I purchased a home that touted an open loop (well to different well) geothermal setup using a Bard system. The discharge well has soil missing around the well head. I had assumed this was due to erosion. When I was contemplating purchasing the property, I had mentally wrote off the geothermal system and turned it off as soon as I got the keys to the property. Now I am contemplating what HVAC system / setup to replace it with. Before throwing out the open loop geothermal setup, I would like to investigate the discharge well erosion (assuming it is erosion) to see if it can be fixed, but I don't know where to begin or what key words / phrases to convey to potential companies to try to find someone qualified. There doesn't seem to be many companies that offer open loop geothermal systems in my area, at least that is advertised on their websites. I would like to be know a little of what I'm talking about, before I start making phone calls. As far as service calls go, I've had a few experiences with other issues (not HVAC related) where whatever company I was talking with at the time reassured me they deal with that sort of problem, but end up using it as a sales lead to rip out and replace. The seller of this property could not or would not tell me who did the installation, but they had a local HVAC company that happens to sell Bard geothermal equipment do a maintenance call, as reassurance to potential buyers that the system was operating as designed. There are three well heads on the lot, and one appears to be abandoned. None of the well drilling logs were registered with the state. Based on the upkeep of the house and what I know about the seller, I suspect they purchased the Bard equipment and installed it themselves. Should I call a HVAC company, or a well drilling company? What service am I asking to be performed? What about the discharge well or HVAC system should they be looking at? Thanks in advance.
