I recently had to call a repair man for a warranty claim for my air conditioning unit. So I called the company who installed the system. The tech came out looked at it and told me it was a bad capacitor. He told me he didn't have one at the time but had one that would work for the time being and would be back to put it on. He said nothing about cost or there ever being a bill associated with the call and that the capasitor was under warranty. A few weeks later i receive a bill from the company for $89! i called and asked why it was so much. i was told that it was the labor cost for the tech call. I informed the person that I was never told there was going to be any bill associatedd with the call ,and however i did understand the need for a charge i felt that it was way too much since it only took the tech 5 min to figure out what it was. isnt there any law that protects the customer from just a huge bill at the end.
