Frequently asked questions about the Best Quiet Window Air Conditioner
Very / Ultra / Extra / Whisper quiet window air conditioner: what can I expect?
First, there is no such thing as a silent window air conditioner.
However, some window air conditioners make so much noise that sleeping or simple tasks such as listening to music becomes almost impossible.
In fact, before settling on any particular window AC, you should first ascertain whether you can tolerate the level of noise that it emits. To check how loud the unit is while it is running, check for the decibel (dB) rating label. The lower the dB rating, the quieter the AC is.
For guidance, humans can only hear sound from 140dB and lower. Sound higher than those values is bad for your ears and not recommended. Most conversations will produce 50 t0 60dbs of noise while vacuum cleaners are higher at 75 to 80 decibels.
Most of the noise comes from AC fans and the compressor. Movements and rotations from these compartments cause vibrations and can become a nuisance. However, if proper engineering is done, most of these noises and vibrations can be suppressed and muffled to tolerable levels.
Proper internal engineering mechanisms can ensure air is circulated more efficiently and there is no drag on the flow of air allowing whisper quiet cool air production.
On the low setting, some window ACs are very quiet will go as low as 40dB which is a gentle hum and is not likely to affect many users. Those covering large spaces are, however, likely to range between 50 – 60dBs.
Why is a window air conditioner better?
Window air conditioners are both more efficient and quieter when compared to their portable counterparts.
With a portable air conditioner, the whole appliance is placed inside the house and therefore there is no way to make the noisiest part face outside. It is easier to ensure sections that produce the most noise face outside the house and this can greatly reduce the noise emitted by this appliances.
Also, since window units are fastened on windows, noise resulting from vibrations may not be as vigorous as it would be in a portable AC.
How can I quiet noisy window air conditioner?
Purchasing and installing a window unit is only the easy part. Maintaining the appliance to ensure it is always operating on optimum conditions is where the real challenge comes at.
However, some simple steps can help you ensure you troubleshoot most of the main causes of excessively loud noises.
Check for foreign objects. If your appliances suddenly become excessively loud, it is possible some foreign objects have made their way into the appliances. Flying debris may be sucked into the machine while it is on. Use a flashlight to check for these after unplugging and opening the front grill and remove them.
Due to numerous moving parts located inside the unit, the vibrations produced by loosened the screws with time. A few turns with your screwdriver can solve this problem.
Be sure to also check the lubrication on the motors as they could produce a grinding noise and oil them if necessary.
How do quiet window air conditioners work?
Apart from proper engineering to ensure smooth movement of air inside the machine to avoid drag, placement of different compartments may also have an effect on the noise level.
An example is the mini-split window AC which, despite requiring more effort and skill to set up, produces much less noise by separating the compressor with other parts by allowing its placement outside.
