We ran into a snag with our purchase. Our portable A/c unit came with two sets of extension panels and no Window vent panel. We reached out online through chat and we’re able to request parts without having to return the unit. The one problem the replacement parts we received which were the vent hose, window panel, and window extension panels weren’t the right ones for my model. Thankfully I was somehow able to snap my vent hose into the window vent and It that did fit. I’m still a fan of LG products. The customer service person was pleasant and did get parts to me quickly.
