Performed tuneup on AC system. Inspected indoor and outdoor coils, flushed drain line, checked air filter, inspected blower wheel, checked temperatures, checked static pressure, checked refrigerant pressures, inspected all major and minor electrical components. Found some biological growth buildup in air handler, there are no indoor or outdoor surge protectors, capacitor is weak, Compressor has high start up amps, and system is low on refrigerant. Gave client solutions for issues with system. Client chose solution #3 at this time. Replaced outdoor capacitor, installed hard start kit to reduce compressor startup amps, and charge system with 2 pounds of refrigerant. Client signed up for Mach one membership. Cycled and tested system, all operations OK at this time.
