I'd venture to guess that most houses in the Southern US aren't very comfortable. They are either too cold or too hot! The missing component in HVAC is Dehumidification. Ultra-Aire has a new Dehum that I think is a game changer.

There are 4 things every house must control (in order of importance). 1. Water 2. Air 3. Vapor 4. Thermal Codes have only started to address air control and I think many builders in the US are behind in this area.
