Car AC systems fail in a few predictable ways: a slow refrigerant leak, a compressor that's stopped engaging, a condenser punctured by road debris, or an actuator that's stuck sending air to the wrong place. All of them can be diagnosed and most of them repaired on-site by a mobile mechanic with the right equipment.
The right equipment is the key phrase. A can of refrigerant from the parts store treats the symptom, often overcharges the system and ignores the leak. Professional mobile car AC repair means recovering what's in the system, pulling a vacuum, finding the leak with dye or an electronic sniffer, fixing it and charging by weight to the exact spec.
