Performed tuneup on air-conditioning system. Cleaned indoor and outdoor coils, flushed drain line, inspected blower wheel, checked temperatures, checked static pressure, checked refrigerant pressures, inspected all major minor electrical components. Found biological growth built up blower wheel and inside air handler, air handler is very rusty and insulation is compromised, compressor has high startup amps. Give client solutions for issues with system, however, system is eight years old and recommend replacing due to age and cost of repairs. Client wants to review estimate and go over everything with spouse. Should have decision by the end of the week. All operations OK at this time.
