Geothermal Heat Pump with refrigerant Leak
A GHP is leaking refrigerant. A HVAC tech recharged the system and included a dye pack to look for the leak. He intended to leave it running for 30 days. However the refrigerant had leaked out in one week. HVAC tech spent 4 hours trying to find the dye and could not. Then pressurised the coax, compressor, and condenser coil but claims they all held pressure. His recommendation, new system!
First anyone have any comments or suggestions.
Second, is it possible that the refrigerent leaked via the coax into the horizontal water loop?
