Responded to inadequate cooling. System was running when I arrived, proceeded to check pressures found suction side low but liquid side wasn’t bad, indicating poor air flow. Went to indoor unit and checked blower capacitor found capacitor low, replaced and fan was still running slow. Recommended changing fan motor and capacitor. While inspecting the system noticed biological growth inside the system recommended IAQ Equipment. Installed recommended equipment, started and tested system. System is now cooling properly.
