Looking at the pictures more closely it is not even the date of when they were here. I had a small locally owned independent company come out to give me their opinion. They found NO cracks and stated the duct work is totally sufficient for my home. I feel I was perhaps scammed. Independent contactor restarted furnace and ran carbon monoxide test and detected absolutely no carbon monoxide. I hesitate but am inclined to inform authorities of possible deceptive business practice.
