Holy shxt... What a disaster. If anyone is looking to get into a condo / apartment with geothermal heating / cooling, know that the mere act of finding someone to service the thing is a major PITA.
None of the indie heating / furnace servicing people that I called do geothermal. Not everyone that Google turned up has good reviews. Some don't call you back. Others don't do geothermal.
Schmidt Bros Mechanical seems to have a few good reviews, but unfortunately, Tri-Cities is outside of their service area.
By the time I found
Moore & Russell, I didn't even bother asking about rates. At that point, I was pretty much ready to beg them to come look at the darn thing at any price.
We'll see how this goes. Gosh...
