I wonder about the step the Schroeder cores were reinstalled. The system was under vacuum and the core tool has small gaps to let you slide the cores back and forth when reinserting. At this intense vacuum it should suck in air and moisture via that gap into the system. I believe it’s better to add refrigerant after the vacuum and then reinstall the cores. The positive pressure will only leak a de minimis amount outward. I think this suggested method will prevent moisture to become acid and ruin the compressor. Maybe there’s no way around it as replacing the hoses from vacuum to the refrigerant hoses may still leave an inch of headspace of air inside the core tools. I just don’t know how to remove that air pocket.
repair clinic is known to be helpful for the common DIY'er, but the vast majority of people do not own specialized HVAC refrigerant recovery equipment.
I’m planning to stand on the scale in my bathroom holding the empty recovery tank, and then stand on it again after recovering the 410a to see how much I recovered.
I bought alot of these tools even tho I'm a DiY'r , and having done so, the dual system setup at my house has been immortalized... and frequently help out fam & friends nearby. For science!

@@rmalanis13 No, the valve cores were removed in the first place to evacuate the system. Then after the vacuum pull they were reinstalled since they are needed for normal operation. They were installed with a vacuum still in the system no gas. Then after when you fill it with gas the vacuum rushes the freon inside the system since it wants pull it in versus the pressure of the tank pushing it in.
What’s the best was to reintroduce the refrigerant? I was told to add charge first and then add the schraders. I’m not sure if it really makes a difference.
So, what was the purpose of introducing Nitrogen into the low side service port while brazing in the Compressor? Did you actually think the nitrogen would actually flow backwards through the Compressor or be able to overcome the resistance of the valves in the Compressor? That step was worthless and a waste of nitrogen as it would flow in the low side port, thru the evaporator and out the high side port.
Replaced a compressor today. Unsure what is wrong. Old compressor was grounded - continuous with the chassis. New compressor is fine, but the breaker keeps tripping when the compressor attempts to kick on. Tried replacing the capacitor, the breaker, and the pigtails. New compressor has same rating as old. Should I try a hard start? My manager will have my nuts if I have to buy another.
Turns out it was an install error. My tech didn't blow out the lines with nitrogen. We blew out about 4 big pieces of shrapnel from the suction line. New comp must have sucked one in and died.@@mattpacktree92
This install will leak and cause high pressures because of oxygen condensables. He didn't take any care to protect the filter drier when brazing, to smacking the compressor to seat the plug, not fluxing the copper before brazing, not purging the gas before releasing it into the system. I'm a 30 year HVAC tech and I wouldn't recommend this. Be careful who you watch on RUclips. I would recommend AC Service Tech, not this guy.

I wish you had provided the link to where to purchase all the tools you use in this video . Including the recovery machine
Excellent! You did a Great job.

I installed Goodman many times my last install i have problems with pressure switch it took 3 times to replace pressure switch
Remove caps of course when changing compressor, install valves of course

@@Samlol23_drrichwait…so you already have everything BUT the scale???
What did he spray on the compressor?
I find the atmosphere recovers really well!
Recovery tank (red) of course
Wow that was so cool !!
This helped a lot

What’s the point of pulling a vacuum if u break the vacuum with air and not refrigerant ?
The vacuum was never broken by air since he had re-installed the valve core in a fully sealed system.
Agreed. Need to add some gas to break vacuum. Then install ports to keep the non condensables from getting in

To remove as much moisture as possible from the system. You close off your manifold to prevent any more air into the system after a vacuum

You'll have to disconnect the power wires and the whip

If it came out at the other end , why not ? Do you know why why we use nitroglycérine while brazing at first ?

@@Holydanyno sute
Plenty of extra copper slack Goodman gives you to braze in the new compressor almost like they know it won’t last
thx

you have an operating voltage(208,220,240) issue. check for bad wiring

@@joshyaash daaaaamn
@@joshyaash what were the pieces from, cutting the old lines?
not really sure. They were a little curved, like maybe they were part of the scroll from the inside of the compressor@@mattpacktree92
Refridgerator recovery machine of course
This unit requires over 90 ounces
You dont charge with liquid
Never ever ever use emory to clean a joint after the pipe is open in hvac. EVER.
Exactly, you clean it...before cutting it...
A look for jab ayudante técnico no tengo esperensia en el
Furnace power switch ofcourse
Mann did all this and the crappy brand new Copeland compressor was seized lol was so pissed
Attach vacuum hoses of course}
Attach t-connector of course}

Third hose
98% of the repairs are not made with all this tools.
That’s not a new compressor. Just saying…
Shut vaves
