Homeowner has a 2 year old high efficiency Carrier GFA w/air and a very strong odor coming from the supply side of the system when the heat is on. They state that they heard a loud noise from the furnace and began to smell this odor shortly thereafter. The noise has since gone away, but the smell hasn't. Coil, pan and humdifier water panel are clean. To me, it smells like some type of chemical. I was in the home for an hour and experienced some irritation to the eyes and respiratory tract. Coil was fitted properly and there are no openings around it for anything to have fallen thru to the heat exchanger. Any suggestions?
