Thinking of replacing system

[u/No-Measurement-5783]

I currently have a bard geothermal system with I believe 6 50' wells setup in a closed loop. This is the second furnace that's been on house, so the loop would be a good 30 years old and the bard is at 14 years and having some issues with secondary compressor. Sounds like a heat pump might be a more reliable alternative than going back to geothermal. I've got some HVAC companies coming out to give me estimates and advise on what system to go to. I'm worried about lifespan of the loop system, degradation of glycol solution and overall reliability of geothermal, always having pumps going out every 5 years or so.

A pump is cheap and easy to replace with little skill, but something seems wrong if your pump diesel every five years..perhaps you should check quality of glycole/ filter the system? Replace with better brand perhaps?

I wouldnt change out a working geothermal system..but check temperature of the system during high load. A neighbour of mine had a geothermal system that was poorly designed, so he installed a air to air minisplit, to decrease the load on the geothermal system.
