Complete 2 system a/c repair and preventative maintenance check. No cool main system. Found system low on freon found a leak at the evaporator coil. Found compressor draws high amps with high head pressure. Found mold inside the supply box. The system is old and needs to be replaced. The condenser coil is dirty and needs to be chemically clean, declined maintenance plan. The system needs a hard start kit to reduce stress on compressor, owner decline. Added 2 lbs of Freon to the system, the system is cooling at this time but can compressor can trip on head pressure do to the dirty coil and extreme heat
