Greetings friend Bryan from Michigan.. yes I am still hanging in there for a few more months. So many changes in our industry related to environment can deter unsure, new comers as service. These short informative videos help remove any doubt that we service and installers can meet the new standards for safety and handling. Thank you and your willingness to make sure the industry is held to the highest ethics and knowledge for all of us. Kalos is my referral for all my Florida friends in your area.. Ft. Meyers, to the east coast, Miami, Daytona. Never stop learning. 👍
New tools, new requirements for transportation and storage, perhaps new certification needs. And I'll pay for that, my client will pay. Equipment will cost like a rocket.
So nobody has addressed the fact that the scroll hard lock and don’t release pressure until energized. I can’t vent the compressor and the line set at the same time. So how can I determine the condenser is purged when the nitro will vent the evaporation circuit and leave the refrigerant in the condenser?
Just make all hvac propane. Put the condenser and evaporator outside. Use a antifreeze loop to transfer to the air handler. Put the electrical controls in a sealed compartment. Problem solved. Propane is an exceptional refrigerant. Cheap and very efficient.
98, you are correct, it would be like the old Arkla gas air conditioners that had ammonia for refrigerant and glycol for the chiller.I guess I’m revealing my age . I’m sure it won’t happen because your idea makes too much sense and would be cost efficient. Anyone that reads this, let me know in the comments below, if you’ve ever worked on a gas air conditioner (?).
@@boby115 I remember them too. Not very successful around here. Very few people knew how to work on them. I never did have a call on one other than to clean the condenser.
So... You want to add another component thus increasing the cost? The biggest issue would be designing the proper heat exchanger... Although if it is sealed.. We could lower the pressures and drop the temp really really low to make up for the inefficiencies in transfer.
@@Wrecked3 , chiller technology has been around since 1922, invented by Willis Carrier. Can we make the technology better ? (Absolutely). Yes, things are getting more expensive and technology more complex . The difference in cost, i’m not sure anyone could predict at this time.
I'm sorry but small appliances are already exploding here in the U.S. and they want to add explosive refrigerants to big units. I recently had a unit blow its full charge in a high school classroom full of kids because the wiring from the factory was left loose and the vibration from the water source heat pump compressor wore through the wire and tried to weld itself to the copper line which blew a hole in it. The kids would be gone if this continues to be allowed. 20 plus lives are more important than the risk this would allow.
The amount of refrigerants I work with vs a refrigerator or a car (small closed circuits that are worked on much less) is vastly different. This is huge, every tech has accidentally dumped a line before but if it was explosive that's a whole different story. Also I would like to see how flammable these oils are.
With the GWP thing, we were discussing likelyhood of ammonia and CO2 coming into domestic appliances like high walls, even R290. R32 is just 410A without the fire retardent in it as we were told by the trainer, but i own an A2L reclaim pump, i havnt seen an A3 one since its not been in our scope of work, but one thing that scares me is we all need to read what we are working with and know enough about it, we dont want to be mixing these things together in reclaim cylinders, we would need to end up having multiple reclaim cylinders for the A1,A2 & A2L and of course the A3 as a minimum, ideally we would have a reclaim for each Refrigerant, which is fine for a larger company, what is the solution for the smaller ones…
I'd hate to see ammonia come into residential areas. I worked for a farm store out of high school and they filled anhydrous tanks for fertilizer, that stuff is POTENT. Even as much as a little puff of liquid was enough to either eat your skin or knock you out COLD. It took me a few months just to get used to the smell of the stuff from minor vapor leaks.
I thought the critical point of CO2 was too low to make it practical without a cascading system… But, I work on specialized data center equipment, so not very knowledgeable on the subject…
It's all very well telling people who aren't listening that they should ask themselves if they are licenced. When you can't get a sensible refrigerant, you just use Propane (and that's that). My advice would be to assume Propane, and if you have reason to think otherwise, maybe you can. From an industry perspective, I would say there should be an unlicensed but safe pathway. That has certainly been closed in the UK, and it has inevitable consequences. I can buy propane/butane mix in cans marked "R134a substitute". I'm not even sure what it is beyond "petroleum product", but it works and by all accounts it looks like it's quite popular.
Good morning sir I have media split type air cond. Indor unit working outside unit not working the display error is ( M E ) what is the problem thank you and have a nice day Sir…
I am a potential consumer looking to get a split AC/Heat pump (Mitsubishi or Daikin). Should I wait for the new A2L to be available in the US? If I go with existing will servicing 410A in 10 years plus be available and/or very expensive? Will there be better performance with A2L?
The industry needs to hurry up with the 32 or 454. I am not selling 410A systems to my customers. I will put a compressor in an R22 system first. The industry is hurting itself.
Talk about taking a step backward!?... I think it's good to keep flamables to staying warm and cooking (just saying,been out of sevice for a bit). I get the hydrocarbon thing. And new to me is CO2 refrigeration. And that sounds good, safe, not hazzard and use in chillers. To me it just seems to open 13:52 door for problems. Yes, propane for rv bee. Around for long time. Thanks, interesting video
Step by step. You see, they already created supply chain problems. Now we need to change our vacuum pumps and gauges( very expensive part of our tools). I guess we need a new certification.
Great video . This answered a lot of questions I had . It’s funny how people freak out about something new . Like when people said that 4G was going to melt your brain 🧠 lol
Great customers over time squeezed for more money due to the supply of x gas, the service industry squeezed to buy more tools to adapt, and manufactures demand more money to cover the cost of change, all to supposedly reduce the world temperature how much?
Any flammable substance immediately turns into an explosive once it picks up oxygen. The mixture ratio is 14.7 :1 This does not seem to be a problem for your house because you have insurance, don't you ?
Will we need additional certification for our EPA license ? ( I realize we need to be educated about the new refrigerants but do we need some type of extra certification card that is mandated ?).
@@drummersnare6276 , from what I understand you got a certification for your training which is great👍 but that is not a required license which would have a number indication . Please correct me if I’m wrong (you have a certification , not a required license registered with the EPA , like the 608 universal or 609 Auto & Truck ???).
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.
Exactly! Being a customer, I need to replace a 23 yr old R22 unit, but refuse to spend thousands for a unit that has the phase out/draw down R410A. I asked that's what is currently being sold.
@@threeftr3349 a local big box hvac company here in Las Vegas is offering huge discounts on all there new units installs . Hmm I wonder why ? They know what’s coming . I do hvac , go head and get the 410A system ! . It’s more energy efficient then R-22 . You’ll still get about 15 more years and I don’t see changes happening soon .
No choice. Runaway lawmakers created a runaway government that arbitrarily makes laws about things they have no information about outside of the lobbyists. Lobbyists even write legislation that is dictionary sized and is voted on without being able to be read beforehand. We had a constitutional republic. We now have a constitutional-corporate republic.
Thank you for this video
I’m the old guy in the room one of the major requirements for refrigerant was, it had to be non-flammable under normal conditions

I want r-22 to come back. It is more efficient and and the damn ozone will be fine.

Should be trying to go back down to low pressures with micro channel coils
as far as the paint wearing off goes, use a sharpie and write the blend on the top where it can't rub off.

It means you should call a professional.
What’s the model number of your outside unit?
The error is ME? Idk sounds like a user error to me 😎. You'd need to state the brand, M/N.
You need new installation. It will cost you $30k.
😂😂😂
When you bring the propane tank home. Do you set up the tank and grill in the living room?
GOOD STUFF
Government it's all about money 😂. DuPont ''patent'' it's already expired.
Refrigerant companies see the conversion tp r290 as a threat to their future sales, they are reacting by raising the refrigerant prices.
That is the main reason we can't use R290. It's the refrigerant manufacturers who lobby for exotic expensive refrigerants.
Let's Go Brandon! More exploding appliances coming to your home soon.
Too bad it’s been like this for a few years now this isn’t a political thing goof ball
Smart electric meters remotely catch the house on fire then blow up your ac system when you have been targeted for termination.
Yeah but we need to get rid of stoves you can’t make this stuff up lol

Hi how are can it possible to install a capillary tube or orifice in place of the expansion valve, and does the cooling efficiency decrease?
Yeah just braze in the proper compression fitting... And then recharge the system via superheat
When is this transition going to happen? As in, when is the switch to R32 and R454b going to happen for AC and heat pumps? (Edited)

At the present time, no. Subject to change, but the current EPA rules require you to keep up with new rules.
