I am the original owner of a 17 yr old home. I want to replace the original Ruud a/c unit and inside furnace/blower. I live in NW Georgia so super-high efficiency is not my top priority. Of the 3 brands I mention in the subject line, I would like to know which is the most dependable. I've talked to a trusted, veteran HVAC tech that services many brands and he mentioned not to choose Carrier because they aren't made as well as they used to be due to using cheaper materials, etc. The co. he works for only deals with commercial accounts so he has no vested interest in steering me away from any particular brand.
I turn to this forum to get a much broader view and opinion. Your help is appreciated.
