12,000 btu per ton. The roof load with no insulation in a climate like yours? The 5K and 8K won't keep up. I run a 18,000 btu portable, mentioned above, in my garage and it works hard to keep up in a fully insulated garage when I have guests over.
BUT! I'm just a guy with a background in HVAC... so I could be wrong.

No doubt that ceiling insulation would be ideal - but some factors in my situation that might be different than what's typical.
Roof is white in color from silicon treatment I gave it two years ago. The layer of silicon is over two-layered peel and stick which is over plywood. The white silicon has made a significant difference - as evidenced from my remote temp. sensor
Roof has shade all afternoon and some in the mornings from surrounding palm trees.
Also, the garage stays shut up most of the time and I don't plan on staying inside there so just trying to take the edge off a bit.
The garage also faces North so that helps.
Thanks for your input - it's greatly appreciated....
