Upon arrival found that the outdoor exhaust removal system and the Voltage enhancement system has failed. After speaking with the customer customer chose gold option allowing me to rebuild the outdoor electrical control panel, replace the exhaust removal system, and return at a later date after ordering parts to perform extensive cleaning as well as to replace the outdoor exhaust removal fan blades. System was slightly low on refrigerant due to customer being a good customer and choosing a top option I went ahead and recharged the outdoor unit back to factory specifications. (Adding the refrigerant is not included in the 18 month warranty) everything else done it covered. System is cooling properly at this time.
