A large percentage of US homes have air conditioners to keep their homes fresh. Despite a number of the households having cooling systems that are set outside the house, some use room AC’S like the window air conditioner units.

Most window air conditioner units produce minimal noise compared to the usual portable air conditioners.

As much as a number of individuals don’t mind the minimal noise that is produced by these air conditioners, there is another bunch of people who prefer the silent type. Well if it’s your first time purchasing this type of air conditioner you may find trouble in finding the brand that will suit you best. Below is a guide meant to help you make an informed decision when it comes to getting a quiet window air conditioner for your home cooling needs.

Before highlighting the particular brands of quiet window air conditioners to go for, let’s have a quick look on the aspects that will help you determine the one that will suit you best.

Decibel Levels

The decibel scale of a window air conditioner is an important factor to consider while choosing one. This is because it is used to determine the density of sound waves going through the air from the noise source. In other words, the decibel level of the window air conditioner will help you measure the sound intensity to expect from the equipment.

Normally, decibel levels go up in powers of 10. For instance, a window air conditioner with 50dBA is expected to be way louder compared to the one with 40DBA. Also important to note is that the intensity of decibel level continues to increase as we move up the ladder. Take an example of a 60bBA unit and a 70dBA. You will definitely expect that the noise level difference between the two will be reasonably minimal, but on the contrary, the 70dBA unit is twice as loud as the 60dBA unit. Basically, you need to have in mind that you have to take note of the decibel rating of the AC you intended to buy because it will profoundly determine the noise levels in your home. Choosing a unit with a low decibel rating will help reduce the white noise produced by the unit.

Another aspect associated with the decibel level is distance. The overall sound intensity of the unit is not only determined by the decibel rating of the unit but also the distance between you and the unit. If you intend to place the window air conditioner far from the room you intend to cool, you can enjoy some flexibility while choosing the decibel level of the machine.

Energy Efficiency

The ability of a window conditioner unit to save energy is an important factor to consider when getting one for your home cooling needs. This is because it determines how much you will be spending on the unit at the end of the day. The energy efficiency ratio is used as a top measure in determining the unit’s energy consumption level. Most of the window air conditioning units sold in Amazon have the energy efficiency ratio certification. In most instances, the ratio ranges from a maximum of 12.0 and a minimum of 8.0. Any unit with an energy efficiency ratio of below 8.0 is not recommended.

BTU Capacity

The performance of the unit is highly determined by its BTU (British Thermal Units) capacity. The BTU basically measures the efficiency of unit in changing warm air into cod air. Establishing the BTU capacity of the unit will enable you to determine the size of the room where it will come best.

An important point to note is that getting a unit with a BTU capacity that’s extreme on both sides will leave your cooling needs unmet. If you get a window air conditioner whose BTU capacity is low, it won’t be able to supply cold air in the room as required. On the other side, if the BTU capacity is too high, it results in a rampant temperature drop that not only leaves the room cold but also sweaty. Just in case you have no idea of how BTU capacity goes with room size I will highlight a number of room sizes together with the appropriate BTA measurements required.

Room Size

  1. 150
  2. 250
  3. 300
  4. 350
  5. 400
  6. 450
  7. 550
  8. 700

BTU Capacity

  1. 5000
  2. 6000
  3. 7000
  4. 8000
  5. 9000
  6. 10000
  7. 12000
  8. 14000

The above-listed measurements will work well for you, but you may need to make some slight changes to the BTU capacity in the occasion of the situations mentioned below;

  • When the room is blocked from sunlight reduce the BTU by 10%.
  • In case there are plenty of people in the room add 600 BTU for each.
  • If the unit is for the purpose of cooling the kitchen while cooking you can add 4000BTU.
  • If the conditions below are in your room, you will need to add the BTU by 10%
  • Is exposed to much sunlight
  • If the ceiling is highly placed
  • When the room has poor insulation


It would be pretty disappointing to take home a window air conditioner that doesn’t fit your window. For that reason, it is quite important to ensure that you purchase the unit that’s a perfect fit for your window. Out there in the air conditioner market, you will find that a majority of them are designed to suit both single and twofold hung windows. However, if your windows are the casement or sliding type, you will still find a design that will suit them perfectly. Note that ensuring that the model is right for your window is not just enough, you will also need to check the dimensions too to ensure that they will fit your window.

In case you are looking for an air conditioner that can be installed through the wall, this type can work out for you regardless of it being a window air conditioner. However, you will first need to check the user’s manual to ensure that it’s fit for wall installation. Doing the wall installation without a previous experience may be quite a hassle, so it’s recommended that you get a professional to do the job.


Getting value for money is one aspect that every customer looks at while purchasing their products. Well, how about getting yourself a high-performance window air moisturizer with minimal noise levels at the same time? This can be quite a great deal. With that it is important not to forget to look at the quality of the unit while in pursuit of the one with minimal noise production. A quality air conditioning unit will enable you to enjoy longevity as well as value for your money.

Noise Level

The noise level of an air conditioner is normally a primary factor that many people look at when it comes to buying an air conditioner. This is because having a noisy air conditioner in your house is definitely going to interfere with the serenity of your home. Though most manufacturers have not been able to design air conditioners that are noiseless they have come up with models with quite a minimal operational noise.

Some of the features that are always part and parcel of the modern air conditioners include;

  • Auto cooling Mode
  • These units are always operation when the room needs some cooling effect. This, in turn, helps in cutting down on electricity costs.

How do I get the Best Quiet Cooling Experience?

Well, purchasing just the perfect window air conditioner for a quiet cooling experience may prove of no use if the unit is not handled correctly. As you generally sleep much better in a cooled environment. To avoid such occurrences, let us have a look on some of the factors that you should have in mind while putting the unit into use.

Place it in a sheltered area

As we all know, air conditioners are likely to perform less when exposed to full sunlight. For that matter, it’s always a good idea to place the unit at the shaded area of the window. In an instance where the window lacks a shaded area, you can always use an awning to provide shelter for the equipment.

Clean the Filter

Keeping the filter clean is an important aspect of ensuring that you get top notch fresh air from your air conditioner. Always make sure that you clean the filter regularly. If your equipment is the modern type, you won’t have any trouble keeping track of any dirt on the filter since it will always give you an alert anytime it needs cleaning.

Examine the Power Cord

Sometimes the annoying vibrating noises coming from your Window AC unit could be as a result of some faulty power cord connection. This is because the moment the power cord is malfunctioning the unit will definitely lack enough power supply.

With that in mind, it’s vital always to check the power cord to ensure that it is not twisted or worn out. You can always replace the cord yourself or find some help from a professional if you feel incapable of doing the replacement.

Check out the Insulation

All the window air conditioner units come with insulation meant to reduce the noise that is produced when the unit is in operation. When the insulation is not in place you may notice the presence of some unusual noise when the unit is in action. If you discover that the insulation is missing or maybe it is worn out you are definitely going to need a replacement.

If replacing the insulation sounds quite tactical to you, getting a professional for the same would be a good idea. Note that the replacement must be done with a moisture resisting material.

Proper Installation

To avoid any rattling from the equipment, proper installation is needed. If you are installing the unit on your window ensure that it is fixed tightly on the window frame. For tightening purposes, you can always add caulk or putty to the edges. Ensuring that the window frames are firm is also vital to avoid mounting the unit on a droopy window frame.

On installation, it’s also important to get a professional to do it if you feel unsure of being able to do it correctly using the user’s manual.
