"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."
"The hoses are so bulky because they are dual hose portable air conditioners. They're better than single hose because they draw air from outside to cool the unit and exhaust it back out instead of pulling from the interior, creating negative pressure and sucking in outside air like single hose units."
"it’s the best dual hose model that I could find ... And yes, it *is* a dual-hose model, which makes a big difference in efficiency and keeping the room cool without creating a vacuum."

"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"
"It works really well, I can keep my shop at 70 degrees when I'm working."
"Recently had success in my attic with the ‘Whynter Portable Air Conditioner 14,000 BTU & Heater with Dual Hose’."

"The fan that circulates the air is so ridiculous it sounds like an airplane is idling inside my house, and it literally changes the air pressure in my kitchen and hurts my ears"
"The biggest issue is the noise it makes, I move a lot from side to back and vice versa during the night. The noise sounds like balloons rubbing against each other. I've tried wrapping it in a blanket, which helps a bit but still makes a lot of noice."
"Loud as hell. ... Ditto works really well, but loud as hell."

"The unit I bought said around 1300 continuous watts. Bullshit. This thing regularly pulls 1800 for lengths of time."
"Also for the price you can get 2 small window units that will run just as good, if not better and will be cheaper on the electricity bill"

"the splash motor wasn't connected at the factory. Opened it up, attached the connectors and it hasn't needed to be drained once even in South FL summer."
"I did this while using the heat mode and it still shut off every hour because the tank was full ."
"I’ve owned multiple portable A/C units and have never had to drain them curious why Whynter is different."

"When it is over 100F out, it struggles but still the attic is tolerable if not ideal."
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.
r/askportland • What portable AC unit brands or models do you recommend? ->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
r/AirConditioners • Has anyone tried this AC from Costco ->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.
r/AirConditioners • Portable AC units that don't mold or are easy to clean? ->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.
r/AskEngineers • HVAC - Can i create positive pressure in an apartment with a portable air conditioner? ->Realize this thread is old. OP, any update here? I'm having the same problem and it's driving me crazy.
r/AirConditioners • Whynter portable air conditioner - why? ->I’ve owned multiple portable A/C units and have never had to drain them curious why Whynter is different.
r/AirConditioners • Whynter portable air conditioner - why? ->I did this while using the heat mode and it still shut off every hour because the tank was full .
r/AirConditioners • Whynter portable air conditioner - why? ->So which hose did you cap the intake or the outflow ?
r/AirConditioners • Whynter portable air conditioner - why? ->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.
r/AirConditioners • What is the best brand for portable ac ->Whynter ARC-1230 or ARC-14S Dual hose and 14,000 glorious BTUs. Not cheap but they're the best of the best.
r/Apartmentliving • Cooling suggestions for apartment with no AC and no window unit? ->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)
r/Appliances • Installed an air conditioner, what did I do wrong? ->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.
