I hope you had better luck than I did. A few years ago a board went out on the blower unit, they came out to inspect, told me it would be $500 for the board plus another $80 to come back out and install it, all this plus the $80 I just paid. I said do it, they ordered the board. The board was supposed to be in the next day, when I didn't get a call back for three days, because they were waiting on the board to be delivered, I started researching. I found the exact same board on Amazon for $100 with next day deliver through prime. I called to ask what was so special about their board... crickets.
