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.

I believe the brand is Whynter. And it's a fuckin good portable AC.

You’re not doing anything wrong..portable ACs are mold traps by design. Sitting all winter with leftover moisture = fungus party. Run it on fan mode before storage to dry it out. As for brands, try Whynter or Midea dual-hose. They’re slightly easier to clean. Or go mini split and never look back.

Should work fine. You’ll have to figure out something to do with the condensate water. I had a Wynter unit for several years, heating and cooling an area much too large for it in SoCa. Because it was undersized it did’t always do a great job keeping up and it ran constantly, but it kept working. The one time I had an issue the customer support from Wynter was outstanding and I was able to get it going again right away. I don’t see Wynter mentioned these days. I hope they still make them. Mine was solid.

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 did the same thing with mine. The whynter lasted 12 years using it every night. I plumbed mine through the wall as well.
