Dave, You always do a first class job. I know Your customers really appreciate You. If the young techs will follow Your lead, they will do well.

[@myHVAClife]

Love watching your work. I do residential, but always learn new tricks from other areas of the trade. Going to try that flux trick. People get too serious about things, I like your easy going just go with the flow work style. I sweat the driers out as well. No need to have to put fittings together to make up for the pipe you lose when you cut them out. Just flow nitrogen and pull a good vacuum. Keep the puzzle pieces intact.

[@topher8634]

Compressors and vacuum pumps... Can't count the number of times my vacuum pump would turn over. Nothing like pulling up to a job and have oil pouring out the back of your van. I finally got smart and used a ratchet strap to secure it to the shelving.

[@mikejovanovic1645]

I'm not sure if you know this tech tip, but when I unsweat pipe from a compressor, I reuse the plugs from the new compressor on the old one. It only works if you unsweat the pipe. Just use a Phillips screw driver in the hole on the plug, and they push in pretty easy.

[@tbader20]

Some places (United Refrigeration, for example) typically won’t take warrantied compressors if they aren’t brazed closed. I had one splooge oil all over a rubber rooftop one time because I said, “Ahh, I’ll braze it at the van” and then I dropped it. Lol But the plug idea isn’t too bad if you’re chucking it into a customer’s dumpster anyway.

[@marknaravas318]

I’ve used that flux trick forever even when just brazing. Works like a charm!

[@jrramirez9117]

Keep up the videos nor-cal, doing the HVACR world a favor.

I have an El Cheapo bicycle rain poncho that I use at work , the good thing is that because it's light it can go over my regular work clothes , and it's cheap enough that if it reaps it's not the end of the world 👍

[@wdavem]

Good video! I once LONG ago went to a 'cardboard boat regatta' that featured the Exxon Valdez, complete with captain Hazelwood sporting a cardboard vest, cardboard captain's hat and a cardboard liquor bottle "XXX"; on the Connecticut river of all random places! And it rained! 🤣 At the end of the regatta, the Valdez wasn't sinking fast enough so the Captain kicked a hole in the bottom and I remember the hat and liquor bottle floating on the river!🤣🤣🤣 This would have been about 1990 when I was 10 years old, I'll never forget that. Too bad people don't know how to do that kind of thing anymore... or do we!?

[@life_behind_bars]

Hey Dave, great job as always. Mid 60's here in Iowa, so I'm getting the Harley out for a ride. A long motorcycle ride will help me cope with the anxiety your van organization gives me 😂😅. I'm considering a second channel dedicated to refrigeration work. I do a lot of work on Stoelting and electro freeze softserve machines, and I don't see much content on that. Anyway, thanks for sharing, my friend.

My trick is to add a little water into the flux and stir it up, loosens everything up.. Great video Dave.

I forgot you had that lil roll around. Its working out pretty nicely, i see. I got a nice little rain jacket for 21 on TEMU.

my navac recovery unit blew up the other day (coil popped) luckily still under warranty, took the refund on it and bought a fieldpiece recovery unit, loving it.

[@YuShudNoe]

Just be careful pinching the compressor ports on warranty compressors! I’ve seen some manufacturers require to install 2” stubs rather than pinching them off. 👍

[@topher8634]

Double the compressors, double the fun.

[@fredflintstone8048]

That jacket is amazing. I've never seen a jacket that could be used in multiple circumstances like that before.. Working and motorcycling! What will these geniuses come up with next?

[@hvacrnortheastern2110]

Dave just wait in till couple years you won’t be able even purchase 400 blend due to the GWP it’s going to cost company & customer $$$ on older equipment .The EPA is making the manufacturing to use low GWP refrigerant on all new equipment so in about 6 years all this refrigerant we are use too are going to be around hopefully l be retired by then counting the years .

So you’re done with the Smurf boner?! Who are you bro? You’ve changed man…😝😝 Is the vacuum pump just that much better or is it just not worth the time to swap out the hoses or were they not as advertised?

[@PSimonsen]

449 is the closest drop-in for 404, imho. R448 won't do freezers due to high compressor temperature, on the high side.

[@garypoplin4599]

23:02 - 26:15 Dude! I just realized that I’m spending _way_ too much time on brazing. You took barely over three minutes to braze all the joints on that compressor! Well done. And thanks for not snipping through it. Question: pulling from the high side only, how do you get all the vapor through the closed TEV from the low side?! Does the TEV have an internal equalizer? (Pardon the silly question: I’m new at this.)

[@NorCal-refrigeration]

I pulled both just high side first.

[@David-mg2im]

I have a question. Do you need to put the solenoid magnet while you pull a vacuum on this type of unit? Great video

[@philltafolla]

No as long as the evaporator fans are ON solenoid valve should be energized (open)

[@Leadmining44]

[@NorCal-refrigeration]

I have some but didn’t have 7/8”

[@mohamedrheem6854]

Switching from R404A to R448 - 449A you have to switch the TXV head first and then you can convert the Systems to the R448-449A.

[@throttlebottle5906]

lol, Dave discovers compressors work better with power plugged in. 🤣 classic

[@michaelmonfeli736]

448A similar to R22, not so much 404a. I/M dont have adjustable valve either

[@heavydiesel]

I've come to the conclusion at least for the stuff I work on that if you convert to R449A that you have to change the txv too, you can't just adjust it like with previous replacement refrigerants. What flux are you using? We only get the powder type here. Re gas prices, currently around $419 for a 26lb bottle/jug, but its going up 35.59% at the end of the month to about $568!!!! Plus disposable bottles are banned here so also have to pay bottle rental after a few months.

[@NorCal-refrigeration]

The flux stay-silv

[@sterlingarcher46]

Hey Dave what made you ditch the smurf boner hose , is it too much hassle to install ? I guess for larger circuits it must be worth it but for smaller stuff maybe it's overkill .

[@NorCal-refrigeration]

I have some 3/8 and 1/4 regular vacuum hoses I still use. The blue one was not working for me. I gave it to a viewer.

What is the difference between the transducer and a low pressure switch?

[@tbader20]

A transducer converts a pressure to a voltage reading for a digital controller to interpret (such as EEV pressure transducers on Beacon and Intelligen systems). A pressure switch is a mechanical switch that either opens or closes electric contacts at a low or high pressure event.

It might be a dump question but im a newbie, please don't roast me. I did not see you use the solenoid magnet tool on the solenoid coil. How do you recover and vacuum through out the entire system? Please explain.

[@AErefrigeration]

Not a dumb question

[@NorCal-refrigeration]

The solenoid is energized by the tstat at the evap coil. All open

[@manhpham8052]

Oh i see. I just got it confuse with the reversing valve on the heat pump because even when i have 24V to energize the coil but if when the system is low on refrigerant, there is not enough pressure differential to open the reversing valve. That why i thought the same principle will apply to the liquid line solenoid valve.

[@AErefrigeration]

Good answer

Put some water in that flux... and, why wouldn't you toss that comp, in the trash while you are there... I did this ref, ac, for forty years... did a lot of commercial chillers 25, 50, 100 ton... BofA downtown Tucson Az...
