AC failure is common on civics because the condenser sits unprotected in the front grill in front of the radiator..

It could be a bad compressor but you might just have a hole in the condenser from road debris. If that's the case, you'll need a new condenser (aftermarket is fine) refill the system with the correct amount of PAG oil and a refrigerant recharge.

Any average shop should be more than capable of doing the job. Hardest part is taking the front bumper off.
