I hope you didn't and don't mind the hijack, if so I apologize, Chocaholic.

Please explain to me how any freon is added even if the outside unit came fully charged? How does anyone know how much freon is needed when it varies from house to house? Surely, it depends on how much copper line is needed, not to mention the evaporator. The capacity varies, and pressures vary depending on ambient temps.

Cracking the valves to inject is nice, but when the valve leaks, there's the stand bye, an old dried out bicycle valve, to catch, what escapes past the first valve. Slow leaks are inevitable.

I didn't support the ban on R22, or any other refrigerant for that matter, but there's a hold on 134, which if you ask, is left unexplained. It doesn't take a rocket scientist to figure it out. We both know. Home a/c's are sealed on one side of the argument, but are not a sealed system on the other side.

If it doesn't leak, it's not designed to leak, it will never leak. Then why tap into another refrigerant market? HCFC, HFC, going to wipe out everyone, bla, bla, bla.

I'll give you warn out parts, it happens. But please explain to the rest of us why an a/c system that still holds pressure, would leak out freon over the winter.

Maybe I'm wrong, but I'm fairly certain there are valve cores.
