Whynter - NEX ARC-1030WN Portable Air Conditioner

Get a dual hose. Home Depot had a nice Whynter one on sale, for like $389 which is a dual hose which means it takes air from outside and not inside and is far far more efficient. So far, so good. It blows so cold I had to cover up.

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.

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.

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.
