LG 10,000 BTU Through Wall Air Conditioner

efficiently cools medium sized bedroom. Quiet and easy to install

Unlike some of the other reviews, my unit arrived via UPS in fine shape. The packaging was robust and in tact. It was dropped off two days late by a pair of UPS employees who informed me “It’s heavy.” They were correct. I scooted it inside and enlisted friends to help me get it upstairs and into the wall to replace en existing, super noisy unit.

The awful instructions will not accommodate all wall sleeves. Ours are 31 years old and are much taller than any of the newer styles. The instructions do not outline WHY you should place a small piece of foam here or there, instead opting for tiny diagrams and poor English. Explaining a little bit of the why is very helpful to those of use who are mechanically inclined. Only after getting all the foam in place inside the sleeve did I realize the new LG is 4”+ shorter than the wall sleeve. What a pain.

It looks like they designed the buttons to be used while looking down at them. Our unit is mounted high on the wall and you must hold the remote up as high as you can and angle it downward to get it to work. The bottom of the temperature setting readout is obscured because it’s angled upward.

Overall it is a quiet unit. The interior fan is loud on speed 3, but that’s expected. The compressor makes a thud when it turns on or off but is otherwise quiet in operation. The front grate rattles intermittently because it’s a poor design and cheap plastic. The clean filter light illuminates every 2ish weeks because it counts 250 hours of unit on time, not running time. The coarse dust filter hasn’t been dirty yet. In energy saver mode it may not run the compressor for hours if the room temperature is acceptable. The fan comes on briefly every 3 minutes to check if the room needs more cooling while in energy saver mode. This is nice because it’s not wasting electricity but also annoying because it’s always there as a reminder of how long you’ve been lying there at night trying to fall asleep.

Temperature control is fine. Setting it to energy saver and 69°F renders a high of 74°F and a low of 72°F. This very acceptable since I don’t want it cooler than 72° anyway. The unit pumps out cold, cold air and the fan moves plenty of that cold air.

Overall it works well and is relatively quiet. It had given us no problems for the whole summer. It needs better instructions, a tiltable control surface and higher quality exterior components to garner that fifth star.

I recently purchased 2 of these a/c’s here on Amazon. When I received them, the packaging was almost destroyed and one of the a/c’s didn’t work (Ironically, the one that did work was the one in which the packaging was completely soaked and falling apart). I returned the non-functioning a/c and received a new one promptly from Amazon. This a/c also did not work. The first faulty a/c’s compressor would kick in, but the fan didn’t work rendering it useless. The next faulty a/c’s fan worked, but not the compressor. Amazing…

SIDE NOTE: I did call LG to see if they could do something about this (I had read that LG is notorious for bad wiring and that a simple wiring connection in the panel could fix the issues). They got all of my information (including the model # and model information – I corrected the guy on the phone 3 times that it is a 9800 BTU unit, not a 10,000 BTU) and they sent a repairman out. He walked in, took one look and said that he wasn’t allowed to touch the unit because it’s under 10,000 BTU’s. So, LG is not helpful at all when it comes to their products. Glad I took the day off from work to be home for the repairman…

I’ve now returned the a/c outright, but kept the functioning unit.

However, the working A/C is now starting to have issues just a couple of months after installing it. The compressor keeps vibrating at random intervals causing a loud metallic clanking sound. It’s now woken us up several times in the middle of the night. I’ll be contacting LG to see if they’ll do anything about this sense it is now outside of Amazon’s range of return. But, I know how that went last time. yay… (Will try and update here when I’ve talked to LG).

With the knowledge I have now, I wish I had never purchased these units and will definitely NEVER be purchasing an LG A/C ever again.

ANOTHER SIDE NOTE: When returning to Amazon I was initially charged a restocking fee citing that the unit was damaged (Amazon graciously reversed this charge and I’ve now received a full refund). They didn’t say what the damage was (other than a non-functioning product), but, I did notice on all 3 of the units I received that the black metal grate on the back was bent (this is my only guess as to physical damage). This is due to the fact that #1 – it’s very flimsy metal, and #2 the packaging. There’s nothing in the packaging to keep this metal from bending. A slight shift during shipping and delivery would easily bend this. So, if you order this (and I hope you don’t) check it when you receive it and take a picture and immediately send it to amazon. That way if you have to return it, you’ve already made a note of it with them.

Save yourself the hassle, spend a little more and buy a Frigidaire or something better. You won’t regret it.

I had somebody install it for me so I can’t tell you how difficult it is to install but it cools off the majority of my 650ish sqft apartment & only raises my electric bill by around $20.00. the filter is washable & in my home needs to be cleaned ever month or 2. I’ve had it for almost 1 season.
