A service technician from my company diagnosed a leaking evaporator coil on a geothermal heat pump system a few days ago. Coil was under warranty, we ordered a new one and he charged the system with over 5lbs of R-410A to hopefully get them by until coil arrives and replacement can be made. The customer calls back today, says its not working again. He just called me he arrived and the system is low. customer says it only worked for not even two days. This time its worse he can actually hear the leak and see the oil around the problem spot. He was charging it again, (to get them by for a very short period). I told him he shouldn't even charge it up, and this is the last time until we can make replacement, aside from wasting money and time, I am apologetic for the customer don't get me wrong. But, are there any dangers to the living bodies or any thing in the home with a loss of this amount in such a short time being delivered into the airstream of the living space? I believe they keep fan in ON mode.
