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

This is something that your own research should have come up with There's two basic types of potable AC. Those that take the air inside the room (intake) and use that to cool off more air (expelling the inside the room air ... outside (via a single hose) and The dual hose units that are more expensive but use the outside air to cool the unit (intake) and a second hose to take air from the inside of the room and then chill it even further. These are better units and you're not wasting energy as you're blowing the inside cool air back outside the home. IF you have the single hose type and it's humid, you're going to be collecting condensation off cold surface inside the unit. (the dual hose types accumulate less water from the inside of the home as it's assumed that the humidity is mostly outside. This is one of those things you have to know about and look for, as it's not advertised and written down. Some units can have a plastic tube attached to the drain and kept elevated so that the condensation is constantly drained into a bucket. A well designed unit will make this easy.... the next thing you should know is the BTU's which is basically the cooling power the unit performs at. The more BTU the colder the air coming out of it. IME, a 10,000 + BTU is needed for a single room that gets heated up in the summer. (OF course it's a smart more to try to keep the heat from getting into the room first by using shade screens and insulation) I got a [Whynter ARC 14SH](https://www.whynter.com/product/compact-dual-hose-14000-btu-portable-air-conditioner-heater-arc-14sh/) 14,000 BTU (9,200 BTU SACC) that does both AC cooling and heating for the room. [The SACC is a different rating system that is said to be more accurate vs the old system to rate how the conditioner performs in conditions of 80 degrees Fahrenheit and 51 percent relative humidity. ](https://www.sylvane.com/ashrae-vs-sacc-btu-ratings.html?srsltid=AfmBOorwsm7ryVOpikJyBDDyxodoAk3yeDrvsg7UqSomc5Aho_yIQgOR) So be aware of the two sets of numbers and how some brands will only pump the larger number. [It works well (video review)](https://youtu.be/GO7ZcyXjzoM?si=AJjm2AdFYaqvVrKo) The ONLY negative thing I have to say about it is that the condensation collection drain is down at the BOTTOM OF THE UNIT and that you really should have this up on a milk crate or something with a clear hose (1/8th") draining into a bucket. IF you use a 1/8th" plastic tube (home depot) you can connect to the drain and have that flow into a bucket (easy) When it was HOT and HUMID this last week I was emptying the thing once a week (automatic shutoff when full) [This putz is using a dinner plate for the water, I can tell you I get multiple liters of water coming out when the tank is full (and the AC stops working).](https://youtu.be/cFH9FUyArMM?si=5C4upnkbdprXAu-5) So do not listen to this clown. *I'm putting it up so you can see the amount of bad info that's out there.* The other thing is that I didn't put the air filter over the outdoor air intake (extra charge for that accessory) and so there's some dust and film that came out with the water tank draining. Doesn't seem like too much of a problem, nothing I can't clean up later. At home, you should get some light cloth (maybe cheesecloth) to cover the air intake with to help with that -which I'll be doing. That's about it. All things considered, I've seen worse products out there with worse documentation and BS shilling video's. I've had multiple portable AC's and that this one works well and can regulate the temp inside the room for heat and cold.

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.

We bought the 14K btu Whynter right before the hurricane hit. It is cooling the family room quite well. My window opens side to side so there is a huge gap above the hose outlet. And the unit comes with panels to fill the gap but it is hard to make 3 pieces align and be air tight. It is leaking air pretty bad so I will have to build something a little more leak free after this is over, but we have bee very happy with it.

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.

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.

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.

I've had a Whynter dual hose AC unit running for a couple years now, works great, cools a lot and pretty affordable

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.

Any dual hose one will be more efficient and possibly more quiet. I have the Whynter Arc. It does a great job. Some people may find it noisy but it doesn’t bother me. But it IS large so not easy to lug between places.

Whynter. They’re also packed very well in the box.

I owned the Whynter one size smaller for 2 years. I only ran one hose (intake) not two. The dehumidifier works while the ac unit is running. I never had to drain it and the instructions said this unit will evaporate the excess water and it did for me. Most of the time the dehumidifier cooled the room perfectly fine and I also live near the water and it is humid. Maybe it didn't need draining because I only ran one hose, I capped off the other with the cap that came with it and it indicated in the instruction it didn't need 2 hoses. I was pleased overall with the unit. It cooled 700 sq. feet fairly well.

Most are made in the same factory and have different labels slapped on the front, similar to other household appliances. I personally have had good experience with Whynter units. They are known as one of the more reliable brands. As others have mentioned, you should look into dual hose units. They cool the room more efficiently than single hose units by preventing negative air pressure in the room.

Single most important thing: Dual hose units maintain the pressure balance in your room. Single hose units vacuum hot air into your house. Next most important thing. Buy new. These things are consumables. I like my Whynter brand units. They've lasted far longer than I thought they would. I also like my Hisense unit. It is nice and quiet.

The whynter has a slightly higher CEER compared to the DUO (14.2 vs 13.8) for what it's worth. It does a great job of supplementing AC in my home office without of electronics.
