Whynter ARC-143MX 14,000 BTU (9,456.1 BTU SACC) Dual Hose Cooling Portable Air Conditioner, Dehumidifier, and Fan with 3M Filter Storage Bag, up to 500 sq ft in Platinum/Black

Bought this because I needed another unit, and since I already have a Whynter unit like this, I knew how good they are. And this one is no different......works great, cools fast, and not very loud. Installation was easy and straight forward. The dual hose design makes it very efficient.

I bought the first one in 2017 and the second one 2018 and both work flawlessly. Here is the only way to operate it which will cause the least wear.1) turn power on. (left button as you face it)2) press the '3 function button' to the 'compressor' symbolized by the gear. (next to the power button)3) press the temperature button down to 60 degrees4) let it run continuously all day ( this is much better than cycling on and off)5) when you are ready to turn off the a/c cooling, press the '3 function button' two times (leaves the gear symbol, passes over the dehumidifier setting, [water drops symbol] and land on the fan setting, [fan blade symbol](do not press the power button 'first') The fan only function will cool the compessor and evaporate water condensation throughout the system6) after 5-10 minute press the power button to off.7) when you start it up, press the power button (the function button will still be on fan )8) press the function button once and the selector will leave the fan setting and go up to the gear/compressor9) at the end of this shift repeat the above. press the function button 2 times to fan, let it run 5-10 min then presspower button.Position the unit in a strategic place in the right size roombuy a/c hose wrap and wrap the exhaust hose as it get hotMy unit is in a slightly larger roam than suggested but I am able to shut doors and limit the cold leaking.My second unit is in my bedroom and easily cools that 1500 sf roomI did not like the compressor going on and off knowing its harder on the compressor,If you press the function button where the compressor goes on then off, it will take 3-5 minutes for the compressor to come back on even though the settings are correct. Safety feature.I ordered an extra set of hoses and 3d printed couplers in order to get the unit to sit in my corner. Used the hose insulation for arrest the radiating heat from the long hose. I also made a custom window panel that I doweled into the sill and the lower edge of the window frame so it can't be pushed in, and added top wedge boards so the window can't be lifted. same as locked window security. I recommended to daughters mom 2016 also works perfect still. I like to write a review especially for an expensive decision that is receiving confusing reviews. I appreciate it when I find a definitive review that helps me make a wise decision. The compressor has a 5 year warranty and I believe my 2 will last and I am suggesting this unit to my son. People saying it doesn't cool as well as a window unit is vague and confusing. You use the square foot capacity to determine if it will work for you. Window fans comes in all capacities and some will be less and some will be more but they come with their own challenges and for me I APPRECIATE THE QUALITY OF THIS UNIT, IT DOES WHAT IT CLAIMS TO DO.

This is the 4th brand of portable a/c I purchased in the past 7 years. It is the best money can buy.I did extensive research for about 4 hours for two days to learn about the specifics of a/c units rather than the advertising it tells you.I researched that the a/c needs to be at least 14,000BTU’s or it will be weak, it needed to be energy efficient which it is because it only uses 1,300 Watts. I had no idea as a women what all this meant but by the end I was an expert. I also liked the reviews about this product and how customer service is great. And it has two vents hoses, that’s got to mean more power. It’s quieter than the Black and Decker I got for $400 couple weeks ago without doing much research, because that one sounded like a broke refrigerator. This one is the same low humming noise as the other a/c units but twice as strong. I liked that this one had M3 filter as I have allergies but also that it was in stock rather than waiting after the heatwave for the other model at the end of September. This one has 91 pints of water capacity to hold in the overflow tank rather than the other model which has 101 pints capacity, which just means you might have to empty it couple days sooner than the other one. It apparently depends on how many bodies are in the room. Family of 4 or more, go with 101 but couple people or less 91 is fine.The unit looks elegant, the plastic hoses are super sturdy and don’t fall out of the window openings and in 20 minutes the temperature of my living room went from 82 to 75, but mostly the humidity got filtered quicker than the other units could do. Oh, and the remote control comes with batteries. Who does that anymore.So out of all the units I saw in Costco, Bestbuy, Target. This one is the best. You will not be disappointed with your purchase. This is coming from an owner of a previous a/c made by De’longhi, Honeywell, Black & Decker and now this one.

Original product failed after five months of holding a ten by fourteen by four feet crawl space at 66 degrees. Customer service promptly sent a new unit to me. Unfortunately I expect this unit will fail, too. I have not found a portable air conditioner that will work - any brand. After this next one fails, I will switch to a split pack.

Purchased 4 years ago...we've been using it for several months in the summer months and it works great for cooling our bedroom to sleep comfortably. It really puts out cold air rather quickly -- we only need to put it on for about an hour before bed and the whole room is cool. Highly recommend and would purchase again!
