The Models That Have Made Our Best Quiet Window AC List

By undertaking an extensive review of the market for you, we’ve been able to determine those better performing AC units.

Furthermore, our results are the models that claim to be quieter performers. Therefore, they are ideal for use where sound levels need more consideration.

However, as well as carefully considering the decibel figures of such models, we’ve also assured that the overall construction and design of each AC unit here is just as advantageous.

Each quiet window AC unit listed here can be installed with ease, with each one offering several fantastic features as standard.

However, we’ve also looked toward the many verified customer reviews of each model when deciding upon our top seven. These are the models that have been well received by those looking for a quieter running AC model to install in the home environment.

Seven of the Best Quiet Window AC Models on the Market

Top of our list here and best pick of the bunch is the Haier ESAQ406T. This gets our vote for perhaps one of the quietest of AC window units on the market.

Bests of all, this model comes complete with a compressor blanket. This works hard to ensure all sound is reduced when the unit is in operation.

Operating at just 43 decibels when on its lowest setting, the noise here resembles more of a fan than a rumbling compressor! Thus, you can cool up to 250 square feet of a room without disturbing others.


A dual notion design, the Haier boasts an energy-saving setting, dehumidify mode, sleep mode, auto cool, cross-flow fan, and on/off timer. It also comes with a remote control for easy access.

Well designed and constructed this model may be slightly more expensive than others on the list, but in drastically reducing the noise level, customers find the extra cost worth it.

Another Haier model, this is the ESAQ406P and a close runner up to our editor’s choice above. Yet again, this is the model which we believe also works as one of the quieter of window ACs on the current market.

This model also operates at 43 decibels and cools rooms of up to 250 square feet in total.

However, with that all-important compressor blanket as part of this makeup, this actively reduces noise to create less of a disturbance in the home environment.

With similar features to that of our top pick, the ESAQ406P boasts of a 24 hour on and off timer, a dehumidify mode, a sleep mode, an energy-saving mode, and a fully functional remote control.

Featuring the most intelligent of designs, many customers also highly rate the look of this unit when used in the home.

Next up on our list is a fantastic budget buy unit from LG. The LW6017R may be one of the cheaper quieter window AC units here, but it can still rival those more expensive units with its impressive features.

With the ability to cool rooms up to 260 square feet in size, this unit comes with a full installation kit, a fully functioning remote control, three fan speeds, three cooling speeds, and a full anti-corrosion protection!

Most importantly, providing a noise level of just 52 decibels, this updated LG model continues to operate quietly in performance.


Many satisfied customers claim that they can set this AC unit to run throughout the night and not be disturbed throughout.

With quick, straightforward installation, this unit is easy to operate and has an on and off timer element and a fantastic energy-saving function.

For those rooms that require a little more power, the Frigidaire is our selection for those medium-sized rooms. This FGRQ0833U1 model works to cool spaces of up to 350 square feet.

However, this model also catches our attention for the many verified reviews claiming it as one of the quietest AC units people have bought.

Thus, many claim it’s an ideal choice for rooms such as offices and bedrooms, meaning less distraction. It’ s also considered the best unit for leaving on throughout the night time.

This reduction in noise could well be due to the Frigidaire’s fantastic innovate design. Here, specially constructed louvers move the air into and out of the unit in a circular motion. This results in a most effective but ultimately quieter operation.

At just 44 decibels, this is an energy star rated product and even features an ionizing air filter.

Packed full of additional features the FGRQ0833U1 also encourages complete control through a remote control, built-in timer, as well as three fan speeds.

Our second LG model on the list for review here is the LW8016ER model.

Another ideal solution for those medium-sized rooms, this is the unit that provides cooling relief up to 340 square feet in total.

Though not whisper-silent as such, at just 54 decibels, it’s claimed by many satisfied customers as a quieter runner than similar market models.

This makes it ideal for use in areas such as the bedroom whereby it won’t disturb sleep, or areas requiring a good level of concentration such as home offices.

Functioning as an energy-saving unit, this AC offers the use of remote control for easy access around the home. It also benefits from a protective anti-corrosion coating.

An easy model to install, this LG AC unit boasts extra side panels. This encourages the unit to block out more hot air in operation. These are supplied with the unit as additional, so you can apply them as and when needed.

Our third and final LG model on our review list here is the LW1216ER AC unit. This makes our top seven as one of the best AC units for those larger rooms.  

Working to cool spaces of up to a staggering 550 square feet in total, what impresses us most, though, is how it does all this quietly!

Gaining some fantastic customer reviews on its quieter operation, this has a noise level of just 52 decibels.

Complete with a fully functional and indeed stylish remote control, this is the more convenient of larger units but one that is also the more durable. Built to last, this LG unit benefits greatly from an anti-corroded gold finish coating.

Installing this unit upon delivery is also hassle-free, with a full installation kit included.

Boasting a more attractive and modern look for that of other larger AC units, the LG has a good energy efficiency ratio of 12.1 and also offers the use of an on and off 24-hour timer as standard.

We end with our most impressive of quieter AC Units. Last on our list is the Koldfront WAC25001W.

We’ve included this fantastic model here because though it’s the largest on the list, the WAC25001W works unbelievably quiet in a large room when on a low setting. This lower setting is also a more energy-saving choice, as well.

At just 64 decibels, this unit cools spaces of up to an amazing 1500 square feet!

The many additional features this model offers is also impressive. Here you can access four-way louvers, adjustable speeds, sleep, dry and energy saving modes, a 24-hour timer, a remote control, a washable filter, and even an indicator warning you when the filter needs cleaning!

Boasting of a most impressive performance, all the while working on reducing the volume as it does so, the Koldfront comes complete with all necessary parts. This means you can have it up and running in no time at all.

Finding the Best Quiet Window AC Unit for Your Needs

Before you make your final choice, we suggest making sure your chosen AC model is the quieter running model for your needs.

Therefore, before parting with your money, consider ways you can ensure the best cooling experience possible, including:

  • Keeping a check on the AC units power cord – Damaged power cords mean the machine can struggle in operation. This leads to vibration and intermittently stopping throughout.
  • Ensuring the filter is kept clean and operational – Those AC units operating with dirty filters will often sound louder in performance. Therefore, aim to keep this area regularly cleaned, or look to those machines which indicate when this process is required.
  • Consider the placement when installing your AC unit – Another great noise contributor with an AC unit is incorrect positioning. Many of these appliances come complete with accessories that work to deaden noise. Yet, if these become worn and need replacing, they will encourage a noisier operation. Likewise, if an AC unit isn’t correctly installed, it will vibrate, hum, buzz, and make a loud rattling sound throughout.
  • Double-check all moving parts of the unit – Some mechanical parts which aren’t in place correctly have the potential to run against the unit and make a most irritating noise! Regularly ensure all parts are correctly attached and consider lubricating them to ensure they run smoother.

Frequently Asked Questions

Are bigger AC window units louder?

Unfortunately, the larger the AC until, the more sound it has the potential to emit. This is because those bigger models have to provide more power in their operation. But this is what increases noise levels.

However, with recent improvements in such technology used in AC units, many models now work hard to reduce increased sounds. One of the ways bigger machines run quieter is when used on low settings. Better still, these low settings are typically the energy-saving selections!

Why do people look for quieter AC window units?

Quieter AC window units are favored greatly by those looking to cool their bedrooms as they sleep. Therefore, this is a time when the noise level is a big consideration. Though a small amount of humming and white noise is okay for some, the loud droning effect and incessant humming will simply keep people awake.

So, by selecting a model that claims to work hard to reduce such noise levels, sleep is more comfortable as a result. Likewise, for those looking to put an AC unit into an office environment, increased noise levels will distract workflow – so quieter machines are more effective here.

Our Final Thoughts on Quiet Window ACs

In concluding, though the Haier ESAQ406T gets our editor’s choice for best quiet window AC, we believe all seven of these models are worthy contenders for the title.

Each model discussed here actively works to reduce the level of noise throughout the operation. Therefore, each one of these window AC units are an ideal choice for those looking to find a quieter cooling solution.
