Whynter - ARC-14SH

You can put the vents on horizontal sliding windows as well. As others have mentioned, most of the time you can extend the plastic window kit to cover the entire area. If not, you can order an extension or an extra window kit from most companies who sell portable air conditioners. If you're willing to put in a little extra money too, you can get a portable air conditioner that also has a built-in heat pump that can provide extra heat in the winter as well. This is what I use in my home to heat and cool the upstairs. I have a heat pump downstairs and a portable AC with a built-in heat pump upstairs. It works great! This is the one that I use: https://a.co/d/5bxFrrp You can order an extra window kit to extend the one that comes with the portable air conditioner even further to cover a larger window: https://www.homedepot.com/p/Whynter-Dual-Hose-Window-Kit-for-ARC-110WD-ARC-122DS-ARC-122DHP-ARC-12SD-ARC-12SDH-ARC-131GD-ARC-14S-ARC-14SH-ARC-143MX-ARC-WK-DUALN/334467729

Recently had success in my attic with the “Whynter Portable Air Conditioner 14,000 BTU & Heater with Dual Hose”. It cools about 500 sqft no prob

Second all this, don't get a single hose unit because it starts to pull in air from the rest of the house (instead of from the outside like dual hose units) so it's less efficient. Also for portable AC you need a higher BTU rating compared to window units. Currently I am using the dual hose Whynter ARC-14S 14000 BTU for an average sized bedroom and it works well. It is really loud compared to most other portable ACs though (if that matters to you). Previously I've used other models like a single hose Sharp 11500 BTU unit, and single hose SPT 12000 BTU unit that were much weaker. If you can find anyway to use the window unit (use a plastic panel, a wood panel, anything) you should definitely use it, it's a much better value than any portable unit. Just make sure that your HOA allows it, in all the neighborhoods I've lived in window units are always banned because of aesthetics.

Or a dual hose, i recently bought a whynter 14000btu and it will cool most of the top floor of our house. With single hoses pumping out air inside the home it builds negative pressure so everytime you open a door to the outside it will suck in all the outdoor air (also leaks in through other spots in the house)

Yes, is the space insulated? First question to answer. Does it have windows? And which way do they face (aouth, etc)? We have a large 14000btu whynter portable ac in the garage. Its fully insulated and no windows. Works well to keep the space below 80 and around 50% humidity on most days. With that said, If i had the cash and space, a mini Split would be the way to go.

Hi, currently living in my 06 Sienna. If you are set on a portable: A) Get a Dual Hose. The intake being outside the vehicle mitigates a big part of the vaccuum effect which draws heat in through the gaps and seals. B) Insulate the Hoses: Wrap hoses with a single or a comination of insulating material(s) C) Insulate your Windows: Use insulating foam boards to make window covers for your rear windows and windshield. This can shave hella degrees on a hot day. D) Get enough BTU: Ignore the sq ft recommendations, you are cooling a mobile oven. I am running a Whynter 14k BTU Dual Hose (there are cheaper and honestly probably better comparable units), and it makes the space livable with no insulation on the hoses, and shitty thin window covers, in direct sunlight E) Get enough Wattage: The unit I bought said around 1300 continuous watts. Bullshit. This thing regularly pulls 1800 for lengths of time. Thats alot. I have a Bluetti AC200l + b300kx2 totaling 7600 watt hours roughly, so I can it run it for a little over 4 hours on a full charge. I run 3x 200w Renogy panels on the roof, so 600watts per hour, and will be investing in a Charger1 (DC to DC smart charger [wont draw from a battery with too love of voltage]) to add another roughly 500w per hour roughly while driving...It's not enough, and it still won't be enough. Power storage for HVAC is tough, so have enough battery, and always be charging.

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.
