A/C Rplacement/Tandem Alternatives
 

Here's my situation. I'm helping my family build out an office.

My parent's home has a cabana house connected to the main house. My parents want to convert it into an office for their business and it needs air conditioning.

The main house's a/c is too small to add more volume.... I'm looking for air conditioner alternatives to be used either in replacement or in tandem. They're currently thinking about installing a ductless system.


Any ideas on what's currently commercially available?


Area Stats:
10'x15' main area with 9' ceiling plus,
10'x4.5' closet-like space

That's about 1755 cubic feet of volume with a 10 foot long sliding glass wall facing east (poorly insulated - working on a solution for that) with a south wall that's shared with the rest of the house.


*The house is in South Florida with high humidity :(

Thanks Everyone :)

put office in cave? ;)

What about an A/C with an evaporative condenser?

Shouldn't take much for 200 square feet. If it were me I'd buy the smallest window unit I could find, build it in to the wall, then insulate + seal as best as possible.
