Thanks Doax!
AC,
Yeah you just pointed out my biggest concern at the very beginning. The show WILL go on.
Oh the ground here is AMAZING! Plus in about 40-50 feet from a large 2 acre pond. So hitting water will ALWAYS happen. I already have 500 feet for HDPE 3/4 poly pipe in the pond for a geothermal loop idea I was already working on to heat my greenhouse (aquaponics) in the winter.
I have about 10 hours of reading ahead of me. I did find some good sites though.

And another forum mentioned using a oil separator, i guess like this one
1 3 8" HVAC Oil Separator 559011 | eBay
Looks from what I can tell the line coming from the HX coil is larger on the way down and smaller on the way up. So I'm thinking 3/8 down, 5/16 up. I will try one 30 foot bore hole and if it doesn't work I'll just drill another hole.
Are there any people with experience with DX installs on this site?
