Arrived on site for a 1 system home care. Mr. Massee stated the system has been struggling to cool properly and the upstairs has little air flow going into each room. The system was running when we arrived and the temperature was set for 69 degrees. We began our inspection starting at the outdoor unit. We checked all electrical components and those are all in the desired tolerance range. We checked refrigerant pressures and found them to be off. The condenser coils were extremely impacted with dirt, debris, and the inside had about a foot layer of leaves, dirt, and debris. Next we inspected the furnace and found the blower wheel impacted with dirt and debris. There is evidence of biological growth forming on the condensation pump tubing, outside of evaporator door, and along the pvc drain line. The unit is producing a lot of condensation due to improper sealing along evaporator door, improper size of duct work, along with rips and tears throughout duct work. The ducts start at the base
