Performed tuneup on AC system. Cleaned 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. Recommend installing air purifier to help with allergies and eliminate odors in home. Also outdoor capacitor was weak, compressor had high startup amps, and there was no surge protector on outdoor unit. Got approval from client to replace outdoor capacitor, install hard start kit to reduce compressor startup amps, and install a surge protector on condenser. Cycled and tested system, all operations OK at this time.
