Building a new home in a medium/moderate climate and wondering if the extra cost of enveloping ducting in a furred down space is worth the extra cost over insulated ducting in my attic? Any help/thoughts on this is appreciated. ALSO.. What is the most effecient type of HVAC unit for good heating and cooling? PAUL
What's the design say?
What's your utility rates?
Quite frankly Cowboy- you will save a bundle on energy by using the highest R- in insulation you can, deeply burying the ducts in the insulation, and enjoy the benefits of energy credits during the design phase. Use a TXV and ask for Title 24 duct inspection as well.[You can exchange energy use credits for more glass area or higher performance like sky lights, lighting and such.]
Check with your architect and Title 24 Energy pro.
