With minimal audio output, these quiet units are suitable for noise-sensitive applications. A list of the best quietest portable air conditioners has already been discussed. This buying guide will help the user understand the importance of a few governing parameters.

1. Noise Level

The noise level is the topmost priority for the quietest portable air conditioners. These portable units have components like the compressor, which creates louder noise. Due to the portable design, the compressor is fitted inside the main body, unlike the split ACs installed outdoors. These portable units are thereby modified to keep the noise level low. Several units operate at a noise level below 60 dB, equivalent to the sound of human conversation. Soundproof materials are also used to lower the noise output further.

2. BTU

The overall selling point of a portable conditioner is its cooling power. This power is measured in the British Thermal Unit (BTU) to make the user aware. The BTU rating depends on various parameters like room temperature, size, etc. The portable air conditioners are designed for a BTU rating of  5,000 to 15,000, enough for mid-sized rooms. When the atmospheric temperature is high, and more cooling power is needed, some units offer cooling power beyond 15,000 BTU.

Efficient energy consumption allows better running of the AC units without increasing the energy bills. These portable air conditioners are rated with several certifications to ensure efficient power consumption.

5. Type Of Control

To access the basic functions of a portable air conditioner, various types of controls are offered. The most common control type is the buttons or knobs on the air conditioner’s body. Users have to touch these controls to adjust cooling and other features physically. To add comfort to the users, remote controllers are also offered. Other wireless controls like WiFi and app connectivity are also offered besides the remote controllers. The latest units also support voice control via Siri, Google Assistant, Alexa, etc.
