Oh no. It’s a new version of a well-established product that trades efficiency for convenience. But this time, it’s more than just being cool. It’s about cooling.
Seriously, either we need to get more awareness of how dumb single-hose portable A/C units are, or we need to just use window units whenever possible. While I know that there are times a portable unit is the only option (remember, I’m in that boat), it seems that only very high capacity, premium machines have the facility to use two hoses. Which is frankly stupid but then again that’s what I’m trying to tell you now.
How about some links? Ya link links? I’ve gathered some for you:

We don't like them but we don't have much if an option in temples. They aren't built to have air conditioning and that's probably a good idea since they're full of incense smoke. So once a year when everyone who has offended grand duke Jupiter goes to get blessings, they pull a few of those out so it can cool the place down .

What's your thoughts on the new DOE BTU rating standard? It seems like this fixes the issues with judging single hose units by taking into account the negative air pressure and how much heat the unit itself generates.

My HOA doesnt allow the ones that hang out your window so i need to use a portable one

In AZ when it's 113 degrees and your central air breaks down an it will be 36 hours to get the repair, a portable AC is a good backup unit to cool a room till the central AC is fixed.

awesome video, I've learned how air conditioners work
I have 2 units. One window mounted which I use for cooling. The other, a mobile one, I use as a dehumidifier. I find that on that setting I get better cooling than when it's on cool. The big factor in my area is the intense near tropical humidity levels even though I live in Québec.

I’ve bought 3 different brands of standing air conditioners with more and more btu’s. They all do a horrible job cooling on a hot day. They’re just better than nothing.

would love for you to make a recommended brands and AC units video to help people get something that is good bang for your buck. my rental house has no space for a standard AC unit so i need to get a portable one. I understand that they are not the best from what you explained but maybe you can tell us what are the stats to look for?

Sadly a year later, and the dual hose models are not catching on.

Blah blah blah, I got a portable air conditioner for my bedroom and it has made a huge difference. Gone from unbearable temperature and humidity to comfort and ability to sleep!
Lynda Stiefvater
You can put insulation around the hose and it helps a lot.
AA RC Day ago
Yeah I disrespectfully disagree. Portable ACs are the best man.
Dacia Sandero guys
My portable AC produced more hot air than cold air. It would be ideal to use it in winter or cold days BUT the awful thing is extremely noisy your neighbours will even think you has a saw mill in the house

I've been using a portable one hose Haiar AC for nearly 9 years. Love the portability of the unit the most. I only use mine during the night and it cools like a charm with another fan to help circulate the cool air to a larger area. Yep, all the outside HOT air is drawn back into your walls during the day. The air is cooler at night so it naturally cools better. As far as high electric bills, the bill stays relatively low because I only use it at night. It also has a heater for winter use 🤔 I never attempted to use it during the winter ....hmmm...🤔 guess this winter I'll give it a try. But so far, so good. It serves my purpose for humid, summer evenings and nights. Happy AC hunting everyone!

I wish I had watched this video before I ordered one last week, I would have gotten one with two hoses. :-( Even though the two hoses are like $100 even more expensive.
Jamilah Hamilton
This guy is so right. I have a portable AC unit in a pretty big room. It’s loud, it leaks, and it doesn’t cool very efficiently. I can actually feel the hot air in the hose going out the window meaning that there is heat coming right back into the house. These are not made for rooms other than maybe a small bedroom. I am ready to get a window unit. I know I’ll be a lot happier.

If you set them up properly and make sure all air leaks are sealed, they can work very well, and for me, i enjoy white noise.

I was surprised how hot the hose got on my portable ac unit. I ended up insulating the heck out of it and it became a lot more efficient at cooling the room

Living in a part of Europe, where we use only vertical windows. So a window unit is not an option. Just bought a portable unit and it works ok. Its better than no AC at all. And btw. it works with the R290, as all the them have to do, thanks to the EU directives...

You forgot to mention another downside of the portable units. They need to DRAIN THEIR CONDENSATE WATER! The outlet valve will invariably located at the bottom of the unit, so in order to drain the water into a container, you have to lift it up; or otherwise hang it over a step!

Just saw this and had to comment. Dual hose inside units, pull in hot air from the outside, and then send the hotter air outside. With two hoses and hot air, you are also getting radiant heat transfer from those hoses, now doubled, into the room you are cooling.

tiny cat I guess it just depends on the user. I rather pay more for the convenience of being able to put it away quickly. A window ac is much harder to put away even though it cools better.

one more thing i hate about portable ACs: there is only one single model with inverter technology (DCI Ulisse 13). Even the mobile split system you showed (sold as EUROM AC here in europe) is an on/off type which is very annoying to sleep with. Please somebody develop these mobile things further. until then, i would only go for a real split or DIY one into a mobile unit.

Why don't they convert the excess heat energy into mechanical energy, instead of just flushing out the heat to the outside. Theoretically it should be possible to cool the air in a room without the need for a hose, but why isn't it done?

What if your broke or your wife does not want a big unit in her front window or bedroom for the neighbors to see? A good portable will work just fine. Here is the key to making one work. You have to have a compatible room. I mean the exhaust tube should not be more than 36 inches to the window. If you need 3 or 4 or 5 feet that hose will get hot! Also the unit should be rated larger than what the size of your room you need cooled by 1/3. You should have a pusher fan near the unit to push air throughout the room. Buy a quality brand. Look for noise and the guarantee! That is it. I have 2 in separate rooms and they work fine and save me a ton of money on cooling. One is permanent and vents 20 inches through the floor. It is in a corner and not noticed. The other is only used in rooms we are going to be in and taken down during the winter. Both work great!

Can't bottle that energy up? But why couldn't we? Couldn't we instead of transferring the coolant to the condenser and just vent the heat to atmosphere use a heat exchanger connected to say your water heater for example? Or perhaps use a thermoelectic generator to produce electricity? It' won't be enough to charge your Tesla, but if the AC could use some of it's own electricity to run the compressor it could make it more energy efficient. Maybe it wont do much, but a saving a little energy is better than just wasting it.

Can I leave that thing outside and jerry rig the hose to bring the cool air in providing no one steals my shit

Awesome information! Thank you for creating great content with useful info. I came across a new U-shape type of AC window unit from another youtuber and immediately thought of your window setup. Midea makes a window unit that allows for better weight distribution. www.amazon.com/stores/Midea/Homepage/page/4F6A19CF-5B7B-4D5A-A739-6EA8B46D4560

Modifying one to have a second hose can resolve some of the issues, but that does add to the cost. It's still cheaper than a mini-split system, but isn't something one should use unless they don't have any better options.

Why do you need 2 hoses next to each other. Have one tube inside the other the smaller tube pulls air in and the larger tube pushes air out. Adjust the sizes of the tubes to achieve similar CFM flows.

I wish I could have a window unit. I own one from when rented in a place that could fit one. But now I own a condo with hoa that doesnt like them and I have crank windows. Which man... crank windows are difficult to put even portable acs in.
