Wow you outdid yourself with this one. I’ve been watching your videos for years because it’s always such good information but the illustration with the video was absolutely amazing.
As a new HVAC apprentice, this video has really helped me understand a great deal on how the system runs and what's required for system to operates properly I'm a month in as an apprentice and have learned more things these last few weeks on the job than I did in 2 years at my last job ! Things are slowly starting to make more sense each day and these videos help a lot to further cement and expand on my experience in the field
Ive watched a lot of hvac help videos, but this one tops them all in terms of how easily understood and helpful it is. Great visuals, good commentary, clear and right to the point and very thorough. I wish they'd all be like this
Wow. As a non technician myself I found this extremely helpful. A whole lot of mystery was lifted. I particularly liked the white dot moving through the wires. Remarkable explanation in a very short time. Well done!
In your first thermostat wiring, you showed the white going to W2 but later it showed going to W1 on the air handler board for the hear strips. Which one is correct?
Great presentation as always. Now a question. I wonder how many techs make sure that the insulation of the LV wires do not touch each other after coming out of the sheath going to their destination on a terminal block or component. I don't know the answer myself.
Hello and thank you for your channel long time watcher first time commenting. I wish I had this training when I was a young technician, I inspire a lot of young men that I can see they are good candidates I will be sharing this as a introduction to Hvac I am wanting to get more youngsters involved in the field. Thank you, hod bless
I’m working as an apartment maintenance technician and noticed these air handlers don’t have a circuit board. All these low voltage wires are wire nutted. Sucks that most of these videos don’t show this kind of example. But I get how it works thanks to these videos. Much appreciated 🙏
this is beautiful , lots of peoples are visual and seeing such a well done video deserves props . Can't wait for the troubleshooting and diagnostic one . this is now the go to.. :)
I got kind of confused here your diagram shows the white wire connected to W1 but you say W2? I have a Trane/American Standard relay board connected to my American standard ACCULINK Platinum 1050 Thermostat when the thermostat calls for electric (auxiliary) heat the relay board lights indicates that Y2 and W1 are energized when calling for auxiliary heat when the heat pump goes into defrost mode it energizes O Y2 and W1 in emergency heat mode it only Energizes W1, G, and E all stages indicated by a Green light beside each input on the relay board. When my HVAC contractor installed my system this is how they figured out how to wire everything up to the relay board by putting the thermostat in system test mode to see which lights lit up on the board depending on the call. Confuse the heck out of me because the thermostat only had 3 wire inputs B R and D that was used it had other inputs but they were for sensors like outdoor thermostats and such.
Also it is necessary to run 24 volt wires through metal flex conduit on the condenser if you have a pair of Boxers that like to chew up things like ANYTHING!!!

Hi, i just came across a very interesting topic on low voltage wiring, and was hoping that you or anyone out there could explain: how to ground a heat pump 24v transformer? OR explain, what is the "GROUND" on the low voltage side on the control circuit?
Hey, well dangit, you confused me there on the orange leg. Is 24V oncqll for colling? Or was the just for thw Rheem you had mentioned..is that yellow and orange snd red also and obviously green oenergized on heat pump mode?.
This is the kind of videos I’m looking for. I do commercial. I’m also still new at this. Love the simplicity of the way you teach in the video. Need more thanks
Just started my apprentice ship at 31 ......... have 8 years oilfield experience producing natural gas wells Anyways I just started watching these videos to help better understand what I'm being taught on the job and let me tell you , learning at the pace at which a season veteran of the trade works can be challenging these videos help fill in the information gaps that get lost in transmission
excellent material for a basic study of the electrical components of the system. May I ask what program did you use to create the electrical elements of the video? Thanks for you posts and videos.
This is one of the best videos I've ever watched! Thank you and I hope to see some of these style videos for supermarket refrigeration (Racks and Protocols).
I did want to poiint out one thing. You said the "dh" dehumidification terminal being energized brings the blower up to full speed? I believe its the opposite, to slow the blower speed down to aid on dehumidification while cooling with overshoot on
You know it's only a rendering because there are clearly labelled terminal blocks instead of dead rats tangled up in a web of spade lugs and wire nuts.
How does the dehum work? Does it cool and heat at same time? Is there a reheat coil? Does it over cool to reach dehum set point? Does it run at low speed?
Videos like this must be recommended to every HVAC instructor and every college in trade school for their students. I’m always constantly trying to convince automotive technicians who been in the business five or 10 years in drive ability in electrical who are thinking of changing trades to go over into HVAC or HVAC/R telling them they will get paid better the work is easier and the systems are so much simpler like working in the cars from the 1970s and 1980s.
