How to choose a quietest window air conditioner   

For selecting the quiet window air conditioner, it is important to factor in all the various components that determine how much noise can be dampened and controlled. The most common way in which air conditioners reduce the overall noise level and keep the noise to the lowest and sometimes nonexistent is by using quieter compressors and extra insulation pads.

  1. Noise Level: An air conditioner has to be under 55 dB to be considered as a quiet window air conditioner. DB or Decibels is the measurement unit of the loudness of sound present in the air that can be perceived by the human ear. Choosing a lower dB level air conditioner is important as even a minor increase in dB level can produce a noticeable difference in sound. For example, any sound at 70 dB unit is double than the same sound at 60 dB unit, the difference is only 10 dB, but it results in a louder sound.
  2. BTU Unit: BTU stands for British Thermal Units; it signifies the amount of heat the unit can remove from the air per hour. The BTU is calculated by BTU/ per hour. Unlike dB, an air conditioner with a higher BTU unit is considered a better air conditioner. A great tip for buying a window air conditioner is to buy a higher BTU power air conditioner than the one you require.
  3. Room Size: The size of the room plays the most significant part in deciding the right unit of air conditioner needed for a noise-free cooling. Every range of BTU unit has a maximum cooling capacity. Thus, you must select the right BTU unit for your window air conditioner. For better understanding here’s a chart with BTU units and their maximum cooling area:
  • 5000   BTU: 150 sq. ft.
  • 6000   BTU: 200 sq. ft.
  • 8000   BTU: 300 sq. ft.
  • 10000 BTU: 350 sq. ft.
  • 12000 BTU: 400 sq. ft.
  • 18000 BTU: 600 sq. ft.
  • 25000 BTU: 900 sq. ft.
  1. Room Type: Choosing how many BTU units you need also depends on the type of room. For example, kitchens and bedrooms need higher BTU units than a living room or study.  Another factor in this is the number of room occupants. The ideal BTU unit chart is usually made for two people, and therefore, for every additional person in the room, you need to add 500-600 BTU unit for efficient cooling.
  2. Energy Efficiency Ratio: One important factor to consider when buying a window air conditioner is the Energy Efficiency Ratio. It is the ratio of output cooling energy to input electric energy at a given output point. A good EER rating is 12 or above, and however, when comparing two different devices, a higher EER rating is considered the best.
  3. CFM Power: CFM means the cubic feet per minute; it is a measurement unit used to determine the velocity of airflow into or out of space. Higher CFM in air conditioner means a higher range of airflow and higher cooling.
  4. Multi-Functionality: Modern window air conditioners are designed to serve multiple functionalities. As opposed to traditional window air conditioners that only served in the summers for cooling purposes, modern window air conditioners can be used throughout the year in all weather conditions. Along with using the air conditioner to fight the summer heat and cool your house, you can use your air conditioner to dehumidify and heat the room as per your comfort. Additionally, you can use the air conditioner as an air filter as they come equipped with anti-microbial air filters to ensure clean and fresh air in your home.
  5. Extra features: Well, features are the selling point of any product, in addition to noise reduction, you would also need an air conditioner that is easy to operate and offers a lot of features.

After thorough consideration, we have prepared a list of window air conditioners that operate at a low noise level.
