Why is my Fujitsu Inverter Halcyon 9332280012-03 not cooling or heating properly?

Several factors can cause poor cooling or heating performance in your Fujitsu Air Conditioner. Check the following: * Ensure the air filter is clean. * Make sure the intake grille or outlet port are not blocked. * Verify the room temperature settings (thermostat) are correctly adjusted. * Close any open windows or doors. * For cooling, close curtains to block bright sunlight. * Reduce heat-generating appliances or the number of people in the room. * Check if the unit is set to SUPER QUIET operation.
