I am in the process of building a new home and wondered if the cost of
enveloping my ducting by furring down in hallways/etc. is worth the extra
expense in energy savings over just using standard or insulated ducting in
my attic space? Home not in extreme temperature area, 100 degree is very hot
and teens is very cold.
Any help in this as well as the best and most effecient type HVAC unit/s
