So read on to get chilled without hearing anything to ruin your inner peace.

Quiet Windows air conditioners

On a hot summer day, everything seems too hot to handle. And after making your way through the heat radiating roads you enter your house half baked.

After closing the door, the first thing you do is switch the AC on and let the cool air fill the room with bliss.

Not because of the temperature but because of noise.

Many people complain of having to switch the AC off to listen to someone.

Buyer’s Guide to Quiet Windows AC Units

The main factors that I consider when planning for a purchase are,

  • Cooling Capacity
  • Noise Level
  • Automation
  • Reliability
  • Ease of use

 

Cooling Capacity

The capacity of the Windows AC unit is basically a measure of how easily does it cool a room.

But mind you, a higher capacity unit is not always the better option.

British Thermal Units (BTU) is the measure used to rate the capacity of Windows Air Conditioners. For home use, the capacity usually ranges from 5000 BTU to 12000 BTU.

You need to choose the capacity (BTU) of your AC based primarily on the size of your room.

  • If the BTU is higher than required, the room will be cooled unevenly and you won’t find it comfortable.

  • If the BTU is lower than required, the AC unit will struggle so much to achieve and maintain the temperature that it will make a lot of noise and also get damaged.

 

The table below can help you choose the correct capacity (BTU) for you room size.

Room SIze (Sq. Ft)

BTU

150

5000

250

6000

300

7000

350

8000

400

9000

450

10000

550

12000

700

14000

Apart from room size there are also other factors that may require from you a little bit more cooling capacity.

The secondary factors affecting AC unit capacity (BTU) are:

  • Lack of shading from sunlight
  • Number of people and active appliances like refrigerator, dishwasher, hairdryer etc. that act as heat sources.
  • Frequent opening and closing of the door

 

In order to compensate for the above factors, add a 10% to the BTU for each factor and 600 BTU for each active heating source.

You can now fix the required capacity of your Window Air Conditioning Unit and thereby narrow down your choices.

Noise Level

This being the main reason that you are reading this article, you know how even a good cooling AC unit can ruin your ambience by being noisy.

There are some manufacturers who include the actual noise level of the AC unit in their description.

This is given in Decibels (dBA) and it is usually the amount of noise that the AC produces at its lowest fan setting.

To get an idea of how much decibels is how much noise, check out the table below.

 

Decibels

Example

0

Threshold of human hearing

10

Breathing

20

Quiet Room

30

Whisper, Light Snoring

40

Moderate Snoring

50

Conversation

60

Busy Street, Alarm Clock

70

Hairdryer, Noise Restaurant

80

Loud Radio

90

Bass Drum

100

Subway Train

110

Industrial Noise

120

Jet Plane Take off

130

Gun shot, Rock Concert

Keep in mind that measuring sound level in Decibels is not the same as measuring length or weight.

The Decibel scale is a logarithmic scale. In simple terms, 60dBA is not twice as loud as 30dBA. And 70dBA can be ten times as loud as 60dBA.

So, when one AC units lists 50dBA as its lowest noise level and another AC has 55dBA, don’t think that the second one is just slightly louder than the first one.

It could be way louder than you think.

So it’s better to go for the lowest dBA rated AC available in your shortlisted choices.

Factors such as these can also cause your noise level to increase soon after installing the AC unit:

  • Improper Mounting
  • Faulty parts
  • Dusty environment
  • Over loading due to Lower capacity(BTU)

There are two things to consider when we talk about improper mounting.

One, the AC unit should be mounted in such a way that there is no rattling noise during use.

Two, The mounting should be done in such a way that no gaps are there through which outside noise can enter your room.

This is very critical because, not only noise, but hot air can also enter your room from outside and cause the AC unit to work harder.

Also, keep your room clean and free of dust since, the health of your AC unit is severely affected when dust starts to accumulate over its inner parts.

And as discussed earlier, one of most underestimated cause of noise is having an AC which has a lower capacity than needed for your room.

Automation

By Automation, I mean the features present in most modern AC units like Auto ON/ OFF Timer, Power Saver Mode, Auto Fan Speed Control etc.

You may wonder what does this have anything to do with choosing a “Quiet” Window AC unit. I’ll tell you why.

We all know that an AC (during operation) is most silent when it is running in the lowest fan setting.

So for example, if you have an Auto ON/ OFF Timer and Auto Fan Control, you can set the unit to start cooling the room for sometime before reach home.

Therefore, when you enter the room, the AC has already finished all the hard work and is now just running at the lowest setting possible to maintain the temperature.

You can also set the AC to switch over to a particular temperature or just switch off at a particular time.

Features like these can not only be useful in reducing the noise you experience but can also lower its running costs.

Some manufacturers have special operation modes named like “Power Saver Mode”, “Silent Mode”, “Eco-Mode” etc. 

Reliability

A window AC is a mechanical device with a lot of moving parts and heat exchanging parts.

Therefore it is important that the material used to make these parts are of good quality and are designed well to ensure that the AC runs long without any issues.

But if the parts of the AC are poorly made, although the AC may be quiet and perform well at first, soon after you’ll hear the AC making all sorts of noise while struggling to cool the room.

Investing in an AC only on the basis of numbers in the product description is not a good idea.

If the product is very new, I suggest that you don’t take the risk if the AC is sold by an unknown or relatively new manufacturer.

Instead go for an AC manufacturer whose products are known to be reliable and also  has a commendable after-sales service.

Ease of Use

This is also something that is not directly related to the AC’s noise level.

One of the primary reason that people look for a quiet Air Conditioner is to have peaceful sleep in the night.

When that is the case, you don’t want to wake up in the middle of the night and have to put the lights on, walk to the AC and try to adjust the setting with some confusing knobs or worse-buttons.

The back-lit remote control may solve such a problem.

It is to be noted that if you have a good featured air conditioner you may not need to wake up in the middle if the night at all.

Even little things like the adjustment of vent direction or setting a timer can be really annoying if the AC interface is not user friendly.

So the bottom line is, in order to have a really undisturbed sleep or usage, you need to be able to use the AC unit with ease.

 

Other things to consider

So these are five important factors that you need to consider when planning to buy a Silent Windows Air Conditioner.

Apart from these, aesthetic factors such as, color options texture and design can be left to your own taste.

What is Energy Efficient Ratio?

The Energy Efficiency Ratio is a rating given to indicate.

Also, Energy Efficiency ratio is mandated by the US Government to be displayed in the description on all Windows ACs.

A good Window AC can have an Energy Efficiency ratio ranging from 10 to 12.

Is White Noise produced from ACs good for sleep?

Yes and No. White noise is known to provide a soothing atmosphere for sleeping but not all people experience the same effect. Some may still find it annoying.

Besides, white noise needs to be heard at a low noise level to be of use in sleeping.

And certainly you wont get a proper low volume white noise from a Window AC.

Is a Voltage Stabilizer required for using the AC?

Yes, in most cases, you will need a voltage stabilizer to protect your AC from getting harmed due to fluctuations.

There are some AC models which have voltage stabilization built in, in which case you won’t need to get a separate one.

Conclusion

To conclude, having a quiet windows AC depends half on the manufacturer and half on us who choose and install it.

Following the above guide will help you be wise in choosing the right one for you.

The Frigidaire 5000 BTU is the choice for you only if you are constrained by a tight budget.

If you can spend more, it is better to check the more powerful and feature rich SPT series or the Haier Serenity series.

If you still feel confused, it is better to get in touch with a reliable local AC mechanic who can sort things out for you.

Happy Chilling!
