split ac system

Ok i have a 3400 house with a 1400 basement. I have 2 - 2.5 ton unit in the basement and in the attice.
I am having problems cooling below 78 without running all the time. When i check the high side of the lineset it is coolish slightly warm and the low side is very cold. Is this normal or should the high side be hot?
I do have vents in the basement that are closed but the returns are open. Is this the problem that the system is drawling cold air from the basement and less from the 1st floor?

Let us know what the supply air temps and return air temps on each one are. Are the filters clean?

You have to let it run to cool it down. 3400sq with 1400sq basement ,dont know what your AC load is. But 5 ton should do it. All Filter clean and new every 30 to 90 days
