We just started a renovation/addition on our 1960s home in the Washington, DC metro region. We are considering installing a geothermal system (e.g., Climate Master Tranquility 27 unit/s). I am looking to get up to speed so I can ask intelligent questions as we consider various HVAC options and costs - particularly related to this type of geothermal system. As we go to bid, would you please help me know what I should be looking for from each bidder/installer?
I want to get this right, and have time to do a lot of research, etc.
Thanks in advance!
