Whynter - ARC-131GD

I bought myself a StandAlone Ac unit from homedepot. It has casters on the bottom and handle indentation on the side. I rolling in and out the house as needed. They're around $480 but you can finding cheaper online. I have a WHYNTER ARC -131GD portable dual hose ac. It works Phenomenally

How is the ARC-14S so far? It's been about a month (maybe longer) based on this Reddit post. I have a Whynter ARC-131GD but it doesn't cool this space enough. (Sun exposed roof for second floor bedroom with a sun-exposed storage area). It's a pain to find information about hose extension, even Whynter doesn't mention it on every product they sell.

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.

If you have the money, buy a dual hose Whynter portable AC. Otherwise - the design and construction of single hose units is such that you won’t be able to get it to not pull vacuum, even by adding a second hose to provide it with outside air. There will be leakage inside the unit itself that will prevent you from getting a perfect loop from outside to outside. But that’s still going to be much more effective than running it with the stock single hose, so it’s worth doing, and will be your best short term solution if money is tight.

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.

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.
