I’m not an HVAC tech but wow…what great understanding to be able to explain this so well that a non expert understood it.

As a technical that is about to enter the world of commercial coming from 90% residential, I thank you for this very simple yet informative video

Hey David . Do you still the relay isolation relay information .

I do EMS for a living. Man I wish I could deal with techs like yourself. Might be a good chance you have called into my company. Phoenix Energy Technologies. We actually used to do Home Depot EMS but we no longer service them. Great video!!

Just got into commercial and I’m completely green when it comes to Ems and troubleshooting Ems problems.. these videos are a big help.. I dread Ems issues I can troubleshoot and fix a unit all day long but when Ems is involved I feel like a total idiot lol..

What about with a standalone Honeywell module? Still need Y2 on a single stage?

You're awesome! Fantastic video

Thanks

Nice job. Thanks so much. Give us more info.......

Great job and thank you for teaching us. Young man..😊

Hi, It would be awesome if you could explain how to replace the RTM for a T6. There are relays controlling Y1, Y2, Fan motors and my knowlage got to it limits there.

From now on, if I need help. On any unit, I'm going to refer to you. And I'm going to recommend you to other people. I've been doing thirty five years You know your shit And you explain it very well in detail. Guys have said that I should start a video. But after I saw yours, you put me to shame LO. L. Thank you so much.

Thank you so much for great info. Really appreciated

Very nice

Good refresher. Thank you, Sir.

THANKS HELP ME

5:40 and 14:51 - You’ll also notice here, guys, that the fins on all these coils are extremely thin. Notice the fins bend flat every time he punches his finger or fist into the coil. No heat will be exchanged at that exact point until they’re straightened back out!

I’ve not had a bad economizer to troubleshoot; but, now I’m confident I can efficiently service one if a problem arises. Great overal understanding and traps for new players!

Hey man, love your videos. I’ve even used some as teaching tools! Keep up the good work!

Great video

Change so many of those from being dirty and they eventually short out.

yes, those heat sinks are connected to the igbt's , they will definitely overheat and shut down, they die on inverter welders too if they arent maintained.

👍👍👍
