  • Came damaged

    This was dropped before I got it, which bent it all up. HSN is replacing it and I am Not paying for shipping. Yea!!!! I am looking forward to getting the replacement. I gave the stars for HSN service because they were right on it and were the ones who told me they would pay for return shipping.

    This unit has a $89 annual operating cost ,YES its true ! Unit is super COLD ,QUIET and has WIFI ,so you can operate abroad if wanted ! I have a CENTRAL UNIT in my home that works perfect but is 25 years old ! So looking to cut the cost of Light Bill ,and it will be cut in half NO DOUBT ! On Energy Saver it goes to *60 degrees and fan wide open ! I have a large home it cools the whole thing to SWEET ICE BOX CHILL on Energy SAVER also ! Has remote that operates fan /temp timer /and modes ! Also all the functions are built into the front which plugs into unit ,so if there is a failure ,you simply buy plastic front instead of new unit ! This is my 2nd L G the other 7 years older ,I have had them all ,you cant beat L G PRODUCTS ,they have oversize ELECTRICAL PARTS throughout all of there products to avoid returns and breakage ! Look to L G for any appliance and I promise you will be happy U got it right the first time ! A 12000 BTU will COOL any decent insulated building !
