This sounds extreme, but you wouldn’t believe what we find in ductwork. I can’t say we’ve found anything like a small dog, but we have seen everything else imaginable. Everything from long-forgotten victims of DeCon to lost pet turtles that now resemble small ashtrays.
You see, even though you’re the best housekeeper in Colorado, what about the person who lived in the house before you? Unless it’s a new house, you don’t know what stuff remains in the ductwork from previous owners.
Stuff that depends entirely on what their hygiene, house cleaning and smoking habits were (not to mention how they took care of their pets).
In most cases, it’s probably better that you don’t know.
You can be certain that if your furnace ductwork isn’t clean, you’re breathing air that passes over the accumulated dust and crud from everyone (and everything) that has ever lived there.
I hope this unpleasant picture doesn’t make you swear off breathing completely.
Remember, it’s still safe to exhale. All is not lost, the debris will be totally removed when you have your system cleaned by a thorough, professional company like mine!!
