exhaust fan with air conditioner?

I just put in an air conditioner for my grow room but am not sure if I should keep the exhaust fan running or just get rid of the ac. Wouldn't the exhaust just suck out all of the cold air? Thanks for your help.

Also I am in my last couple weeks of flowering so I know they need all the fresh air they can get.

I live in the desert and my outdoor flower room has an a/c unit which doesn't work for shit unless I forcibly exhaust the heat. (vent is tword the top of the shed, fan forced) Heat rises, so little worry of venting-out the cooler air.
Easily a 10-20 degree difference between vent open, and vent closed. Also...after watering, the humidity skyrockets without the exhaust.
