HVAC unit in attic
The contractor installed an HVAC air handler in our attic space. The round flexible ducts, hot/cool air supply, lay on the insulation or on the 2"x4" roof joists.. Our local building code requires R40 in the attic space.
The ducts are not well insulated and I believe they have taken away from the R40 requirement. By how much, I could not guess.
The Air Handler has minimal insulation on the interior, 11/2" at best. Where the electrical heating coils are located, there appears to be zero insulation.
My question; is there a correct way to insulate the Air Handler with the assumption the heat loss through the metal skin of the Air Handler could be reduced? Likewise for the supply ducts.
