To Next PageTo Next PageWhy is my Haier Air Conditioner cooling poorly?
Poor cooling in your Haier Air Conditioner can be due to several reasons: a dirty air filter (it should be cleaned every 15 days), obstacles blocking the inlet or outlet, incorrect temperature settings, open doors or windows, direct sunlight entering the room (use curtains), or too many heat sources or people in the room.
What to do if my Haier AS09/12GS2ERA Air Conditioner is making noise?
A swishing or gurgling noise during or after operation is normal, caused by refrigerant flowing in the system. This is more noticeable in the first few minutes after starting. A cracking noise during operation is also normal, caused by the casing expanding or shrinking due to temperature changes. However, if there's a loud noise from airflow, the air filter may be too dirty.
Why does my Haier AS09/12GS2ERA Air Conditioner smell?
The Haier Air Conditioner might be circulating smells from the room's interior, such as odors from furniture, paint, or cigarettes.
What to do if my Haier Air Conditioner blows out mist or steam?
During COOL or DRY operation, the Haier Air Conditioner may blow out mist due to the sudden cooling of indoor air. This is normal.
Why can’t I change the fan speed in dry mode on my Haier Air Conditioner?
In DRY mode, when the room temperature becomes lower than the set temperature plus 2 degrees Celsius, the Haier Air Conditioner will run intermittently at LOW speed regardless of the fan setting.
