I’ve been a hvac engineer for 20+yrs now and found your videos while scrolling through TH-cam….so glad I did as I watch them all the time, wealth of knowledge and learning new things about plant I hadn’t worked on before. I tell my lads who work with me to watch them to learn from….the time and effort you have put in must be incredible to produce such detailed and informative videos…well done mate…keep it up..👏🏻
this is an incredible resource. i'm 19 and and just getting into the HVAC field and beside my mentor i don't really have any other source for information. i really appreciate the time and effort went into this especially in the diagrams and schematics designed, much easier to understand over someone trying to explain a specific system, part or unit.
Really pleased to hear these resources are being used to help young engineers. It can be difficult to get the hands on experience and exposure that's why we try to include as many models, photos and real life examples as possible. There's plenty more videos on the way!
Thank you very much for the video. I'm new to a HVAC system, always being doing Fire Protection and Water Supply System design, but my new job requires me to understand HVAC system and this helps me a lot. Thank you again and God bless you!!
I'm a new HVAC apprentice with a lot of mechanic experience, but I just wanted to say your videos are worth the time. Very thorough and knowledgeable. The software you used to narrate the systems is really cool. Keep up the good work brother. I'm liking and subscribing after this video. This is the 2nd video I watched and will continue to watch your content.
With all due respect, dude you need to be a lecturer in a university. You would be the most favourite teacher in the Mechanical Engineering Course Hands down! Best explanation of HVAC ever!
Thanks Raghav. I like to teach via youtube because then anyone in the world can learn as long as they have internet access, plus all our videos are free! university is expensive, limited to just a single class and usually not available online to relearn
Can't believe you share this invaluable product for free! We must pay for it expensive costs in university only for theories, without any visual explanation. Your solidworks design skill is admirable too. Thank you so much.
Absolutely it is worthy. but we have limitations in Iran for creating foreign pay-portal like paypal, visa, mastercard by the sanctions. These Days due the historical downfall of Iran currency(Persian Rial), the government prohibited exchanging foreign currencies. News are my witnesses. Hope you accept my apology.
I started to HVAC recently and this is one of the channel where more detailed explanation is provided. This video is perfect for any individual to learn HVAC. The channel and its videos help me a lot
Thank you so much for sharing your knowledge! This is so rare to come by. I’m in project coordination expected to know this, but no one takes the time to teach you and this is an amazing resource! Exactly what I needed. You give so much useful information, supported with the right images and real world examples. I don’t have words to express my gratitude. Thank you!
I am a beginner with only a few months doing tape and mastik. This helped me understand so much about HVAC that I did not have answered by my trainer/Boss
I had to pause the video at 18:00 minutes just to show appreciation for how much I've learned so far from your knowledge. I'm brand spankin' new to the HVAC world and I start technical school July 5th. I'm taking HVAC/R and PLC Systems. I hope to start some sort of basic work at least halfway through the school year if I get lucky. Can anyone give me any advice on starting off fresh? This is a major decision I've made but I also look at it as an investment for my life and career. I'm 27 and I need good career like this one. I would appreciate any advice from anyone out there in the field. Thank you so much for this video. New sub here.
Hey Bodega, really glad to hear the videos are helping you and that you've gone into HVAC. It'll definitely be an interesting career choice. My advice would be to ask everyone everything, if you see something and you don't know what it is and how it works then ask around until you find someone who does. Never be embarrassed to ask or to learn, no one was born with knowledge, it is something we acquire. If a service engineer comes in, shadow them and pester them so you know exactly what they are doing and why. Write down the model numbers of equipment and ask the manufacturers for their service guides. Lastly, don't over complicate things, large systems are complex but if you break each part down it becomes much more simple.

Hi Our air handling unit is not working on auto mode but its working in hand mode with fan air flow alarm and no vfd feedback if i start it in auto it will run and after few minutes its get trip
Having little to no experience in HVAC the explanations were simple and easy to follow along especially with the cursor movements used to point out exactly what Paul is talking about. A great instructor who is calm, informative and knowledgeable. Keep up it, I’ll be watching more videos soon.
BEST VIDEOS ON HVAC SYSTEM. I request you to please upload a video explaining the control devices used in HVAC .I want to know the nature of signal used to control the devices like actuator .How DDC controls the devices like actuators using dry contacts. What is the source of supply for actuator
Thanks for these videos. Just started as a project engineer at a mechanical insulation company and this has been so amazing for me to learn. FYI, the main job I work on is the MSG Sphere at the Las Vegas strip. Amazing place!
the work done on this video is astonishing. just imagine how much work that 3d model requires, and then how much work is required to make a video out of this...
Thank you so much for making all of these videos! I’m studying for my Architectural Registration Exam and these videos have been so helpful! I’ve shared your channel with all my friends!!
Found this video and also other videos on your channel. I just graduated from manufacturing background but trying my odds on building services. I knew just a little about HVAC system, and your videos made a great deal of help. Thanks for making such great videos, hope to see more soon! :)
Thank you very much for the video!!! It was very helpful to see the actual parts, because in college, most of the times we don't get to see actual components of an HVAC system.
Superb sir, salute from india I am instructor in government industrial training institute in ahmedabad for refrigeration & ac trade Thank you very much sir
please keep up the good work! I can see so much effort being put in to produce this clip and indeed, the others, which all are essentially a library of knowledge for a new graduate engineer to explore outside of the theoretical world.
Fantastic, thank you! I came here because I am interested to understand how an HVAC system works in a home, but this conceptual explanation worked great even though it is for commercial application. I would be interested in another video targeted towards residential, or at least a simple inclusion in the video description pointing out differences between residential and commercial systems. But yeah, awesome video.
Thank you for the amazing explanation, but there is something I can't understand at 41:32 -You pointed out expansion valves and refrigerant pipes within the AHU - shouldn't the refrigeration cycle and refrigerant just be in the chiller? Based on my understanding of your previous videos, AHUs, FCUs, and cooling towers just exchange heat between air and water, and only the chiller exchanges heat between the refrigerant and water. Why is this AHU different?
So the AHU might have either a water cooled heat exchanger (or hot water for heating) or they might have their own refrigeration system or be connected to a chiller system. There's lots of variations and reasons for choosing the systems design.
i love your video , sir please do a video on calculations to be done to recognize how much electricity or energy is required for chillers,boilers and ahu's for a specific floor.Thank you very much
At 36:14 you say you will get much greater efficiency in the heat exchanger if the fluid is moving against the force of gravity. Is that a mistake? I can see how that may make sense in a refrigerant evaporator or steam economizer, but I don't understand how gravity impacts the flow of single-phase water. Can you clarify?
thanks for the reply and sharing the link. Even though the AHU's here where I am at are built different, its the same concept. Thanks for sharing and I can't wait for other HVAC videos and related concepts.
The chamber where the returned air mix with the external air can be considered a mix chamber? I mean, both airs just meet together without any device in this chamber to somehow mix them?
I’ve been a hvac engineer for 20+yrs now and found your videos while scrolling through TH-cam….so glad I did as I watch them all the time, wealth of knowledge and learning new things about plant I hadn’t worked on before.

Thank you for the presentation. I have a question. Why frost protection temp sensors are digital inputs but other temperature sensors are analog?
The chamber where the returned air mix with the external air can be considered a mix chamber? I mean, both airs just meet together without any device in this chamber to somehow mix them?
Thanks for the information About Air conditioning system's I cleared all my doughts through this video, thanks alot
Very well explained with CAD model and actual photos and videos. Excellent work. Keep it up.
Thanks for putting in the effort for making these great videos.
Excellent piece of information. Great Work
This is amazing, videos n pictures and Models are clear as well as clear explainations, good work I suppose
This video is so useful , thank you for sharing with us.
Perfect analysis of a HVAC system. Very nice work. Well done. Is it possible to make a video about a basic control of this unit with BMS system?
great videos..i love them. Thanks for spending time for all of us..
I would be an even bigger fan if you could perhaps do a "building services troubleshooting video" for common HVAC issues and remedies.
what exactly would you like to see covered?
Thank you for all the time and work you put in. Great video!!!
Thank you for sharing this video on Chillers.
