right now my plan is to screw around with a couple $50 window units I have, been talking with a good friend who does HVAC and I am planning on seperating the components and building a few little boxes and he will extend the metal tubes,vacumn and refill them...should work good.
He says a 5000BTU seperated like we are thinking will cool better than an all in one 10000BTU roof unit.
He says they are not very effecient since they are stuck out in the sun etc.
We'll see...it's cheaper than a mini split unit and will works the same
Ducting will be a challenge...but hell what isn't
