Summer is coming. You turn on the air conditioning. The air is lukewarm at best. You know what to do. You drive to the auto parts store, buy a small can of refrigerant, and screw it onto the low-pressure port. Within minutes, cold air flows again. Problem solved.

Except it is not. You have not solved anything. You have just masked a problem and, in all likelihood, made it significantly worse.

The "annual top-up" has become a ritual for many car owners. But here is the hard truth that professional technicians know and DIY recharge kits do not tell you: your car"s AC system is a sealed loop. It should never lose refrigerant. If it is low, you have a leak. Adding more gas without fixing that leak is not maintenance. It is a temporary bandage that is slowly destroying your compressor.

Here is why the top-up trap is one of the most expensive mistakes you can make.
