Buying Guide: How To Choose A Quietest Air Conditioner That Is Also Good At Many Other Aspects

Nowadays, with the development of technology, it’s not hard for you to find a quiet air conditioner. In fact, there are thousands of choices for you in the market. I think the right question is: How to buy a quietest air conditioner with many other qualities? Below is our instruction to answer this question. Take a cup of tea and read this, then choose for you an air conditioner that best satisfies you.

Top Things You Should Keep In Mind In Order To Buy A Good Air Conditioner


quietest air conditioner

This is one of the most important things to consider when considering buying an air conditioner, and it might relate to the sound that the conditioner makes too. 

In order not to go too specifically into the technical aspect, I will give you a brief description of what BTU is and How we understand it. BTU (British Thermal Unit) is a measurement of energy. One BTU is the amount of energy that is required to heat one pound of water.

You might feel a bit confused here because air conditioners cool the air, not heat, so I will explain to you how air conditioners work. It removes heat from the air and pushes back cool air. Hence, it could be understood that BTU measure how much heat your air conditioner is able to remove

quietest air conditioner

One thing that many people mistakenly think is that the higher the air conditioning capacity, the more electricity it costs. High capacity does mean high energy consumption, but there are many other factors that determine the amount of energy that an air conditioner uses, I will explain it later.

In such, in order to choose an air conditioner with the most appropriate BTU, you should take into consideration the size of space you want to cool. There are many instructions on the Internet that guide you on which BTU is for which size.

But the thing I want you to keep in mind is that a higher than suitable BTU air conditioner may make your room wet ,because the cooling speed is faster than the moisture removing speed. While an underpowered air conditioner may fail to reduce the room’s temperature to the target, hence it’s likely that you don’t obtain the ideal air quality that you expect.

As I said at the beginning, high capacity might relate to sound creation, as your air conditioner works at high intensity. However, nowadays with modern technology, brands are able to manufacture many types of high capacity product that are completely quiet. This could be a relief for you if you want a powerful machine, though it could be expensive

Factors determine a quietest air conditioner

This is the topic and the main reason why you read this article. There are many factors affecting the noise that an air conditioner creates, I will explain each and instruct you to find quietest air conditioners.

Capacity type

As I said above, capacity may be a problem. It’s not just high capacity air conditioners that could make noise, so do the low capacity ones. If your air conditioner is underpowered, it will have to work continuously in order to bring enough cool air for your room, hence noise is likely to appear.

Instruction: Buy an air conditioner with appropriate capacity (BTU) compared to your room

Type of compressor

The compressor acts as a pump that circulates refrigerant in your air conditioner. It is the part that creates the loudest sound in your device. Nowadays, inverter-type compressors are proven to be quietest. Do consider this information when choosing an air conditioner

quietest air conditioner

Instruction: Buy an air conditioner that features invert compressor

Insulation availability

This feature is especially important for a window air conditioner to reduce noise,as this equipment prevents air from leaking. Therefore, a good and quiet air conditioner should include a strip of insulation.

Instruction: Buy a product that includes an insulation

Multiple fan speed options

Of course fans create noise, we do not have to be very intelligent to understand that. Therefore, an air conditioner with flexible fan speed choices can bring peace to your sleep.

Instruction: Buy a product with plenty of fan modes

Hose system

There are two types of hose system: single and dual. Most portable air conditioners feature a single hose system, which extracts and releases air through the same hose. When single hose system has to work with high intensity, it create noise

The dual hose system does not have this problem because it uses separate hoses.

Instruction: Buy an air conditioner that uses a dual hose system.

quietest air conditioner


You should choose a versatile air conditioner. Many products nowadays integrate air cooling and dehumidifying functions, in order to bring you the most quality air. Do check for this detail when searching an air conditioner

Intelligent control

This is a must for a quality air conditioner. Not only the display needs to be clear and easy to understand, the product’s control must have multiple programs and flexible cooling modes. This is due to the fact that air quality directly affects people’s health, and each person has their own health issue.

Currently, many brands have provided such advanced technology like wi-fi control and voice control. It’s nice that your product has these features, but you should consider the price too.
