Title: HVAC Apartment Insulation Replacement Needed?
Post by: wella on October 12, 2023, 01:31:42 PM
Hi @all and happy tuesday

I got 2 questions and observations here.

I am located in Florida - Miami. The AC brand is a bryant Model No. 517EN036 (Apartment complex was build in 1988).

1) A company serviced my AC Unit and they did not mention the dirty insulation within the HVAC. I was able to capture photos of it. Should that be replaced, If yes what is the name of this type of insulation?

2) The company recommend me to change the whole duct system in my apartment complex to change. It looks a bit dirty and the type of material is different from what they have shown me. The type of new duct they showed me had pure insulation type of tape inside. The current duct has this weird material, not sure what the name it is (attached below images). Is that recommended to change the whole duct system, since they would need to open up all drywalls? Is there a way for them to insulate it better with the current duct system which I think may be difficult but I am not sure what tools and material are out there.

A professional duct cleaner will have equipment to clean insulated duct without damaging it.

They will?

Ive never seen a real succesful way of getting that insulation cleaned.  Just blowing/sucking doesnt work.  And those rotating agitator thingies either dont do it, or rip the insulation to shreds

It's a pain if you damage it because you don't want fibers blowing around.  They can spray on an antimicrobial coating that will help prevent that.

Here is how it can be done,
