Advice for beginners: I've been installing heating systems in new homes for over 25 years and I just recently bought a pair of attachable uni-shears for my drill because of all my arthritis, carpel-tunnel, tennis elbow, golfer's elbow and bursitis. I'm pushing 50yrs old and I'm practically crippled by cutting thousands of miles of sheet metal by hand. I also bought that circular cutting tool but can't get the hang of it and getting burrs. I've mastered cutting metal without burrs but the pain in my wrist these days is killing me. I always worked piece pay and the older you get the less money you make. Pick the right employer that allows progression and seniority without bias or you will end up like me. I make less money today as an experienced journeyman than I did in my 20's as an apprentice. The piece pay hardly went up over the years and definitely not in par with inflation. Try to work for an hourly rate where you can.

My friend, I am not trying to do this work for anyone else. This is my house. And your comments scream of a lack of home-as-a-system thinking. There is no elevation of mold, humidity, or contaminants in the home generally when all the systems are working together. Your HVAC does not have to fix problems in a home like this. I hope you get to work on one sometime, it’s pretty awesome.

Three things you need to live: 1. food 2. Water 3. Air. When we get healthy we change our eating habits and start eating healthy and drink filtered water. We add water filters like R.O. systems. We never really think about the air, even though we need air to breath but also it surrounds us so that we are comfortable. This makes so much sense to work hard on bringing the home full of clean fresh air. So we can breath better and be healthy, so we can feel comfortable and after it's all said and done, we actually save money by being efficient. Thanks for the video

Excellent video. Watched start to finish. Our duct work is original to the house, is all flex, has sider boxes, and dusts the house a lot. Unfortunately, most of the build shown is undoable (reasonably) in our case as we have a short attic space to work with (crests are 5 ft down spine of 2400sq/ft ranch style home) and I'd imagine to pull this off, the roof would have to come off. I've crawled around up there and everything is difficult, running CAT6, electrical, added insulation etc. Costs for a contractor to do this I'd imagine would approach what we payed for the house back in 2005. Still, I learned a lot and appreciate all the info. On new builds this is a great step-by-step almost tutorial. I wish there was a way to incorporate it into our 1967 built south Texas ranch. Our electric bills touch $500 this summer with the thermostat @ 78F. Brutal. Good luck with your business and channel.

Lstiiburek would say "ducts don't belong in the attic, they belong in the conditioned space of the house." Consider moving your duct work out of the attic, and instead run it along the top border of your rooms and hallways. You can disguise duct work into a new tray ceiling you also install at the same time. You can also disguise duct work into plant tray shelves made out 2"x10" and covered with sheet rock, giving your home the look of a transitional home. You can put high cubby-hole cabinets in a bedroom, similar to kitchen cabinets. Hide the ductwork in there. You can put long bench seats along your outside walls under windows, move your outlets to the base of the bench seat, and run the duct work under the bench. You can do this for adjacent bedrooms on the same side of a house--running bench seats in both bedrooms under their windows, and running a long duct from room-to-room, under the dual bench seats. Lots of ways to hide duct work that is inside the conditioned space of the house--where Lstiburek would want it. Hardest part will be insulating the ducts so they don't sweat and create moisture within your new constructed tray ceilings, cabinets, plant shelves, or window bench seats.

Great job Corbett! It takes a fair amount of skill to install a duct system well. Respect.

I really like the video and what you are doing and showing "working really hard to get the good things!!!". You have the knowledge and the experience to speak and doing what you are doing. It is, however, a bit harder to retrofit an old house with very little wiggle room. I hope you'll have a video on improve an existing old house ductwork. I love the idea of saying goodbye to flex duct. After seeing mice biting and making home inside a leftover flex in the garage, I decided to replace all newer flex return ducts in the attic with metal ones. It's a dauting task but like you said "good things" doesn't come easy. I would recommend you get a better drill. M12 is a more compact and light weight to lug around in tight spaces than this bulky cheapo one :).

Thanks for the great explanation in here. A quick question for @Home Performance though. Around 35:20 when you're discussing the dampers in the ducting, I see that you have a hole in the ducting where the "arm" of the damper sticks through and is stabilized on the side that doesn't have the handle. That seems like a decently large hole that isn't sealed. IS there a later step (not shown) where you cover that or seal it in some way?

Great video. Not sure exactly how I stumbled on you (probably your eighth video of yours I've binged watched). I think from one of Matt Risinger's video as a you tube suggestion. I'm a full time building consultant that does rental rehabs and new construction. Only general suggestion I would add that applies to new construction or substantial rehab (gut jobs) is to start with big to small on ducting, piping, hoses or electrical. Ifthe duct work started first, some of the head aches would have not been there and would have been completed a little quicker with a few less connections. But again, sometimes timing other contractors gets in the way of scheduling my own stuff, which is probably the case here. Great work!!!Great explanation!!!! Gonna to check out your other videos.

Intentional pressure imbalances. They keep the air moving in a constant, predictable way.

If you where to look down the flex duct you would see that where each of those straps are it creates a bump inside the duct. SO even taunt it has bumps internally. Its actually just the weight of the ductwork and the fact that the strap is only 1" to 2"s wide. But you can take a piece of card board from a box or whatever and cut it 12"ish wide, slide it between the duct and the strap. The cardboard then gives the strap a much wider "belly" for the ductwork and the "bump" is removed.....Not that you need it in your situation. Just a little trick that can be used sometimes when I see ducts that have bad "bumps" from strapping....Awesome video man.

Is it possible to do this without tearing out the entire system? it seems like it would be difficult to do leaving current duct in place. Thanks for any advice!

So this is phenomenal - thank you! I am building an ICF house with ICF flat roof in South Florida. Walls are 12 feet tall on the inside and no attic. I am planning to install sheet metal duct that is right below the ceiling, inside the house. My understanding is that I don't need to seal all the duct joints because the duct is inside the cooled area. If some cold air escapes before it hits the register it is not a big deal. Is my reasoning proper?

Awesome video! You are very good at explaining things. And it's nothing like hearing from someone who is doing the actual work on their own home. You didn't mention the worst part of flex duct. It can't be cleaned! Dust will get in, then any moisture gets in and mold will grow. Any holes in that wimpy plastic, and the fiberglass fills with mold. There are so many moldy HVAC ducts around. (Not in your house of course because you've designed and built it to prevent that!) But what is that black "heavier duty flex" you showed? I've never seen that.

That flex will last for 20 +years if properly installed and in a conditioned space also just a tip, use wider support straps to hold up that flex, not plumbing strap. There is nylon strap to support flex and if my memory serves 2 to 3 inches wide. But, very good job with a challenging install.👍

How did you go about finding. And choosing your system designer?

Wow. I live in a 111 yr old house and these modern houses and systems seem so complicated. Part of me wonders if we've overengineered and complicated things to the point where house designs are now like Mercedes engines where they are over tweaked for minor efficiency gains but at the cost of things like simplicity, cost efficiency, and serviceability. Older homes had many ways to increase comfort like very high ceilings to manage rising heat, simple ceiling fans, etc. Desire for pretty open design and a focus on central heating and air has made us build our homes into a pretty singular niche. Old russian houses were build around maintaining heat through a huge thermal mass, a giant stone fireplace with all rooms built around it. I'm not saying this "passive house" super efficient design is bad necessarily, but it does seem ultra complicated and tailored to mostly upper income level populations. Not everyone is an information sponge like us folks that suck youtube up for knowledge every day. I can't imagine the average person being able to service or maintain systems like these and even maybe half of HVAC service contractors. There's just a lot of considerations and extreme skill level involved that I dunno, I do feel like the simplicity and cost efficiency of a system and solution is just as important as the specs and ratings. Sorry long rambling thought train needed to dump a load. Not criticizing on the actual video or content.

I understand what you're saying, but we really can't go back to the way we used to do it which was super leaky and inefficient. The planet simply cannot survive with the amount of energy we waste doing it the old way. And we're also not going back to using the better materials like they used 100 years ago which could do things like tolerate moisture better. And frankly many of those old homes were not very comfortable. But you're right that we could stop trying to be lazy and expecting the house do all the work, and instead could be willing to do things like open and close shades, turn fans on and off. People need to become educated as to how homes work. And builder knowledge has a long way to go!

@@HomePerformance not rapture, anyone with a brain knows eventually the sun will expand and make the planet uninhabitable, we are heading towards our nearest galaxy, good chance we won’t survive that, and catastrophic events have happened throughout history, which is properly why recorded history only goes back 3,500 years BC. Not to mention all this worry about limited resources, when the population will peak around 2050, then it will start decreasing, it already is in China, flat in India. Yes I do everything I can to eliminate waste, and I’m an outdoors person that loves nature, I just have a problem with this panic about man’s influence, when there is so much that happens beyond our control. Seas rising, tectonic plates are moving, land sinks, rises, continents break up, come together. volcanoes, asteroids, etc. Yet never a mention of the good, the planet has actually become 20% greener with it warming up, and what is the ideal temperature of the planet? No one has an answer.

Did I read somewhere else you used chemlink m1 as the duct airtightness mastic?

Awesome video. You’re hired when we design our house lol

Awesome Pete, thanks- I’d be delighted to help you.

Flex duct is cheap and "easy". Thats why they like it. Along with duct board. Both of which are only 15year ( if i remember). Metal duct takes far more precision, building, sealing, and insulating. Its costlier in all ways. I recomend put something between the strap and the flex.. Spread out its contact area that tiny contact will split the fiberglass and potentially be a sweat point.

I have installed ducted heat pump for ground level open lounge/ family room 80 square meters 10 kv daikin system with 3 x 200 diffuser and have return on upper level ceiling is this right or I need return from ground level too . In morning when out side 5 degrees c inside 14 I set 23 and it takes 3 hours to reach 23 and expect to heat in 1 hour am I right

Crimpers >> use with the 3 blades to the inside of pipe.... Those reds are straight cut bulldogs.. get a pair of reds like the greens you have and you will love them.

I would have set the filter support for a 4" deep filter to start with and made a 2" spacer for the 2" deep filter.

well done

Thx Frank

While I sort of understand your concern, (and totally understand wanting more robust) with the flex ducting, wouldn't the fact that it's in a conditioned space, and protected from harsh exposure ensure that you'd easily get 20 + years of productive & safe use out of it? It's only conditioned filtered air.

Sure, but the metal ducts will last as long as the rest of the house. And our plan is to hand this down to our kids, who’ll hand it to their kids, etc.

Awesome, Can you do a video explaining how to calculate the duct size needed for each room? I'm lost.

@@HomePerformance Thanks man, I was unable to find that info in that video though. Is the size of the duct needed promotional to the volume flow rate? Sindenote; "you said if you have a lakefront lot that faces west with all your windows on that side......" haha hits very close to home.

Haha, happens to all of us sometimes. And yes, the duct size entirely depends on the Btuh and CFM needed in each location.

@@HomePerformance can you tell me how to find it; I have cfm needed at each point in the duct and btu for each room already. Just don''t know how to size my rectangular duct or where to find out how to do it. just do cfm/(some constant air speed) to ged a cross section size needed? if so what is the speed i should plug in?

Aha- you need Manual D. But I hope to have a training in a slightly better way to do it by next year. Too late for you I bet.

Thanks

adjustable elbows are convenient, i’d do a proper measure and non adjustable, make sure you seal the gores, and put a screw in middle gore once you have the angle you want

Wow, I wouldn't trust my measurement skills if I couldn't adjust during install, but I'm sure there are wizards out there who can do it.

i got a 4ton for 1300sqft thats 350ft per ton in southern Nevada easy 115 degree days, i aim to get 1600cfm and my filter is 20x20x1 side by side for a total of 20x40 filter return. i currently use the honeywell HD merv 11 filters but i think ill start using the 3m 1200 merv 11 because of the more surface area on the filter to help decrease static pressure if that doesnt help ill try to use 4in filter

Speaking of surface area, the thicker the filter the more you have [assuming pleated design]. I have used everything from 1" to 4" over the years in various commercial settings and... it would be SO nice if 3" became standard for houses - that would nest easily in standard framing for ease of construction or retrofit. Occasionally you see houses where the fan pulls so hard a brand new 20x30x1" filter behaves almost like it's loaded with dirt - owner spends more money changing those out at greater frequency than if they bought 4" which would make the same opening behave like it was 20x50 with a 1".

@@flinch622 ya i ended retrofitting a 4in filter in my duct opening so far so good, i haven't had any issues but the initial startup closes my bedroom door after that is works like normal been using it for 4months and i plan to push it to 6-8months instead of the 1 yr filter that they claim is doable

What do you think about UV lights that go in the duct work or by the air handler?

Not interested- they introduce chemical reactions that are unpredictable. Also, they don’t do everything they claim when air is actually moving past them.

What is that black flex duct called? I can't get anything to come up with a Google search

We'll hotrod it, don't worry Lee! Everything is custom everywhere, and it was the easiest way to place the filter box.

Ever did HVAC for the Agriculture industry. Vertical farms to be precise?

Scoops are really bad for downstream airflow. The 45 degree take off is a much better way to go. This has been proven on the bubble machine. Great system other than the scoops. I with everything had to be put in like this. It would eliminate so many problems in the field
