Performed tuneup on AC system. Cleaned indoor and outdoor coils, flushed drain line, checked air filters, inspected blower wheel, checked temperatures, checked static pressure, checked refrigerant pressures, inspected all major and minor electrical components. Found biological growth buildup inside air handler, there are no indoor or outdoor surge protectors on system, And compressor had high startup amps. Gave client solutions for issues with system, client chose to go with a solution #4 at this time. Installed indoor and outdoor surge protectors and installed hard start kit to reduce compressor start up amps. Cycled and tested system, all operations OK at this time.
