When the fan speed is set to 'Quiet' mode, the unit operates at a lower fan speed, which can result in less powerful cooling or heating, making the overall performance seem poorer.
Click steps to track your progress.
Check the current fan speed setting on your remote controller.
Change the fan speed setting to a higher level (e.g., Auto or a specific high speed).
Refer to page 5 of the manual for instructions on how to change fan speed settings.
