Close up and personal view of a heat exchange in the furnace. From the inspection I did 
yesterday, It looks bad and this was confirmed when I activated the unit… there were so many holes in the exchanger that the flames were sucked out at the burner! Use of such a furnace would have sent spent carbon monoxide gases right out the registers and into the rooms! This was an easy find for an inspector who takes the covers off of furnaces to see what they can see.
