When I got back in to this 6 yrs ago bought the Testo probe kit aand has served me well or so I thought until seeing your quick technique of equalizing pressures in the system thru the manifold. Old school ways still have their place in this new tech world!
For one thing, I'm trying to wrap my head around how you controlled the pump-down from you manifolds. Never saw that little trick before, pretty slick and easier than front-seating. Nice. Did I see that right?
There was a pandemic of techs in the company I work for who weren't vacuuming their open system repairs. My boss at the time had to replace TXVs almost everyday, or filter driers. They eventually fired most of them, once my boss became the service manager. It's annoying to know people think purging the system is the same as "vacuuming" it. That's like saying Goodman is "as good" as Trane. (Betcha those are the same people who don't vacuum the system). Great video as always Dave.
had a job to do a start up for fishing boat hold unit.customer decided to save some money by piping the storage area on boat.also decided to save on nitrogen for leak testing by using compressed air.well what a mess they made.moisture city.took some time to clean that up.moisture is refrigerations worst enemy.

Thanks for the heads up on that. 👍😎 re: Sheet Metal - When ever I see corners, I ALLWAYS , ALLWAYS , ALLWAYS Fold em over too. 👍 I'm kind of psycho about it. Been stuck so many times. It sucks. Awesome Tip ( Ftngot ) Awesome tip - Repurposing nitrogen. To blow out condenser. I Have Never Done that. But, I'm going to start doing it. I Get stuck in my ways Blowing out with co2 only. What a Great idea ! Who taught u that one ?
I've been in there in that situation, no stickers or label for the system. Yet we're not magician or crystal ball to guess what Freon (units working on) thanks Dave for making this video 👍🏽👍🏽👍🏽
Had moisture in a few supermarket racks had to heat up the valves with hot water as they would freeze up and chase it back to cores up at the rack. Put in high water cores and after a couple weeks of chasing it you could even get the indicator back to Dry.
Dave we are cut from the same cloth, I always put stuff back other wise at the end of the job you got everything except the spare tire on the roof lol. No wasted trips to the truck.
Great video so far Dave! I started calling my hose the Smurf boner on my video I just released but then decided to take that out just in case maybe I can get something from one of these manufacturers 😂. Heck every time we advertise their product we get nothing in return so why shouldn't we expect something.😂 Also I have the 250lb version regulator like you have, Makes brazing the right way so easy👍🏻👍🏻
To check solenoids to see if they actually are working. Put your amp clamp around the coil and check for amps. It will be open but it will show anyhow. I always keep an old bucket from cleaning towels. Never not have it for brazing.
Hey Dave, just a thought, given the head pressure and the moisture indicator I am wondering if you had un-condensibles in the system, last time I saw air in a system I had a really high head and moisture. I’ve been using mechanics trouble lights with LED bulbs for a long time, they never burn out and the “battery” never dies.... I still wet rag too. Fricken sheet metal, get a tetanus shot! Thanks.
Hey NorCal on those packing nuts if peeps would loosen them up a little before they cracks um open, them things would not leak . I recycle the nitro to man it's a killer idea, I got a cheap air tank blower nozzle and fitted it to my ref. hose and love it.
Good job, but my tip of the day would be to flare a drier and sight glass in. Then you don't have to drag the torches back on the roof next time you have moisture in the system.
@@NorCal-refrigeration Call me old school ( I learned from my father) but I always flare in driers on cases and walk-ins, just makes it easier and quicker to replace after pumping down to change a valve or fix a leak. I guess when your charging by the hour might as well make it take longer 😂😂🤣😂🤣... I always burn driers in on self contains obviously.
Dan Chapman I got used to brazing them in after the POE oil shizz hit in 1991 the shop I worked for had us braze them in. So it’s habit now. I really don’t mind how anyone dose it it’s all good. ❤️
@@NorCal-refrigeration Yup what ever works for u do it. 1980s I think of flared TXVs, way before my time but I still see them all the time. I would never flare a valve in unless just replacing it with what was there. I just like to make it easier the next time, chances are that Poe oil is full of moisture and it will take an oil change or a few filter drier changes to get it all out. But I don't think I wouldn't mess with it if it's running, my guess is it will be time for a new condensing unit soon don't think that pump is long for this world... Pretty cool what u and other guys on RUclips are doing for refrigeration and hvac, I wish it was around when I was first starting, good work. 👍
Are you going colour blind Dave, I always thought that moisture indicator in the sightglass showed yellow when there was moisture present lol. Phil from the UK.
Hey Dave great video! Question. How do you cross reference different compressor manufacturers if you have to replace one with a different one. Is there any play with the tonage of compressors when replacing them? Looking forward to part 2!!👍

I'll be watching this about 3 or 4 times just to glean all the information you have here. Very thorough. Thanks Dave!

Purging only “works” in supermarket refrigeration. I still pull a vacuum... 52 bucks an hour why not?

Old school trick if those txv heads had went bad, you can place a dime between the head and two rods to get by for the night.
Yep.
One of your best videos in my opinion.

Yea, I was hoping he would have mentioned if the drier was restricted. I always look forward to your videos. Good one...
Part 2 Dale tune in. 👍👍
Great video..the Smurf made me chuckle like a 7th grader 😆.. Good job very informative..

Just email the company’s see if they will send you stuff. It’s that easy.
@@NorCal-refrigeration any particular department to reach out to?
N.W. Ohio HVAC Videos I just tell them what I’m doing and they get me in right place. Fieldpiece you can call there great to work with.
No Taj Mahal mamma, cant wait for part two...next level oh yeah next level Molly
Good stuff, can't wait to see the vacuum.
Damn dude you really went all out on this one good shit.
Awesome tips learned a lot thanks dave
That’s great James

Excellent video, looking forward to part two. I think everyone subscribes to Steve Lav.
His library is priceless.
Boy, did I bust a gut when that smurf's face popped up on that screen lol. Great video, man, haha
😂😂😂🤣🤣🤣😂🤣😂🤣🦴
Next level 👍
nice i just bought that regulator...feeling good about the purchase now that an actual professional bought it to lol
I bought after I saw chuck from comfort plus heating and cooling use it. Great channel
Nor-Cal Refrigeration & H.V.A.C was not aware of his channel - thanks for the tip👍
Nastynasthat 2017 good stuff on there
Love it!! 👍👍👍 Maybe the drier was plugged, did you try blowing through it?
Of coarse I did. It was plugged. Stay tuned for part 2. 👍👍

Dan Chapman RUclips would of been nice back in the day. I sucked in 1987. 😂😂
Are you going colour blind Dave, I always thought that moisture indicator in the sightglass showed yellow when there was moisture present lol. Phil from the UK.
When they go past yellow to white You,re Really screwed ! Mega moisture !
@@OcRefrig I've never experienced that :-O lol
Hey Dave great video! Question. How do you cross reference different compressor manufacturers if you have to replace one with a different one. Is there any play with the tonage of compressors when replacing them?
Looking forward to part 2!!👍
The parts house will cross it for you. It’s there job. 👍👍
Dave you say system has moisture,when you recovery refrigerant ,it’s also recovery moisture into the tanks or both mixture? Thank
where are your gloves ? is it a leaker momma ?
Hope you got all your shots up to date Guru. How did the moisture enter the system if it wasn't the TXV nuts? Is there a leak in the evap?
No idea. But there is always a back story.
was that a 5 hour service call ? 😂
😂😂
I went and got a light like Steve also makes working in the dark basement or anywhere nice 👍
No dead battery the guy is a genius a real Hvac treasure 👍
Looks like Santa Cruz, you hiring? I will work in exchange for knowledge. I have experience in refrigerator sealed systems.
Never knew they had a filter dryer u can use when ur reclaiming the refrigerant into the pump
Protects your pump more than anything.
how much did you charge for this job?
Awesome! Great video.
Thanks for watching
How do u pull a triple vacuum?
When you put nitrogen through high side should the solenoid valve be energized in order to pass to the low side?
Yes. In this case the box was calling for cooling so it was energized.
You can use a magnet to draw the stem on the solenoid if applying power isn't an option. There are a few different products marketed for this purpose.
Hey question on 9:00 is that a metering device being controlled by that solenoid?
Just a liquid line solenoid
@@NorCal-refrigeration that restricts flow on the high side? How does that work compared to a typical cycle?
now I wait for the second part. IDC about being first. Know how the time goes with pulling on wet systems.
Dave how did you get started on your own.
Got my license and insurance and knocked on doors.
I tried using that reusable heat shield & it was 🗑 🗑🗑
YELLOW MEANS MOISTURE....
And When they go past yellow to white You,re Really screwed ! Mega moisture !
That viper wet rag is the bees and Ees
I need to get that stuff. 👍👍
I got some and have been using last couple jobs. Yes works great. 👍🏽
Bear Downs good to know. I’ll pick some up👍👍
if there no ground how is the fan running
208 or 240 volts. He needed 120 for the recovery, vacuum and light.
Hey Dave I have a small wet rag I can send to you if you like. I just don’t know how to get it to you. Let me know if you want it I’ll send it ASAP
It's greet.
Part 2 pls
Tomorrow 3:30 pacific time.
👍👍👍lmao
Smurf baby.
How Long till Part 2. I can't wait ! 🐸
I’ll post it tomorrow after work. 3:30 pacific time.
