Did another in a never ending series of practice inspections yesterday.
While checking out the furnace, I noticed corrosion up inside the dilution air intake.
Since I am new to the profession, wanted some other opinions. Is this telling me they may have a drafting problem that's allowing corrosive exhaust to vent back into house? Or do they all look like this?
Thanks for any help. SOOOOO much stuff to learn! ![icon_smile.gif](upload://b6iczyK1ETUUqRUc4PAkX83GF2O.gif)
