Peace be upon you,, I have a General Supreme 30 unit air conditioner. It is working and very cold, and it is guaranteed. I have had it for only a year and a half, and the purchase invoice is available. *Note: The air conditioner has been leaking a little water inside the room recently. I expect the pipe only needs cleaning and the air conditioner needs washing. It cost me 3400 riyals to buy it, and the sale is by offer.
