Would you be open to some consulting work?

This is where i started if anyone else is looking for explanations and needs a diagram to go with 7:37. Underrated video my man. Thank you!

Loving the videos. Would appreciate an update on the book? Availability? @thinkingmechanically

are you able to share your library? or show us how to make the fittings?

I really appreciate this video, thanks.

Hopefully a easy question. If you match a small house (600 sq ft, 4800 cu ft) which needs 75 CFM( at 1 ACH) with a small furnace 40,000(32,000) BTU which on low speed only goes down to approx. 750 CFM. What am I missing as the solution?

Do you think that using only 6 inch round duct is an acceptable practice? Or do you think it causes some rooms to have too much or too little airflow. Thanks

How about reducing trunk size from end to end. When would you reduce the size? Based on cfms needed?

You keep saying "our climate". "Our area". WHERE ARE YOU

Is there a version with sound?

Thank you ,

Thanks for all the info you share! Any update on the resource booklet website? Checked your recent videos and did not see an update, thank you.

🫵🏻💪

(Suff -ICE) lol jk but other than that i love the video haha very good info bud.

Awesome information! These calculations are not only easier than the Ductulators but also spot on. I did a room by room CoolCalc evaluation of my house for a good size addition/renovation and the BTU - CFM formula was 6 cfm differnet than the Man J #! I heard you mention in this or another of your videos that these docs/spreadsheets are available in Google Classroom. Is there a link somewhere? Thanks again!

Appreciate this video 🤜🤛

Come back to us!! These are some of the best vids around! I’d pay to keep them coming

I would love to get a copy of your book to help with bids for rehabbing my old ductwork. Will it be available ?

Chris, this is a great tutorial on duct sizing. I have done many manual D calculations as well. I agree, this method is much simpler, and I wish I would have come across it a long time ago. Especially when comparing it to one of my manual D calculations, it is right there with it. I think a duct table as you described at the end of the video would be a great tool and it would be a great resource in the book. Let me know when the book is available, I would be glad to purchase it. Also, if you have anything to add on reducing the supply trunk duct after branch takeoffs. Thank you for taking the time to put these videos together.

Is the book available either for free or purchase?

CAN WE DOWN LOAD YOUR DOCUMENT COST???

? This is hardly for Dummies . Start from the beginning.

great video, helped me a lot. thank you!

If only i could consult with you on my rough ins...your providing some great info my friend

in short shielding wire, is to prevent Induction of a current from and external source, Trane uses some 5 volt DC circuits, when installed near over head power lines the magnetic fields can induce a in correct voltage, micro and radio wave can do the same. i hope you get pair well your a excellent trainer.

the motor question, to day PSC ore ECM PSC Amps go down Ecm Amps go up till they hit a safety limit.

i am 20 minutes in, i only do residential, wanted to chime in, most zone controls can handle a call for heating and cooling at the same time, the logic built in satisfices the call for heating first then cooling, and this happens in 2 floors, up stairs is warm and mom living on the fist floor wants heat. in residential we don't call them dump zones we call them constant air flow registers, to lower the by pass need or over all pressure on a variable speed motor pocking a register near a front door foyer, or kitchen dinning room with slider/ French door, or even a utility room is a grate place to have supply leads that blow no matter which zone calls so long as there not near a thermostat or zone controller. love you video's recommend them please keep them coming.

I really liked that it was easy to follow easy to understand and great information. Got me thinking about the duckwork I put in, in the past.

for cooling I like to look at it as the ceiling is another source of heat so washing cold air to cool it and carry the hotter air away as the colder air falls will create a more comfortable room.

you deserve more comments, first discussion of this I've seen. clo. rate? met rate?

Thanks

Thanks for education. Those 4 books I need to study and we are in 2023 please advise

Are there any specific chapters to reading ?

Thank U , good info !!

is this document still available i cant seem to find it

Hey , do u have more videos like this for the other chapters ?

I appreciate ya man

where we can get the fittings or how we can make?

Do you have commercial troubleshooting and sequence of operation. Really enjoyed this video

thank you so much for making this videos and make the time to do it. I really think this was very helpful i hope you keep making more videos like this about plumbing layout. I would like to learn how to make fitting to scale like you did please make a video about that next time.

Don't forget about the acoustic insulation, need to increase the duct to suit the insulation.

Great content

Great video 👏👏👏🙏🙏 I'll try to help you get you subscribers up... every on else downfall is moving too fast for us newbies
