Do you possibly mean your evaporator? They are much more vulnerable than the condensors. The evaporator is inside the car, buried inside the dash; the condensor sits in front of the radiator.
A good AC shop can use a sniffer to see where you're losing refrigerant (not coolant). Hopefully it's not your evaporator, since that is an expensive repair ($1800 US for mine 2 years ago).
If the evaporator is leaking, you might see AC oil dripping from under the car where condensate water normally drips out (happened to me).
