How Sealing Attic Ducts Reduces Total Home Air Leakage

www.drenergysaver.com | 1-866-607-0191
Welcome to On the Job Episode #73! In this episode, we will discuss the impact of leaky air ducts in the attic on the total rate or air leakage in a home.
Many of our On the Job videos explore the energy consumption and comfort problems caused by ducts that run on unconditioned attics.
We also have videos that explain the way air moves inside a building, the pressure differences between the bottom, top, and middle levels of the structure, and how air leakages in the attic have more of an impact on energy consumption than air leakages in the living, or conditioned spaces.
The air that leaks through air ducts in the attic is air that you pay to heat and cool throughout the year. This is air that is not getting to the rooms that it needs to heat and cool.
The test in the video will show that even when the air handler is not running, air from the conditioned space is still escaping through the ducts.
Exactly how much air escapes?
With the help of a blower door test, Larry Janesky, owner and founder of Dr. Energy Saver, will test a home with unsealed air ducts in the attic, and then run the same test again after the ducts are sealed.
With no other air sealing work performed, the results show that in this particular home, the leaky ducts alone counted for 8% of the total air leakage.
How much air is leaking through ducts in your home? How much more comfortable would be the rooms in your home with this simple and affordable improvement? How much would you save in energy bills? Contact a Dr. Energy Saver dealer in your area today to find out!

What product was used to spray and seal the attic ductwork? Is that product (or a similar one) available to the DIYer?

[@publicmail2]

I what a life time attic duct work not the fiberboard we use in FL. I'm thinking of metal with spray foam over it.

8 yrs later what happened

[@larryjanesky8185]

This work makes an amazing difference. The fact is HVAC contractors have built millions and millions of big problems - leaky under-insulated ducts in hostile places (attics). And all this was done under the auspices of the code who watched them do it and approved it. Homeowners are the big losers from all this. We are happy to be fixing these terrible problems one by one. Duct mastic won't do the job.

What did you do with the hair Larry?! Haha, I love what you and all Dr. Energy Saver affiliates are accomplishing. I'm an Energy Specialist and I deal with all the issues that you address. Your video series has improved my confidence to deliver soulutions to my customers. I have had my attic air sealed and insulated by one of your affiliates, am planning on the crawlspace next, and look forward to hopefully new videos.

How can this be code approved. when was closed cell foam an aplicable duct sealant? Mastic is code approved not close cell. Don't do this type of work it is sloppy. I work in the spray foam insulation and HVAC industry this type of work is what I would condemn.

[@Polished1115]

+Kristopher Kirby What's the problem with using closed cell? Is there some type of health hazard produced? Just curious what your thought process is.
