Homeowner had us out today because their second floor system is not cooling properly. Upon arrival, homeowner informed us that they noticed a lot of water buildup in the emergency drain pan and sometimes the refrigerant lines will freeze over. We checked airflow and found that the filter was regularly changed and no restriction. We checked refrigerant pressure and noticed that the system was extremely low on refrigerant indicating a leak within the system. We found a leak to be at the evaporator coil. We also noticed that the 40/3 capacitor was out of range and needed to be replaced. The outdoor coil was very dirty and would recommend cleaning. We Attempted to get homeowner financed which was declined at this time. They will call back at a later date to schedule repairs. We also noticed some biological buildup in the inside of the system and recommended to install UVC.
