Mini split for 2 garages?

[notabmw1]

So I am completing my detached pole barn that is insulated and drywalled. I was looking at putting a mini split in there, as well as my old attached garage I will be converting to a "play room". So one garage is about 700 sq ft, and the other about 500 sq ft. I was wondering would it be possible to run one outdoor unit, and have 2 zones (2 indoor units, one for each garage)? It seems feasible to me, however, how would I get the refrigerant lines over to the detached garage in the back yard. Could I dig a trench and bury the lines? Would I need to put them in some form of pvc, etc? Or would I be better off just running 2 separate systems? I know some have some line distance requirements, mine seems to be cutting it close at a distance of roughly 50-60ft away from where the outdoor unit would be... Thoughts?

Subscribing to this thread as I'm kinda in the same situation.

For this unit, it looks like 35' is the max distance... http://www.alpinehomeair.com/viewproduct.cfm?productID=453069549

Ironically enough I actually bookmarked that one yesterday. I'm no expert, but figured if I only had to run 1 setup for both unconditioned spaces (Existing Home uses gas baseboard heat with window units, and I am not looking at upgrading house, just adding to these 2 spaces). From the tech sheets, looks totally doable, I just don't know the implications of running it underground, if any?

I agree with you. I would run conduit if you can, but remember conduit corners are an issue with the lines.

I think in this situation you would be better off with separate units.
