1 out of 5 eggsLG not for me

Pros: looks well made; great price thanks to newegg

Cons: YeAAAA new air conditioner arrived today... Booo.. it sucked putting it together, only to find out that it didn't work... called LG and talked to a brilliant girl (not) who was probably reading the box (or at least her computer screen) to give me stupid answers.. her best idea was this : that i should leave it plugged in, and on for 2 hours and it will probably start working on it's this is after i held the phone up to the unit to let her hear the low noise of an appliance trying to work..compressor kicks in, but no air from either the fan or a/c setting... i told her i didn't really think it was a good idea to leave an obviously damaged electrical appliance plugged in..and turned on... she assured me it was ok to do so.. after hanging up, i took off the front grill, put my hand carefully into the unit and manually moved the fan blades..clunk, clunk, clunk, was trying to spin but seemed to be hitting something.. took it out of the window, took apart the chassis ..again, as i had to take it apart to assemble it..(as per instruction manual) grrr... what i found was shocking.. the fan motor, (very similar looking to a car fan) was not screw'd into the housing.(all 4 screws were missing !!!) it was just hanging there and hitting the shroud around it ....and it was hot as hell..too hot to touch... i wonder what would have happened if i listened to her and left it on for 2 hours ?? best case scenario, the motor would have completely burned out..worst case scenario, the house would have burned down with it... LG stands for "life is good." but their a/c is not. at least when they forget to finish assembling it..and obviously they don't test their products before they ship them out of the factory.. they should be called NG good !!

Other Thoughts: LG has a great reputation for quality products.. not sure what went wrong here... i'm enjoying the LG sound bar and subwoofer i got to go with my Samsung TV, but their solution was to send a repair guy out to my house !! really ? i could find 4 screws and fix it myself it 5 minutes, but i would never leave that thing plugged in again after it over heated... plus i wouldn't expect it to last a full life after what it had already been through.. it went back to newegg with the prepaid postage label that they (newegg) emailed me...

5 out of 5 eggsawesome

Pros: quiet and keeps my place cold

Cons: mounting in my window was kind of a pain.

Other Thoughts: I don't have much of a ledge to support the a/c on, so I built a support for it which made the install take a little longer than i would have liked.

I got this unit to keep the living room of my apartment cool because 3 computers running folding at home produces a ton of heat. Not only does this thing counter the heat from the computers, it keeps my place cool. When im not running folding at home, it will keep my 1200 ft2 apartment cool with a couple of extra fans circulating the air. its 90F outside and its very comfortable in my place again.
