Unhappy Customer

AC under Warranty needed repairing. Sending service techs out that don't know what they are dealing with. Tech had to call in to figure out what was wrong. Tech said we should call the company who installed the unit to come back to fix it. Husband show him the Trane warranty registration stating Air Flex was the dealer and he said ok fine. I Had to call the office several times to confirm we were under warranty for parts only. It seems they were not interested in doing a warranty job. I had called Trane parts only to find out Air Flex gave them the wrong serial number(waste of 2+hours because no one followed up). I sent a copy of the warranty to Trane parts and they called Air Flex to tell them item was under warranty and parts can be picked up. I was doing most of the work for Air Flex in terms of admin work. The work was completed the next day and a mess and garbage was left behind for my husband to clean up.
