Causes of noise on air conditioners
Physical noise is the vibration of sound waves with different intensity and frequency, arranged in no order and propagated in an elastic medium, the unit of measurement for noise is dB (decibel).
Sound intensity from 90 – 140 decibels will affect hearing. Scientists set 100 decibels as the highest safe limit of sound intensity.
Many studies prove that noise of 35 decibels or more is enough to cause disturbances to normal sleep. If the noise of your air conditioner is affecting your sleep every day, you need to find a way to fix it right before everyone’s health is affected.
Old air conditioners often make noise if not properly maintained, but there are other causes of this problem such as:
The wall where the air conditioner is installed is too thin or uneven, it is also likely to cause noise for the air conditioner to operate. To overcome this, you can put an extra pad behind the air conditioner to reduce noise.
In addition, it should be noted that both the hot unit and the indoor unit of the air conditioner should not be installed opposite each other on one wall. The acoustic resonance from this incorrect installation will make the noise even more annoying.
When using the air conditioner, but the air conditioner makes too much noise, perhaps the outdoor unit’s radiator fan is broken or stuck and will not be able to rotate easily and balance. At such times, the air conditioner will make noise.
Dirt and dirt stick for a long time on the filter mesh and heat exchanger, leading to blockage, the air flow is not circulated. Therefore, the system becomes vibrating and increases the noise level when operating.
2.4. Screws and accessories on the air conditioner are loose
During installation and maintenance, there will be some screws that may not be tightened or installed in the wrong position compared to the original.
After a period of use, the screws loosened, causing the case to vibrate, collide with each other during operation and cause the air conditioner to make noise.
In principle of installation: The outdoor unit and the indoor unit need to be placed as far apart as possible, usually the maximum allowable length of an air conditioner is about 15m (can be up to 30m depending on the model).
Users should regularly clean the air conditioner during use (from 4-6 months).
Cleaning the air conditioner not only helps the air conditioner operate smoothly, check the certainty of the screws, but also ensures hygiene and health for the family.
