Have a Carrier 4 ton geotherm 2 speed , Isolated refrigeration circuits variable speed ICm fan motor closed loop dual pump package model # 50ybvo48. I have had 3 compressor failures in barely 5 yrs . I have searched all over and I can not find any information regarding other people having these failures.I have had a leak in the ground loop and it had to be filled at least 1 time a yr sometimes twice, and contractor finally admitted it leaked and fixed it this fall when he installed 2nd new compressor. that compressor was in 5 months and ran maybe 3 months before it failed. The first compressor failed within the first 45 days. Both circuits have had 1 compressor replacement so it is not common to 1 circuit. They are going to replace the unit but they say that the engineer who looked at it after 2nd compressor was installed and nobody else knows why it failed. I am really concerned that it was not units fault but was a bad installation and that the same person is putting the new one in without any changes.
Am I just a worry wart or does any think that the ductwork or the loop could cause these kind of problems. There is a lot more information I can provide , I have had other problems too and it always seemed to happen at same time of year during late Januaury Thanks.
Sorry about the long post Thanks
