Arrived at location, customer complained the downstairs ac was not keeping up. Checked refrigerant pressures and found them to be low. Checked for leaks in the evaporator coil and found leak in the front of evaporator coil video included in invoice. Found unit pitch to be off. Unit will need to be properly leveled to avoid drainage issues. Drain pan is rusting out. Drain on need to be replaced to prevent water coming through the ceiling in the event of a clogged drain line. There is not enough return air on the downstairs unit causing stress on the components. Noticed primary and secondary drain lines are loose and will need to be tightened when we do the repair ( drain lines built by adon). Created estimate for coil replacement as well as a new drain pan, and additional return. Unit turned off at attic switch for now. Spoke with Jessie who is going to call the customer around 2-2:30 for discussion about unit replacement.
