Ellen, you hijacked this thread. You are also brand bashing, possibly unfairly. Furthermore, you are not paying for advice here, nor are we receiving compensation.
Were this your thread, it still would not be for your sole benefit. The point is to help the people posting AND the people reading, which sometimes means calling out discrepancies in what the people posting have written. This may or may not help you on your specific situation, but helping 10 to 10,000 others is a greater good.
I don't know how oversizing impacts operation of a chiller, but in more common residential equipment it causes all kinds of trouble with equipment breaking down prematurely. That point needs to be made for you and the average Joe who might stumble across this thread.
I'm kinda surprised your rater didn't catch it. Maybe put HIM on the spot.
