My solution was to insulate the garage attic and garage doors then add a mini split. On hot days the outside temp can be 90 degrees plus and my garage is 80 degrees inside with low humidity just running the mini split on dehumidify. You can always set it to A/C if you want it even cooler.

That is true during the heat and sun of mid-day, as the sun moves away from the garage door later in the day the attic fan pulls in the cooler air through the bottom of the door via installed vents and continues doing so well into the night. I've had one for the last 7 years along with fiberglass door insulation, it is set so that it kicks on after it get's to a certain temperature which usually is around 4:00 PM and then it starts feeling much better in the garage without opening the door and letting in mosquitoes, etc. I definitely got my money's worth out of it. During the day if I have to work out there I do have a fan that I can move around to circulate the air.
