    • Great product
Color: Bright White Size: 18000 BTU Style: Wifi 230V
Received the air condition heater two days before they said it would be delivered. Very easy install. The control panel is easy to see. I love the fact that it has an oscillating vent. I would definitely recommend this to everyone. Definitely a good price. I checked our local places for the same brand less BTU was a little bit more money. When I came here and found the 18,000 BTU for this dollar amount I jumped on it. ... show more

    • Don’t buy LG
Color: Bright White Size: 18000 BTU Style: Wifi 230V
AC worked for 2 months in 2024. Turned on in June 2025; no cool air, no error code. Called LG and told unit under warranty; would send repairman in 2 - 3 weeks. Nothing. Called many more times and finally told no repairman in my area & could I find one. I already had called every repairman within 60 mile radius. I called many more times. Now offered a replacement after complaining to escalation team. I had to complete form on portal link asking for same info provided earlier. I provided receipt, sticker on AC unit, picture of unit etc. Told to be contacted by transportation team in about a week. Called many more times: told to wait 2 -3 weeks. Nothing. Called again, filed complaint with LG. Finally spoke to Alexis on Presidential team. She said AG out of stock and offered reimbursement. I completed form on portal link again agreeing to direct deposit reimbursement. I was told would receive secure link in 2-3 days. Nothing. Three weeks later received text saying to complete form on portal link again as I had done before; no explanation why or indication of error on my part. Called LG and not allowed to talk to Alexis on Presidential Team. Told I’d received text in 2 days with explanation and resolution of problem. Two days later I got a survey to rate how well problem was solved. Problem was not solved. I called LG, said all they could do was send escalation e-mail to escalation team. I called again and told the same thing. Three months later and many phone calls = no repair, no replacement, no refund, no explanation!! ... show more

    • Nice A/C
Color: Bright White Size: 18000 BTU Style: Wifi 230V
Nice 18000 BTU A/C very quiet we have not used the heat pump side. Installation was easy we installed through the wall I do recommend using the angle brackets if you are doing a permanent install as it is a heavy unit. You will need a friend for lifting. The enclosure can be set with the unit removed then slide the unit back into the enclosure for ease of installation. (Instructions are in the manual) ... show more

    • Best window unit ever!
Color: Bright White Size: 18000 BTU Style: Wifi 230V
These Louisiana summers are hot, humid and miserable. The LG air conditioner I bought is keeping me cool though.

    • Takes a While to Cool
Color: Bright White Size: 18000 BTU Style: Wifi 230V
I have an insulated 560sq ft garage I installed the AC in. I'll turn the AC on and go back out in about an hour and it's still warm. I'm in the process of setting up my workshop and will see what happens when the AC runs for a while. For a 1000sq ft AC I figured it would cool down the garage fairly quickly. Also, the vent louvers won't stay where I set them. I'll set the louvers fully open and over time the louvers move downward blowing the AC down towards the ground. The unit needs a new face plate, front cover. ... show more

    • Very weak air conditioner
Color: Bright White Size: 18000 BTU Style: Wifi 230V
This is a very weak air conditioner. I bought it to supplement the other two in my home, a 10,000 BTU and a 14000BTU, both of which are stronger and more efficient that the 18000 BTU LG featured in this review. Choose something else. This thing stinks.
