Can open-web floor truss space be used instead of ductwork for heating/cooling?
I have a already built 3-story 3,800 s.f. colonial Garrison outside of Boston, MA. When we built the home in the late '80s I figured to save money on duct work by not putting in whole house AC. I might have saved then, but I'm going to have to pay now that we are putting in a new HVAC system to replace the oil baseboard heat and window AC.
The house has open-web floor trusses and am wondering if it is even possible to use the open spaces between floors for air distribution? The perimeter of all the trusses have been sealed with 3" closed cell foam, 1" foam board on the outside, and a house wrap, so the space between the floors is tight.
My knowledge of HVAC systems does not go far beyond cool air falls and hot air rises. Just hoping that floor and ceiling vents combined with open web floor trusses could offset some of the $12K that I just got quoted for ductwork.
