Portable A/C for windowless garage

[Anoutkast29]

My garage is 19x24 and I recently purchased a portable a/c unit with the hose attached. Any suggestions on how to go about putting the perfect sized hole in a concrete wall? I've already read several threads, and see instances where they work. But I need some pics or a step by step process in order to get it approved by my wife (she's worse than any HOA). My garage has r-16 insulation in the ceiling. I also will be adding some kind of insulation on the door. Thanks in advance.

How big of a hole do you need to make?

I have the same setup with a portable a/c unit, with dual hoses.

I drew two circles with pencil (I think it was either 4 or 5 inch hose size). Then used an air hammer with chisel attachment to chisel the hole out the best I could. The holes are not perfect, more of a rough in type of hole. But then they make plastic fittings that fasten to the wall that make it look clean. Kind of like if you rough cut a rectangle into drywall for a light switch, but then when you install the plastic light switch cover it makes it look clean and nice.

The plastic fittings I had to buy off the internet, because no home improvement store sells them because they are kind of a specialty item.

If you look at the last item at the bottom of the picture. That is what I used. Rough cut the hole in the wall, then you use four small Tapcon concrete screws to fasten it. Then it has a nice clean look, and even a cover flap when not in use. Then your hose goes into that second to last item at the bottom, that piece then perfectly fits into the hole of the last item you installed.

Then I did this to insulate the door. There are tons of write ups on the internet for this. This is also very cheap to do, because all you need are a couple 4x6 sheets of the panels, a roll of duct tape, and maybe a couple tubes of either caulk or tough-stuff foam spray. I think it cost me less than about 40 bucks to do a double garage door. All the supplies are available at your home improvement store. They also sell a "Pink Panther" garage door kit where they sell the insulation, but that will cost probably double what the home made silver job costs.

I'm in a very hot climate, and this immediately cut the temperature down by 10 degrees in the garage after I installed it.
