1st post here, Found this site just recently, looks to be many interesting projects to peruse.

However, did a search on GSHP, and the screen came up with

"Step 1: Find a Contractor
Because you should not attempt to do it yourself, you need to find a qualified contractor or installer to install your geothermal heat pump."

Why 'should not attempt' blather in a DIY site??? Simply add revenue?

Did own GSHP with no problem, looking for others who have done the same and any unique techniques others may have idscovered.
BTW, own diy gshp has a cop of 5.6, lower than perfect but better than anything in the ari rating sheet that ive found.
Know i must have missed a few things, as theory for my conditions says I should be able to get to over 6.

I'm not sure just what your question might be but the direction of finding a qualified contractor is because a person must have a license issued by the US Environmental Protection Agency before they can work on any closed refrigeration system. Violation of this requirement can lead to fines as high as $25,000 and also imprisonment.

Furthermore, it takes some pretty specialized equipment (and training for that equipment) to service any kind of refrigeration systems and that equipment is not inexpensive and is rarely applicable to other DIY type projects. Bottom line is that just getting certified and purchasing the necessary equipment will be far more expensive than calling for a qualified installer or serviceperson.

DIY is supposed to save money, not find more ways for the homeowner to spend it.
