LG Dual Inverter Portable Air Conditioner, 500 Sq. Ft

I love LG. I think they don’t put out a product unless it is one of the best in its field, and that’s why I decided to trust them again when I needed an indoor air conditioner. The reviews of various companies all had good reviews, as this did, and it is otherwise hard to choose – so I just chose LG and I’m happy, so far, that I did.

I wanted an indoor unit specifically. My concerns with that type of unit were 1) do I have to empty water buildup, 2) efficiency or cooling ability 3) power consumption, specifically, will the cord get hot when on continuously for days…

So all three concerns are satisfied, cord/wall stays cool as does the unit, no water buildup or emptying (on cooling mode) to worry about at all, and unit pumps wonderfully freezing air into the room – quickly cooling a 400 ft space, and even supplying cool dry air to a larger space. I am sufficiently impressed. If it never breaks and is always the same trusty unit that it is now, I would consider it perfect.

The cons? Well, it is certainly louder than my old energy star window unit. I don’t mind white noise at all though for sleeping, and it is not too loud for that. I would like a lower fan speed option, that is quieter, but I doubt other models are any quieter. I believe I read the fan has to run to wick the water buildup away – so a low setting simply might not be possible with an indoor unit of any kind. In any case, it does have a low and high speed.

Suggestion: the remote could use an led display light. You pick it up in the night to turn the fan to low, or turn it off – and you can’t see squat, start guessing, and hitting all the wrong buttons. So, I just had to learn where each button is, no big deal, but light would be improvement.

Overall, it has reliably and impressively cooled my space, sealed off my window perfectly, jumps to life every time I ask it to, and worked perfectly as advertised. Would definitely recommend.

Update after two seasons: still going strong, still cooling beautifully. HOWEVER, unbelievably the unit leaked spots on my carpeted floor, partly ruining that section of carpet and leaving a strange rusty stain. I place a baking sheet under the unit to catch the water, and that has been working through season two. This year, there was only a few drips in the pan which evaporated before they had to be sponged. I guess the previous year was particlularly humid, and it needed sponging every few days. Still, the unit was kept on flat out lowest setting for months and did not fail.

When I called LG about the leak, I stated the manual says it is supposed to turn itself off when reservoir is full (so it doesn’t destroy your carpet right??!!! ) and we wen’t round and round in misunderstanding in what seemed to be different languages. I was directly to a website – unbelievably – which demonstrated how to plug a hose (not supplied) into the unit which leads to a drainhole – yeah!!! As if I live in a warehouse with one of those in the bedroom floor! Un. Believable.

That said, it is still working great, on it’s cake pan, cools perfectly, none of the other 1 star issues I’ve read about thankfully, and I found an added bonus to indoor units in general: doesn’t matter if its 45 degrees outside. If the sun has heated the upstairs all day and you want a blast of cool, you can just blast it on and cool everything down. You can’t do that with a window, or central unit as you can’t run it below 60 or so, or risk damaging it (and a window compressor with sensor won’t even turn on). But this one you can, great stuff. Also, I compared it to central HVAC electric usage, and it seemed to be about even, or even less, so it wasn’t out of control in that regard, though it doesn’t waste energy heating rooms you don’t need.

Llevo unas semanas y se destaca entre otros aires que he manejado.
Cuando está a mínima velocidad en modo frío, he llegado a registrar 52-51db. En una parte de la noche se apaga el compresor y he registrado 45-46db. Todo lo anterior medido a una distancia de 1 y medio.
En cuanto a enfriamiento en un cuarto de las medidas que indica el fabricante, logra bajar y mantener la temperatura de forma eficiente. Un cuarto de 12 m2. a 28 grados la bajó a 21 en 20-25 minutos, con potencia máxima, después quedarse en velocidad mínima.

I just purchased my 3rd one of these a/cs.
They look great and they work great. They are very quiet!

When we ordered it was sooo hot out but once delivered it had cooled down considerably which was strange weather for Vancouver in July! We had to wait for a hot day and it finally happened….so easy to use the remote. It’s very quiet and it cooled us down quickly. This is one of the best things we’ve purchased and it can get as hot outside as it wants and we’ll be comfortable, safe and cool in our home.

Had to get an AC to tolerate heat this summer & opted for LG after conferring with friend who’s worked in HVAC for 7 years. Solid unit. Was heavier than I expected, but does perform well (so far) Was lucky and there was no shipping damage apparent when I got this. Make sure to check the bottom drain and properly seat that rubber plug and gently tighten the screw assembly that snugs it into place before operation.

Minor thing I’ve yet to sort is turning the condenser fan on. I get the ON as it says in the manual but when the appliance is powered off it shuts down instead of hearing a fan run. Will update review should things change or I notice excessive leaks or things negative reviews mention.

Update: The 10 minute condenser fan setting comes on if you turn unit off by remote. Doing so on the control panel seems to shut down unit immediately, even with this feature on. It cools below the set point exceedingly well during the daytime; but at night seems to creep up above 70. It also seems to keep the rest of the apartment space from going superhot; despite not being open to the main floor most of the time. So far, I’d recommend this unit based on how solid it’s performing. No indicator to empty tank yet; and do wish the access point for that was a bit more reachable. A removable tank would be ideal but I’m not sure if LG’s engineers can accomplish such a feat.

I bought this as the top rated portable air conditioner on Wire Cutter. I use it in a 1000 sq ft apartment. Set up is simple (just stick some insulating foam stickers on the vent panel and place it in a window, and attach it to the unit with the hose). It works just as well as any in-window unit with the benefit of being able to move it to another room easily if you need to. Though note, if your windows aren’t all the same width moving it will more difficult since you’ll need to resize the vent panel, which may require adding/removing the insulating stickers.

It very quickly cools my largest room, but it takes a while for the cold air to reach other rooms. It’s not central air so this is expected, and I’ve just been rolling it into my bedroom on hot nights.

The LG app is nice, you can monitor and control everything about the AC from your phone. If you’re out on a hot day, you can turn it on before you get home and come home to a cool apartment. I tried the Alexa skill as well. It works but is a bit clunky. Instead of just saying “turn off the air conditioner”, you have to remember to say “ask LG to turn off the air conditioner”. I wont hold that against them though because it is probably a limitation of Alexa, not the LG skill.

One nitpick is mine came with the wrong size foam pieces for the size sides of the panel (they weren’t long enough). Not a huge deal, there was enough left over from the other strips that I could cut and use them.

Also a note about the other review that complained that the unit still needs a vent connected to a window – this is true of ANY air conditioner. Unfortunately, these units can not defy the laws of physics – the heat has to go somewhere!
