1. Reasons and Solutions for Abnormal Loud Noise from Air Conditioner
Air conditioners often make loud noises during operation, which is a common issue for many households. While not a serious malfunction, the loud noise can disrupt sleep or relaxation time for families.
Imbalanced Air Conditioner Placement
During operation, the air conditioner tends to vibrate excessively, causing screws to loosen over time. This results in the unit banging against the wall, producing loud and unpleasant noises. Simply tightening the screws or seeking assistance from maintenance professionals to inspect the entire unit can resolve this issue.
Dusty Fan Blades
If air conditioners are not regularly maintained and cleaned, the fan blades can accumulate a lot of dust. This is a common cause of air conditioner noise and can also reduce the cooling efficiency of the unit.
You should schedule regular maintenance for your air conditioner or perform this task yourself. The air conditioners currently provided by Green Electronics are all designed for easy cleaning and maintenance.
The steps are quite simple; you just need to remove or lift the front cover of the air conditioner, then clean the fan blades, filters, and heat exchanger coils. After cleaning, not only will the noisy operation be resolved, but the airflow from the air conditioner will also be stronger and much cleaner.
Incorrect Air Conditioner Installation
If the wall where the air conditioner is installed is too thin or uneven, it can also cause noise when the air conditioner is operating. To fix this, you can insert a spacer between the air conditioner and the wall surface.
Besides, to avoid being affected by the noise from the air conditioner's outdoor unit, you need to install the outdoor unit on a separate wall from the indoor unit. If both the outdoor and indoor units of the air conditioner are installed back-to-back on the same wall, the phenomenon of sound resonance from these two units when operating will create quite unpleasant noise.
Cracked Air Conditioner Doors
This is also a reason why the air conditioner's fan will produce loud noises when blowing. For small cracks, you can use specialized glue to seal them. But if the doors have relatively large cracks, you should replace them to eliminate the noise and ensure safety during use.
Other Considerations When Using
When the air conditioner is running, if you hear water flowing, it's due to condensation in the pipes. You need to call a technician to recharge the gas, vacuum, and blow nitrogen. Additionally, when the air conditioner starts or just after it's turned off, if you hear rattling noises on the indoor unit, you don't need to worry.
This is a normal phenomenon caused by rapid temperature changes, causing the plastic shell of the air conditioner to expand immediately, resulting in this noise.
