No cooling, did a complete evaluation of AC system. Found system low on refrigerant which means there is a leak in system. Also found biological growth buildup on evaporator coil, condenser coil is dirty, and compressor has high startup amps. Gave client solutions for issues with system, however, system is 10 years old and recommend replacing due to age and cost of repairs. Client needs to look over options and will follow up tomorrow to answer any other questions that they may have.
