Looking inside a floor register I was forced to wonder how much duct clog is too much duct clog?!
It was nasty!
Air could hardly blow through the duct!
In an email I teased Charlie Buell saying that I thought I saw it moving, and morphing, and wondered if it was producing methane gas.
In another email I also teased Don Hester and asked how much goop the code allows inside a duct. Apparently, in Virginia, it is about 4". This is a clogged artery!
Worse still, the other floor registers looked the same!
I'm pretty sure it tastes like chicken. Doesn't everything? Please bring your own spoon, and no double dipping, please.
You have to wonder about air quality in this house!
The duct cleaning companies might beg off of this job! Or charge a dramatic premium!
The EPA says (click here) some interesting stuff, and, of course, it's answers are indeterminant. As to whether duct cleaning helps physical health, they say: "The bottom line is: no one knows. There are examples of ducts that have become badly contaminated with a variety of materials that may pose risks to your health. The duct system can serve as a means to distribute these contaminants throughout a home. In these cases, duct cleaning may make sense."
So, what do health risks you think are being distributed around this house? I don't know and I don't want to know!
My recommendation: at the least, cleaning ducts helps air flow and HVAC efficiency. It cannot hurt to clean duct dust and stuff. Looking at this photo, THIS would be the definition of "duct stuff!" Don't let this happen to you!
