In San Antonio heat, warm vents usually mean low refrigerant from a leak, a compressor clutch that is not engaging, weak condenser airflow, a clogged cabin filter, or an electrical fault. Check the cabin filter and front grille, then schedule diagnosis at AAB Service on Nacogdoches Rd if cooling stays weak.
Read guideA recharge adds refrigerant; a repair fixes the reason the system stopped cooling. If your A/C is low, warm, or keeps losing cooling, diagnosis matters more than a quick top-off.
