Why is my Fujitsu Air Conditioner not cooling or heating properly?
- SShannon RodriguezAug 8, 2025
If your Fujitsu Air Conditioner isn't cooling or heating well, several factors could be the cause. Start by checking if the air filter is dirty. Also, ensure that the intake grill or outlet port of the indoor unit isn't blocked. Verify that the room temperature is adjusted appropriately and that no windows or doors are left open. Consider whether direct sunlight is shining into the room during cooling operation, or if there are too many people, computers, or heating apparatus operating in the room. Check whether the fan speed is set to 'QUIET' or if the OUTDOOR UNIT LOW NOISE mode has been set. Finally, determine whether you have a Demand Response arrangement with your electric company.
