Why is my Fujitsu Air Conditioner cooling or heating poorly?
- MMr. Darin GriffithAug 16, 2025
Several factors can cause poor cooling or heating performance in your Fujitsu Air Conditioner: * Check if the air filter is dirty. * Ensure that the air conditioner’s intake grille or outlet port are not blocked. * Verify that you have correctly adjusted the room temperature settings (thermostat). * Make sure no windows or doors are open. * If cooling, close curtains to block bright sunlight. * Reduce heat-generating appliances or the number of people in the room during cooling operation. * Check if the unit is set to QUIET operation.
