The air coil is leaking refrigerant. There is oil residue in the condensate pan inside the blower compartment. Customer approved the repair to replace the air coil and filter drier. Unfortunately the unit is out of warranty. I completed a parts order form and a customer follow up form. As a courtesy I charged the unit to hopefully last until the coil arrives. Customer paid $1263.95 today and the same amount due upon the completion of the work.
