Too general of a statement. It isn't clear that a builder grade Carrier system will be more reliable than the high-end system from another brand. BTW, the Carrier Infinity failures were never really an issue. They were all covered under warranty and parts were always available the next day. With their zoning system, the temperatures across the house were always even. The 2 piston Bristol compressor was eventually replaced with a Copeland scroll and I suspect that was an improvement although the 66% or 100% compressor speed was not as ideal as the 50% or 100% speed of the Bristol.

Here in the Villages most Carrier single stage units are working 10+ years with little to no failures and that's a lot of systems. There are so many variables that can affect how long your system lasts but the point was the premium tier brands, generally should last the longest and be the most trouble free compared to the cheaper lower tier brands since the tend to use cheaper components that aren't designed to last as long and that's why there are less expensive.
When the Carrier Infinity systems first came out, like yours, they did have a lot of issues, but over time the system has changed dramatically for the better and there are much less issues. It's a fairly robust system now.
