[@billymckee9438]

Up until this video I was convinced I would pay top dollar for this house. I know nothing about HVAC but a lot of stuff just seemed sloppy. Came to the comments and confirmed that.

[@scottbishop2532]

Best is to install metal ducts; flex duct is rat food and has a much higher static resistance. Also dogs cats and animals can get under a house and destroy flex. All you do to assemble a 5' section of round metal pipe is snap it together and run a screw at each end, tape seams or add duct butter, then throw insulation around it before joining it together.

[@metta4567]

Yeah wish I could upload pictures in the chat, last winter some animal chewed through my mother in laws newly installed HVAC system with flex duct and foam board plenum "not what I would have used" and made a home in there, my mother in law called me and said insulation is blowing from her vents, I immediately knew what was going on still sucked because she paid for this system, the installers removed the metal ducting that was installed in the 60s when the house was built, it obviously flowed better before, not sure why they didn't just wrap the existing metal ducts, but they were nice and left the mess in the attic.

[@SammyInnit]

Using that amount of flexible duct will lower efficency and drive up energy costs due to the amount of resistance. I fit ductwork for a living in the UK and I'm still amazed at the amount of this that's used in the states.

[@tomswinburn1778]

[@mikescheve429]

The overhead view of all the duct work is fantastic. I hope you continue to keep posting overhead shots like that as construction progresses. Cheers!

[@natehicks8939]

Well here are a few things that I noticed that your Mahalo heating company needed to do but didn’t as your video showed. The guy cutting out the holes in the side of the rec duct didn’t fully cut out the hole, the rec duct was not the correct size in height for the size saddles they used so there is an air flow restriction right there. when they joined the rec duct together they apparently did not use mastic to seal the S & Drive cleats. when hanging steel duct work the weight is substantial and hanging it with nylon strap is beyond ridiculous, that strap is intended for flex duct. They never put mastic on the saddle before putting on the flex duct, apparently more potential air leakage. just because they ran the flex duct straight does not take care of friction lost. It is good they ran it straight but it needs to be installed pulled very tight. There is a helix in the duct that accounts for a lot of the friction lost and even more if it is not pulled very tight. Those adjustable 90’s they ran off the boots should have had all the segments duct sealed with mastic once adjusted into their final position, again for air leakage. Seems to me just going by what you said narrating the video and the footage that was taken, there is a lot of lack of details that are going on in your builds by your heating company. The most important day of an HVAC system is the day of its install. The end user the person purchasing the house is the one that looses in this situation with higher utility bills lack/loss of comfort. I wrote this not so much to be condemning but to point out the lack of detail being displayed. If you spoke to the management of this company and suggest they tighten up their practices it really is just minor adjustments needed that will produce a much superior product. Yes steel/metal ducts in the long run cost more but is such a superior product used in an install. Of the decking is off and you ran those then it would lesson the cost of it. You could point that out as a high quality design and reflect it in the cost of the house price. Really is such a better duct system if you used a graduated trunk line!

[@mbass1793]

Nate Hicks totally agree. The best way to balance is with system design.

[@PVS3]

How much of this fall into the category of "This isn't Phoenix or Minnesota" and therefore is less impactful? I get if a system is going to be doing a LOT of work, then a 5% reduction in efficiency matters. If the climate in this location isn't going to require this system be a workhorse, it might tip the scales on cost v benefits. Case in point, some areas of the country you'll still see a decent number of window AC units, despite the lack of long-run efficiency, because they're only needed 3 months out of the year. Is this system "good enough" for this application, that adding more costs to make it better won't actually improve performance in a meaningful way (given how it will be used in *this* house)?

[@paulchurnock6465]

The duct leakage and losses in this system will be ridiculous, and regardless of the local climate, the energy usage will be much higher than it needed to be, solely because the contractor didn't care.

[@natehicks8939]

I’m in the state just north of Oregon, Washington state and specifically western Washington and that is code here.

[@DustynRougier]

I have been the doing HVAC for 9 years, 4 of which as the foreman, and I 110% agree with everything you have stated. Watching this made me cringe too many times. The main issue was how little mastic was used on the entire job. Another big issue was installing uninsulated register boots, especially outside the envelope of the home. Those things are gonna sweat like crazy. Also should have used a light coat of mastic over all insulation tape to help with separation.

[@shawndinterman2219]

Amazing to see how things are done in different climate zones, in South Dakota we do conditioned attics with air handlers running thru the walls and stud bays framed for returns

[@smtte9942]

[@grnsmoke3307]

I have never been so addicted to a series of any kind like I am to this. Waiting for new episodes is painful! Love the channel!

[@michaeldougfir9807]

Long ago, when I was fireman, I learned about "friction loss" in CJRL or, cotton jacket rubber lined fire hose. It meant that your hose conducted less water, at less pressure, the longer the hose was. All the little ripples in the hose cost you something. And each additional appliance (fitting) also cost you something. So the engineer back st the pumper truck would figure what volume and pressure to give you, so that what came out of your nozzle was what you needed, or requested. I see that there is a similarity in these HVAC ducts. Now, as a retiree/arborist, I use scrap pieces of that same hose as sheaths for my pruning saws. A big enough piece can be used to protect the teeth on a misery whip, or on a chain saw bar.

[@BobbyFromNJ]

As a savvy DIY homeowner, I would be pissed to find that much flex in the system. I know cost is always a factor but jeez, how hard is it to run 80% of the branches in solid tin? Use 20% flex where it has to twist and turn in weird places to save some labor.

[@athhud]

Completely agree. I am far from an HVAC Pro. Just a homeowner that prefers things be done right. I’d be embarrassed to claim this work as my own.

[@philthycoder]

The right way to run flex, and the cheapest way that is still performant, is to do only the straight runs in flex, pulled tight, with rigid elbows/connectors wherever the duct has to turn a corner. Agreed that I'd be pissed if someone tried to install this all-flex ductopus in my house.

[@DustynRougier]

I do 95% commercial and industrial installs, and they limit the amount of flex able to be used. We are only allowed 5' of flex per run, and it must be at the end of the run per mechanical specifications. I understand that occassionally hard pipe is not possible, but they didnt even try.

[@clayd9477]

Rule of thumb on our jobs is 5 feet of flex no more. They sell pipe for every size.

[@markklaus4558]

I agree... I was surprised to see any flex at all in the huge crawlspace...

[@pdxwill8524]

Scott, A shout out in the show notes for the background musicians would be great.

[@faded9043]

Any runs over 10 feet should be hard pipe instead of all flex. I've done commercial and sometimes would have to hard pipe all the way to the registers

[@WobblycogsUk]

It's fascinating to see how houses are built in the US, it's so different to what we do in the UK. I don't think I've seen a house that has air heating / conditioning like that, we pretty much use hot water and radiators to move heat around. It means more plumbing but it's compact which is a benefit in our tiny houses. Of course a wet system can't do cooling but that's not a problem here.

[@yogiontour]

Just wait for a bit of global warming to kick in haha.... I think you will start to see the use of more US style systems when the new regs come in, they are phasing out gas boilers in the UK so we will have more split AC and central air systems for sure. The heat pump will be king....right up until we get -5 winter days! haha

[@DiHandley]

That’s the way we do it in Australia too. No boiler or radiators just air ducts that sometimes also double for cooling.

[@danielmclaughlin2137]

According to my air conditioning mate, there's an increasing trend for domestic residences to have air-con for heating and cooling. According to him, its more efficient than using oil or gas, and I suppose if you were getting your electricity from renewables it would be more environmentally friendly.

[@yogiontour]

@@danielmclaughlin2137 Yeah split AC units are now rated with a coefficient of performance of 4 or more. Which means in optimal conditions you get 4kw of heat out for 1 kw of electricity in.

Hopefully you are able to keep the duct wrap from getting wet.

The ducts also need to be insulated to prevent condensation on them. So it's pretty important the insulation is good.

[@elsdp-4560]

THANK YOU...for sharing. Enjoyed.

[@Dnelson807]

Even with the understanding that different people do things different ways, this is concerning. A longer trunk line with shorter hard duct branch lines performs far more efficiently that this system. A short trunk line and long flex branches will make this system work much harder to condition the air. The flex lines will also break down in the short term, collapsing and leaking. This will increase the maintainance cost of the entire system considerably, and by much more than the cost of putting it in the right way. I have been in many many crawlspaces to repair plumbing and seen how badly the breakdown of these types of systems happens in just a decade or two.

[@JohnnyJr396]

Dan Nelson BS ! if sized right and TESP is right you’re good.

[@joep8520]

@thepreachingplumber I agree. I personally wouldn't install flex, but I understand it, especially in their climate. My biggest issue was the length of flex used; shorter and straighter is always better and more efficient. This really is just a plenum system with a spider of flex coming off of it. The only real disappointing part of the job so far. It wouldn't have cost too much more to have an extra joint or two of trunk line, and would have made a world of difference in the overall efficiency of the duct system. Also I was blown away to see 8" runs used everywhere. Not even a 4" for a bathroom... Then again maybe they used 8" to make up for the inefficiency of the flex duct...

[@ryanpetersen3377]

I have to agree. I’m a project manager for a commercial mechanical contractor in Minneapolis... and a couple things about this wouldn’t fly here. First, there is a code limit to the max. length of a flex duct run. I believe it’s six ft. They are way over that. Also, flex duct eats up way more fan static than hard duct. So, the points made about air balance are likely nullified because I’m betting they are not getting the air quantity that they should be. Finally... and I understand this is residential, not commercial, and I fully understand Mike Rowe’s point about “safety third”... but the lack of PPE used by all the workers in this series is alarming to me. Here, in my market, you’d have OSHA violations stacking up left and right! That said... this is a truly fantastic series and I’m thoroughly enjoying it!

Where I live solid sheet metal ducts with insulation around them is the norm for single family homes here! Gas fired Forced Air heating via gas furnace with an A-Coil indoor coil on top for central air is normal here as our summers are often over 90° and can hit and even surpass 100° for a week or two summer on average and if you factor in the high humidity it can feel up to 20° hotter with the humidity, winter we are often under 28° with constant freeze/thaw cycle sometimes almost 60° during winter thaw cycles!

The flex duct would be fine in "some" rain, but the large distribution box, would not, its wrapped with batt. Nothing a piece of plastic would not fix, at least for awhile. When I used to install HVAC many moons ago, we only used Pipe, they didnt even have flex, pipe is really easy to clean correctly. But still alot of work and work costs money. I put in miles of that stuff. I homes, apartments, and business places, but hey that was 1970. Now its blow and go. But they for sure better cover those vent boxes, water in that flex duct will get moldy, not good. Otherwise normal job.

I live in North Texas. Our house was built in 1970, and we bought it in 2000. From my experience, using the crawl space to put the duct work in is only viable if you can guarantee the crawl space remains dry. Ours flooded after rains, so we had to move the ductwork to the attic and put French drains and a sump pump on the uphill side of the house.

You made a comment abut tradesmen not having to work in a dark crawlspace by letting them do the work before the decking is installed. For only a little more money it would be simple to install lights throughout the crawl space with extra lighting where the air handler is installed. That would allow tradesmen to work in well-lighted conditions for the life of the house. I've installed lighting in many crawl spaces and it makes a world of difference to the folks coming in for future repair work and even for the homeowner to periodically inspect the space. I would also consider putting a platform over that drain pipe since it cuts right through the access area. Better to keep people off the pipe entirely...

Your video's are always spectacular!

WOOO! When I heard the word PEX I went WOOOO! I love that stuff. Re-plumbed my parents whole house with it when the 30+ year old copper started pin-holing.

The drone shot at the end is incredible!

You guys have the best music. 👍

This is my trade on the Commercial side we are finishing up a Hospital in Palmer Alaska and our duct is 2" water gauge with a 2% leak loss. Talk about tight tolerance. Love your videos 👍🔨🥾

PVC PIPE?

Scott, you have a silver spider hiding in your crawl space.

I would close the vents in the floor as critters, dust and water can get in like this, hard to clean it out

[@jboyd85]

I've always wondered why you yanks go for flexi-systems. Where I'm working in Ottawa, Canada you see solid ducts in virtually every residential building. Heck, we can get a 6" round of reasonable gauge for $2/foot. In greenbacks that must be less than $1.50/foot. Why not go the extra mile in durability knowing it may be in a wall or floor for a hundred years?

[@andrewalexander9492]

Jeff, I wouldn't extrapolate too much from this one example. Reading the comments here, I get the impression that there's a lot of areas in the US where using flex duct like this wouldn't meet code.

Nice!

[@DetailEnthusiast]

Interesting to know how easy it really is to diy. 👍👍👍

[@christophersines8238]

It’s also about not taking up air from the crawl or attic space into the ducts. Any leaks will pull air from unconditioned space into the ducts with the Venturi effect. But I’m only speaking from a NADCA point of view.

Overhead shot was nice. So is seeing PVC in Oregon. Just moved from Chicago and here in Portland it’s abs...

[@nat8843]

Perfect music soundtrack!!

[@robfoster5516]

I guess we all got different ways depending on where we living, not much call for blown air here in Yorkshire UK but for me still a great video. Real quality channel guys.
