When should you not buy the silent window air conditioner?

When you are looking for the air conditioner, in some cases buying the most silent window air conditioner may not be the best option.

Most air conditioners available in the market labeled to be the quietest are either small power rating of 5,000 to 6,000 BTU. This may not be sufficient to cool down a bigger room or simply not have a sturdy fan to circulate the air.

Don’t forget that the primary purpose of buying an air conditioner is to cool down the room. Having an AC that works without producing much noise is the added benefit.

You may think that higher capacity AC marked with low noise generation may be suitable for your needs, but that may not be the case as the fan may be underpowered. This means the air conditioner creates the cooling, but you may have to leave it on for a longer duration.

How many decibels is a quiet air conditioner

The sound level is measured in decibels. This is the pressure the sound waves generate when it travels through the air. The manufacturers of the air conditioner mention the decibel rating to tell you how loud noise the air conditioner unit makes when in operation.

There are three different types of ratings to measure noise, which range from A-weighted, B-weighted, and C-weighted decibels. The noise generated by air conditioners is low-level background noise and measures at the A-weighted noise scale or dBA.

The other B-level decibel and C-level decibel ratings are used to express medium to higher noise levels.One important thing to know about decibel rating is that it doubles the noise level whenever the score increased by 10 units.

For example, noise at 30 dBA will have double the noise level than at 20 dBA even though the increase is only 10 units. Similarly, a 40 dBA will be double the noise level that is generated at 30 dBA.

Keep this in mind when comparing the noise level of air conditioners. For air conditioners, the rating of 40 dBA to 65dBA or less is comfortably quiet. For comparison, the average noise level in the library is around 40 dBA.

The noise level also drops as you go further from the source. This means if you have a larger room, then you can choose a higher capacity but a bit louder air conditioner without getting bothered by the noise. As you may be sitting farther from the air conditioner unit.

Whereas if you have a small room or installing an air conditioner in the bedroom, then you may have to choose a quieter model of window air conditioner for comfort.

quiet air conditioner

Things to consider when buying the quietest window AC

There are so many different types and capacities of the air conditioner model available in the market. It often becomes confusing and mind-boggling to find the right one as per needs.

But as a starting point, you should consider the following:

Cooling Capacity (BTU) and the room size

The cooling capacity of the air conditioner is measured in British Thermal Units (BTU). This simply tells you how good the air conditioner is in transferring heat. This depends on the temperature inside the room and the size of the room.

Most residential air conditioners range from 5,000 BTU to 21,000 BTU. Anything above or beyond that range has particular use.

The starting point of choosing the air conditioner is to determine the cooling capacity needed based on the room size. Use the following chart to identify the BTU capacity required as per your room size. 

Room Cooling Chart BTU

Use the above chart as a starting point. There is no reason to buy an under-powered or overpowered air conditioner. As it means more noise and wastage of power.

Besides cooling capacity, you should also look out to lower the humidity level inside the room for greater comfort. Fortunately, most AC comes with dual functionality of cooling and reducing humidity.

Contrary, buying an undersized window air conditioner won't be able to cool a room faster. You may have to run it at full fan speed, which means more noise and less cooling.

For a room that faces the sunlight, increase the required BTU power by 10%, whereas for the shaded place, decrease the strength of BTU needed by 10%.

For using an air conditioner in the kitchen, add 4,000 BTU on top of regular room size. So, if your kitchen room is 300 sq ft, then you need 11,000 BTU air conditioner (7,000 BTU capacity for a 300 sq ft room and an additional 4,000 BTU to remove extra heat generated in the kitchen). 

Compressor

The heart of the air conditioner is the compressor that moves the cooling refrigerant through the pipes. It removes the hot air and circulates the colder air to cool the room. The compressor has a motor attached to it that does the heavy lifting in circulating the air.

Air conditioners come in different types and specifications. The silent window air conditioner compressors are inverter type that can be adjusted to operate at variable fan speeds.

It allows greater flexibility and reduces the noise level. You can set the cooling level and air conditioner automatically adjust the compressor speed based on the cooling requirements. 

Room insulation

A well-insulated room prevents the heat from getting inside the room. Most often, the heat transfers inside the room through the circulation of hot air.

If your room is not well insulated and has lots of open spaces, then increase the required BTU by 30%-40%. For a well-insulated or mildly covered room, you can increase the BTU by 10%.

Fan Speeds level

Air conditioners contain a fan that circulates the air to remove the hot air and move in the cold air. Most ACs come with four or five different speed levels. The faster the fan speed, the louder the noise from the air conditioner.

You should pick an air conditioner that has enough capacity to cool the room at the lowest fan speed level. In this way, you will not have to run fans at a higher speed to cool down the place. 

Distance

The farther the air conditioner is from you, the quieter you will perceive it to be. The noise level decreases as the distance increases.

If you have a bedroom near the window, then you want an air conditioner that can cool down the room at the lowest fan speed level. But if you have a bigger place or your bed is farther from the window, then you can choose the higher capacity air conditioner. 

Efficiency and rating

The air conditioners consume lots of electricity and are not cheaper to operate. A high-efficiency air conditioner cools the room without needing much power.

Many manufacturers use Energy Star certification to assure users with energy efficiency. As a general guideline, the smaller air conditioner units are more energy-efficient than large ones.

The energy efficiency rating goes from a maximum of 12 to a minimum of 8. When choosing energy-efficient air conditioner, pick units that are rated above 8. 

Temperature Controls

Window air conditioners come with digital or analog temperature controls. We recommend an air conditioner with digital temperature control as it makes it convenient to operate using a remote. It also gives you greater flexibility in choosing the desired temperature level.

Timer

Timer and programmable start are a nice feature to have in air conditioners. It allows you to set the timer once, and then you don’t have to worry about it.

You can program the air conditioner to turn on before you arrive home, so you don’t have to wait for the room to cool down. 

Energy-saving and sleep mode

The energy-saving and sleep mode lower the cooling when not in use, or temperature has reached the desired level. This saves electricity and is environment-friendly.

Installation Ease

Since you will be installing an air conditioner inside the window, you have to make sure that it can fit properly. You have to measure the dimensions of your window and then estimate the range of air conditioners that come in that size variety.

Most window air conditioners these days are designed to be used in both single and two-fold hung windows. If you are wall mounting the air conditioner, then think beforehand which room you will be installing. Make sure there is enough open space to wall mount the air conditioner. 

Fan only mode

The fan only mode option allows you to use the AC without engaging the compressor. This is ideal when the temperature is not too hot, but you need some air circulation inside the room.


The fan only mode option in AC saves space and money as you don't have to buy a spare fan. 

Remote control

The remote control is convenient to change the temperature or turn on and off the air conditioner unit without getting out of bed or couch. Depending on the price range of the air conditioner, some remote may have more functionality than others.

Choose the one which includes the features you will be using most such as temperature settings and fan speed.

How to keep air conditioner quiet

There are some steps you can take to keep the air conditioner remains quiet when operating.

Keep it away from sunlight

If it’s possible, install the air conditioner on the side where it does not get exposed to direct sunlight. The sun warms the air conditioner, then it has to work harder to keep the cold air circulating inside the home.

If you have a limited option to install the window air conditioner, then you can install an awning to keep it covered and prevents the exposure of direct sunlight. 

Close the curtains

Using dark curtains on the windows prevents the sunlight from getting inside the room. Keep the windows closed during the hot weather as it stops the warm air from getting inside the room.

Clean air filter regularly

The filters in the air conditioner prevent the dust or other harmful air particles from getting inside the home. Keeping it clean at least once a week keeps it free from dirt and debris and improves the air circulation.

This reduces the required power level needed to cool the room and saves on electricity and reduces the noise level. 

Maintain compressor and cooling coil

Proper maintenance of compressor and cooling coil improves the life of the air conditioner. By cleaning any dirt or debris buildup on the compressor will enhance the efficiency of the compressor.

The cleaning of the cooling coil allows the better transfer of cold temperatures to the passing air from the fan. 

Tighten moving parts

Air conditioners have lots of moving parts. A loose part or screw can create a constant nagging rattling noise that may become uncomfortable and annoying.

By annually checking any loose nuts or screws prevents the accidental damage to the unit and also reduces any ratting noise from the air conditioner. 

How to reduce electricity consumption when using AC

Several different factors may determine the amount of energy the air conditioner may consume. The first is the overall energy star rating that tells you the energy efficiency of the air conditioner.

Buying a higher energy efficiency rating appliance may help reduce the operating cost of using the air conditioner.

The size of the room is another factor that determines the energy needed to cool the room. The bigger or hotter the area means more energy required to cool it down.

Using the right cooling capacity of the air conditioner is essential to maintain optimal cooling efficiency and reasonable energy use.

The third way to lower the energy cost of the air conditioner is only to turn on when needed. There is no reason to keep the air conditioner unit on when no one is inside the room, or you don’t have any other valid reason to keep room cooler.

You may also consider installing an air conditioner in the room where you spend most of your time.

How can you make window air conditioner quieter

Regardless of which type of quietest window air conditioner you purchase, it starts making some noise as it gets old. In older AC units, you may hear various kinds of sounds. By identifying the source of noise, you can fix the problem rather than replacing the full unit.

So, if you are wondering why is your window air conditioner making a loud humming noise? Here are some everyday noises you may hear from your AC unit and ways to fix it.

Clanking

The clanking noise is produced when the compressor does not function properly, or the AC fan blades rub against the metal piece.

You can look closely inside the air conditioner and check if anything is obstructing the fan motion. Also, pay close attention to the compressor to identify the source of the noise.

It will be unlikely that you may be able to troubleshoot the compressor without having any required skill. But sometimes dust and debris on the compressor may cause it to overheat and produce noise. Remove any obstruction and clean the compressor, and then check if the sound still persists. 

Clicking

The clicking noise usually comes from the mechanical thermostat that may have malfunctioned and made a clicking noise.

The mechanical switch in the thermostat moves up and down to make contact with the electric circuit. You should not attempt to fix it while the air conditioner plugged into the electrical outlet. 

Humming Noise

The humming noise is usually generated when the compressor does not get enough power supply to turn on. This may be a result of a faulty electrical connection or low power level in the house.

You should not attempt to operate the air conditioner as it may cause permanent damage to the motor inside the compressor. It them may become costly to repair. 

Banging

This happens when either the fan is not balanced correctly or something making contact with the compressor when in operation.

Most often, you can visually check if there is no obstruction to the fan or any kind of damage or bending to the blades. Get the unit checked by a professional mechanic to prevent any further damage before continuing to use the air conditioner. 

Squeaking

The squeaking noise comes when the fan support wheels get dry and may need little lubrication. You can buy motor oil and use a couple of drops at the moving parts to lubricate it.

It usually removes the dirt and debris to keep it moving freely and reduce or eliminate the squeaking noise.
