Why is my Fujitsu ASU9C1 not cooling well?
- Ffrederick40Jul 26, 2025
Several factors can impact the cooling performance of your Fujitsu Air Conditioner. Ensure the air filter is clean and that the intake grille or outlet port aren't blocked. Check if the room temperature settings (thermostat) are correctly adjusted. Also, make sure no windows or doors are open, and bright sunlight isn't entering the room. Other factors include the presence of heating apparatus, computers, or too many people in the room. Finally, check if the unit is set to SUPER QUIET operation.
