We live in a rented house with an old furnace duct system (probably 1960's). There is asbestos-containing duct-wrap all around the ducts, and it starts to crumble in some places (it's located in the attic).
I want to make sure that it is safe to use the duct system.
My question is: what type of companies / professionals should I be looking for in order to do this kind of inspection? (we live near San Jose, CA).
Thanks in advance!
Background:
This question, and a breakdown of professionals that I have spoke with:
HVAC cleaning companies: don't want anything to do with it.
Asbestos companies (like Benchmark environmental, EnviroCheck): propose to take samples and see if the material is asbestos or not. They don't do an overall evaluation, or even promise to look at the entire duct system.
Other HVAC companies: "we don't clean ducts" / "We won't touch anything with asbestos" etc.
