Why is my Fujitsu Inverter Halcyon ASU9RL Air Conditioner cooling poorly?
- AAndrew AvilaJul 29, 2025
Several factors can cause poor cooling performance: * Check if the air filter is dirty. * Ensure that the air conditioner's intake grille or outlet port isn't blocked. * Verify that the room temperature settings (thermostat) are correctly adjusted. * Make sure no windows or doors are open. * If it's during cooling operation, close curtains to block bright sunlight. * Consider if there are too many heat-generating devices or people in the room. * Check if the unit is set to SUPER QUIET operation.
