While some people might find the ambient hum of appliances in the background soothing, the vast majority don’t like the disturbance caused, finding it hard to ignore the noise. During summer or, if you live in a hot area all year long, you need to turn on the AC to feel comfortable in your home. However, you are likely not a fan of the annoying noise the appliance produces when it runs. If you find this to be an issue yet you still want to enjoy the cool, soothing environment and AC creates indoors, you are in luck as there are plenty of ultra-quiet window ACs out there, appliances that you can be in the same room with and not even hear them run.
Top 7 Quietest Window Air Conditioners Compared
1. Haier Serenity Series ESAQ406T
A silent AC that you are bound to love using as you won’t even be able to hear it run if you sit in the same room with it, the Serenity Series from Haier not only keeps quiet, but it provides a hearty 6000 BTUs to effectively lower temperatures and provide a comfortable ambiance in rooms of up to 250 square feet. It comes at a reasonable price that makes it affordable as opposed to most entries on this market. Design-wise, it is quite pleasing as it boasts clean lines that give it a modern feel. It measures 21.2 inches in width by 18.2 inches in depth by 12.4 inches in height and weighs 56 pounds, which makes it surprisingly light. Additionally, a 1-year warranty on parts and labor and a 5-year warranty for the sealed system is provided by the manufacturing company, so you are spared of spending money on repairs for a long while.
When it runs, the Haier AC produces only 43 decibels on the lowest fan speed, which makes it one of the quietest entries on its market. What makes it so effective when it comes to operational silence is the compressor blanket it features that is specifically included to reduce noise output.
There is a number of ways in which it allows you to customize its operation to your liking, but the one that stands out the most is the 24-hour timer that enables you to program the exact on/off times of the appliance. It also provides 3 cooling speeds and 3 fan speeds in order to personalize comfort as you please. Automatic cooling is included in case you want it to run freely and maintain an optimal cooling level without requiring your interference. The digital temperature adjustment allows you to pick what temperature should be maintained in the room you place it in. Another customization element worth mentioning is the 4-way air direction that allows you to direct airflow as you need.

Understanding Decibels Levels
The human ear can hear sounds ranging from 0 to 140 decibels, sounds that exceed this limit being painful for the ears. ACs are appliances that usually tend to get quite noisy, being distracting to sit in the same room with them while they operate. There are quieter models that produce from 50 to 70 decibels, some even lower than this, like the Haier Serenity Series ESAQ406T that produces only 43 decibels on the lowest fan setting. However, for you to properly appreciate how the AC noise level is rated, you first need to understand decibel levels as a whole. Here are a few examples of noise sources and their decibel ratings:
- 20 decibels: Normal whispering.
- 50 decibels: Quiet conversation at home.
- 60 decibels: Restaurant conversation.
- 70 decibels: Running a vacuum cleaner.
- 80 decibels: Running a garbage disposal.
- 100 decibels: Railway platform.
- 140 decibels: Jet engine down the runway.
Due to their design, window ACs tend to get louder than their regular counterparts as the compressor, which is the component responsible for producing the operational noise is not separate or outside the building. However, as you can see, there are some models that can remain silent while they operate, maintaining loudness comparable to a normal conversation you carry at home or at the restaurant.
If you need a silent ambiance where you spend most of your time yet you want to enjoy the cooling sensation of having the AC blow cool wind in the room, you are clearly in need of a silent model. As we have already established, the Haier Serenity Series ESAQ406T is the best selection from this point of view as it produces only 43 decibels when it runs. It can cover areas of up to 250 square feet, so you can rely on it for the office or living room, and its low energy consumption ensures you won’t be spending a ton of money when the utility bills come either. Another excellent option that is better suited for those who need an AC for a larger space is the Frigidaire FFRE1033Q1 that outputs only 52 decibels when it runs and can cool down temperatures in rooms and areas of up to 450 square feet. However, for those on the hunt for a budget-smart option, we recommend the hOmeLabs AC-188 that keeps quiet when it runs, comes at a great price, and can handle cooling the air in rooms of up to 150 square feet. It might not provide wide area coverage, but there are more than enough customers who don’t seek big coverage as they don’t need it, so its inclusion in our top was inevitable.
