Training part of Your app is not working. Can you fix that? I have to view it from computer. It’s not working on iPhone.

What if it’s a zoned system?

Freemasons...fallen angels......the whole lot that run this world.....this place is a dump.....none of this was ever necessary...

everyones a Freemason .....sheesh .......

All about the money! Probably Donald Trump is doing the change and all the money goes to him!!!! Fdjt!

WHY ???????? TRUMP DOGE THESE GUYS !!!!!!

Hi. I watched all 5 videos twice over (2x speed). Your videos had the best content and your filler info was very helpful. I crushes the exam as a result. Thanks for taking the time to put this all together

Man I think everyone got the chlorine issue but you spend way more time on fluorine than necessary for an EPA prep class. This isn’t promoted as a “Future Refrigerant” course and it’s long as it is. I do appreciate your delivery of the significant parts. Very informative.

Why can't other Africa country can't apply for the EPA training online let it this EPA certification be equal right to all the country because is required in my own country now Nigeria, I have try my best to apply for it online but I was restricted from applying. Please let it be open to all sir.

Outside of energy, the primary difference with inverter & non-inverter equipment is, Everything that uses an inverter is always great for sure until the inverter says I'm not well today and everything else locks up in fear or gets locked in delay. Non-inverter, I can usually add or Relay or 2 and suddenly the home gets cooling and alls great for me and you.

I use the Tez8 for many years now. It's a great pump but I recommend adding a vac tree to the provided valve intake assembly.

I'm surprised they didn't find and use an unusual pretty painted nitrogen bottle. Shows the realness, me liky!

🐂💩 SCAM!!!! 👎👎👎👎

I live in northern mn we get 30 deg below how many houses freeze up break water lines i am sure the home owner insurance will sue the contractor installed it every time that happens

How often do you need to check the sensor and how much is the sensor test kit and the inert gas for testing

A2L is going to be a disaster. And the tech and heating companies are gonna have to clean up the mess again!

This is so stupid. Lets put a combustable refrigerant in homes, there was understandable issues with r-22. r410a was and is fine, but this is just ignorant. i literally cannot believe we are doing this. agree with @rvrrocket2765 we are going backwards.

Globalist, Technocrats, Elite, love to programing our lives, instead they owns lots privates planes polluting the environment with chemical, no sun, lots diseases, peoples get sick, making Pfizer richer and other labs. Now we as Techs guys needs to replace all tools to satisfier they hungry for more money and screw whole industry. Meanwhile, India and China, backyards mini manufactures don't follow the environment health protocols. In Dubai and the Middle East still using a variety of refrigerants, including R22, R404A, R410A, R134a, R407C, and R507:.. Why should We change it???? and US, copping all the stupidly agenda from Europa, Japan, regarding A2L, R32, etc...Its looking to me that we are dummies, fools...only they do have a brain in the earth.

I recommend installing surge and power line monitoring on the AH, too. This is often not done, but those AHs are getting more complicated, and those ECM motors cost so much to replace.

Merry Christmas 🎅 🎄 ❤️

Junk!!!

I wonder if will detect farts😅.

Installing my first one today and boy oh boy we’re going backwards in the industry. PHUCK THE EPA, and the manufacturers bending over to let them ram it.

This A2L is going to be a nightmare. The sensors will go bad and kill the whole system.

These videos, the Esco preparatory manual, and top 20 things to know on the HVAC channel helped me pass all sections and get a Universal certification today. The free Esco 608 practice tests can help you identify the areas you need to study more.

Thanks for the videos.

Thanks for the videos. Easier to get through compared to just reading the Esco 608 preparatory manual and good supplemental learning. People just need to add A2L learning and practice tests. The videos are a few years old but most of the content still applies and they're free. It's not hard to find EPA updates for rule changes.

Goodman is a trash manufacturer who turns out trash equipment

this has been super helpful, thanks! looking forward to the rest of the parts.

What a bunch of unnecessary complicated crap. It doesn't work worth a crap. Just by pass the sensor and be done with it. Video totally sucked. Showed nothing, no wiring nothing.

Excellent video and demo board. I have a question.. Is the Dragonfly system ok/safe with a dual fuel heat pump using gas furnace backup? Please advise. Thank you.

45:06: So, Type III has rupture discs on the evaporator barrel, but Type II rupture discs are on the condensers? Also are they still considered rupture discs on Type II or rupture valves?

Around timestamp 25:30: Why would the refrigerant capacity on the nameplate differ from what was originally put in the equipment? Are the capacities of systems increased without updating the nameplate?

Glad I heard it running louder then some other

Where do you mount that dragonfly board to

You went to fast!

What are you talking about. Esco themselves provide practice test with real questions and answers.

I hooked up and got ac to work but cant get the heat to work, i by pass the dragonfly and furnace works perfect?

And what if the sensor fails/stuck closed? And what about lineset leaks? Will there be sensors for that? Both refrigerants are heavier than air and I fear attics filling with flammable gas with no way of knowing it until it’s too late. Mark my words, technicians will eventually do leak searches starting from the front door for gas and refrigerant before turning on any attic lights or bringing electrical equipment up to the attic, and will charge HO’s accordingly. I hope Homeowners can sue the federal government for such short sightedness fueled by greed masked by environmental protection

I understand what you guys are trying to show and achieve but I’m not sure I agree with the way it’s done. I’d like to see a more real life situation. And not have you spraying directly on the sensor. I’d like to see how good a job that sensor does in a down flow application. And have the “leak” be more realistic like a very tiny pinhole on the back lower side of the coil.

Helpful video thank you. Just have two questions. Would you need one of these for R 454B? And do you need install one of these with an air handler heat pump system?

I was wondering if a smoke generating machine could be used in these areas to help find the leak

I Want EPA license to Freeon my own unit. What section is required ?

What's up with all the ads? About every 2 minutes one was popping up. Very frustrating trying to listen when u get so many ads.

Great video thank you
