Those cans are ****. Charge to the capacity indicated on the radiator core support tag.
Typically when people top off with the can, it works great for a season and then next year same problem.So then, what options do I have?
My A/C functions, but it's not very cold.
its still not going to be a truly accurate charge
Correct. See post #7. Topping off a leaking system won't make a difference in charge amount when its going to come back out anyways - it only verifies that the system is leaking and then the moral / legal obligation is to have it repaired. This only applies if you have the Section 608 ( Types 1-3 ) or Section 609 ( mobile ) certifications. 😉I mean if you "top it off", there's no way of knowing how much refrigerant is left in the system to know how much weight to put in from the 12oz can(s). Doing it the right the system needs to be fully evacuated, legally and ethically requiring a visit to a shop to pull it one way or another, from there you can do it yourself using all that stuff to refill after finding/repairing the leak source.
