How To Choose The Quietest Small Room Air Conditioner?
Check The Decibel Rating
Any air conditioner rated under 60 decibels is arguably quiet.
Look to the decibel rating of the AC to get its noise level as well as to compare it with other models. Besides, here are features that influencing on the noise level of an AC:
Symmetrical Design
A symmetrical air conditioner prevents rattling noise caused by vibration.
Airflow
The airflow of an air conditioner is measured in cubic feet per minute, which shows the total amount of cool air releasing to the outside per minute.
The higher the CFM rating, the higher the noise level.
If you want a quiet AC for a small room without compromising cooling effects, choose a model with high cooling – low airflow.
Type Of Compressor
There are two types of AC compressors: rotary compressors and inverter compressors. The second type is considered to be quieter because it doesn’t kick in with a noisy thumb. In comparison, inverter compressors are 3-6 dB quieter than the other.
Other Features
But take note that low decibel rating isn’t everything! There are a lot of small-room air conditioners at an incredibly low noise level but short in lifespan and insufficient in cooling effects, which is not a good buy at all.
Therefore, you should consider some other features, aside from noise level, when considering a small-room AC.
Power Output
Small rooms are varied in area and there’s no universal air conditioner for all of them.
Picking a too-small AC for your room will force it to overwork, which shortens the lifespan and increases the noise. Therefore, it’s worth measuring your room carefully plus checking the insulation level of the space to find a model with the right power output.
Below is rough estimation of the small-room AC’s power required for a specific room size:
Room size (square feet) | AC Power Output (BTUs) |
600 | 18,000 |
500 | 15,000 |
400 | 12,000 |
300 | 9,000 |
200 | 6,000 |
But we recommend choosing a bigger capacity air conditioner for quieter operation if your budget is available. Why?
Suppose that you need to cool down a 300-square-foot room. According to the table above, you would buy a 9,000 BTU air conditioner with 52-55 decibels of noise level. It’ll emit 56 decibels as you’ll run it at high speed.
But when switching to a 10,000 BTU model with 53-58 decibels of noise levels, the unit is capable of cooling down the room at low setting, emitting 53 decibels.
Energy Efficiency
Why not choose a small-room AC that’s both quiet during operation and energy-efficient? The cost is unnoticeable, by the way.
A model that’s at least 10 EER rated is considered energy-efficient.
