R134A ?

You lucky buggers...
Here in Canada you cannot buy Refer Refrigerant unless your a licensed Refer guy.
As a matter of fact , cant even buy A/C parts without a license. No way your getting anything at Walmart or any other place except at a refrigeration supply co.
When I go south I pick up a few cans R134A every time.
Environmental laws....hummmm

They do sell this "****" called Red-Tech for A/C top ups on the shelf here....but its a Propane based refer juice. Not something I recommend using for obvious reasons. I guess using a propane based gas for refer is better than actual refer gas?...not sure on that thinking.
