I bought the AC new from the appliance store, split, Zamil - Zagzoog brand, 18 units. It's excellent. I installed it in my living room and it turned out the room is too big for 18 units, I need 24 units. I haven't even had anyone visit my house yet, I just turned it on. I bought it for 1750 riyals. Whoever is serious and has a room suitable for 18 units, this is very suitable for them. God is my witness to what I say.
