Why is my Fujitsu UTY-LRHYM Receiver's cooling performance so poor?

If your Fujitsu Receiver isn't cooling or heating well, start by cleaning the air filter. Make sure that the air conditioner's intake grille or outlet port isn't blocked. Also, double-check your room temperature settings and ensure all windows and doors are closed. If it’s cooling operation and sunlight is entering, close the curtains. Reduce the number of heat-generating devices or people in the room and check if the unit is in QUIET operation.
