1. How to Fix Unusual Loud Noise from Air Conditioner
An air conditioner making loud noises during operation is a common issue faced by many households. While not a serious malfunction, the loud noise can disrupt family sleep or relaxation time.
Imbalanced Air Conditioner Placement
During operation, the air conditioner vibrates significantly, causing screws to loosen over time. This leads to the unit banging against the wall, resulting in loud and unpleasant noise. Users simply need to tighten the screws, or seek assistance from a maintenance technician to thoroughly inspect the unit.
Dirty Fan Blades
If the air conditioner is not regularly maintained and cleaned, the fan blades will accumulate a lot of dust. This is a common cause of air conditioner noise and can also reduce the cooling efficiency of the unit. Users should schedule regular maintenance for the air conditioner or perform this task themselves. Modern air conditioner models are designed for easy cleaning and maintenance.
The steps are very simple; users just need to remove or lift the front cover of the air conditioner, then clean the fan blades, filters, and heat exchanger. After cleaning, not only will the noisy operation be resolved, but the airflow from the air conditioner will also be stronger and 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 in operation. To remedy this, users can insert a spacer between the air conditioner and the wall. Additionally, to avoid being disturbed by the noise from the outdoor unit of the air conditioner, users 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 on the same wall, the phenomenon of sound resonance between the two units during operation will create quite uncomfortable noise.
Cracked Air Conditioner Door
This is also a reason why the fan of the air conditioner makes loud noises when blowing. For small cracks, users can use specialized glue for repair. However, if the door has a fairly large crack, users should replace it with a new one to fix the noise issue and ensure safety during use.
Other Considerations When Using
While the air conditioner is running, if you hear water flowing, it may be due to condensation in the pipes. Users should call a technician for gas refilling, vacuuming, and blowing nitrogen. Additionally, when the air conditioner starts up or immediately after shutting down, if there is a cracking sound on the evaporator coil, users do not need to worry. This is a normal phenomenon caused by rapid temperature changes, which immediately expands the plastic casing of the air conditioner, resulting in this noise.
