The Quietest 12000 BTU Air Conditioner

Choosing the quietest air conditioner is one of the biggest steps you can always count on. With the hot season quickly approaching, everyone is looking for a way to beat the blazing heat before utility bills skyrocket.

Conversely, their main focus is to get a few top options that are quiet and reasonably affordable. Luckily, that’s the main aim of this whole article. 

There’re many benefits of air conditioning. First up, they reduce the possibility of asthma attacks while improving your level of comfort. Besides, they prevent electronics from overheating, reduce the risk of dehydration, provide better sleep, and improve work performance.

On average, a great number of people spend a third of their life at home, sleeping. As such, there’s no better reason why you shouldn’t spend this time in comfort. 

Although most households have central air conditioning in their homes, this is not always the most affordable option. We aim to highlight the Quietest 12000 BTU Air Conditioner currently on the market and also help you make the best buying decision. 



Things To Consider When Choosing The Quietest 12000 BTU Air Conditioner

The humming, buzzing, or rattling sound of any air conditioner is not pleasing to most users. ACs installed in offices need to be quiet enough to provide a favorable work atmosphere.

Nonetheless, you’ll love to sleep comfortably in a quiet room, but a loud unit won’t give you peace. However, different ACs incorporate different features that require a closer look.

Let’s now jump into the next part to equip you with the factors to consider before making a purchase. 

Energy Efficiency Ratio

The Energy Efficiency Ratio (EER) is one of the fundamental factors to consider before purchasing your AC. It determines the power consumption of a unit.

It would be best if you chose an AC which is Energy Certified as it will consume less power. Go for an AC with an EER of 13 or more to reduce your power consumption. Otherwise, you’ll spend more on power than other bills. 



BTU is the SI unit used to measure how suitable a unit can convert heat to electrical energy. It stands for British Thermal Units. A higher BTU means an AC can drive out more warm air and bring in cold air faster when looking into an air conditioner.

While buying your AC, ensure you get one that is enough to cool your room. Meaning, don’t go for an oversize or an undersized. An undersized unit won’t cool your room to standard requirement, while an oversized won’t be efficient in terms of Energy. Measure your room size and contact the dealer before making a purchase. 

Furthermore, there are other factors you should also bring into play concerning BTU capacity. If your room is poorly insulated, has a height of 8 ft. and above, or is exposed to sunlight, add 10% to the required BTU. But if it is shaded from the sun, reduce the BTU by 10%. In case you need to cool your kitchen while cooling, add 4,000 BTU to the required BTU. 


Insulation of the unit is also prime as it will reduce the noise. A good AC includes a device that muffles the noise within its system. The muffler serves as a strip of insulation that filters the noise released to the environment. Therefore, look for a unit that incorporates these features to avoid noise disturbance. 



The compressor is the part that ensures the outward movement of warm air and inside movement of cold air. However, it is the part responsible for the noise during air exchange. Therefore, choose an inverter AC that will allow you to adjust the fan speed to a more quiet level. 

Additionally, the inverter air conditioner has an automatic mode that enables the fan to adjust based on the cooling demands.
