Currently I'm working as a basement ductwork installer - a ducter. Every three days I'm starting a new basement job and because I'm working six days per week during one week I'm doing two basement jobs!
So, if you have any questions about work that should be done in a basement such as:
furnace, cold air boot, plenum, ductwork, cold air returns, heat runs, venting, condensate line, etc installations feel free to ask them below.
If your question is already answered in one of the chapters of my Ductwork Installation Guide e-book I'll send you a link to the parent page, if not, I'll take some pictures, write some comments, include it in the appropriate chapter and I'll let you visit this chapter absolutely free of charge!
If you have any questions about Rough-in ductwork installation you are welcome to ask these kinds of questions as well. Almost every day I'm working next to the house in this stage of construction and I also can take some pictures to support my answer to your question.
