Alright, Bryant is Carrier in case you didn't know. Good Equipment.
If your duct is insulated and properly sealed along with your home being normally well insulated it will save you in the neighborhood of 20-30% as mentioned in that one article.
You should notice more air comfort through dehumidification but it will not be truly "adjustable" without a humidistat. When I installed this brand of systems the Infinity thermostat was the bomb. It would do amazing things that I am sure you don't really want to hear about.
You should notice the system being overall quieter because the fan will ramp up and down as the system cycles.
The motors are half again to twice the price but they should last 5-10 years without an issue. They would last at least that long back when I was putting these things in and they have improved the technology since then I am sure. When our rep came out to visit as well as the classes we took on these units Carriers people always told us that the motor should last 2-5 years past the warranty.
