All right I have a Reem roof top unit that is undersized. The building used to be a c- store now its a Dominos and I believe we are genarating more heat now in the building. So this is a lame way of fixing it but what I did is set a sprinkler on the condesor coil to help it reject the heat. It seems to be working but now I'm trying to see if there is a better way to do this cause I am worried about scale building up on the coil. I have herd of a system that works like a swamp cooler for the condensor but not have any luck. Customer is renting thew building and does not want to really put a new unit on the roof. or add one. just cause of expense.
