where to install the mini-split

[Vintage Veloce]

I'm considering where to mount the indoor wall unit for my upcoming 15k BTU Fujitsu Mini-Split.

I have a 525 sq ft garage that is 21' x 25'
The 16.5' garage door is on the 25' wall, 2 feet from the West end. So on the other side of the garage door , the East side, there is about 6 feet to the corner.

I usually park the vintage car on the West side of the door opening, and I use the East side of the opening for my motorcycles.

I use the side area for my workspace.

View media item 75159
You can see the primary work area is an aisle in front of my desk and bench.
I spend a good amount of time at that desk.

I've marked 3 spots on the wall where I could mount the mini split indoor unit. This would be mounted about 8" from the ceiling.

I originally thought "A" would be best, as that would be aimed right at my primary work area. But then someone mentioned the air blast can be annoying, and that maybe I should mount it offset a bit, at location "B".
The only other possibility is location "C", which doesn't seem to make sense to me as I seldom work over there.

Comments?

It looks like that model has louvers that you can aim, so in B (and perhaps in A) you should still be able to direct the air away from your desk and bench. Seems to me that B would be a good spot as it gives you the option to aim the air just about anywhere in the workspace.

Some mini-splits also have a powered louver that can be set to constantly swing from side-to-side to distribute the air more evenly.

I think A or B would be fine ......My garage is set up almost the same way & in the A position from 5 ft away you know its on but you dont feel too much air

Your 15 has 4 way air sweeps. It is also, assuming decent insulation, sized about right. I would swing the A position around to the wall the bench/desk are on. That way, you will not be in any strong air flow situations. The cooling mode will blow the air across the ceiling and it kinda settles onto you. The heat mode blows straight down and may be an issue. My Fuj. 15 in heat, which is what it is doing now, lands about 3' off the wall. If you go with the wireless option you can make it at your leisure prior to going to the garage and it will have caught up a bit.

Great feedback guys. Thanks.

You need to keep in mind that even in San Diego you're going to get a pretty good amount of condensate and you need to think about that when you decide where to place the indoor unit.

Where are you going to spend most of your time? Looking at your diagram, I would probably go with A

Probably go with A, in heating mode they blow downwards, thinking you'd have less obstacles to air flow in position A.

I was under the impression that the installer puts a whole through the wall behind the indoor unit, through to the outside, and it drains there.

And what does a "pretty good amount" mean? A cup a day? A quart?

Oh another question. The pipe from the indoor unit to the outdoor unit: we are considering running it through my attic about twenty feet to the West side of the building.
- Should I have any concerns about running that pressurized pipe in the attic? Leaks likely, etc?
- Should I have any concerns about placing the outdoor unit on the sunny side of the building? It really is the best place cosmetically, and noise wise...

(Note the primary use is the AC, I will use the heat, but in San Diego that isnt too big a deal.)

You can either use gravity to drain it or depending on the location (which is why I mentioned it) you would have to add a condensate pump

I am about 100 miles north of you and during the summer my Mini Split can fill up a 5 gallon bucket in about a day and a half. (I would never have thought it could produce so much water so I started using the bucket and then I use the water on our plants)
