Having constant issues with a DX geothermal unit. Showed up today to find the oil in the site glass looking like this. To me it looks like water/glycol got into the refrigerant circuit. My thought is to test this by pressurizing the refrigerant circuit, if the nitrogen bleeds over to the glycol side, the glycol pressure will start to rise. My question is for anyone familiar with geos, what’s the next step to clean this up?
