A system diagnostic is for the purpose of identifying weak points, determining the cause of a problem. What is at fault!

No matter how long it takes to figure out the issue there is only one fee. Once that issue is found the technician will provide the customer with a quote for a repair. The customer has a choice to repair it or not and the quote will be good for 20 days. There is no obligation to pay any repair bill unless the customer wants to get it fixed. Once the repair has been done and system back in working order.
