After working in this field for a local company for a short time I grew to really respect a GOOD service technician.? It’s not an easy job! Great video 👍
I really enjoy your videos. I am currently doing a career change from a heavy haul truck driver to HVAC. I’m not going into it completely blind. I do have some knowledge of it and some schooling from 25 years ago. I am currently 54 years young and my goal is to help people that can’t afford to pay for repairs or service or replacement. Living in the southwest desert Air Conditioning is a requirement for life and some elderly especially just can’t afford to even maintain the equipment less replace. So watching your videos helps me in diagnosis and knowledge I just don’t have from not doing it full time. Thank you for sharing.
Hey Curtis when pulling a vacuum on an existing system you will see fluctuations in the Micron gage because there will be pockets of refrigerant trapped in the oil. Keep up the good work
Hey Curtis I typically don’t pull my vacuum through the true low port, it’s typically a 1/4” line. I prefer to pull through suction line and then put my micron gauge on discharge like you had it. I like the idea of press fittings for tight to reach or flame hazard areas but since you still have to get nitrogen out for most repairs I think I would prefer to just grab my torch and braze. But I can definitely see the advantages in some cases. As always great work Curtis.
I thought I was going to like those new press fittings, but each repair means less copper left coming out of the wall, or wherever. Now we have to add more tubing which makes one more failure point.
Fieldpiece should give you the option to get the gauges with the wireless pipe clamps, the wired ones hardly ever work in a decent size commercial unit, that rls drier is nice, I wish the regular ones came with that nice stub of copper to work with
You know that 90% rubbing alcohol will clean up the sharpie marks on you plastic fitting guide tool & make it look clean again. like your good honest work.
@@fernandobazan829a vacuum test is the equivalent of doing a 15 psi pressure test. 10 minutes is nowhere near long enough. However if you watched again he did a pressure test but judging by the video not really long enough to properly prove the system.. Heyho
5:23 - This is the reason you _must_ mark the tubing with the depth gauge every time you use the Rapid Locking System (or the Zoomlock knockoff) press fittings. You’ll be sure of a tight connection with every press.
I bought a Sauermann Si CA-130 with extra tubing. Best investment I ever made. I made out like a bandit, too; because TruTech Tools was running a special and I got a wireless printer with it. Now I have documentation of the reason I condemn any heat exchanger. Just because you can’t see a crack doesn’t mean it’s not spewing combustion gases into the space. This unit tells you every time!
Curtis, just out of curiosity, have you tried to pull a vacuum with two hoses and using your gauges for the micron gauge? I've pulled vacuums on systems under the age of 2000 below 700 microns. 1200 seems like there could still be quite a bit of non-condensibles in the unit. Love your videos though, always an avid watchers on those new uploads, learned a lot from you. Keep up the good work.
Do you like MO99? I've been using TDX20 (458A) with pretty good results. Last year was the very last year that I even tried to buy R22. Just ridiculously priced. Only issue that I have with TDX is that it's easy to overcharge the system. I weigh in roughly 80% of the R22 charge and then run the system. It doesn't take much to jump right over the superheat target and have too much refrigerant in the system. As always, nice job one that dinosaur!
You have your digital gauge set for R410A but you are using a blue cylinder which I believe maybe MO-99. Will the pressures be the same as R410A and MO-99?
Hi HVAC guy I would like to know how many super techs how old is cold in on that short vacuum probably have done the same thing I know I have so you got my support all the way care Curtis like to know how many comments you did get on that Florida
if you still have R22 but the system is really low do you have to recapture the R22 or can you just top it off with r438a? i mean the price for 438 is really not bad $15 but I am just wondering about the work required.
Curtis, what was the final number of microns when you shut the pump down? 1200? Interesting... I've had my Apion core removal leak after 3 uses. They did send me 4 sets of O rings to rebuild it. I could only pull a 1000 micron number. I then used my Yellow Jacket down to 400 microns.
What's going to happen is the pressfitting seal will fail and everyone will blame the fitting when it was your failure to follow proper installation instructions it will fail with in a year guaranteed due to torn oring and vibrations but the biggest failure will be the oring because it was cut by the bur on the tubing that should have been removed by proper fitting prep.
@@dmiestercommkitchentech3043 The fittings were very smooth and no burrs, I used Nylog around the tip and around the taper just slightly, and just a bit on the starting threads. 3 times it pulled down very fast to 225 microns, with the Shrader valves out. The next 2 zones it would only pull down to 1000 microns, then when I used the Yellow jacket tool, it worked down to 250 microns. I might have overtightened the fittings by hand, never with a wrench though. I did notice that when I exercised the valve on the Appion tool when under vacuum the Testo micron gauge would rise in vacuum.
The burr is where the tubing was cut it will always cause a edge that will and does damage the orings so no the prep was not done correctly if you don't believe me about the edge go and use a pair of tubing cutters and then take a precision screw driver and stick it inside the tubing and push out towards the end of the pipe and 9out10 times the tip will hit the edge and grab the bur now take that same piece of copper and wrap it with paper and then turn the pipe in the paper and 9out10 times the edge will cut thru the paper and that is what happens to the oring try it I dare you then change your comment because you are wrong
@@dmiestercommkitchentech3043 Every fitting was deburred and Nylog was used. I was talking about the schrader valve tool was leaking from the lever on the new Appion 5/16" valve. The system passed 250 PSI of nitrogen for 15 minutes.
According to the Second Annual Report of the European Commission, R-438A has a global warming potential (GWP) of 1,890. However, according to the Intergovernmental Panel on Climate Change (IPCC), R-438A has a 100 year GWP of 2264. So it's not going to be the saviour some think, to make matters worse it's got about a 9.5 degree temp glide.
@@PhilipNation-xm5lh yeah. They are making it hard on the technicians. We’re going to have to carry so many types of refrigerant. I already carry three sometimes four different kinds.
Removing the VCRT, assuming that the core is in place, I think isn't a good idea, and without wearing gloves, worse. I'm saying that for my own experience, I had a bad experience. Be sure, takes only seconds and save yours fingers. My humble opinion.
Curtis you did not ream out the tubing; all you did was clean the pipe then mark the depth the most important step was either skipped or not shown if it is not reamed out the oring will tear and fitting will fail prematurely; this is POOR PRACTICE dont get me wrong I enjoy watching your videos but this type of mistake gives RLS bad ratings
I don’t use oring fittings, but the orings are on the outside of the tubing ? So not reaming would very slightly restrict flow and give turbulence to the refrigerant
@philiphusain3923 yes the orings are outside the tubing but when the tubing is forced into the fitting and the oring slides over the edge or the burr the oring gets damaged by the edge cutting the oring not completely in two it only nicks a slit in the oring

Well you got her straight, That's all that matters. ''92, we can put that one in a museum. Nice work

I agree I learned you do a triple evac when that happens.
The new pro press fittings absolutely change the game ! No more brazing I mean in cases you have to . This is a game changer! 👍🏽
Compression fittings of the 80's were known to leak by the mid 90's if not sooner. The game doesn't change with freon leaks.

Good to see you keep the old unit running
That's a Expensive looking crimping tool Curtis, it will be interesting to see how it performs over the years 🤔 Au
Nice work as always Curtis. Another one brought back from the bone yard.
Excellent repair curtis
Thanks 👍
Great job Curtis she’s an oldie but still a goody thanks for the video

Time to learn
What's That "Pressing Pliers". Nice, but I like also the "old" way. This is a time savior . Sometimes a better optoin.😅
Good job
Thanks

I forget. Did you check the evap coil for leaks? How did you determine the leak was only on the outside unit?
Bro he's been doing hvac for a while, I doubt he misses something.
Dear Mrs O he pulled a vacuum and it held for more than 10 min that suggest to me that there is no leak or need too watch the video again?
@@juantehandonguerrero1809watching his videos he misses loads..the issue is he doesn't know either.😂

Heyho
I'm glad you got to finish it. You could not remove the extra piece and pick the bad Schrader out?
Did you debur 😊it’s all good just messing around
What do you think about the press tool and fitting fir the long run?
So far so good
5:23 - This is the reason you _must_ mark the tubing with the depth gauge every time you use the Rapid Locking System (or the Zoomlock knockoff) press fittings. You’ll be sure of a tight connection with every press.
Well you have the same customers I do. They don’t know how to change an air filter or clean the grille off.
Years ago when m099 came out we were trained to deduct 15% off the r22 total charge because of the density of m099.
What carbon monoxide/ gas detectors would you recommend for a residence ?

Yes, I’ve used my manifold. I just prefer to pull on one side and measure on the other.
great work tech , do you still use field piece vacuum?
Not at the moment

Haven’t tried TDX20. But M099 seems to be better about not going out on high pressure when in heat than some of the others I’ve used.
You have your digital gauge set for R410A but you are using a blue cylinder which I believe maybe MO-99. Will the pressures be the same as R410A and MO-99?
No. Closer to R-22. But, has its own PT Chart all by itself
Hi HVAC guy I would like to know how many super techs how old is cold in on that short vacuum probably have done the same thing I know I have so you got my support all the way care Curtis like to know how many comments you did get on that Florida
Is there some usual procedure/method for telling the next tech the new type of refrigerant?
put a label on it, which I did, or mark it with a sharpie
Thanks for sharing your nicely done video. If I understand this correctly you also converted the system from r22 to 438a. Is this correct?
Yes, correct
I do have a question which is better the micron on your guages or the hand held one your useing which is more accurate 😊
Why didn’t you put more insulation on the low side piping? Just wondering?
Curtis, what is saturation? Good repair.
The temperature at which it is evaporating in the coil.
if the indoor blower fan is running, it can effect ur micron reading
I didn't see using the wet bulb indoor temp to target the superheat? Is there a rule of thumb on what to target when charging?
😎👍

I hate the replacement refrigerants. MO99 and the lot. It does save the customer money but it just doesn’t have the capacity of good ole R22

@@AustinAirCo yup. In short, it sucks
I hate that we seem to be stuck changing refrigerants very, very often. R32 won't last long. You can bet on that.
@@PhilipNation-xm5lh yeah. They are making it hard on the technicians. We’re going to have to carry so many types of refrigerant. I already carry three sometimes four different kinds.
Or the thermodynamic performance of R22
With R32 head pressure we will be seeing evaporators leak all the time.
What is the price difference in the rls dryer
Drier is inexpensive add in the couplings, and it’s still relatively inexpensive
Nice 👍🏼 work as usual 😊😊
I"ve hear MO-99 doesn't cool well with a longer line set, longer than 25 feet. Is this true?
do you use 410a ?
Yes
audio very low got my volume high as it will go.
what is the part number of the large Milwaukee bag?
Not sure
need one that size for my milwaukee screwdrivers
