This air conditioner has a whisper mode that keeps the noise to a minimum. This mode allows the device to maintain the desired temperature in a non-aggressive way, by not engaging the maximum level of the fans. This feature makes this AC a perfect choice for bedrooms.
This AC comes with a neat remote control. It has a display that shows the status of the device, and when not needed it can be stored in a special compartment on top of the air conditioner.
A great feature of this portable AC is the Real Feel setting, which helps to balance out the ideal humidity level with your set temperature. This creates a better atmosphere in the room and helps create comfortable conditions throughout the day, responding to humidity level changes.
While the installation process is usually pretty straightforward, you can come across problems if you need to install the unit in a horizontal window, since it will require additional materials and tools.
Despite its powerful performance, this air conditioner still manages to operate quietly, emitting just 53 dB of noise, which is low enough to use in a bedroom, while people are sleeping.
The oscillating louvers of this AC force the air to circulate, allowing to cool the room evenly. This improved circulation also contributes to a quicker cooling process.
Due to its round and delicate shapes, this air conditioner looks premium and futuristic. The controls and display are very well integrated and even the remote control is a design piece on its own, with a minimalist, round shape.
A standout feature of this unit is its ability to connect to a Wi-Fi network. This allows controlling the air conditioner using a smartphone or a virtual assistant, like Google Assistant or Amazon's Alexa. With this, you can remotely change the settings and check the current status of the device, as well as set schedules.
When it comes to cooling performance, this unit easily competes with other premium portable AC units. It has a cooling power of 12,000 BTU and can cool down places as large as 550 sq. ft.
The ARC-122DHP is one of the quietest portable AC units available - it does not exceed 52 dB, approximately the level of a calm conversation at home. The loudest part is when the compressor cycles on and off, but it is mostly not audible over the fan. However, if installed in the bedroom, it can still wake you up if you're a light sleeper.
This unit self-evaporates most condensate under average conditions, but if it's really humid, an automatic internal condenser pump for continuous drainage kicks in. You can connect the drain tube to the exhaust tube and direct the water outside, or just put a bucket beside the unit and let the water drain there. This way the water tank never gets full, which means that the compressor won't shut off on its own.
The Whynter ARC-122DHP is efficient in spaces of up to 400 square feet - it offers 12 000 BTU cooling and 10 000 BTU heating output. The angle of the deflector on this unit is adjusted so that the air shoots forward, going up at about 40 degree angle - this way the cool/warm air gets spread evenly around the room.
When in AC mode, the fan is on continuously, there is no way to set it to turn off automatically after a while. The condenser cycles on and off, but the fan doesn't, and it can emit a high-frequency sound when set on medium or high speed.
The window kit comes in two lengths - 26''-28'' and 36''-38''. It rarely fits the window perfectly, most people need to cut the plank and add air conditioner foam weather stripping, used for window units. The instruction manual doesn't help much, because it's poorly written (lacks some information on how to connect the hose and how to detach connector from the window kit).
