Whynter - ARC-1230WN

I have the Whynter ARC-1230WN and I really like it. It was right around $500, which was my max budget, but it’s the best dual hose model that I could find (yes, they are more expensive).  It’d definitely be overkill for your 300 square foot bedroom, but I’ve been happy with the Whynter brand. Mine covers 600 square feet. I have it centrally in my one bedroom apartment and keep the doors open.  My number one non-negotiable feature is a model with auto-evaporation. I had a different model in college that didn’t have this feature, and in Florida (where I went to school), it would FILL the water basin about every three hours, which was so annoying overnight.  When I was shopping this time, I used this [AC comparison spreadsheet](https://www.reddit.com/user/NefariousnessSecret0/comments/1kwgaw6/comparing_air_conditioner_models_portable_window/) to sort the models by auto-evaporation. It used to be pinned at the top of the Air Conditioners subreddit.

I have the Whynter Nex dual hose (12k SACC) in my office and it does a good job. I don't think it will cool an entire 600 square foot area in most climates but it will make a very significant difference. How you set up a portable also matters a lot. A kit like the [breeze stop ](https://breezestopusa.com/?srsltid=AfmBOorU2LjTD5UtbAZoIdxACAHYqk8wZ3CUJQlJsevfpVd5HjFv19Bn) can make a big difference in efficiency. I cut the foam around the oval hose of the Whynter to seal it and stop heat gain through the plastic.

The whynter has a slightly higher CEER compared to the DUO (14.2 vs 13.8) for what it's worth. It does a great job of supplementing AC in my home office without of electronics.

How would you compare the 14S and 1230WN? From what I have seen the 1230WN has a significantly higher cooling rating than 14S and others (Gasbye Inverter 14,000 and Midea Duo Inverter 14,000). The price point is not the greatest but don't want to get a lesser unit to save $100.

Thanks, that's great to hear! I tried another unit but it wasn't the 16,000 it claimed and was shooting out air around 52 degrees even when it's low 80s out. Only downside to the 120WN right now is the shipping time is very wild right now, two weeks to over a month from Amazon.

Looks like no sellers but Amazon and AliExpress right now. I'm going to wait until Prime Day to see if they discount it (looks like earlier this year it was a bit lower). Have a decent one running currently that I'll move to a bedroom when I get this.

I own 2 Whynter units. This will be my 3rd summer with an Arc 14S, and I purchased a 1230WN in April. I've not had to empty either unit in all the time I've had them. It sounds like you may have it set on de-humidify instead of cool. The hoses are so bulky because they are dual hose portable air conditioners. They're better than single hose because they draw air from outside to cool the unit and exhaust it back out instead of pulling from the interior, creating negative pressure and sucking in outside air like single hose units. They're much more efficient, and they do a really good job of cooling 500-600sqft.

We bought the 14K btu Whynter right before the hurricane hit. It is cooling the family room quite well. My window opens side to side so there is a huge gap above the hose outlet. And the unit comes with panels to fill the gap but it is hard to make 3 pieces align and be air tight. It is leaking air pretty bad so I will have to build something a little more leak free after this is over, but we have bee very happy with it.

Yes, is the space insulated? First question to answer. Does it have windows? And which way do they face (aouth, etc)? We have a large 14000btu whynter portable ac in the garage. Its fully insulated and no windows. Works well to keep the space below 80 and around 50% humidity on most days. With that said, If i had the cash and space, a mini Split would be the way to go.

Whether you get a single- or dual-hose model (and dual is much more efficient) add an insulating blanket around the hot exhaust hose to increase efficiency. That made \~2º difference in my situation, and every degree helps! BTW, I've used a single-hose Koldfront for seven years and a dual Whynter for three, and both are still going strong.

The 12K BTU portable units work fine for even a large bedroom. I have three, all Whynter two hose. One even keeps a 600 sf finished attic with seemingly no insulation in the roof at an okay temperature on hot days. When it is over 100F out, it struggles but still the attic is tolerable if not ideal.

Have had 2 Whynter dual hose units over the past 8 years. really solid cooling machines.

I've had a Whynter dual hose AC unit running for a couple years now, works great, cools a lot and pretty affordable

The best one is Whynter and it has two hoses on it if that helps. It's black and is like waist high.

Realize this thread is old. OP, any update here? I'm having the same problem and it's driving me crazy.

I’ve owned multiple portable A/C units and have never had to drain them curious why Whynter is different.

I did this while using the heat mode and it still shut off every hour because the tank was full .

So which hose did you cap the intake or the outflow ?

If you’re going portable, go LG or Whynter. Midea’s hit-or-miss like a Tinder date..looks good online, but disappoints in person.

Any dual hose one will be more efficient and possibly more quiet. I have the Whynter Arc. It does a great job. Some people may find it noisy but it doesn’t bother me. But it IS large so not easy to lug between places.

Whynter. They’re also packed very well in the box.

I owned the Whynter one size smaller for 2 years. I only ran one hose (intake) not two. The dehumidifier works while the ac unit is running. I never had to drain it and the instructions said this unit will evaporate the excess water and it did for me. Most of the time the dehumidifier cooled the room perfectly fine and I also live near the water and it is humid. Maybe it didn't need draining because I only ran one hose, I capped off the other with the cap that came with it and it indicated in the instruction it didn't need 2 hoses. I was pleased overall with the unit. It cooled 700 sq. feet fairly well.

Most are made in the same factory and have different labels slapped on the front, similar to other household appliances. I personally have had good experience with Whynter units. They are known as one of the more reliable brands. As others have mentioned, you should look into dual hose units. They cool the room more efficiently than single hose units by preventing negative air pressure in the room.

Single most important thing: Dual hose units maintain the pressure balance in your room. Single hose units vacuum hot air into your house. Next most important thing. Buy new. These things are consumables. I like my Whynter brand units. They've lasted far longer than I thought they would. I also like my Hisense unit. It is nice and quiet.
