Found low Voltage control wire disconnected at outdoor condenser. Billed homeowner for reconnecting wire. Found system running without a filter. Blower motor access door was not screwed in or sealed properly. Had to remove a screw that held the Plenum to the furnace door housing so that the door could be sealed flush properly after diagnostics. Cooling draining properly again at this time but minor repairs needed. Sent estimate for repairs to be made by adding adhesive spray/tape to secure inner liner of insulation blower motor housing. As well as Arma flex to be sealed/taped on the Copper on 6 feet where it meets evaporator coil housing.
