It's OK.
Best veg temps are 77-84, flower 74-79. If you are in flower now just try to get temps down further. Before I got control of my temp my rooms got to 90 much of the time, definitely a loss of yield in warmer temps but not a lot and no real change in potency, from experience. Everything just goes much smoother under 80.
You can do some simple things. Add a cool tube/air-cooled reflector with fan and ducting, light mover so you can use less lights therefore less heat, split grow room a/c, chiller with ice boxes, ect, ect. Just exhausting the room outside of the home does wonders.
