My daughter and son in law have a Trane Unit in their home. It is heat pump with electric furnace back-up. The unit is about 4 years old. June 2017 it started acting up so they called a Trane/American Standard HVAC company to look at it. They said it was a bad TXV valve for cooling. They had it replaced and all was well...other than Trane wouldn't cover it under warranty because they didn't call the original installer (which they didn't know who it was). 1 year later almost to the date the unit failed again....they called HVAC company back out and it was a bad compressor, because TXV needed for heat failed? They replaced this and had it running fine...until a few days ago. I guess they noticed heat pump was making real loud noise and back-up heat was all that was working. They called the company back who installed compressor and they said compressor was bad again. Daughter then called Trane and Trane sent out the original installer of the unit who said unit was way overcharged! So then they called back the installers of the compressor, they came out today and confirmed unit was overcharged, but said they didn't know why it wouldn't keep running. Heat pump kicks on, runs about 20 minutes then stops working. At this point everyone is pointing fingers and nothing is getting resolved. Trane says warranty is no good because they used a service company other than original installer....even though they are a Trane dealer. Trane says the HVAC company could have transferred warranty for $100...but they never told customers that.
Bottom line is this unit isnt even 5 years old, 2 compressors, 2 TXV valves(?), about 10 days of missed work, months of $600-700 electric bills and no one owning up to what the hell is wrong with it. I know this is a confusing mess....but what is your guys thoughts? Will an overcharged unit cause major failures? When the first TXV valve was replaced would unit have been recharged?
Thanks!
