Basement ductwork has asbestos tape with corrosion and holes in the ducts.13.

Also duct work was installed backwards with returns on exterior walls and supplies on interior walls.

Most of it was self performed with the exception of some bigger tasks like painting, flooring, duct work tree trimming.

Rehab-Tear down walls to create open concept-New Ikea Kitchen on main floor with higher end finishes I purchased afterwards (previous owner had business and kitchen was upstairs) -Tore out old water radiant heat and pipes -Installed brand new Natural Gas HVAC and all duct work-New flooring on main floor -Redid wood stairs that were covered with carpet -Installed new fenceLoved the journey however long it took!

For example, I had to order a special sink due to cabinet fitment issues, there was some hidden ductwork issues that I did not see when I inspected the property, labor took much more time than I projected, old pipes/ parts breaking due to age, wood rot around window frames was worse than anticipated etc.

@Steven Wilson ya the duct work is right inside the wall behind the stairs.

What are you doing with the HVAC-duct work or just the unit itself?

I am glad I spent the last few months air sealing the place, adding insulation, and replacing leaky ductwork. 

New roof shingles, paint exterior and interior, replaced old carpet with LVP throughout, new kitchen cabinets and countertops, new exterior siding, reglazed tub and tiles in bath, new bathroom vanity, installed new ductwork and HVAC.What was the outcome?

Window units or even mini-splits are not as desirable when you already have duct work in place.
