AC precision tune up. Clean and tune up AC; cleaned condenser coil, checked all outdoor electrical components, tested indoor air flow, checked refrigerant levels, and tested overall AC operation. Would recommend vent screens, this will prevent cridders from entering furnace. Would recommend drain pan treatment, this will prevent biological growth inside cooling coil. Would recommend a surge protector to prevent damage to ac if a power surge occurs. Lastly would recommend start assist, this gives a jumpstart to compressor when turning on, allows compressor to last longer. Customer would like to hold off on additional services at this time.
