Lifesaver

ATRD 9/8/2022

A few weeks ago my HVAC unit went down hard. With supply side issues being what they are it was difficult to find the motherboard and motor to get it back up again. This occurred this past August when daily temperatures where I live in Florida were averaging 95F every day. I went out and bought this window AC unit for my bedroom and it literally and figuratively saved me from heat exhaustion. It took 8 days for my AC service to find the parts so the purchase of the unit was money well spent. As a plus factor I can subsequently use it with my home generator during the next inevitable hurricane hit in my area

Difficult to install

LG8021HRSM 7/3/2022

My husband installed the unit but he had to uninstall the guts of the unit just to get to the two clips for the right and left curtains. Maybe they could have been installed at the factory It was also very difficult to get the correct department to get help with setting up the Wifi.

Year round function

IAmKEspinosa 3/1/2022

Bought this for my make shift home officeaka my converted shed and love that I can use this year round while its still cold out the heater is great and when it gets hot the A/C is nice and cold. Was hoping it would be a little quieter but its still quieter than the older LG window unit I had before. Love that I can use it with the ThinQ app too so I can set it to pre-cool or pre-heat before I head in there. Overall very satisfied

Great in theory but poorly made

Lauraakagumby 9/30/2021

I have only had this 6 months and its defective and not working. Its the perfect size and features it is so disappointing. Im still waiting for lg to do right by me. Its installed so I cant get stickers nor can I have a hole in my wall while I work on getting new and finding someone to do the work again during COVID is a nightmare as it is in our property two state away. Not cool. I dont have time to get back there.

Great cooling

Suzie2you 8/4/2021

I bought my 7500 a month ago and it does a fantastic job of keeping our big bedroom and an adjoining room cool. it is quiet and you dont even have to get out of bed to adjust anything. It runs quietly. I cant wait to try out the heater part but wont do it in this 100 degree weather. Thanks lg
