 However you do it you need to be really sure that you are not getting moisture down into the fan and electronics. I doesn't take long to start having problems if that happens.  I have a customer who says he is going to try this, I am interested in how it works.

thats what i thought, water problem but this guy swears it works and he does not have a moisture problem, as far as the pipe a friend said i will need about 1200 feet,  and pex is cheep , going to dig about 7 to 8 feet down and do a loop design, i went on line for geothermal and it shows a vast amount of information for underground and water installs. i am going up to see his unit this summer and will report.

You are going to try pumping water through 1200' of pex? What size are you going to use? 1" won't be much volume.

Have you looked at the head loss on 1200' of 1" pex? You won't have much water moving.

It doesn't matter what kind of pump, it will be slow. I thought the fan ran faster for AC.
If you are going to stay with 1" pex and if possible, I would split it into 2 600' runs and put them in parallel.

How much are you paying for the pex? 1200' won't be that cheap. How much does it cost to run your AC?
