Cost to buy and install refrigerated cooling?

[Manuel A.]

Just finishing up my rehab estimate and I need one more key piece of info, how much to buy and instal a refrigerated air system. My current rehab price is right at $23,550 but I need this last number. The neighbor said the house had refrigerated air before it hit the market, so I figure that's what I'd put into it if I got it. Otherwise swap cooling is what I'd put. It's what I grew up with, and currently live with :D

I went to Lowes and didn't find anything.

So... any idea how much?
