A/C condensator is not expensive and easy to
fix, but you need equipment to evacuate and refill the system (R134a + oil) and add the lost PAG-oil.
I would recommend exchanging the condenser by yourself and bring it to a reputable shop to do the rest. Inform them about what you did to make them calculate and top up the oil.
Use that chance to give the condensors and radiators a good clean and put some mesh to your openings in the bumber.
Edit: PAG 46
