Asbestos INSIDE ductwork??
Sorry if this post is a duplicate but I couldn't see where my original posted.
I am getting quotes for a new ac system (condenser, furnace, ductwork). One of the companies said my ductwork was insulated on the INSIDE with asbestos. They said ductwork looks like metal but is actually cardboard and lined inside with asbestos, but they didn't touch it to see if it was actually metal or cardboard. House built in 1973 in So California.
My best quote so far is $7900 for A NEW 5 TON RHEEM MID EFFICIENT 14SEER AIR CONDITIONING CONDENSER WITH A 80% FURNACE. Includes new R-8 flexible ductwork and bar type registers. Will use the new Carrier coil that was replaced last week by home warranty.
My questions are: (1) is asbestos insulation INSIDE ductwork possible? I can't find anything concrete about this online. and (2) is Rheem a good ac system? Thank you!
