    • 19 inch window height minimum for the large unit. Install with a downward tilt to the exterior.
Size: 23,500 BTU
Measure your window opening height. Do not rely on the product dimensions in the listing. The product box says the window opening must be a minimum of 19 inches for the 2-ton LW2422IVSM! My 32x32 garage window did not open large enough so I permanently removed both sashes to install the unit. I built a new internal window frame from 2x4 pieces. Because the unit weighs over 100 pounds, I first purchased and installed the Ivation Support Bracket https://www.amazon.com/dp/B07CZH178M which was pretty simple. Some small support brackets are included with the air conditioner but a sturdy external bracket gave me piece of mind and reduced the possibility that I would drop the whole air conditioner out the window during installation. The guts of the air conditioner slide out of its cabinet and the empty outer shell is next installed in the window. Then the air conditioner guts are slid into the installed cabinet. This is a good method so that the lightweight cabinet can be adjusted and secured. The unit should tilt down slightly outside -- about 2 degrees or 0.5 inch slope -- so the condensate will drain properly. I removed the side curtain guide at the top of the cabinet and did not install the included side curtains. I chose to cut 0.25 inch clear polycarbonate sheet to fill the rest of the window opening. 0.125 inch polycarbonate sheet would probably have been adequate. Initial startup had about ten seconds of troublesome fan noise which disappeared on its own. Now the unit is very quiet and blows super cold air. Super cold! The controls on the unit and on the remote are simple enough. The installation instructions were understandable. ... show more

This one came Damaged! LG makes a great product that will last 5 years. The new refrigerant is suspect but this unit is listed as 23500BTU and the one it’s replacing was17500BTU they are identical in every physical way but the new one draws 1/3 of an amp more so a little more refrigerant maybe the answer. Now the good stuff this thing slings air without a jet engine high pitch it’s slow woosh sound that disappears when talking or listening to the TV. Power wise it only uses 3.5kw to cool 1200sqft from 80 -65 degrees in 1.25 hours. LG app works great to keep an eye on cost. Eco mode is kinda a gimmick one you use the AC at or beyond 80% of sqft because solar gain heating the house makes the cool setting the cheaper choice. I’ll put pictures of temp of air. UPS (us poor saps) smashed it all to hell, see pictures. Treat these like a fridge if you put them on the side wait 24 hours so the compressor isn’t damaged from oil somewhere it’s not supposed to be. Just know 5years is it but it’s a good 5 years if you clean them. ... show more

    • Great cooling
Size: 23,500 BTU
The greatest investment i ever made for my workshop. I have a 40'×40' workshop in Arizona. Summer time temperatures can reach 120°F+ making nearly impossible to work in the shop. To make matter worse. I have automotive chemicals and and other part stored in the building. With this A/C I can run it non stop at 86°F 24/7 on energy saver mode. Then turn it down to 75°F or lower while I'm working. It's been 2 years now and it's still running strong. ... show more

    • Cooled an entire 1200sq ft house
Size: 23,500 BTU
Solid unit turned the office into an ice box while cooling the rest of the house too. Needed to use a step down transformer box (240v to 110v at 5000watt). The dual inverter really kept power consumption down. Our central AC went bust last summer and that thing was eating $150-170 of electricity every year! This LG 23500 BTU unit was only eating $80-90 !! Could not ask for better efficiency in Florida heat! Loud? Not as much as the horrific Frigidaire units and the hum it generates is actually soothing white noise rather than a loud compressor noise which is otherwise typical from such units.. this was the best AC I’ve ever used. The Alexa integration is practically non existent however so be prepared to set a good schedule for off/on and various temps based on your seasons within the ThinQ LG app itself. Alexa can’t do anything because she always thinks the unit is in a mode that can’t be adjusted when you’re using the ‘efficiency’ mode which is what utilizes the dual inverter system, to keep the cooling variable and less power hungry. She can turn the unit on and off if needed and also switch modes to COOL or FAN and then you can adjust temps and fan speed and then switch back to the efficiency mode. Not an ideal way of handling things but it works. 8/10 overall I loved the reduction in electricity cost and the sound was totally bearable. Super great unit ... show more

    • died in lesss than a year - no replacement
Size: 23,500 BTU
Died in less than 1 year, still under mfr warranty - mfr sent over two technicians to tell us why it could not be repaired - ( I am an engineer - all lies in my opinion) - one technician did not even work on air conditioners. Turns out the main control board fried from a 1 leg of 220v brownout - and the real reason lg would not repair it is because they did not have any replacement control boards. none in the US - none in Korea. LG refused to send a new replacement unit. So now I am left hiring an attorney - Last LG crap I EVER buy ! UPDATE: 5/16/2026 Encompass, LG's US parts supplier, still does not have a replacement control board to buy. I was also reading somebody's review below about the serial number and wanted to confirm: The serial number is a sticker they stick on the outer case of the unit. Once the unit is installed, the sticker is either completely hidden, or destroyed from installation. Luckily, I actually noticed this before installation, so I pulled the sticker off, made a copy of it with the laser printer, laminated it in a plastic cover, and taped it back on the unit in a visible location. (Little good it did.) The first refrigerator technician that LG sent out, said they will not repair it because we lived near the beach, and we needed to read the fine print in their warranty. I thought a complete review was important . ... show more

    • Great air conditioner! Low maintenance!
Size: 23,500 BTU
This ac was a life saver. Our central ac died and we couldn't afford to replace them. The window unit was just the right size for the bedrooms. They are working so well and such little maintenance we may never replace the central ac!

    • Good unit, rough shipping
Size: 23,500 BTU
I received this on time, the box was heavily damaged however the actual unit looked to be in pretty good shape. Giving this 4 stars instead of 5 mainly because of shipping and condition the box was in, as well as how it appeared that this unit may have been previously opened and then returned. I purchased the 23,500 BTU unit and installed it through our wall to replace our much older Amana. All in all, I am happy with how much cool air this provides to our upper level, as well as how very quiet it is. I am hoping this unit will last several years. ... show more

    • Works Flawelessly would 100 percent recommend
Size: 23,500 BTU
We are completely satisfied with our unit—LG has truly come a long way! The system works flawlessly, and I love that I can control it remotely from the app so i could be at work or anywhere I go, allowing me to turn it on or off at will. The unit comes with a different plug, but we already had a solution in place by cutting off the cord and connecting the wires directly to our breaker, which worked perfectly. Overall, it cools exceptionally well and performs like a champ. 🏆 I would definitely recommend this unit to anyone looking for reliable and efficient. ... show more
