Arrived for EVal System was working but customer was wondering why system wasn’t keeping up Looked at both units. Blower was super dirty and had bio growth on it, evap coil was super caked up, out side unit was super dirty and the frigerant was r22 and at 20 degrees and low. Recommend evap coil replacement, blower clean and charging system to running specs. Relayed information to customer and discussed the recommendation and about getting a new unit. Customer is busy this week with doctor appointments but would like a call back to get a comfort advisor on 4/19/24 to set up an appointment.
