Performed tuneup on AC system. Inspected indoor and outdoor coils, replaced air filter, flushed drain line, inspected blower wheel, checked temperatures, checked static pressure, inspected ductwork, checked refrigerant pressures, inspected all major and minor electrical components. Found biological growth buildup in blower cavity and evaporator coil, UV light is burnt out and not working in blower cavity and is in the wrong location, compressor has high startup amps, and outdoor capacitor is weak. Gave client solutions for issues with system, however, system is 6 years old and out of warranty. Recommend replacing due to age and cost of repairs. Cycling in tested system, all operations OK at this time.
