Why is my Haier HSU-05LEA03 Air Conditioner cooling poorly?

Courtney Meyer PhDAug 18, 2025
Poor cooling in your Haier Air Conditioner can stem from several factors. Check if the air filter is dirty and clean it if needed, as it should be cleaned every 15 days. Ensure there are no obstructions blocking the air inlet or outlet. Verify that the temperature is set correctly and that all doors and windows are closed. If direct sunlight is entering the room, use curtains to block it. Finally, reduce the number of heat sources and people in the room.

Several factors can impact the cooling performance of your Haier Air Conditioner. Check if the air filter is dirty and clean it every 15 days. Ensure there are no obstructions blocking the inlet and outlet. Verify that the temperature is set correctly and that all doors and windows are closed. Direct sunlight can also affect cooling, so use curtains. Finally, consider if there are excessive heat sources or too many people in the room.

When your Haier Air Conditioner is stopped, it won't restart immediately for about 3 minutes. This is a protection mechanism for the system. If the electric plug is pulled out and reinserted, the protection circuit will activate for 3 minutes to protect the air conditioner.

Matthew NelsonAug 28, 2025
Your Haier Air Conditioner may produce noise for several reasons. A swishing or gurgling sound, especially noticeable in the first few minutes of operation, is normal due to refrigerant flow. A cracking noise during operation is also normal, caused by the casing expanding or shrinking with temperature changes. However, a big noise from airflow could indicate a dirty air filter, which needs to be checked and cleaned.

If your Haier Air Conditioner doesn't restart immediately after being stopped, this is normal. The unit has a built-in protection feature that delays restarting for 3 minutes to protect the system. If the electric plug is pulled out and reinserted, this protection circuit will also activate for 3 minutes. Wait for 3 minutes before attempting to restart the unit.

Your Haier Air Conditioner might produce a swishing or gurgling noise due to refrigerant flowing in the system, especially noticeable in the first few minutes of operation. A cracking noise can occur because of the casing expanding or shrinking with temperature changes. If there's a loud noise from airflow, the air filter might be too dirty.
