I bought a 95-yr old house in December and I'm refurbishing to become a traveling nurse rental house. Projects consist of remodeling the kitchen, painting the interior, and some landscaping. BUT, sometimes you encounter the "while your in their" projects.
Since I have the kitchen subfloor mostly pulled up in the kitchen, I'm able to access the underneath of the house. This is where I discovered that most of the HVAC ducts were leaking at the seams. The entire ducting system was 3-4' pieces screwed together with 1 single sheet metal screw and then taped.
I replaced the entire under house ducts with insulated flexible ducts (about 9 of them). I finished the last one last night. Lots of crawling around on my stomach military style but I'm very happy I finished the job. It took me a week.
Now back to my electrical work.
