I've got a guy coming out tomorrow morning to discuss the viability of going geo, using the north pond as the heat sink. I already understand that one of his first steps would be to measure/evaluate my home in order to properly size the system.
What else should I expect on this first meeting? Any suggestions would help, as I've no real idea how this all works...shooting blind here.
On the bright side, I found him on the Iowa IGSHPA (Ia Ground Source Heat Pump Association) database. Hopefully, that means he's good...don't know, though.
Ask for references, then call those people and if possible go and see their system.
Some of the local utilities also sell and install geo and/or might know an installer with good reputation and track record.
