The Top Quiet Window Mounted Air Conditioner Reviews 2017
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 in the unit and not outside away from the home some degree of noise will always be present.
With that said there are some window air conditioners that have less noisy compressors than others.

The best way to judge how noisy a window air conditioners will be, is to read real reviews from real people online.
Keep in mind to get a truly quiet unit there are other ways that are affordable such as mini split systems which separate the compressor outside and then 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.
Here are the top units we have found that make the least amount of noise.
As always be sure to read reviews on Amazon, forums, or elsewhere to be sure a unit is the right pick for you.
Our Picks for Best Quiet Window Mounted Air Conditioners

  1. Haier Serenity Series
  2. Haier Serenity Series 6,000 BTU 115V Window Air Conditioner with Ultra Quiet Sound Package

    Haier is known for making quiet heating and cooling units.
    This unit is a 6000 BTU, 115 Volt unit and uses what is called Cross Flow technology to keep the fan noise level down.
    The Haier company also wraps the compressor in a noise suppressant blanket that quiets it down.
    The compressor on any HVAC unit often makes the most noise and can be heard kicking on and off as it cycles. Having this component wrapped goes a long way in making a unit run quieter.
    The cross flow fan technology also makes the fan run smother and make less noise than conventional fans.
    A window unit will always make some noise but this may be the quietest unit available currently.

  3. Emerson EARC6RE1 Quiet Kool
  4. Emerson EARC6RE1 Quiet Kool 6,000 Btu 115V Window Air Conditioner

    Emerson has a new window A/C unit called the Quiet Kool EARC6RE1.
    It is built for easy installation, LED display, three speeds and a remote control.
    Emerson is a well known company with good warranties including 1 year parts and labor, 2 years parts and 5 years on the compressor.

  6. LG LW8016ER 8,000 BTU 115V Window-Mounted AIR Conditioner with Remote Control

    LG makes many good window A/C units including the 8,000 BTU LW8016ER.
    While it may not be the quietest on our list when mounted correctly it operates much quieter when compared to many other units.
    One of the things that make it have less noise is it has a rotary compressor which is quieter and more economical to operate.
    It is 115 Volt unit that is rated to cool 340 square feet of space.
    When it comes to price, along with a well built unit that is much quieter when compared to many other models the LG LW8016ER is worth a look.

  7. Friedrich CP10G10B
  8. Friedrich Chill CP06G10B 6000 BTU Window Air Conditioner

    Friedrich Chill also makes many good units including the model CP06G10B.

    The 6,000 BTU unit is rated to cool a space roughly 250 square feet depending how hot it is, and how well insulated the room is.
    When set to high cooling it does make noise and works best at lower settings for a more quieter unit.
    While not the quietest when comparing price vs. overall build, it may be a good option for a budget minded person looking for a good unit.

  9. Frigidaire FFRE2533S2
  10. Frigidaire 25,000 BTU 230V Window-Mounted Heavy-Duty Air Conditioner with Temperature Sensing Remote Control

    The Frigidaire FFRE2533S2 is also a quiet A/C unit. One of the reasons why is its a 220 Volt unit which allows the compressor to run more efficiently.
    220 Volts is not common in every room and are mainly used for a electric dryers and electric water heaters. Running a 220 Volt outlet to a room is not difficult but if this is a problem than it will be better to look at other units that use the standard 115 Volts.

What Size Quiet Window Air Conditioner Will You Need?
Air conditioners are rated by BTU (British Thermal Units) for how much cooling power they have.

The BTU’s a unit puts out 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 it.

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 is also split system type HVAC units which separate the loud parts outside and keep the quiet components inside.

How To Find the Quietest Window A/C Unit
The quietest unit can be found by measuring the Decibels or dB noise levels it makes.

Decibels is 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 between 40-60 dB with the lower numbers much quieter.

When looking for the unit that makes the least amount of noise finding one 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 how a unit wear over time.

Installing a unit that is held in place with brackets and level will not ware out components as fast as a badly installed unit.

Most window air conditioners will be ready to be replaced after 5 years of moderate to heavy use.

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

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

One of things I always recommend is looking at a mini split system since they are very quiet, low-cost to operate, and built to last.

Mini split systems are basically the same as a big home unit only on a smaller scale.

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

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

Of course they do require more skill to setup and require some basic construction skills such as using power tools and wiring.

As always be sure to read the reviews on Amazon or elsewhere to be sure a unit is a good fit for you.

    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.

  2. LivingHigh

    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.

  3. 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.

  4. 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.

    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.

    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. 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.

  7. 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.

  8. 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 ?
