chemical smell when heat is on ???
We have central air/heat. It's in the 30's here in Florida so we tried to use our heat for the first time since last year and it's giving off this chemical iodine smell. This isn't the burning hair smell, it's a chemical odor and it won't go away.
We had the heat on all night long and I woke up the next morning and smelled it. No headaches, no one is drowsy, just an awful smell.
Not sure if it's bad for us so I wont turn it on again. ( I did try it again this morning and that smell was there again so I turned it off)
What could this be? Any ideas? Unit is 6 yrs old and serviced yearly.
