Have a two year old Carrier with a 10 year parts and labor warranty. The King valve assembly leaked out all the freon. the dealer found the leak and ordered the parts from Carrier on Wednesday June 2, 2010 and today is Monday June 7, 2010 and still no parts. I wonder if carrier has ever heard of FEDEX? I called Carrier on Friday June 4, 2010 @ 11:00AM and spoke to a "senior customer specialist" who promised to get back to me before 5PM on Friday. At this point I volunteered to drive to Orlando to get the part. On Monday I spoke to the same rep who told me that the part "was not ordered soon enough to make the truck". I again asked about FEDEX and was greeted with stone cold silence, she had no answer.
I suggest that you purchase some other brand an ask if they know who FEDEX is.
