 609 certification.
