Relax.
What are the install costs, etc.?
For the price of the Split, you can get a few options that will serve you well, a 12k BTU window unit and this:

I have used a very similar unit in the link three times after hurricanes, easy plug into the generator or, now, the house circuits I power. Live saver. When it gets really hot, I run the portable unit at the barn.
I am all about options. Those two units and some fans and you are good to go.
BTW, a window unit can get a really nice non window install, like Glen's. I also have a a/c and heater unit at the Stable to keep the pipes from freezing in really cold weather. 22 years old and still cranking.
