Quiet, efficient split; but mold issues and bulky.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Meine leitet das Wasser über den mitgelieferten Schlauch in meinen Putzeimer.
Ich habe eine Midea. Nein, es ist eine Monoblock, hehe. Gekauft, weil als leise beworben. Abdichtung gekauft, damit der Abluftschlauch einigermaßen gut abgedichtet nach draussen bläst. Frischluft zieht sie über die Badbelüftung. Ist relativ leise, aber nur relativ. Deshalb steht sie im Schlafzimmer. Im Wohnzimmer bringt es max. 5 Grad weniger. Aber: die Luft ist deutlich trockener, und allein das verhindert sehr gut das dahin köcheln im eigenen Saft.
Meine saugt relativ kühle Luft über die Badbelüftung an. Klappt gut.
Check Slickdeals, I recently bought a refurbished 12000BTU Midea for $200. I live in California, currently 95F, and for an uninsulated garage of that size, you'd want at least a 12000BTU Midea if not the 14000BTU. There's currently a 18500BTU mini split on sale for $550 that be optimal.
I have 2 of them for the better part of 7 years. A 12k btu and 9k btu. Midea and Defy. One in my bedroom (4m x 3m) and one as a roaming AC. They work very well. I don't mind the noise. I pretend I'm on a flight somewhere. I won't do wall AC because I'm renting and my landlord is cheap and won't pay. This will suffice. It's better than nothing. I sleep like a baby.
Yeah, those are not ultra efficient but they work, I had it for the last 3 summers including this and works great! Also it was cheap in that time, 312 EUR (Midea, 12000BTU). I used a plastic adapter to cover the window, of course close the cortins and close the other room doors to increase efficiency. My electric bill had no changes I don't turn it in all the days, just when it is 30+ outside (like today). And my cats are now safe! (First summer one of my cats throw up because of the heat)
I have the same combination and it works, it's not ultra efficient but you don't need to turn it on all days.
Got the same one from costco and makes gaming in my upstairs office cool during the hottest days of summer! And no water drain!!!
Never a single hose, dual hose inverter unit if it must be portable (Inverter units can be quieter and use less energy because they don't just blow at full power unless needed) I would get a window unit if you can. make sure you get the correct size unit. My midea doesn't leak, but I don't think that's actually a wide scale issue lol.
