Guide to choosing the quietest Window AC for your home

Before selecting an air conditioner, there are factors that you should consider. Remember that you are buying the quietest air conditioner, not a typical conditioner.

· Size of your room

The worst thing you could do is to invest in an air conditioner only to discover that it isn’t powerful enough to cool down the room. On the other hand, investing your money on an AC that’s too powerful isn’t a good idea either. A powerful unit can make a small room too hot or cold, and it’ll turn off and on affecting its efficiency and leading to more power consumption. Below is a guide to help you:

2,000 sq. ft. – 29,000 BTUs

1,500 sq. ft. – 24,000 BTUs

1,000 sq. ft. – 18,000 BTUs
550 sq. Ft. – 12,000 BTUs
400 sq. Ft. – 9,000 BTUs

300 sq. ft. – 7,000 BTUs

150 sq. Ft. – 5,000 BTUs

· Noise Ratings

Noise is measured in decibels which indicate how an air conditioner is louder and sound above 140decibels are too loud for our ears and can be harmful. If you’re investing in a quiet air conditioner, first check decibel ratings and not that the lower the decibels rating the quieter the unit.

Here are examples to help you understand these ratings:

  • Vacuum cleaner 70-75Db
  • Busy traffic 70dB
  • A quiet conversation 50Db
  • Normal conversation 60Db

What Is the Quietest Window Air Conditioner

About are some of quiet AC’s you can get today. However, the answer to what is the quietest window air conditioner solely depends on a variety of factors. Different of these AC’s have the distinct decibel ratings and what loud for another person maybe silent for you, and the vice versa is true. From my list, the quietest unit I recommend is the Haier ESAQ406P which has a 43decibel rating, 10 decibels quieter than a quiet conversation and ideal for rooms that require total silence.
