From my brain to your brain, thank you for this information explanation of stack effect.

When pointing out the true suction port, perhaps you could obscure what you are attempting explain a little bit more by more hand/elbow in the way and a more sad camera angle.

This was a good learning class.All the students was attentive,mannerable & respectful.#GreatJob!

Thanks

Is yellow jacket a good brand?

Great video as always. Really appreciate your knowledge in time ..quick question in this video you’re showing a female a female quarter inch fitting hooking to your micron gauge. I’ve been looking all over for this fitting but cannot find it. Is there a certain description for this fitting. thanks again. You guys do a great job educating us HVAC guys good thanks

Muchas gracias, if I understood correctly an E fuse is 3.5 amp?

9:45 so if return air is 80 degree and evaporator temperature is 65 the working temperature is 15. 15 degree below designed 35 degree temperature. And super heat is 25 and subcool is 10. I got too much refrigerant? 😂 I'm so lost. This is new carrier system with slab coil new ducts new plenum

Thanks!

Incredible explanation

Really like your presentation, but the music is unnecessary and very annoying.

excellent graphic for beginners like me.

Can someone link me to the app referred to as psycro degree f app

thanks alot its very useful and nice animation

Awesome

Great-Aswsome

Awesome

So, GWP because of CO2 being released into the atmosphere. Yet, where did the CO2 come from? The atmosphere? If it escapes a sealed system from a chemical compound called R410a, doesn't it go back into the atmosphere? Trees, through aspiration, convert CO2 into oxygen. However, everywhere one turns they see the trees are being cut down to build crappy, albeit, lucrative construction projects. I say plant more trees and keep R410a. Of course that might affect the profitability of Chemours and the politicians involved. Beware of loud and fast talking people who are quick to ridicule dissent. Eg: "What advice do you have for those who are new to using refrigerants?" Answer, " Haw, haw; that's a whole other topic, start by getting your license." In other words, "Piss Off !" It is corruption at its finest. The bigger the government, the smaller the citizen.

I am surprised you explained it correctly. Many folks run around saying hardstart kits reduce startup surge current magnitude. That is not true. Normal startup surge current lasts in the range of 0.4 seconds without a hardstart capacitor added. A hardstart capacitor increases the motor startup torque by getting the start winding current closer to 90 degrees phase shift from Run winding current. This drops the typical spin up surge current time period to about 0.2 seconds. Most clamp on amp meters average the surge current for about 0.4 seconds so a short burst, 0.2 second surge time period reads lower than actual. If you have a true hardstart condition on compressor, due to low AC voltage or long or small gauge AC wiring, the startup surge time will increase. Normally without a hardstart capactor, if spin up surge current time extends to near 1 second it is likely the compressor overcurrent/overtemp internal protection Klixon will pop open from overcurrent duration.

What does "flex by hand" mean in this stupid a$$ field.. should read a steady value between 500 to 1500 ohms as leads are flexed by hand, if not pick up coil is bad bad probably won't get an answer for a year or two but worth a shot Google ain't worth a crap you don't understand this type of language

thanks for clear presentation of the functioning

The best recovery unit I’ve used. Highly recommended 👍🏻

Capacitor gets power from what leg the compressor run is on .

what if running amps are very close to my RLA

Liked and subscribed, thanks.

My experience with that meter is I've purchased 2, the first one had a bearing issue on the dial, it wore out the plastic underneath the dial and would cause the dial to turn on by itself and run the battery down, the meter was just over a year old and i could not return it. i spoke with Truetech Tools and they acknowledged that Supco was aware of this issue, however they would not replace the dial. fast forward 2 years, i found out you could measure running amps under load with this meter so i decided to give it a try again, as it turn out, on the 2nd meter you could tell they improved the dial, it was more robust, however, the first time i use it for testing capacitors, it would read one time, then the next time it wouldn't give you anything, just all blanks on the app. Hs anyone else complained to you about this? I really wanted this meter to work for me, but dam, why cant they be consistent.

Dont understand how to remove nitrogen after purge is done

I can never get over how Americans don’t just use metric.. 14. Pressure?? No dude it’s 1…. 😅

If you have a Amrad dual cap with CPT will you connect the wire to CPT?

Louisiana🎉🎉🎉

#8. No limit on the amount of income that is subject to FICA withholding. If your taxable income is a million dollars you pay social security tax on a million dollars. Yes there will be tax cheating but even with that it will still solve the insolvency problem and I very short order.

Both men are excellent teachers & instructors.#GreatJob! #UEI Colleges.

Should hvac tech have experience on hvac fabrication?

Awesome! Journeyman electrician here. Ghost voltage can be very confusing while troubleshooting. Great job talking about low Z meter. Yup, If u got one it will answer your questions pretty quick. If not, have fun taking apart every plug in a house looking for some weird ground or short. Great vid!

In my gas fitter program (Canada) we call them switches. This is the first time I’m hearing them called contacts. All good. Ps. DO NOT test continuity while the relay is connected to a live circuit.

What about where a hard start was factory standard, such as Rheem 4ton with scroll compressors? They did not need this for "failing" compressor, so why include it if it wasn't deemed necessary?

No doubt a soft start on a MOTOR is beneficial. However on compressors does the slower start impact the ability for oils or lubricants to get where they need to be quick enough at startup?

There will be a lot of erroneous faults in the new systems and false leak detections, and that will end up killing older folks.

At least move the lizard corpse first! haha

Aj what you do is important.

THANKS HVAC school team Im a HVAC technician i learnt a lot from this channel.this is what I was expecting from you desperately.eventually its there thanks a lot fr that.i hope n wish u upload more videos on VRF commissioning and maintenance

Dude from Louisiana reminds me of someone who, it’s his way or the highway and he is always right and even when he’s wrong he’s just mistaken. He’s number one and everbody else is just bringing up the rear. 🤔

You literally skipped the most important part.

On an attic, please do not attach the condensate line to the emergency pan drain line. If you cant run them separately don't use a drain line on the emergency pan. Use a float switch.

5 days for a changeout na I’m good I’ll bank my 3g for 8 hrs.

In a attic just get the unit running first then finish up ductwork with cool attic

Another one on Friday it’s up on top of a large shelf in the garage. I’m just gonna disassemble it up there. Pull the coil out. Slide in the new one put them in line chase back on and rebuild it. Done deal😅❤🎉

Man, the drain line barely has any pitch. You be lucky to have an eighth of an inch per foot is about a half an inch from point a to point B.😮😅❤

Forget about the outside air and what about pulling in water lol😮😅❤

Could refrigent gone if there’s no leak at all in the system?
