I'm just a homeowner and I'm here trying to increase my knowledge

[wensteph]

We're in Savannah and beginning the process of building new home. So early in the process we haven't contacted an architect or narrowed down a builder, but we want to go high efficiency. Considering a sealed attic and I'm here hoping to gain some knowledge to help in selecting a HVAC installer.

This is a very interesting and informative website. Thanks to all who contribute.

You have some challenges ahead. Include fresh make-up air ventilation as part of your package. Also you will need a whole house dehumidifier to provide <50%RH during low/no cooling load conditions. Ask about the Ultra-Aire system which has a fresh air ventilation/filtering option which is well suited for the that humid green grass climates.
Keep us posted on the any upcomming questions.
There are many well qualified a/c contractors in the area.
