Late last year I put in a ClimateMaster Tranquility Medium Temp W2W geo unit. It ran about 3 months and then one morning it faulted. Some diags later and tech support declares the TXV needs replacing. Repair guy gets parts from ClimateMaster and puts them in. 1 day later unit stops working with the same fault. Some diags later and once again its the TXV. Repair guy gets parts from ClimateMaster and puts them in. Everything is running right now but for how long. The repair guy said he has seen this before with the same unit so it made me wonder it this is just the beginning.... So my question is am I just extra special and got a lemon or does ClimateMaster have a serious quality issue with there W2W units????
