i am a carrier dealer in houston and have installed the infinity systems . when you match the infinity controller to a variable speed furnace /blower with a 2 speed condensing unit you have the most aggressive humidity control of any factory system made.note i said factory ,there are hybrids that perform aswell but the infinity rocks. one problem carriers evap coils are still made in mexico , this has been an issue with refrigerant leaks . that is the only negative .
one huge positive is the fact that the installing contractor will have to size the ducts correctly otherwise the infinity controller will show high static pressure and low airflow in the service section of the stat ,pretty cool.
