| Inspect the A/C components for oily spots, possibly dirt clinging. Look over the condensor (in front of the radiator) you may have picked up a small stone. The front seal on the compressor is also a weak link. If everything looks good under the hood, the leak may be the evaporator core. It's inside the vehicle and cannot be seen without disassembly.
An A/C shop should be able to find any leaks, and many charge little or no fee, hoping you'll buy their recommended repair(s) Be sure to ask about diag fees upfront and ask, too, about warranties. If they don't want to be open, don't give them your keys.
Good luck!
