This is the best video I've seen on this and this poor guy ended up with 705 subscribers and not even 100k views?
Our society is so over.
Thank you so much. I need to tape mine and now I know how to do it right thanks to you!
If you're replacing the insulation, it's definitely a good idea to make sure that all of the joints are sealed as air leaks represent heating and ac loss that isn't getting into your home. The average home losses 30% of its heating and cooling through these leaks. I had the chance to interview the folks at Aeroseal which seals your ducts, throughout your home from the inside. I put the link to Aeroseal in this videos description since I couldn't put it here.
When you replace the insulation on your ducts be sure to not compress it. It's the air trapped in the material that provides the insulation and if you compress it you lose the R-value so don't use any straps or tie wraps to tighten it.
Do you have a single filter on the cold air returns that is at the furance or are there multiple filters at each cold air return within the room? In either case those filters should be getting dirrty quickly if the dust and fiber are on the cold air return side, where the air is being taken from the room and sent back to the furnace. They are typically on the ceiling or high on the wall to keep the air circulating.
Nice how they use this easy attics to show how to do it. Look this very low hell attics and show how to do it.
My thoughts exactly. A couple 2'x2' pieces of plywood is a must for us crawler guys
A DIYer has the ability to pick a cloudy, rainy day to play attic worker (Such as myself). I have some attic duct issues I need to fix. If you stuff more insulation into an attic like shown, please install a ridgevent system on the roof and make sure there are sufficient soffit vents. The triangle vent in the end wall tells me there are likely no other vents in that attic.
Does the metal duct work have to be sealed around the joints before you put insulation on. My insulation is wet.
question... is will the fiberglass contamination eventually work it's way out of our supply lines? We understand that you can't very effectively clean flexible duct work and it may damage the ducts themselves, causing further problems. ?
we just had new ductwork moved to the attic (from our crawlspace) with the idea that it would improve air quality. However we seem to have MORE or the same amount of air quality issues. Possibly that the ducts were contaminated with dust and fiberglass before installation and not sealed properly from the beginning (we are trying to redo the work ourselves). but we have a ton of dust and particulates now being blown around our house even with our huge filter system! ? Any solutions?
what type of tape do you use johnny
can i air seal with foam over the insulation that wraps the ducts (ducts are in the attic)?
we thought we were doing a good thing and even got something like an R8 value flexible ductwork. It does the work.. but we wonder how long, if ever, will the dust and fiberglass (from only being open a day or two) will keep being an issue!?
We moved it because we had problems with mold and mice in our crawlspace and thought it would be cleaner and easier to maintain from above.. I guess we messed up.
If the problem is on the the other side of the filter in that a lot of material was in these ducts when installed then there is nothing to keep it from blowing back into the house. I think your only option is to have a duct cleaning company clean the new ducts from the air outlets in. Attics have a lot of dust and fibers in them so if the installers were careless they may have introduced it to your duct work.
First I love your channel many great videos !! Why didn't you rip that insulation the rest of the way off and mastic seal all the joints and leaks ?? Didn't you have to fix this because the tape failed. The tape you just put on it will also fail sooner or later. I would've used panduit straps ( large cable ties) other than that great job probably saved the home owner big time
I don't think my partner put filters on the returns.. just the supply lines, as we believed that the filter at th efurnace would catch any particulates.. but I have read that they are not effective at catching fiberglass...?
Are you replacing failed tape with the same type? That won't do any good.
The best way to fix this is buy a p35 stapler and staple it together I insulted thousands of feet of duct cause I’ve been installing duct and done HVAC since 1998 and we never tape it only where the duct joints are tape never lasts holding duct wrap we call it together that’s why most company’s around Massachusetts staple it together.
If the ducts got contaminated with dust and fiberglass from cutting them it would hopefully settle out over time. There shouldn't be an ulimited supply of it in the ducts. Other than redoing it section by section, and not cuasing the same issue again, there aren't a lot of options. I'd give it some time to see if it does clear itself out. The mess isn't fun.
If you're feeling air escaping, I'm not sure sealing the insulation without sealing the actual duct joints is going to solve the problem. I have the exact same issue, but I think I am going to be ripping off all the old insulation and sealing the duct joints first.
That’s the air handler, part of a heat pump system. Air will only get into a return not a supply.
our installers were definately sloppy.. They had to get up into the attic via our bedroom and while we tried to cover everything, they kept tracking more and more through the house and every night my partner had to clean and vaccuum. It was a real pain! We thought they knew what they were doing... guess not.
Can I put new insulation on top of the old insulation?
I'd like to know the answer to that question also.
I am tech and my opinion is yes I did it on my own house 👍🏻
that is entirely possible and unfortunate. We have a 3 stage filter. One of the filters is like 4 inches thick. Plus we have a humidifier (which we don't believe is working effectively and blows dust as well..?
We added some filters to our supply vents, and some we used tack cloth to ensure any insulation would be caught. My partner exacerbated his health issues by trying to remeditate the work the installers should have done!
