this a/c is crap! leaked & when manufacturer was notified they had it shipped back to them to check it out. Surprise! no leaking for them! They sent it back to us & refused to refund our money! Claims this machine needs to be on hard floor surface, not carpet! Seeing as I have carpet in my house I would never bought this if it had stated no carpet use...... now I am stuck with an air conditioner that the company says there is nothing wrong with it but I cannot use it!!! Go figure!
