Suggestions for recommendations
Have a situation where in the home inspection we discovered some rust in air/heat ducts that are located in the concrete floor slab of the house. The master bedroom especially has a small hole that has rusted through in the bottom of the air duct and further down the air duct you can make out more rust and possibly rust holes. This was the major problem, as the other only occurence of rust was in another bedroom and the only rust was where there were three nails located on the ducts further down.
Thinking of suggesting either concrete be poured in and all new duct work be done from the ceiling or just busting up the concrete in that master bedroom and replacing the duct work in that particular room. Here is my concern, from the photos I was able to take of further down the duct work in the master bedroom, there appeared there was a water line mark which was past the last rust that appeared to be holes. Supposedly they had high rain water close to flooding at some point last month and water might have gotten into the air ducts.
Should we recommend a restoration company or a HVAC company to be able to make these types of repair (running new air ducts or busting up the concrete and replacing the duct work)? Or is there other alternatives that we can suggest? There is a coating and lining service in town that we have used on a house we owned that showed some light rust from moisture, but since this hole at this house is on the bottom of the duct, I'm thinking there might be a foundation problem, though nothing we could visibly see. Might even be a leak from the master bathroom shower drain?
I'm thinking probably test for possible mold too?
