Whynter - ARC-1050XP

Look. I’ve used so many of these bad boys over the years, and most of them are terrible. My windows can’t accommodate a traditional window unit, so portable is my only option. I’ve hated almost all of my portable units for various reasons, and either returned them or sold on FB marketplace. By FAR my favorite is the Whynter ARC-1050XP which I picked up at Home Depot. I like it even better than the dual hose model I had prior. It’s quiet enough, the compressor doesn’t rattle or thud, and it cools well. I am so happy I found this model because it’s leagues better than any other I’ve tried.

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.
