Watch InterNACHI's Home Energy Instructor, Joe Hall, inspect ducts, pressurize them with a duct blaster, and seal up the duct leakage properly to prevent home energy loss.
I'm going through my old ductwork after getting a new forced air furnace installed. Great info, here. I've been a Realtor for over 24 years and have been on hundreds of home inspections and I don't ever recall seeing mastic on ductwork (including higher end new construction).
yes agreed very good explanation that was the missing piece of equipment to pressure test hvac vent system. I was trying to come up with a hacked way of using a air compressor , leaf blower, or wet dry vaccum with a hacked psi gage. But this piece of equipment is much more easy to uses and you can uses it for more sensitive measurements like 25 pascals which is very very small interms of getting it on a psi gage.
Thank you, Doug. It was a lot of fun to make. We just built that contraption very quickly, and turned on several cameras at different angles and let the professional home energy inspector speak. And Joe did a great job for us.
The big thing is there is a lot of tests smoke test , high pressure test , this low pressure pascal machine test, thermal cameras , soapy water ,..etc Based on the sensitivity level and the tolerance of the leak test determines what piece of equipment to uses this was the missing precise machine i was missing. Cool stuff.
I’m actually installing an additional duct run for my laundry room (partition wall, ele, plumbing, drywall etc). When I got to my furnace/duct runs I was astonished at how much is leaking! I went to town sealing what I could. I probably would have fired the contractor if I saw his work. Question: Since this is getting inspected.....do I wait for approval from inspector “BEFORE” I wrap insulation? Or do they care?
Wow , eye opening for a home owner. This is the reason why some guys give cheap prices to install a central a/c unit. Quick connections done wrong , after they leave .... the home owner pays the price and reaps the bad air spots and high energy bills.
you probably dont give a damn but does anybody know of a tool to get back into an Instagram account?? I stupidly lost the password. I would love any tricks you can give me!
@Dakari Odin Thanks for your reply. I got to the site thru google and I'm waiting for the hacking stuff now. Takes quite some time so I will reply here later with my results.
You mentioned finding disconnects in the system. How does a system get repaired inside the ceiling? I mean other than cutting drywall. I'm sure the builder of my 43 year old home never did the duct work correctly. Not many things were done right
There's no much we can do to ductwork in existing homes without major renovations, like you mentioned. You're correct. That's why it's important to build correctly. Now, that said, there are many opportunities to air seal and insulate in an existing home. Especially in cold climates, there are many air sealing opportunities in the attic space under the insulation and along the wall top plates. Hire a Home Energy Inspector at www.nachi.org/certified-inspectors to help.
Is it advisable to wrap insulation around basement ducts and outside heating wall ducts (2 that run in the outside walls to the 2nd story in a 50+ year old house)? I already sealed my basement duct seams with the alu tape. Trick I found, rub the tape with a marble or a plastic spoon or top of finger nail will remove air bubbles and odd bends. Just the tape alone, already changed my bill usage from last year gave me a 7% decrease on my bill. I'm wiling to put the work in, just want to near the max duct efficiency with minimal loss. Any and all info will helps thanks.
@@BenGromicko When you have good information, people watch and listen. What type of insulation do I wrap my ducts with? I've looked a home Depo, but the young guys there don't know. So I asking you as a professional.
Not sure. I appreciate that! Thanks for watching. I teach free online classes for inspectors at www.nachi.org/webinars. Free, online, and open to everyone.
I used the kind of mastic which allows to turn on AC in 4 hours after applying it. But can I turn on fan right after this mastic is applied? Thank you!
"If it looks like it was hard to seal, it probably wasn't." That, my friend, is a perfect example of a hanging participle. It wasn't hard or it wasn't sealed?
nice video. very informative , looks easy in the studio, not so easy in the attic over 100 deg.or crawl space,
Thanks for watching!

Got to have the right tools. Thank you for the feedback, Nate.
Very professional video - well done!

Thanks for the vid! Very helpful
Glad it was helpful!

This video was a lot of fun to shoot and produce. It was 20 cubic feet of defective ductwork. :)

Home inspectors won't care to look under the insulation. A code inspector might.
Wow , eye opening for a home owner. This is the reason why some guys give cheap prices to install a central a/c unit.
Quick connections done wrong , after they leave .... the home owner pays the price and reaps the bad air spots and high energy bills.
Yep. Every house should be inspected.
Thank U for the information on Duct Sealing, I just had my Ducts changed and my Air isn't blowing like it was with the old ducts...
Glad it helped.

@Dakari Odin It did the trick and I now got access to my account again. I am so happy:D
Thank you so much, you saved my ass!

So I asking you as a professional.
What's the name and model of the smoke stick being used in the video?
Not sure. I appreciate that! Thanks for watching. I teach free online classes for inspectors at www.nachi.org/webinars. Free, online, and open to everyone.
What brand/model smoke stick emitter are you using in the video?
That's a great question for the presenter.
Is this the same mesh tape that is used for drywall patches?
No. It's metal tape.

Right.
Do you need to clean the dust off before applying the mastic on the duct?
Sure. Could help.
This guy is describing anyone that's hired someone in the past 15 years. Yeah we hired someone to do it but we might as well have done it ourselves.
Okay. Thanks for watching.
"If it looks like it was hard to seal, it probably wasn't."
That, my friend, is a perfect example of a hanging participle. It wasn't hard or it wasn't sealed?
Ha. I love to use dangling participles more though.
Good explanation but you need closeup of what you are demonstrating.
Ok next time.
if u smoosh every connection supply an return one shouldn't have any leaks
Agreed. Thanks for the comment.
Smoke that joint! 🤣
We're in Colorado, so we'll do. :)
Unfortunately most of the sealing that is required in ducts is behind walls, floors & ceilings in real life.
Yes. For existing homes. But it's available to observe the ducts when a home is being built or renovated. And that's a good opportunity there.

Unfortunately company did a hack job on the HVAC when I converted from electric to gas
& it's hard to fix😣.
But thanks for reply.
Use my calibrated hands 😂
Yes.
All Hvac techs should be bpi certified 👍🏻
Sounds like a good idea. BPI approves a ton of InterNACHI's free, online courses at www.nachi.org/bpi-approved-internachi-course.htm
