Portable Air Conditioners - Why you shouldn't like them

Portable ACs are borderline scams because the hot side is inside the room it's trying to cool, among other reasons[0]. [0] obligatory TC rant: ▶ this video

If you are in the market for a portable AC I highly recommend you watch this video first: ▶ this video People seem to be catching on this and some brands now offer portable mini-splits ACs, I just bought this one (waiting for it to arrive though): link However they are still quite expensive.

Generally nothing, but those are 1. loud[0], 2. very inefficient and ineffective[1], 3. in the EU there are no dual-hose units for whatever reason. I still use one but it's very far from ideal. [0] so loud that neighbours might complain, I had neighbours complain about my computer fans running 24/7. [1] ▶ this video

No doubt those will be single hose stand alone units, the worst kind [Portable Air Conditioners - Why you shouldn't like them] by Technology Connections ▶ this video

Some portable A/C units do send hot air outside, and some don't. The two-hose models AFAIK are the latter type (although the un-insulated hoses are wildly inefficient) ▶ this video

not op but was in same situation for few years as in my region A/C is somehow luxury and a lot of landlords don't mount them. the issue with portable A/C is that most of the units needs to stay inside apartment, the cooling happens by compression/decompression of coolant, which produces heat and cold. so the A/C unit is producing additional heat that it needs to chill, which makes it inefficient. also these units are loud as fuck, most of them above 65dB. so if you are in need, look for units that have the ability to channel cold air to the house from outside. otherwise you should always avoid portable A/C as it is really inefficient. here's better explanation: ▶ this video

If anyone is considering buying a "portable" air conditioner - the kind that rolls around on wheels - know that they are pretty awful. If you must buy one, at least buy a "dual hose" version. Single hose versions suck air out of your house, causing fresh, but hot, air to be sucked in through all the vents, gaps, and cracks in your house. Window units or "split" systems are far more efficient and work much better, at the downside of cost and installation fees. Technology Connections has a very good video (with perhaps excessive detail, but it is very interesting) about them, here: ▶ this video

Portable air conditioners are bad. All the hot components are in the room with you and it takes air from the room and blows it outside. Technology Connections has a good video about this: ▶ this video
