Portable dual hose air conditioner

[cmueller57]

I currently have a single hose portable ac unit, works OK, if I'm very nearby, just the cooler air helps, but has little effect on lowering garage temp, I live in southwest Florida. My garage door is already insulated, and that helped pretty good, considering the low cost and effort. The morning sun made the door extremely hot. Ceiling in not insulated. My garage walls are concrete block, my HOA would never allow a window AC.
I'm wondering if a dual hose portable AC would be worth it, as well as insulating the garage ceiling? Anyone go from a single hose portable to a dual hose?
I know a mini split would be the best way.

Dual hose will help tremendously. Insulating the ceiling will help. Installing a mini split and the insulation will be best.

A dual hose will be better. I have never understood the single hose units they are taking indoor air, cooling the condenser coil and blowing it outside. Then more outdoor air has to come inside from somewhere to replace the indoor air that was vented out through the AC unit. It doesn't make one bit of sense to me. Probably cooling 12,000 BTU, then pulling in another 6,000 BTU of warm humid air.

Insulation is the answer, it is just about always the answer! Insulate the ceiling, and I bet if you furred out the walls and added even some 1" foam and sheet rock you would see a great difference.
