We ended up removing all the attic insulation and duct work and replacing due to rodent damage.

Also noise travels through duct work and pipe chases.

This may involve adding ductwork, installing a separate HVAC unit, or using portable heating and cooling units.Electrical: Another important consideration is the electrical and plumbing systems.

It needs all new HVAC - duct work.

It has a slate roof and carriage house doors on the garage.I want to preserve most if not all of the classic features of this house.Unfortunately the HVAC system is 25 years old and the electric is outdated with only 50 amps coming into the house (according to my electrician – don’t know how the HVAC was able to work).My thoughts are to replace the outdated HVAC with a 2 zone system, brand new without running any duct work through the cedar wood closets (the rooms have plaster walls so I may end up running the duct work behind the walls and sheetrocking - can’t use existing duct work, btw).

Honestly if they need to store a couple suitcases I wouldn't mind, but it's easier to start strict and go more lenient afterward then the other way around.The second is most tenants are not careful about things in the attic like A/C duct-work and will lay or drop stuff on them causing damage and possibly extra wear on the unit since it is now cooling the attic instead of the living space or has restricted flow.

The main difference was installing a second gas furnace and separating all the duct work.

You can add the ductwork, or closet, or wall off a door to get the sf (and value) added to the house.

Smoke remediation requires cleaning not only the surface smoke, but also all that permeates into the HVAC system, ductwork, crevices, openings from electrical and plumbing, ventilation units, light fixtures, appliances, cabinetry, countertops, carpeting, carpet pads, walls, and woodwork.

It's sprayed on the walls and floors, but the biggest concern to me is the ductwork.
