An air conditioner can be incredibly expensive, bulky, and noisy. However, a portable air conditioner is an energy-efficient and ultra-quiet cooling solution for your home.
The best thing about a portable air conditioner is that it can be wheeled from room to room, wherever you need optimal cooling results for the summer months. So instead of spending your hard-earned dollars on an expensive air conditioning unit that is permanently fixed to a window, an affordable portable air conditioner reduces energy consumption by cooling one room at a time.
How to Choose the Quietest Portable Air Conditioner
Portable Air Conditioner Plus Dehumidifier
Portable air conditioners come in 2 types: a basic unit that provides cool air and an air conditioner that also works as a dehumidifier. Most portable air conditioners have a dehumidifier mode, which is a great function for extra humid summers. The dehumidifier reduces the humidity in the room so you can relax in a refreshingly ultra-cool and comfortable environment.
Quiet Operation
The sound output level of a portable air conditioner is indicated by decibels (dBA). Most portable air conditioners operate at 52, 53, or 55 dBA. These levels are considered to be very quiet operating levels for an air conditioner. The quietness level can also be determined by the room size and the air conditioner’s cooling output.
Room Size
Portable air conditioners are designed to cool different room sizes. Small rooms from 225-350-feet, medium-sized rooms from 350-450 or 550-feet, or larger rooms up to 600, 700, or 1,000-feet.
The overall level of cooling and the unit’s quietness level can also be affected by the set-up of a room. So think about where you want to use the air conditioner. Does the room have an open-plan design with no doors or does the room have a very high 9-feet ceiling?
Cooling Output
An air conditioner’s level of air cooling output is measured by BTU which stands for British Thermal Unit. This unit rating is used to measure the air conditioner’s thermal (heat) energy. Portable air conditioners generally range from 6,800-14,000 BTU. A 6,800-8,000 unit will be very quiet but a 10,000 plus model can be a little loud in a very small room.
Single Hose or Dual Exhaust Hose Portable Air Conditioner
A single exhaust hose is ideal for smaller rooms. However, for a larger room, a dual air conditioner delivers a faster cooling rate but it may be noisier than a single exhaust hose model.
Easy Portable Air Conditioner Installation
A window kit is a great solution for a quick and easy setup. Once you have unpacked the manufacturer’s window kit, install the exhaust hose or hoses to your window as per the instructions. Plugin the air conditioner and sit back and enjoy the cool air.
Quietest Portable Air Conditioner Additional Features

- Three fan speeds: low, medium, and high
- An adjustable thermostat in Fahrenheit or Fahrenheit and Celcius
