Big fan of your channel. Your work day is a lot like mine. Working here in Ontario. You are a no BS straight to the point TH-cam tech and I appreciate that. No fancy bologna just straight to the nitty gritty. Keep it up !
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.
Tell JR I said Hello, I haven't seen him years! Scott, W/NORCAL COOLING & CALIBRATIONS... I bought an Elitech last month, good so far, it's my new beater EDC. My TESTO 550s is wearing too fast! My trick is to add a little water into the flux and stir it up, loosens everything up.. Great video Dave.
I haven’t seen any of your videos for some time Dave , it’s a breath of fresh air. I see you have got some new tools, the manifold, temperature meter and tool bag ( where’s tippins?) 😂
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.
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.
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 👍
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.
Klein makes a Great 6 in one With a code Remover. It also has a thread starter on the other side for jacked up threads. I like mine served me well for 3 years now.
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.
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.
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!?
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.)
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?
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 .
Pinch one off and seal it up... I think I speak for many.. we ALL have done it to get a job done 😅😂😅😂. Then I lost my coffee to the Shanahan comment... made my own Exxon Mobil Valdez all over my counter top..😅😂😅😂. Stay safe and be well Brother Dave
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.
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. 👍
Hey dave ya need to clean ya brazing tip dude haha nice work mate glad to c ya bs with all vacuum bs, we here in down under do the same mate,love ya videos keep em coming.will have to get over there 1 day have a beer .
cant you use R290+R170 gas to replace R404a , one of my friend used that on small fridge standing fridge and underbench linked to it as well. so he used 300gm of R290+R170 . i think R404a was approximately 600gm .. so you only need to use half of R404a amount.
Hi Dave, im from Australia, just wondering how you are finding R448a compared to r404a on coolroom applications. Is the performance better ? Is the head presser higher ? Is the suction lower compared to R404a ?
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 .
Hi Dave when you run nitrogen through unit where’s it venting doesn’t it pressurise when your brazing ? What flux do you use I’m new to this cheers adam
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?
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.
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.
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...

Hey bud i do racks now. R22 to 448A just oil chnage. 404A to r488A we change the powerheads on the TXV and the foodblack should stop
Double the compressors, double the fun.

448A similar to R22, not so much 404a. I/M dont have adjustable valve either
Hey Dave. Link for the rachet please?
amzn.to/49rCQdv
Thanx
449 is the closest drop-in for 404, imho. R448 won't do freezers due to high compressor temperature, on the high side.
Why dont you flow nitrogen while unsweating. I always do to be sure not to create soot in the pipes. Just curious
Hey dave ya need to clean ya brazing tip dude haha nice work mate glad to c ya bs with all vacuum bs, we here in down under do the same mate,love ya videos keep em coming.will have to get over there 1 day have a beer .
Most definitely
37:40 hack and mo would have been done by 9! I mean it would have been full of air and moisture...

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.

It’s more efficient for sure. Pressure are similar to R 22.
