Thanks for all the love guys. I'll be straight with you, I uploaded these videos then life got busy and to the backburner it went. I was pleasantly surprised to see so many views and subscribers when I remembered about this channel. I'll put some time in to answer your questions and start making some more videos.

Good video.. at least it gives an idea to people to see how much time is needed for people like me and millions of others need to design a duct system or entire HVAC system only to hear complaints about the pricing. There is a lot time need to design and build a material list to properly quote customers. This is the stuff that goes on behind the scenes at night when we don't get to spend time with our loved ones to make money

I just wanted to comment and say thank you for making this video. I've watched dozens of videos the last few days about this subject as I'm redoing some old ductwork in my home and adding a few new ducts as well. The calculations for reducing the trunk to increase pressure was very helpful.

This is an amazing explanation of how to design and HVAC ductwork system and how the reduction of the trunk size allows you to push more air to other rooms farther away from your system. Excellent!!!

Thank you so much for the video. There are so many videos on you tube but this one gave me the most knowledge on how to DIY my duct work.

I worked in an HVAC dept years ago doing this stuff. You have done an excellent job of explaining and re-educating me on this topic. Well done!

[kathrynpe]

Thank you, thank you, thank you. My all male coworkers are cool and all but only so helpful. This info isn’t a fly by tutorial or something that in passing one can quickly grasp.

But your video and my duct calculator will definitely be a gem moving ahead.

God bless you!

Sir this by far is the best video ever explained 👏 thank you so much 🙏

[elijahgoodman]

Excellent job filling in the blanks I've had designing a duct system. I've always known about keeping velocity high, but what I didn't know was any velocity under 600 fpm was the point you needed to downsize ductcto keep static up. Thanks alot, truly.

[TheAbdallah]

excellent job explaining everything in details. I'm a Mechanical engineer by the way and currently doing HVAC Service residential. I really enjoyed the Video. thanks a lot.

[Michael-fpso]

This is one of the best explanations on this topic I’ve found!👍 Good shit bro, preciate you!

[will_hunt_music]

Awesome tutorial and great detail! Thanks! Only thing that would have been nice to add is notes on where/how to put the return ducts

This is my favorite YouTube video.
Seriously.
I've probably watched it about 20 times so far, just trying to get this information embedded into my brain. I've watched COUNTLESS videos here on YouTube about Duct Design, Sizing Ductwork, Calculating CFMs, etc.
You name it.
But this video in particular, in regards to the specific information that I am looking for, has been the most informative.
Hands down.
(I graduated college 2yrs ago (for HVACR), and, although I have performed a few change-outs and NUMEROUS service calls, I feel like my next step to advancing as an HVAC Technician is to learn how to calculate heat loads and unit sizes, and sizing ductwork.)
Thank you so much, @teachmeeverything3344, for the time and consideration that you have taken out of your busy schedule to produce such wonderful content.
And thank you SO MUCH for not playing annoying rap or elevator music throughout the entire video. 😏

Dude, make the next one the cold air return! :-) Great Video.

[WarrenHenry]

Thank you for posting this. For laypeople like myself this is valuable information

[IADHDD]

One of the best videos I have watched. Very clear and easy to understand. I really enjoyed your video and I will watch it at least 10 times more lol

[amolbhagwat]

This video is amazing and is answering lot of my basic questions about duct work planning. 👏👏

Thanks so much. You clarify lots of questions. I will design my 3.5 TON ductworks for an AirBNB place with this helpful info. Thanks again.

[pastorlee]

Very, very informative! I now can feel totally comfortable designing my own. Thanks so MUCH!!!
