During an ATS install and during power outage we may have damaged the control transformer for ac. The customer called theirAC people and they determined it was the transformer. The customer had home warranty so customer Home warranty fixed the issue only charging customer $60 of the $560 in repairs leaving $0 for customer to pay. Customer wants $560. This may or may not have been our fault but how is that determined? Second why do.we own customer money and not the warranty service. This ever happened to anyone and how was it resolved
Please correct anything I have wrong but sounds like shortly after you done your ATS install, the AC system stopped working.
Customer called a HVAC company and they determined the control transformer is bad. HVAC repaired it and had a repair of $560?
Customer's home warranty company paid the HVAC company though I'm not clear on the mentioned $60 as to whether warranty covered all but 60 or if they paid all the bill as you also mentioned "leaving $0 for customer to pay".
What I don't like about this if I have things right is if the warranty company paid for the repair bill, then why is customer asking you for full amount of the repair bill. If anything they should only be asking for the $60 portion if they only paid that, and the warranty company should be after you for the rest if they think it is your fault it failed.
Regardless who is asking for payment, I be wanting to be able to examine the defective transformer or at least have some other party investigate it and determine what may have caused the failure. If they already got rid of the evidence I wouldn't be willing to simply pay up. The fishy thing here is say if you somehow applied improper voltage and that caused it to fail, chances are there would have been other items that failed from improper voltage as well.
I think this customer looking for a free lunch, don't give in too easy. Let them take you to court if they willing to go that far. Hopefully they end up spending more than they get from you out of this case. I still say the most you owe them is $60 if it can even be proven you cause the failure. The warranty company is who should be pursuing anything more than that from you since they paid the bill.
