“My complaint is regarding overcharge for service to replace the expansion tank on my water heater. A $95 diagnostic fee was charged which I had agreed to. But then the bill came for replacement of the tank in the amount of $384. After paying the full bill ($479 + tax) I checked the market value of the identical expansion tank that was replaced. The tank retail price is around $65. When I asked the Williams rep over the phone for a breakdown of the cost of the repair in terms of parts and labor, he refused to give me a price breakdown and said just that it was one price for the repair. Needless to say I will never call on Williams Mechanical for repair service again.”
