How To Seal HVAC Ductwork Properly!! | HVAC Installations

[@jamram9924]

I used pookie on all metal connections to an excess because I wanted to seal my new ducting. Four small flex ducts of less than 6 feet and used 2 nylon straps for the inner and outer for each connection from the main trunk. I learned so much from a Master HVAC while we remodeled my home, perhaps a little OCD, but my ducts are tight and all that extra effort sure made a difference in moving cold air in AZ summers...🥵

[@masontroglen3413]

Ik old video. No 1 ever uses spray glue adhesive for the taping!!! Makes a huge difference makes the tapes bond and basically won't ever come off.. over time moisture etc... Like you'll see how easily tapes rip off . Gotta have the adhesives..

[@michaelgonzales803]

Mastik is good but some ppl use it like my kindergarten kid uses Elmer's paste ... all over the unit making it impossible for the next guy to service the systems. So Tape, Mastik and zip ties but use them correctly. GREAT VIDEO ZACK!

[@christianruvalcaba7788]

That's the point of mastic. You can always use a flat head screwdriver or a chisel to take of mastic.

[@caldun5445]

Glad to see you making videos, love the content you put out keep it up man!

[@restore64]

Can you use the butyl/mastic tape over screw heads? I would like to secure my connections with a couple screws and tape over them but I'm afraid the heads will make it difficult to secure the tape properly.

I’ve been taught it depends on what your taping/pookie cause it can make it difficult for the next person working on it.

I’ve just got into Hvac I’m 20 rn and let me tell you guys I will forever look back and thank y’all for giving me the idea to use this “pookie” tape for future dad jokes god bless y’all

I was hoping for instruction on how to tape between a Round flex AC duct, and drywall. I was thinking there was some sort of technique where you cut little lines in the outside edge of the tape so that it goes around a circle better or something like that? I tried to just tape it around but doesn’t come out as I think it should, and because it’s going around a circle it tends to leave some gaps.

[@pnajera3938]

Yessir we use that Srim tape over here in Florida. Good stuff

[@kolef1000]

My furnace plenum and duct above it like first 12 inches going both ways has been sweating lately being so hot and humid. Would insulating this stop the sweating

[@KiwiBrowne]

I need to tape up the hole which was cut in my furnace top for the duct which goes up into my ceiling and out. The duct gets very hot so which product do you recommend? Can you link it for me? This is a fabulous channel, Thank you,

[@lanmech7397]

This is definitely a residential HVAC opinion. You always us duct butter. Wiping that tape down can cut the tape where the joint is.

[@thecoconut104smash5]

Really hope you use mastic itself.

Hey Zack, Question.. What version of Quickbooks do you use? I current use Service titan and was told by several people that quickbooks is better. Looking at Quickbooks there are several versions. I'm a small HVAC business owner myself in Louisville Kentucky.

[@l.a.r.t4ever676]

Hello, Very informative video. Question, when applying hvac tape to any air duct leaks in the attic specially, is it best to turn the central ac off?

[@masontroglen3413]

Yes turn air off, best way just bump AC on automatic up to 86, you'll want it off BC of the condensation not a huge deal though. You could do I while on too really .. you figured this out by now I'm sure lol

[@michaelcooper5868]

I had an inspector plumber look at my set up and he mentioned it didn’t look correct because it did not have a caulking sealant after the tape had been applied. Is this needed or can I just have the tape?

Hi I’m sorry I posted an issue with marijuana fumes on my kitchen exhaust range. I forgot to mention that when I cut the pipe. I took the remainder cut portion of the pipe and I rammed it pushed. It forced it inside the hall that is on the top inside of the wood cabinet. Basically inside ceiling. So I forced the pipe in all the way then I put a sheet of plastic around the end and taped it. I don’t know if I forcing the aluminum material on the hose with a lot of force to go inside the hall might have damage or made punctures on the material. Again I just basically just use force to just push it and stuff it all the way inside. Period I’m thinking if I take off the plastic at the end and pull the aluminum piping that was around into the inside of the hall , back out again. As long as there’s not any punctures because of the force that I used to push it in. But I just be able to pull it out again and add an endcap that I purchased at Home Depot and then seal the edges of the endcap with either one of the airtight tapes that you advertise on the video that I saw , thank you

I cut off duct pipe that serves as exhaust pipe on top of my kitchen range. I have a serious issue with marihuana fumes that enter my kitchen area from apartments below me. Im on a private 2 fam home. I have a serious pot head living under me. I got fed up and cut the hvac aluminum hose that enters my cabinets through the inside top of cabinet. And runs down through the inside of cabinet all the way down to my range exhaust on top of stove. I cut the pioe with a box cutter and wrapped the ends in plastic. How ever it doesnt seem to be addressing the fume issue well enough. It seems that fumes and fiberglass strands are seeping through the plastic regardless. How can i correct this and make this pipe as airtight as can be. I was looking at your video with sealing allum tapes. Can you please help me.Additionally I think fiberglass spread into the kitchen cabinets and furthermore into the apartment. Having serious allergic reactions . How can i fix this myself as best as possible. I have a shop vac w heppa filter and 3M particles mask for fiberglass. I’ve tried to vacuum area but itchy burning eyes and congestion in nose continues.Please can someone tell me how to seal point of entry adequately. Thank you!

I’ve never taped flex lines always used large zip ties

[@HVAC544]

Same here. The only thing I don't like about it using the ziptie on the outer jacket. It compresses the insulation could cause the metal to sweat. I've seen some guys tape the outer barrier. Not quite sure how you would do that if you put dampers in the takeoffs?

[@christianruvalcaba7788]

@@HVAC544 you make a slit on the liner. Easier if it was showed to you.

[@christianruvalcaba7788]

That's how you get ducts to sweat.

[@thecoconut104smash5]

Or how about y'all stop being lazy, told the insulation back. Metal tape. Then use mastic then bring the insulation back and tape it. That is how to install all ductwork. Sealed and won't degrade the eat tape does.

Mastic. Also spray glue!! B4 you put tape down would step it up immensely. Literally. Lol

[@Jamie-po9zk]

[@bentleyjarrard885]

YEP, a bucket of zero VOC 1030 and a 50 cent chip brush = no air leaks.

[@zack9912000]

I like mastic over tape

[@christianruvalcaba7788]

That's called being an ass.

[@justinsexton3140]

Typically yes, but not if there is a pre-construction duct work because that could fail the inspection and plus you wanna mastic the flex duct material to the collar, use a panduit strip on top, then put the outer layer over the insulation, panduit over all three on the collar.

[@ThePeavey23]

Mastic with the fiberglass in it, honestly if your a good tin knocker and cut nice holes you really don’t need it unless code calls for it.

[@mannys9130]

Every duct joint should be sealed, even if the jointing is top notch. System efficient takes a shit with air leakage at any points.

[@masontroglen3413]

Yup and dont forget to spray your spray glue 1st then the tape. . Also ppl slide ducts on too far . You only need a little like finger width, spot weld. Spray glue. You have more bite room for the tape when you dont put on that much. You dont need tons of tape either. With the spray glue, just a couple layers.

Its not about looks really for 1... Sure anyone can dam zip tie a duct or tape a duct on, that does not mean its going to last. Or be sealed proper , just goes to that majority if not all do not do a proper job.. do it right. Clean surface . SPRAY GLUE. Metal tape. Mastic. Boom prepped. Then slide duct just barely on a finger width, spray glue again ALWAYS spray glue for your tape. A couple kayers of duct tape now for the inner duct you just slid on. Done. Now you take the outer liner and curl it in so its neat and the insilation is all the way around no empty spots.. bang cple more layers of duct tape and your done. Mastic. That is the best way youll ever see. It will be sealed forever dam near.and itll look nice too. Chz yea you could use string, a bunjy cord or glue to get the duct on, that dont mean its right or sealed .anywaus hopefully that helps pol live HEALTHIER and happeier!!
