Too hot!!! Need help

So here is what i have going, I have 4 1000w with reflector hoods in a sealed room with a 8in max fan sucking and a 6in can fan for the helper fan sucking cold air from my closet and being vented outside after going across the lights. I also have a 12000btu portable air conditioner inside the room.

The room stays any where from 85-93 even with the ac on all the time. Im running the lights 24hrs and now its getting hotter outside so im worried the its going to get even hotter in the room. Ive tried opening the door but it doesn't help and i cant run co2. Any ideas on a bigger ac unit or any other way to cool?? and this is my first time posting so criticism is welcome. Ive tryed taking pictures but the lights are to bright so no pics.

Dim it down to an 18/6 cycle. Your plants need and want sleep. They will veg still without flowering.

He will still end up with heat spikes. But its true that he should go on 18/6 regardless.
