If my car air conditioner is still cooling well, should I service it?
Yes, even if cooling feels fine, the system may be undercharged and waiting can lead to damage.
Quick Summary
Cooling well doesn’t mean the system is fully charged.

Yes. The air coming out of your vents may be cold enough to keep you happy, but it doesn't mean that your system is charged to specification. It may be as much as 20 percent low and still make reasonably cold air. If you wait until it stops cooling, you increase the chance of additional damage.
