How can I hook-up my furnace to existing HVAC supply ductwork?

td2320 asked:


My existing HVAC system has insulated ductboard and I need to know what type of connection pipe should be used to connect my furnace into the ductboard? Part 2: Can you use crimped galvanized pipe without taking apart the ductboard?

    Sleeve the new metal plenum into the existing ductboard and tape with foil (metal) tape.

    I would have to look at it! There are alot of variables. You are asking how to put together a puzzle without someone seeing the picture.
    But it can be done, no problem. Its just i cant tell you exactly what all parts you will need.
