Why is my Fujitsu AST30 Air Conditioner cooling (or heating) poorly?
- Aalexander74Aug 14, 2025
Poor cooling or heating performance in your Fujitsu Air Conditioner can be due to several reasons: * A dirty air filter. * Blocked intake grille or outlet port. * Incorrect room temperature settings. * Open window or door. * Bright sunlight entering the window during Cooling operation (close the curtains). * Too many people or heating apparatus and computers inside the room during Cooling operation.
