New HVAC flex ductwork new plastic smell
About a month ago we had a new AC handler and new AC ductwork installed in our home. Since then we have had a new plastic smell coming from some of the vents. The smell is similar to when you open a new plastic shower curtain or new pool float. The ac company said the smell is coming from the plastic lining that is used in the flex ductwork. The maker of the ductwork has stated that is not possible since they use PE plastic and PE plastic does not off gas in anyway. We were okay with the smell when it was first installed but after a month I would have figured the smell would have gone away. Any ideas? Could it be the plastic lining? And if so, are the off gases hazardous? Could some of the ductwork be defective, which is why only certain vents are effected?
