Best Quiet Window Mounted Air Conditioners 2020
2022 has become a great year for anyone looking for a quiet window air conditioner with many new designs making them quieter and more efficient than ever before.

One type is new units are built in a Saddle or U-shaped design that allows the noisy compressor to sit on the other side of the window.

Most standard window A/C units are square packages with the noisy compressor packed inside.

This makes standard units noisier mainly since the noisy components, the compressor and fan, are located directly inside the packaged unit.

In the past, these components have been wrapped in sound suppressant blankets to help quiet a unit down which does help greatly.

Many new units now place the noisy components outside the window, which greatly improves sound quality and lowers the noise level.

While the older style units still work great, they will make more noise.

Below are the best window A/C units we have found that make the least amount of noise.

What is the Quietest Window Air Conditioner on the Market?

Most would agree that the Haier Serenity Series is currently the quietest window air conditioner on the Market.

While there is always a debate as to the best of anything, the Haier Serenity Series has many added features to help it run quietly.

The main feature is the wrap around the compressor with a noise suppressant blanket.
What is the Quietest Window Air Conditioner on the Market
This helps to greatly reduce the noise level since the compressor turning on and off is the loudest part of an air conditioner.

Of course, there are many other good units, so be sure to read reviews on any A/C system before buying.

What Size Window Air Conditioner Will You Need?

Air conditioners are rated by BTU (British Thermal Units) for how much cooling power they have.

The BTU a unit outputs can be matched with the square feet of a room.

A chart can then be looked at to see what sized unit would work best for you.

To get the square feet of a room, measure the length by the width and multiply it.

For example, a room 20 feet long by 20 feet wide would be 400 square feet.

Once the square feet of a space is known it can be matched to an HVAC sizing chart.

Be sure to take into account how well a room is insulated as well as the climate.

Some climates are much hotter and may need a bigger unit to help keep a space cool.

Why Are Window Air Conditioners Noisy?

Window units come packed in a single case with all the working components built into them.

Since all the parts are built into a single case, including the noisy parts, some noise will always be heard.

Most standard home HVAC units are mounted outside on a roof or on the side of a home with air fed in through duct work.

This helps isolate the noise outside and keep the inside of a home much quieter.

There are also split system-type HVAC units that separate the loud parts outside and keep the quiet components inside.

How To Find the Quietest Window Air Conditioner Unit

The quietest unit can be found by measuring the Decibels or dB noise levels it makes.

Decibel is a measurement that is widely used to rate how loud something is.

For example, the average conversation is usually around 45-50 dB, while a train horn is around 150 dB which is very high on the noise level scale.

Most window A/C packages make levels between 40-60 dB, with the lower numbers much quieter.

When looking for a quiet unit, finding a unit that makes less than 50 decibels would be best.

How Long will a Window Air Conditioner Last?

Window air conditioners usually last between 5-10 years, depending on usage.

How long a unit last will depend on how much it is used as well as the climate.

A very hot climate such as the American southwest will make the unit work much harder compared to a unit in more moderate weather.

Also, build quality and installation can be a big factor for how a unit wears over time.

Installing a unit that is in place with brackets and levels will not wear out components as fast as a badly installed unit.

Most window air conditioners will be ready to be replaced after five years of moderate to heavy use.

Finding a quiet window-mounted air conditioner can be a challenge. Mainly since the noisy components, the compressor and fan, are located directly inside the packaged unit.

Since the compressor is located inside the unit and not outside, some noise will always be present.

With that said, some window air conditioners have less noisy compressors than others. A quiet window ac unit with low decibel levels is ideal for many reasons.

Window A/C units are not usually built to be the quietest since they are budget-oriented equipment meant to fill a gap in a cooling system.

How a unit is mounted can make a big difference in noise levels, with it needing to be level and on a sturdy platform.

If the package is not level, it will likely rattle more and cause more noise than it would otherwise.

How well a unit is installed can also make an impact on noise level along with other factors. Read here for some tips on how to help quiet down a noisy window air conditioning unit.

Doing basic maintenance on a unit can go a long way in helping it stay running the best it possibly can.

Getting the most efficient unit is also a good idea with energy star certified, and energy efficiency ratio labels.

Basic care can also improve the life span of a unit which normally is around five years.

Things such as cleaning the air filter and keeping the outside air fins clean of debris can also make a unit run smoother.

Keep in mind to get a truly quiet unit, there other ways that are affordable such as mini split systems that separate the compressor outside and feed lines into a home that circulates refrigerant to a blower motor.

Split systems require more effort and skill to set up but are not as expensive as traditional central air conditioning systems used in homes.

I always recommend looking at a mini split system since they are very quiet, low-cost to operate, and built to last.
The Top Quiet Window Mounted Air Conditioner Reviews 2017
Mini-split systems are basically the same as a big home unit, only on a smaller scale.

They are very quiet and about as close to silent as an HVAC system can be.

They are also perfect for the DIY type of person, with many DIY kits available.

Of course, they require more skill to set up and require some basic construction skills such as using power tools and wiring.

When you are buying a quiet air conditioner window AC package, be sure to read online reviews to make sure it does have low decibels.

There are no completely silent window air conditioners available, but there are some that make the least amount of noise possible.

BTU capacity will also need to be considered to size the unit to the space that needs to be kept cool.

There are also ways to keep a window air conditioner quieter, such as making sure it is mounted correctly and bolted in place well.

Lowering the speed setting can also help to reduce the sound and keep a low noise.

    The way a unit is mounted and installed can make a big deference in noise levels. Be sure the package is level and has sturdy mounting brackets. Also cheap foam insulation on the side and top of the unit can do wonders.

  2. Bobbe

    After reading numerous reviews I decided on the Haier Serenity Series an haven’t been disappointed. I saw a episode on PBS this Old House about the units and made the dive. The picture they have in their ad with the baby sleeping next to the AC unit is a bit exaggerated but it is the quietest unit I have ever used. If you need a quiet window air conditioning unit than do yourself a favor and get a Haier. LG also makes reasonable low noise units which I use in other rooms, for the main living area though I use a Haier, best decision I ever made.

  3. Martin Dennis

    I have a question. Is it better to get an oversized unit that can keep up with demand on low or to get a smaller unit that would need to be ran on high more of the time. Specifically in regards to noise level.

    1. David

      Im also interested in this question. Hope someone has an answer.

      1. Marianne

        Hi, I’ve found the internet links which give you the calculations for the room have always worked for me. I googled “what size window AC do I need?” because I have a living room open to the kitchen and wanted to make sure everything stayed cool. I learned you have to add 4,000 BTU onto the recommended size just for the kitchen! So, it’s been helpful and has worked for me. I’m currently shopping for the bedroom and I read if two people usually use the room you add 600 BTU for each person. So these are things we don’t think of. Recommendations will give you a BTU range so I would stick with that and use your judgement but I wouldn’t go over the recommended range for the particular room you are cooling. Instead, try setting your AC on 72-73 degrees at the beginning of the hot season and just forget it! Turning the unit on and off uses more electricity than you realize. Trust me, I was skeptical but I tried it for one month and have never looked back. I leave mine on Energy Saver mode and come home to what feels like central air. Stay Cool!

        1. Bill

          An over-sized unit will turn on an off more which can run up electrical cost. Air conditioners draw the most power when they start with big amperage pull. Once they are running the amps level out and go down. An over-sized unit that cools a room quickly will tun on on off more often which in some cases cost more to operate. follow the chart in the post above to get the best sized unit for your room. If you live in a very hot climate you may go slightly bigger to help with a bit more cooling power.

    I had read a long time ago that if only manufacturers would spend a few more pennies to replace the stamped metal fan blades with less turbulent well designed plastic blades, window ACs could be much quieter and more efficient. I guess with Haier it finally happened! ALSO – just a guess (I read a comment about required length of the tube), but maybe also those rubberized loops are to prevent resonance or other vibrations transmitting through the pipes. Otherwise, why the rubber? I had an AC that was making a lot of buzzing and it turned out they had cheaped out and hadn’t fastened the thin refrigerant tubes anywhere with foam (as the repair guy told me was normal practice).

  5. Dave

    What is the average life expectancy of all of these units? Thank you´╗┐

    1. Bill

      Most window AC units are built to last 4-5 years, of course build quality and how hard they are used should also be factored in.

  6. Peter

    I have the LG 8,000 BTUs – it’s loud. Bought a Friedrich’s 14,000 and it is significantly quieter. I always stay away from Frigidaire.

    1. bill

      Are you saying that Frigidaire a/c’s are loud or generally lacking in quality ?

  7. Mary Shelly

    I just wanted to add that a fan on the high setting should be used as a reference for what is a normal sound level. The compressor noise should be about the same or quiet. I had a unit that had a very loud compressor, If compressor is louder than the fan you have a noisy compressor and should return it.

  8. Jamie

    I bought and installed a Haier Serenity Unit and it is really quiet compared to my old Koldfront unit even on high. My only complaint would be it sticks out into the room more, about 5 inches. Otherwise great unit.

  9. Dave

    To get silent cooling a mini split is the best if you want quiet. A standard window shaker or through-the-wall unit with the fan and compressor in the room with you will not be quiet.

    A split system with the condenser away from windows or doors away from you is the quietest installation possible.

    1. Maria

      How much do they cost? Can you give an example of a good mini split ac unit?

      1. Bill

        Cost range from $600-$3000 dollar or more depending on the type bought.
