Thanks Wayne I was going to point that out!
Michael Larson has a problem with XXXX.
KEVIN seems to have forgotten to include “routinely”.
What I posted was also from the epa link.
I gave the specific situations were cleaning should be considered.
Do you have a problem with that?
Take it up with the EPA
And I should believe you why?
As usual, you make an incorrect or incomplete statement and then refuse to amend your comment.
You know where you can put it.
You have not changed.
Other than you being a dip **** all the time not really lolol.:roll: BTW you also just posted what you wanted .
so with that if any one cares here is the full link
All I had to do was show that the statement was incorrect. Nothing more dippy.
KEVIN is the one that has a problem with facts.
Huh?
Why all the wasted space?
More room to catch the mice. Did you note the mice bait?
What I noticed was a very poor architect.
To get back to the question;
Return air; stud partitions ok if limited to one floor, and isolated with tight fitting metal or 2" wood. IRC 1601.1.1 UMC 602.1
Supply air; stud partition NOT ok for supply air. IRC 1601.1.1 UMC 602.1
If it is new construction (not a 100 yr old house) there is Nothing Right about it (in my book). There are so many things wrong with it, I don’t have the time to list them all.

In the 1990s, duct cleaning research conducted by Canada Mortgage and Housing Corporation (CMHC)1,2 and the US Environmental Protection Agency (EPA)3 tested house and duct performance before and after cleaning. Researchers observed little or no discernible differences in the concentrations of house airborne particles or in duct airflows due to duct cleaning. This is because ducts are just metal passages.They cannot create dust. Most household dust comes from outdoor dust that has been tracked in or blows through windows or other openings. ‘‘Dust’’ is also created by human skin and hair shedding, pet debris, fibres from carpets, clothes, bedding, hobbies etc. In fact, as you walk around in your house you raise a small cloud of dust particles wherever you go. Dust will be present in one form or another whether you have clean ducts or not.

EPA does not recommend duct cleaning either!

Looks pretty hot!:mrgreen:
I remember that one Roy thanks for pulling it up on the MB.
Just in case some think I am picking on Duct Cleaners.

2009 International Energy Conservation Code
403.2.3 Building cavities (Mandatory). Building framing
cavities shall not be used as supply ducts.
Do you consider a return air a “supply” ?
Same here. Cape Cod cottages. !950-early 19960’s
I did scratch my head but followed the path or flow into the furnace. No issues. metal over joists.
My bad. Not enough coffee.
I have only recommended duct cleaning once.
Oppps. Twice.
Now construction. One year old. The filters where off the seats and the entire condo ducting system was dirty with new construction dust.
The last on was Sunday.
The ducts were extremely dirty and the home was dusty with dust webs and organic growth in the water closet.
Other than that I have read the articles from CMHC.
I do not see a need.
As Kevin expressed, a duct inspection is logical…
Thanks.
