We ordered some parts for the evaporator fan assembly from our local dealer Duncan supply. They did a great job providing us AS data including a visual breakdown and detailed parts list. With what we asked for they recommended we needed reference numbers 4 thru 9. In the quantity needed column it clearly shows we needed one of each of the 6 parts listed. Part number BLT00217 clearly shows that part number referencing one bolt. So we ordered one of each of the 6 parts required. When we received our invoice from Duncan Supply it listed one of each of the parts received. We find however that part number BLT00217 that clearly shows quantity of one on the factory parts list and Duncan invoice is actually a box of 25 bolts. So I am charged $21.67 for what should have been one bolt. I have discussed this with Duncan and it is not their fault. They have contacted their AS factory parts contacts and are told AS won't take the box of 25 back and too damn bad for me the customer. This isn't at all the customer service I expect from a company that I have spent tens of thousands of dollars with over 40 years. User's recommendation: Consider another manufacturer as you sure can't get customer service from American Standard.
