Upon arrival, was informed that the house is being sold and that a maintenance precision tune up is required and outdoor suction line insulation needed replacing. Quoted to perform a precision tune up and quoted to replace insulation foam by the outdoor unit initially, homeowner agreed. Homeowner showed me to the system in the garage and condenser unit is on the side of the house. I pulled off the panel door to the indoor unit and inspected all electrical components connections inside the air handler, collected amp draw and voltage readings off electrical equipment, and check the unit for cleanliness. The air handler unit has accumulated growth and will continue to get worse. Recommend installing a Germicidal Ultraviolet Light System to help keep the unit clean and produce better indoor air quality. The evaporator coil is starting to get dirty and blower fan wheel has started to get dirty. The temperature split is 19 degrees in cool mode and within normal range. Found run capacitor for
