Best Portable Air Conditioner TechnoBuffalo 2021

A portable air conditioner is an efficient and effective way to cool down your home, or an individual room, on hot summer days (or even year-round in some places). You can place the unit and direct the airflow to exactly where you need it, and most air conditioners are quiet enough to hold a conversation while it is running.

Bottom line

Before choosing a portable air conditioner, get an idea of how big the room is where the unit will be placed. The average size of a living room is 216 square feet while a bedroom is about 132 square feet and a kitchen between 240 and 360 square feet. Knowing this will eliminate several air conditioning models based on their inability to cool your home.

The Whynter ARC-14S is one of the best and most flexible option because it is efficient enough to cool down most areas, including a studio apartment. It works in both humid and arid environments and will recycle moisture pulled from the air to help cool the air circulating through it. This means there isn't a collection bucket that needs to be emptied. You can set the thermostat down to 61 degrees Fahrenheit, but this unit can also be used as a heater. Settings can be controlled from the digital panel on the air conditioner or with the included remote control. The Whynter air conditioner is pretty big, weighing 80 pounds, and has a high price tag. But the amount of flexibility and the efficiency of its cooling, and heating, capabilities are worth the cost.

The Black & Decker BPACT10WT is also a good choice for a portable air conditioner. The Black & Decker works similarly to the Whynter, but chills a smaller area - 250 square feet compared to 500 square feet. Black & Decker, too, is bucketless, but allows collected moisture to evaporate rather than recycling it.
