[@rj.parker]

Probably the only guy on KZbin that finds and fixes leaks. And installs new dryers. Bravo!

[@NorCal-refrigeration]

thanks RJ

[@winstonwright3613]

I hope those people appreciate all you did. ALOT of Techs would have said "well... you need a new coil. There's a 6 month wait. I'll charge it up, call me when it's low again so I can bill you again to gas-and-go it."

[@arthurddockery5974]

At lunch time it gets hotter in kitchens. The help leave the freezer open to cool the kitchen. It’s called the 1 pm freeze up

[@NorCal-refrigeration]

Very true. See it all the time.

[@prettycureforever7102]

I hate seeing two condensing units right next to each other thats over heat time but meh

[@dant4802]

That AC unit next to your unit is really squeezed in there

[@davejohnsonnola1536]

Judging by the condition of the coil and inactivity of the fan, I'm guessing its a boat anchor.

[@alansotelo6472]

God bless you all

[@MikeB9771]

Sweet video, a little bit of everything in it including wildlife. This is one a lot of newbies need to watch, very educational. Thanks for the video.

[@danwittels5542]

She's a leaka mamma! Good to see you and Tippy back in the saddle rested and ready! 😆Excellent repair video!!! 🙂

[@johnbell6956]

Clumsy as I am I’d of had all those top shelf bottles under the evap on the floor, in pieces.

[@analogmoz]

Real-world repair. Great job!

[@jerryfrigeration]

You are the man. I always appreciate your videos. Thanks for sharing. I see the SunJoe made it back, you had another pressure washer that I did not like when you used it. Once again thank you

[@NorCal-refrigeration]

The rinse kit pro is good. It will be used again.

[@charlessolazzojr6767]

Dave, you make great videos, but to a trained eye, I picked up a ton more information in the little things you added while talking your thoughts as you went along, little stuff like that takes alot more energy to do while your filming and working at the same time. You cut and edited the process top notch. You packed this one up with a lot of learned method of process from your yrs of experience and I got your method on this paticular box. You have a alot of patience. I can watch this a couple more times and better nail down your process. I can see how deadly the H10 is, everyone wants convenience with the battery sniffers, but you can't match the H10 accuracy, trade off of not catching the minute leaks and a better breakdown result

[@sherwinalvarez7365]

Great video. Thinking about getting an H10. Seems great for small leaks. What would be great before i pull the trigger is a video on its maintenance, cost and how often.

[@NorCal-refrigeration]

Not much really

great job cal-man you went above and beyond

[@Eddy63]

Great production Super Dave ... That was a pretty good sized job and you gotter done ...

[@scottk0623]

Thanks for the great video. I hope you have better luck with those CPS hoses than I did. Same hoses I put on my 550’s last week. New installation and failed nitrogen test. 2 of the 3 ball valves leak, 8 lbs. in 35 minutes. I have had them new in the package for probably a year. Beware. I was impressed as how clean that box was.

[@NorCal-refrigeration]

I’ve had the cps hoses for 5 years now. Still working good only thing I don’t like is there long at the end and don’t fit in tight places

[@keepnitkool9042]

I finally picked up a h10 pro! Trying to learn how to properly use it

[@NorCal-refrigeration]

There the best

[@charlessolazzojr6767]

A better leakdown result and better repair on not loosing charge until you get the replacement coil. Thanks, I thought I was nxt to you durring your whole repair.

[@catherinelachance2239]

If getting your head behind an evaporator is challenging, a phone i selfie mode and a flashlight will work also.

[@RjsEpicAdventures]

I ruined a 3 set of husky channels in one day they suck not I have knipex and chennellock brand and they have performed amazing and lasted

[@NorCal-refrigeration]

Yes sir

[@bradb4620]

Is that a receiver in their as well? Very difficult to get a good subcool with a receiver..Im sure you do but make sure SH is good at evaporator before dialing in the SH at compressor. H10 is great. That coil outside looks sad, great detail from you.

[@stephenbullock-yn3vh]

Another happy customer great job dave

[@cameroncochran1824]

Another awesome video by NorCal Dave. I wanted to recommend that you install slick locks on your van. Super easy to install and makes breaking into it almost impossible. They make a kit that comes with both locks. Back and slider door 👍🏼 highly recommend. Very good insurance for your tools. Those tweakers be out there ! lol

[@MrJujubean]

Damn, could they have gotten that condenser any closer to that A/C unit? Lol

[@heavydiesel]

I like big bubbles and I cannot lie 🤣

[@NorCal-refrigeration]

😂😂😂😂🤘🤘

[@jimsergi]

recycling is super hack of the day

[@rocker8692]

Its a pretty sensitive science,alot has to be working just right.

[@chrisao1987]

That coil is good as new now

[@throttlebottle5906]

before watching: multiple offender and main issue low on gas leaking. now time to watch 🤣

[@sevagarmoudikian4639]

I like it the bottles are jiggling

[@andrewsimon5437]

Love the longer videos.

[@harrydickson4575]

Awesome job 👍👍👍

[@darrenblois6259]

That's a clean box, I'd eat there.

[@Oz_is_on_fire]

Recycled nitrogen! Super Tech tip of the day. You’re a zero waste enterprise Dave, should get a gubbmint kick back for that. Also: Rat Bones bro!

[@briancarlisi2224]

With all that damn regulations in Ca I’m stunned at all the shit work installations I see on your channel and your Ca counterpart Chris Stephen’s channel. How you keep your cool when you run your calls is to be commended as I would lose mine over some of the careless work done by others. Also if you can discuss how you go about checking for a leaking solenoid valve that would be greatly appreciated. Thanks Dave!

[@NorCal-refrigeration]

It’s a total shit show out there.

[@konstantinostsoukalas362]

Awesome job Dave. Love your vids

[@NorCal-refrigeration]

Thanks.

[@ariel3464]

Te felicito! Sos un gran técnico.

[@GlenS123]

Danfoss evaporator coils leak too

[@NorCal-refrigeration]

I was wondering 💭 I figured as much.

[@jasonjang9642]

May I ask you a question? I have a customer buffat Resturant ask me to fix ice cream display the Temperture only can go 4 degrees C. ( 39°F). I went n told him condenser coil is too dirty n much grease. I told him I need to chemical cleaning for $160 then to see if Temperture will coming down . Next day I went the temperature still not coming down n sign glass is bubbling. I told customer the refrigerant looks low. I will add few refrigerant till bubbling stop for $250. bubbling stopped but still not coming. I told customer that I will need to change Txv n dryer . Customer refuse to pay me for cleaning n add refrigerant. He said unit is not fixed. What did I do wrong? How to avoid this kind of situation? thank you GJR, LLC Jason

[@drodriguez394]

Dave, I know you get a million comments. Can you point me in the direction on determining target superheat when adjusting on txv? Is it based on med/low temp applications? Based on equipment? I work HVAC. I have dabbled on the refr side, I would like to learn more

[@Chris-uh3cm]

Wish I could see the TXV adjustment

[@IFIXCASTLES]

Vacation over I assume! Dust doesn't effect the leak detector? Before I retired I was talking with another tech. He wanted the part number for the cube guide stabilizer. He said that when they close the door on the ice bin too quickly it caused the cube guide to shift position. I retired before I could test his theory. Sounds possible. Anyone ????

[@BrettWae]

Where do you get that sparky thing you have there?

[@NorCal-refrigeration]

I bought it at RSD years ago.

[@jamierushing8811]

Hi bro from west Alabama love and peace

[@charlessolazzojr6767]

Dave, do you have magic-pak units at the University, or do you see any used in small apartment buildings. Do you do maintenance on the dorm apartment HVAC units.

[@shine-cg9uf]

🙏🇺🇸❄💪👍 great vid n information Thanks 👍🏼

[@nakiapringley5391]

What do you set your h10 to manual or auto?

[@jimsergi]

make a burrito with the find.

[@chrisbivens5410]

Nice job. I always do the nitro recycle blow out 👍. Is there a reason you don’t use the rubber tip on the h10? Does it sense better without it?

[@NorCal-refrigeration]

Yes I lost it. 😂😂😂

[@stephwaylonwells3218]

👍

[@JStorysuoertech]

Another very good training video for the guys just starting out. Great video brother!!

[@NorCal-refrigeration]

Thank you.

[@RP-mt6bp]

Thank you for your video. I have questions for learning purposes. After the 26:30 what else did you do before you started brazing? Up to this point, you have recovered the refrigerant and went straight to brazing on the evaporator coil? Did you open any line that the fumes (from brazing) would come out? I.e., remove the Schrader valve, if any. Obviously, you did not let the OFN run through the lines while brazing ... (because you had to replace the evaporator coil later on anyway). Is it not a concern that the oil in the refrigerant line would ignite and blow fire through the same area you are welding?

[@philltafolla]

Time for a Russell Coil 🤷🏻‍♂️. No heatcrap for me 😁🤭

[@NorCal-refrigeration]

Turbo air? You got the hook up?

[@johndeerefan725]

Never had an issue with Heatcraft for me, I worked in a Walk in Cooler with 6 Bohn Heatcraft coils from 2007 with no issues, only needed new motors but that was it. It also depends on where they're installed, doesn't matter if it's Russell or Heatcraft.

[@NorCal-refrigeration]

@@johndeerefan725 they all leak in restaurant application

[@philltafolla]

@@NorCal-refrigeration I used to 😁🫠🫣

[@philltafolla]

@@johndeerefan725 I never had issues with them obviously if they’re installed nowhere near acids , vinegar, dressings etc . Difference between Heatcraft and Russell is that Russell used thicker wall copper compared to Heatcraft. But I had better luck with Russell coils lately especially the ones where the Heatcraft ones were. To each it’s own . You keep using Heatcraft I’ll keep using Russell even Trenton or Turbo Air seem to last longer✌🏼 .

[@marjones69]

Great video as usual Dave, I just bought me an H10 and think it's gonna pay off with time...I noticed you use the manual setting, is there a reason?

[@NorCal-refrigeration]

I’ve always ran it it like. That’s all.

[@darksabatta]

I like manual better it doesn’t really keep auto resetting every time I’m getting near and I can lower manual mode to pinpoint the leaks it works every time for me I use auto when there is such a high concentration of refrigerant in the air

[@marjones69]

@@darksabatta got ya...I suppose with time I'll learn the tool as with everything...I have to fieldpiece and it has been very good to me but it would freak out a little sometimes, so now I can confirm with more certainty especially when you can't actually see the leak to bubble it.

[@darksabatta]

what are your thoughts of 448vs449?

Why super tech you didn't melt the ice first 🤔 lol
