well, I use a lot of carrier units. last year i installed a large job. all units came form Mexico. had just a few problems.. There are a few things i don like about the new carriers and it pisses me off... Unless you get the more expensive ones.. all the panels are screwed on using these plastic inserts to screw too... during install, Electricians, mechanical guys and balance guys stripped almost half of the the plastic holders...now i have to worry about covers flying off. So now i'm running around zip screwing them.
The other thing i noticed, Carrier is using carbon molded pulleys on the fan not motor just the fan..So far no issues..Just thought that was interesting. The bottom line, on the commercial grade or budget grade they really cheapened the quality anywhere they could. Also, i needed a factory part, and it took forever to get...
I starting to look at Trane more...not sure how much better they are in quality ..looks like everyone is cutting where they can.
OK that was commercial units...The same goes for Residential, but i will say, Carrier and Trane make different grades each cost a bit more. when pricing out the job ask your rep what the differences are..Sometimes he may not know..But sometimes its like getting a plastic bushing instead of a brass one..or heaver gauge metal, sound deadening etc...
The one that is sized right, installed correctly and properly maintained.
this answer reminds me of the movie forrest gump where his sergeant asks him what his purpose in the military is.
now my company is authorized Bryant and Trane dealers. I install and work on a lot of carrier/Bryant systems along with Tranes. I like both about equally. They are both high quality reliable systems as long as they are installed correctly as jmsmars1 said.

Depends on a couple different factors not just the brand. How it's installed, how it's matched up, efficiency, and how it's serviced. There's other brands out there that are less expensive and will run just as good.
