Looking for some advice from an HVAC person on the following situation:
My fish room is located in my garage. The closest exterior wall is approximately 40" away. I had planned on putting a dual hose portable A/C on a shelf I built specifically for this reason that sits about 35" from the ceiling and is on the wall closest to the exterior wall. After speaking with the manufacturer of the unit I was interested in....they advised me that the unit should be on the floor, (not on a shelf), and the unit should be a minimum of 12" from any wall. I had planed on butting the unit as close to the wall as possible. Of course now I have to switch plans..... Before planning on the portable I was going to put an A/C through one of the walls to empty into the garage but that plan got squashed since I was told that the garage gets too hot and the in wall unit would also need to be vented outside. So that's 2 plans out the window (which I don't have LOL). I can't sit a portable unit on the floor because it too would then need to be vented into the garage or I would need 10 feet of 4" hoses to vent it out and that wouldn't be efficient. I'm looking for some help here. If I place an in wall A/C unit through the wall closest to the exterior wall does anybody know if I can use aluminum duct work for the 40" to exhaust it outside? Will this work and will it work efficiently? The last possibility would be to use a split unit...with a condensor outside....or a chiller....but I was hoping to solve this problem with a cheaper solution. I do have a large A/C in my Living Room which cools the whole first floor but I was looking to supplement this with a unit in the fish room first. Solutions????

Just put some 2x4s on the perimeter of your shelf to make it stay. The 12" minimum is probably for air flow and I am sure you can reduce that a little. Its probably because it gets the air intake from the back. A portable will be your cheapest and most feasible solution, followed by a split unit.
