I did several things to improve mine. I added the garage door insulation. Foam panels cut to the size of the garage panels. Helped some. Added radiant barrier to roof, helped some more. Added 8 inches of insulation over ceiling and two fans in the garage. Helped a lot. Garage now stays about 10 degrees below outside temp. Always cool in the AM and never climbs as high as outside. Next step would be to add a mini split. But all these steps should be done before adding a mini split and you actually gain quite a bit and at much less cost. My total cost for a big 3 car garage was about $1000 for all items. A mini split would be about $4000 as I would install it myself.
