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.

I have whynter portable two duct large size, it's noisy but cools well. I would never buy a single duct portable, they pull their coil cooling air from the room, so every other room gets hot air pulled in. No bueno.

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.

I have a whynter dual hose and it has worked for multiple years. Sort of expensive, but efficient and not very loud.

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.

Had a wynter dual hose on my sunroom last summer (250sqft, all window, no significant insulation) and it handled the space very well. It didn’t have an inverter, was only 12k BTU, so my expectation is the zafro will absolutely crush it. The inverter is also significantly more quiet, so if you use in bedroom, it may be a great option.
