Hi,
Suppose i am unable to get one duct run from the heating unit to where the vent will be and i am forced to use two ducts instead. What is the best way to connect these ducts? is using tape sufficient or are there specialized connections for these types of situations?
Also, currently, the duct that i see used are the black plastic ones, very thin it seems. Is insulation needed on these ducts?
Now i am not necessarily asking this so that i can do it myself, i am asking to see if it was done correctly by someone else.
thanks
