How To Choose The Most Powerful Portable Air Conditioner?
Room Size
To choose the most powerful portable air conditioner, considering the room size that you intend to use it is a must. The larger the room area, the more power it will need to cool down.
Portable air conditioners are categorized by the heat quantity they can dissipate in British Thermal Units (BTU), the power input in kilowatts (kW), or both.
Our experts find that the general amount of power needed for most portable ACs is somewhere between 2900kW and 5200kW. Meanwhile, according to Canstar Blue:
- 215 square feet can be cooled by a 2800kW system
- 325 square feet by a 4200kW system
- 430 square feet by a 5600kW system
Maneuverability
Unlike central air conditioners, the portable models can’t be used for the entire house or apartment but just a certain space. But it can be moved from room to room.
Therefore, considering a unit with rolling wheels is quite practical.
It would be better if the portable air conditioner is lightweight and compact in size as well.
Noise Level
If your new portable air conditioner is used for a bedroom, kid room, or home office room, it should be as quiet as possible. Noise level is another important feature to keep in mind, from that point!
With portable air conditions, noise is commonly released from the fan during operation.
The higher the speed mode, the louder. Therefore, it is good to choose a model with multiple fan speeds for different uses. The ideal noise range of a portable AC for a bedroom should be under 55 decibels.
Besides, a Sleep Mode would come in handy for quieter operation.
