Why is my Fujitsu ABT18RG Air Conditioner not cooling or heating well?

Why is my Fujitsu Air Conditioner not cooling (or heating) properly? Check if the air filter is dirty, or if the air conditioner’s intake grille or outlet port is blocked. Ensure that you have correctly adjusted the room temperature settings (thermostat). Make sure no windows or doors are open. If cooling, check if sunlight is entering the room and close the curtains. Also, consider if there are heating devices, computers, or too many people in the room.
