"HVAC Gurus,     I did an inspection yesterday where the client had a gas fired split-system with a closed loop Geothermal Water Furnace. It was an odd set-up because the gas furnace was in the attic and the Geothermal unit was in the basement.     Anyways, the water lines (closed loop) from the ground were icing up. To be honest, I'm not that familiar with these units. The owner swore that the tech said that it was normal.     However, it seemed odd to me. Should there be ice on these lines?     Thanks,     Kevin     Click to View     93.92 KB     Click to View     91.22 KB     Click to View     87.99 KB \n"
