Can You charge R134a with 12oz cans?
If the method of charging R134a is with 12oz cans, then you have to compensate for the amount of refrigerant to an even greater extent. You will still need to allow 2oz for the service hoses and since you can never completely empty a can of refrigerant you will need to allow for an additional 1oz per can.
Can a can of pressurized AC oil work in a car?
That’s another area where DIYers get into trouble. There’s no single car AC oil that works well in all cars. If you just bought a can of pressurized car AC oil, you may be screwing up the system.

What does the low side of the AC R134a do?
Remember that the Low side, also known as the suction side, normally operates as a “Low Pressure Vapor” state that is drawn directly into the compressor. You don’t want to “slug” the compressor by inverting the can and adding freon in the liquid state.
Are there any new 134a air conditioners coming out?
No announcement yet. Has anyone but me fallen victim to the latest A/C change?
