unvented hoods w/ AC

Im trying to run my blockbuster hoods without glass in my 8x10 room.
Ive tried with 600W up to 2,800W in the room but I cant keep the canopy temps in check.
The more load I put on the AC the hotter it gets.
Its a professionally installed 24,000 btu unit. There are no error codes shown on the diagnostic test.
Do I have to air cool the hoods or is my AC fucked?
It seems to blow cold air. When I turn off all the lights I can get the room down below 70

Is the room well insulated? If not that will make a difference. But air cooling those hoods should help as long as the ducting is pulled and pushed outside the grow room. But honestly, a 28000 btu unit should cool that room with ease.
 
The room is insulated and the garage its in is around 77F. Theres also reflectix on the inside. Its sealed up as tight as can be. Even the door has weather stripping and a gasket.
I do have my veg tent next to it sucking some air out of the garage. Theres an intake vent connected to the outside wall so it doesnt suck much air out, if any. My Co2 isnt leaking and even with the veg tent shut down I have the same temps.

I would get a fan for your hood, I run a 6inch hydrofarm fan. Keeps my 1000watt hps cool to the touch & if you can run your lights @ night. In my opinion its more efficient to cool your lights then the whole room & you wont need to blast the AC. You can also keep the light closer if you go that route. You'd have to cut a hole through the wall so you can set the fan outside of the room, so it doesn't suck your co2 out. Good luck.
 
If I try to air cool my lights and use co2 I will still need an AC unless I want to suck all the co2 out of the room.
Im not sealing my room to use co2, Im using co2 because my room is sealed...
Might work your way a few months out of the year with 1 light, but thats not gonna cut it with 4-5 lights year round.
I dont want to deal with duct leaks/repairs and dirty glass. I just cleaned my veg glass twice this week and its still all dirty.
Ill get rid of the hoods and go vert before I air cool again lol
