I need to replace my current home A/C. I have received a number of quotes and I have narrowed it down to a 13 SEER 4-ton Goodman and a 13 SEER 4-ton Payne (which I believe is made by Carrier). They both use 410-A (my old unit used Freon). Each installer has experience with replacing a Freon unit with a 410A unit. And I have checked the references on each installer (they were recommended by friends). The warranties are similar - 10 years including the compressor, although I was told I would have to do either an online registration or mail-in rebate to get the 10 years for the Payne. The total price for installing the Payne was just a couple of hundred dollars more. My question is whether the quality in the Payne model is worth paying a little more. From what I read, the installer is more important than the brand name.
