Why is my Fujitsu Air Conditioner not cooling well?
- TThomas HicksAug 15, 2025
Several factors can affect the cooling performance of your Fujitsu Air Conditioner. Check if the air filter is dirty, or if the air intake or outlet is blocked. Ensure the thermostat is set correctly and that no windows or doors are open. If it's during the day, close the curtains to block direct sunlight. Also, consider if there are too many heat-generating devices or people in the room, or if the unit is set to SUPER QUIET operation.
