The Whynter ARC-1230WNH Inverter Dual Hose Portable Air Conditioner and Heater has the highest cooling and heating BTU (14,000 ASHRAE / 12,000 SACC) in the market. The cooling power you need to cool, dehumidify or circulate the air in up to 600 sq. ft of space. Smart functionalities include the NetHome Plus app to control your portable air conditioner through Wi-Fi from virtually anywhere. You can also control it with Amazon Alexa or Google Home voice assistant. Intelligent features such as the 24-hour Timer, Sleep Mode, Auto restart, Self-Diagnosis, Express Run Settings, Schedules, and Filter Check Reminder Light. As pioneers in the air comfort industry, we are introducing the next-generation Inverter Technology currently only being used in high-efficiency ductless mini-split air conditioners to our NEX line of portable air conditioners. The variable-speed system allows the compressor to optimize efficiency and power consumption together while maintaining a specified output. The advantages of inverter technology are estimated 40% – 50% in energy savings, 2 times quicker to achieve desired temperature, quieter operation, minimized temperature fluctuations, no voltage peaks from the compressor. The innovative two-hose-in-one design and the sealed bottom structure ensure no heat leakage. This cooling setup extracts and exhausts air from the outside, so the indoor space reaches an independent and balanced cool air circulation. As a result, the entire room can be cooled down quickly and effectively. The noise level is as low as 47dB(A) in low fan speed, almost as quite as a library. You can control your portable air conditioner anywhere with the NetHome Plus app for Android and iOS and make your home comfortable even before you arrive.

If the included solid window kit slide bar panels do not completely cover your window or door opening, most customers purchase an additional window kit and use both sets. Alternately, a customized longer solid slide bar panel can be made by cutting Plexiglas or PVC plastic to size to be used with the panel with the hose cut outs of the original window kit.

This cools efficiently and is a very quiet unit. However: 1. I had to cut a portion of the window mount for the vent with a saw. My window is your typical window size, so it's really dumb that I had to do that for it to fit. 2. Auto mode isn't very useful because the range is way too big. It will reach above 64 before the AC turns on when you've set it to 60. 3. The app is inconsistent. Sometimes it will only let me set the fan speed by high/medium/low, other times it will let me set a percentage. Also IFTTT percentage would be nice.

When Whynter fixes all the issues, I will give it five stars and buy at least two of them. The positives: 1. The unit is quiet. 2. Cools very well the large room (around 500 sq f). Negatives: 1. I ordered a new item but got an open box item. 2. The box is funny. One side of the box says AC “Cools up to 500 sq. f” while the opposite side says AC “Cools up to 600 sq. f.” 3. Because of the open box, the window panel was broken. I contacted Whynter Support. Right away, they sent me a replacement. Guess what I got? The hose. I contacted them again. They apologized and said I could keep the hose, and they were going to send the window panel again. Guess what I got? The second hose. After that, they asked to send the hoses back. LOL. Finally, I got the window panel. 4. The AC worked perfectly for almost two months. A few days ago, it showed the error EH 06 and did not work. I contacted Support. The part of their response was, “To further assist you, please provide a photo of the unit’s display with the error code on it as well as how the unit was set up. Also, please provide the ambient room temperature.” So, if the Support does not know what this error code exactly means, how to fix it, and can not help me, I decided to return the unit. 5. When I started to move the unit from the room, I got a massive water leak from the bottom (I used this unit only in a cooling mode). Thus, it means there are problems with self-evaporating (or whatever this option calls). 6. The company does not yet start manufacturing and selling extended panels for balcony doors (I checked this info in July 2022). I am a fan of the Whynter ACs. I have 3 of them (different models). I liked the ARC-1230WNH very much, but unfortunately, I had to return it. Please fix all the issues, and I will buy at least two of them as I promised above!

I purchased the model ARC 1230 WNH from Best Buy to cool my small unheated, no air sunroom. We installed it this past weekend and it is doing an excellent job keeping us cool and comfortable and my ceiling fan is helping to circulate the air during these hot summer days. It also has heat, so I am looking forward to seeing how well it performs on cold days and nights. It was easy to set up, and when I had a few questions, Whynter was there to answer them for me. The portable unit also operates quietly. I think this is a good purchase. I am happy with it.
