I have a long time client/friend who is considering Geo Thermal for some condos he's renovating. Since I've never dabbled, I will be referring him to a company experienced in GT, but the client wants me involved just to make sure his best interests are served.
That said, just a few elementary questions:
1. Regarding A/C...is this type of system practical in the hot, humid south?
2. My take on Geothermal is that it's operating principles are basically the same as HVAC but uses drilled holes into the earth for copper tubing to transfer the heat rather than air-cooled condensing coils (and also different equip., of course). Is this correct?
3. If number one is correct, do the same diagnostic methods apply? In example, would a temperature drop be a valid method of determining proper operation?
4. Can he expect the same cooling performance and humidity removal as with normal air-cooled HVAC?
