David in Texas

David called to ask about how to cool his large ranch home with bedrooms at both ends of the long structure. He first thought about putting in two systems – one at each end. After talking about how air will move from any part of the house to any other part as long as the doors are open, he decided to put in one 36 inch system. Since he is in cold country he also decided to really insulate the ceiling openings with the Invisco R60 dual dampers. I introduced him to VentMasters in Texas for installation. He called to say “The system really does move air through the whole house!”
