OIL OIL ALL OVER THE PLACE

[@stevenholmes3589]

I started my electrical apprenticeship about a year ago after HVAC install for 5 years. I always wanted to be a service tech but it never worked out that way. I watch your videos and still have dreams of being a good service tech. Your content is gold. You're a good tech.

[@The98deville]

Oil leaking like it was a BMW

[@arthouston7361]

Or a 4.0 L Jeep.

[@Blasterxp]

Cool comment! Really like it

[@stazeII]

Also doesn’t have any turn signals, so can confirm, BMW.

[@JoeCdaYT]

More like an any vehicle that has not been maintained well.

[@dashcamandy2242]

​@@arthouston7361 As the owner of a 4.0L Jeep, and as someone who has worked on several 4.0L Jeeps, you're not wrong. Although, by some miracle, mine doesn't leak a drop! Previous owner put over $1,000 into making sure it didn't leak before I bought it two years ago. It's not a question of "IF" it'll start leaking, it's a question of "WHEN" and "WHERE" - but at least for now, I have one of the extremely rare non-leaking Jeeps. I've gone and jinxed myself, haven't I?

[@ThePowerofElectricity]

For these systems an oil separator in the discharge line seems like an idea to make the compressors last longer... Have it separate out a good part of the trapped oil and link it back to the suction with a capillary tube and cut-off solenoid for the pump-down. Considering how much time you spent on just this service call, it's likely cheaper to install these than just call you every other year. But hey, if the customer doesn't want to do it, it's more money for you later. Win-win.

[@HVACRVIDEOS]

Yeah but to be fair it would likely plug up the return line because they don’t do good maintenance

[@ThePowerofElectricity]

@@HVACRVIDEOS That is a very valid concern. Any added part is another possible point of failure.

[@uzlonewolf]

Those all-in-one boxes/islands would probably be good ideas if they were designed as modules with repair in mind. One section has a problem? Just pull a few bolts and that section can be removed for easy repair or replacement. But of course that makes the initial purchase price much higher so they don't do it.

[@Paul-IE-Repairs]

when that solenoid to Tee Joint cooled it shrunk and pulled back, hopefully there is still enough engagement @11:31 mark

[@garypoplin4599]

12:07 - Yeah. The boss always gets the easy TEV!

[@JoeCdaYT]

A suggestion that I could make is to resolve the oil issue is to put a cap tube after the txv to the suction line after the sensing bulb. Make a p trap with the cap tube after the txv to let oil get trapped but still let a little refrigerant after it has cleared all the oil out. This is the engineering mind that I have going that says how to fix the issue. I have run into this same issue before with failed power heads even on box systems. More info for the other techs in the field to pickup on when they find things like this.

[@danjacobsen416]

I, like watching what I did for 25 years. Was big in restaurant refer, work. Retired/back disability

[@dbell41888]

Only 1 coil doing all the work for some time but only noticed when 2nd power head went out. In the mean time coils just an oil accumulator. Knew immediately the solonoid valve was good. I always changed power heads live. pump down raise tstat to de energize solonoid in and out. 43fc i think. Easy peasy. 😊

[@rustblade5021]

one of our guy's hand got burned when he was unsweating a condenser and oil caught fire and spewed a jet of flame, even though the system was at 0 psi... refrigerant can get trapped behind oil, that's why it sometimes "burps" doing recovery and the microns shoot way up. we now no longer unsweat compressors, dryers, evaporators or condensers

[@glenjones4404]

Frankenstein outdoor unit lol It needs a hundred oil traps as the pipe work falls down to the multitudes of evaps lol😂😂😂

[@terminator761]

A big issue might be, the txv entering on the bottom and the sucction leaving at the top. Back in trade school we talked about it because the refrigerent has to move up against gravity and the oil falls back inside and stays down, im pretty sure if enter from top end put a nice p trap in there it might fix the issue. But i know its a pain since you dont have any space in there

[@Marklopez362]

We take care of a Kairak rack for one of our customers. I’m dreading the day I have to make repairs like this in their extremely busy line. So far since I’ve been with this company (1.5 years) it’s dumped the charge 3 times from lines rubbing out. They refuse to do any maintenance.

[@VC-Toronto]

I'm amazed at the lack of food scraps in the reach in section!

[@CHOMAHOMA]

I have not finished it, but I ❤ this video. Great work. I also like the idea of using that wire brush for cleaning the copper before disassembling the component.

[@fw2222]

"We are cool" 😎 most cool statement

[@davidefinland6886]

Polishing the ...

[@R290s_biggest_fan]

There isn't enough refrigerant velocity through the txv when the powerhead is bad, traps the oil.

[@alext424]

Great video Chris! I really appreciate your explanations in the closing words. 👍🏻👍🏻👍🏻

[@HVACRVIDEOS]

Thanks

[@joshua.sookoor2025l]

OMG! So much oil coming out, that compressor is done for!Awesome video! Be careful working on these units!

[@Arides2010]

Out of curiosity: What kind of gaskets are in the solenoid valve you brazed in? The valves our company usually uses have rubber o-rings that get roasted if you do not cool the valve during brazing or disassemble it before hand… great video as always. Keep it up.

[@HVACRVIDEOS]

That valve is too small to really protect, just gotta go for it hot and fast and cool it afterwards

[@luisgarcia2863]

Like always great info Chris. Thanks from florida

[@HappilyHomicidalHooligan]

If the Restaurant doesn't want to lift the rack to do a proper repair, is it possible to use a thick epoxy resin to coat the floor of the rack instead? Use a thick enough Epoxy and it should flow into the holes and plug them up, then set into a strong plastic sheet sealing the rotten area away from any water coming from the rack area itself such as when you're cleaning it... That won't be cheap, but it should cost a HELL of a lot less than lifting the entire rack to replace the rotted sheet metal would...and it would have the benefit of being done while the rack is running too...

[@RT-qd8yl]

We've done this using flex seal, it's held up 5 years now.

[@Shade_Tree_Mechanic]

​@@RT-qd8yl Wow. Flex Seal FTW

[@keith_5584]

Get that system a hotdog for all that mustard!

What's this chris struck oil dude ya gonna be rich as heck 😂 lol

[@renzmathewsserit8115]

One of sensible comment at the last part of this video❤️

[@DelticEngine]

Awesome in-depth video, Chris, with great team work. You put a lot into it going through everything and covering the important details. It was one thing to see all that oil come oil which makes you feel sorry for the compressor, but it was quite another to see your new 'look' when it came to the closing commentary! Is compressor oil actually from the proverbial 'fountain of youth' (which would explain the high cost of compressor oil as well as why HVACRs never seem to get old or at least age much more slowly), or does it make your make your hair fall out (which would explain the lack of facial hair and cap)?

[@fshn76]

Holy oil Batman.

[@adamdomaciucet2105]

Oil separator, Chris... It would solve this, use either a piston with a pulsing solenoid or a small capillary with pump down cutoff solenoid. Catches something like 98% of the oil, which would not solve the problem but definitely delay the onset of the symptoms. Otherwise 10/10 vid.

[@Jilocasindragon]

You shaved! :D No, good job! Love seeing something that makes you guys go "Huhh.. interesting"

[@zekenzy6486]

Great Video. Nice work and Good Job. Thank you for sharing

[@manuelrichter4529]

Hi, one question or two questions, i'm a Service technichan from germany. First why is the txv in the bottom? Shouldn't the suctionline at the bottom? Because of oil trapping in the evaporator and the cross flow of heatexchanging Mediums? Greats from Germany

[@jtbiberdorf]

Doesn’t the oil coat the inside of the pipes and prevent heat transfer while the refrigerant still goes through the coil? I don’t think it traps refrigerant in the evaporator.

[@jefftrain68]

Thanks for the hat bro. Fits perfect.

[@jasontexter1721]

Discharge oil separator like they use in ultra low temp refrigeration is a fantastic idea if they're gonna do stupid stuff like having the suction on the top instead of the bottom

[@alejandrozometa1951]

Yeah but like on a real rack you need an oil separator oil differential valve and a oil reservoir

[@matth5309]

Would using the exhaust of the vacuum to blow all the water out work? That way you wouldn’t damage your vacuum.

[@ronwade2206]

I love it, grind...grind... Darn it! 😅

[@user-cz8do7xl8u]

What you could do is come onsite with a couple buckets of Flex Seal and just pour it all over the bottom of the rack. Why? I did it on a similar job... and it worked..

[@jasontexter1721]

I had a contractor install a dual evap in a walk in and they left the individual temp controls install so only one evap would run and rhe other would accumulate all the damn oil so id lose all the oil in the compressor. I had to twin them. Running a compressor ar half capacity with large line sets is a recipe for disaster

[@danpresson]

Awesome video great info

[@JW-me2po]

Those pan chillers are a nightmare! Drains constantly clog and fan motors burn out.

[@HVACRVIDEOS]

Funny I’ve got a call on one of those pan chillers freezing up at another store tomorrow

[@JW-me2po]

Oh those are especially fun, when the whole drain line freezes. Had to make a 3/8 hose out of vinyl tubing that I use to run hot water while snaking down drain line.

[@HVACRVIDEOS]

Yeah I do the same, I defrost the drain line while using a shop vac to remove the water first than the pan chiller gets defrosted last if it’s not already defrosted

[@rockercover]

Send that system straight to the hospital. (Serious infection).

[@alekmartinez3109]

Pumping a scroll compressor down to 2 psi is a no no.

No it’s dirty overheated Poe oil

[@I_am_Allan]

@@HVACRVIDEOS at first I thought it was Canola oil... then maybe 5W15 ... then settled on Mineral oil. Alas, I was wrong on all three counts.

[@SupremeRuleroftheWorld]

did not know land rover also made coolers.

[@RealWorldHVACR]

So looking by the setup looks like a P.F. Chang’s. We do work for them here in Chattanooga. They have almost identical setup with custom built stuff and condensing unit is in rack. Ended up 7/9 of their evaporation coils had leaks. We ended up going back with all new heat craft coils since somehow the coils couldn’t be sourced. Leaks were so bad we were going back every month to top off charge

[@taylorj9920]

They were sourcing those original coils from a vendor that was getting them custom specd and built in bulk orders for those coil assemblies they we're installing during their retrofit shutdowns

[@johnhammon703]

I hope you know the risks of brazing with those types of gloves on. You should be using leather and not something that can melt to your hand. Just FYI. Safety first.

What what what what are you saying? you've made mistakes? I've been doing this for over 40 years. I've never made one single mistake.

[@TheBlu04]

I don't understand how people can let their equipment get to such a terrible status, I know there's been worse but this is bad enough for a total replacement of the system (In my eyes at least)

[@JJ-Toreddie]

For some. All they see is money being spent. Repair is a fraction of the cost compared to replacement

[@stillthakoolest]

Build quality is just sad on these units. But then again customer doesnt want to pay for quality so true wont build anything decent and you end up fixing this crap.
