Perform tuneup on AC system. Inspected indoor and outdoor coils, flushed drain line, replaced air filter, inspected blower wheel, checked temperatures, checked static pressure, checked refrigerant pressures, inspected all major and minor electrical components. Found biological growth buildup on blower wheel and evaporator coil, there is no surge protection on system, And compressor has high startup amps. Gave client solutions for issues with system, however, system is 8 years old and recommend replacing due to age and cost of repairs. Client needs to review all options with daughter and will follow up next week. Cycled and tested system, all operations OK at this time.
