Homeowner had us out today due to issues with both systems inside of the home. Upon arrival we noticed two systems both from 2019. Homeowner explained that one system is currently working in the other one only blows warm air. we checked both air handlers located in the crawlspace. We found that for the one that is currently somewhat working that there is a drainage issue in the homeowner took apart the current drain to try to figure out what the issue was. We found that the system was holding water and the inside insulation was extremely wet. Both of the systems rely on a gravity drain and we recommend installing two condensate pumps for better usage. We also noticed that both systems have tons of biological growth on the inside, reaching all the way into the ductwork. Both of the evaporator coils are dirty and will need to be clean because they are causing the system to struggle with airflow and affect the refrigerant pressures. for the system that was out of operation we found a 45/5
