Advice needed on flexible duct
« on: February 10, 2018, 08:20:07 AM »
I am renting a condo where the HVAC system was installed improperly so, among other things, insulation from the building's roof was being blown through the  HVAC. It caused serious breathing issues for me and it is all about to be redone.  They will be using flexible duct (I could not talk them into metal).  I am a bit concerned about outgassing, odors, etc from new flexible duct.  One contractor used the term "hospital grade." Does that mean anything?  I think I have a bit of leeway, though not too much, in asking for something to be used.  I am allergic to many things, including most scented cleaning products, perfumes, etc.    One thing I thought of was asking that they allow any materials to be used to outgas somewhere else for a few days before installing.  Is this reasonable?  I've done this in the past with carpet, but since flexible duct comes squished up I'm wondering if this is possible. Any advice would be most welcome.  Thanks!

I don't think that you'll be able to convince them to stretch out the ducting and allow it to off-gas before bringing it to your apartment. If you have the latitude to make a request, try asking that they use aluminum flexible ductwork rather than vinyl if off-gassing vinyl makes you sick. Good luck!
