Why is the cooling or heating effect not good on my Klarstein 10028189 Air Conditioner?

If your Klarstein Air Conditioner isn't cooling or heating well, start by pulling the curtains to block direct sunlight. Then, close any open doors or windows, especially if there are many people present or other heat sources during cooling mode. Also, inspect the filter screen for dirt and clean or replace it if necessary. Finally, ensure that the air inlet or outlet is not blocked.
