Anybody have any PERSONAL EXPERIENCE with geothermal heating/cooling?

[Dover]

I've read some info but would like to hear from anyone with a residential unit. Some local schools have installed this system for their cooling/heating needs (though I'm told in these southern climes, some will use traditional cooling systems to supplement it). I was a little shocked at all the hole drilling that had to be done for these schools - at least 1000 wells - which is pretty disturbing.

At any rate, I'm only interested in experience with residential units because I am looking for alternatives as my current traditional heating/cooling system ages and needs replacement.

I'm curious about the comfort levels, and any other issues that might have come up with its use/maintenance.

Thanks.

BTW - Here's one article about this system:
