Removing our air vents

My youngest brother & I bought a fixer upper beach current home in a wealthy neighborhood, then it is also a historic neighborhood & everything done to a beach home has to be approved. On top of that, you are supposed to hire job done by a real business! My brother and I are mostly avoiding the fact that we are majorly changing a historic current home & doing it all ourselves, and the greatest thing to hide is that we want to unfasten the HVAC duct inside of the home. The current home came with central air conditioning & HVAC duct. The AC no longer runs and the HVAC duct is rusted & worn apart. An HVAC duct sealing appointment could not even repair it. The people I was with and I need a current air conditioner in the first place. My brother says that ductless HVAC is much better, however not only is it cheaper to use, but it can be used for HVAC zone control, and so what we really need to do now is unfasten the HVAC duct quietly without anyone seeing us, then ductwork removal is not a production. My brother & I need to tear down the walls & ceiling. Then we need to reef several inch metal ducts out of the current home without it falling down. After all of this I need to drive the HVAC duct in the back of my option up to the dump, however what are the occasions that no a single hears or sees any of this? We have been trying to eventually do the job in the middle of the night. It is horrendous & not going well. There is a very big reason as to why professionals do the job we are trying to do.
