Same thing applies to air conditioning too. My boss was telling us of an issue with a mini split that was not cooling good. Some one had charged the system up thinking it was low charge but he found the evaporator coil (it was a cassette system) was dirty. Always check your evaporator fans and coil for proper air flow. Great catch.
Nice catch. After 30 plus years of working in this field I find myself being less critical of technicians that worked on equipment before me. As us old guys start retiring and there is no one to replace us, that means not enough techs and just as much work, and unfortunately that leads to overworked techs that are busting ass to get all the jobs done on their schedule for the day. That leads to misdiagnosed equipment, unfortunately. The customer definitely deserve better than that. Something has to be done to get the young guys and gals into the field because as it stands, we are a dieing breed.
Great point on new techs. Once the kids figure out there’s no free lunch 🥪 they will have to go to work. I also believe if you can have a shop that only dose VRV systems and your good at it. You can charge whatever you want. Mega bucks 💰sitting there.
@@NorCal-refrigeration It's the same here in Denmark. Not enough new "good" techs. But refrigeration is not easy. Had a customer last week, thay had a small reach -in, placed between a dishwasher and chips fryer. They had problems with ice on evap.
it's no surprise, because they want to sell new equipment and very often. no repairs for you or I. same for automotive/truck/bikes, they want you to buy a new one/trade in often and the cost is far too high! it's all headed for a great implosion still, whilst they twiddle their thumbs and suck more money from everything.
Such a great tip on marking those motor brackets . First time changing one of those I just dropped it and when I went to put it back in it took me an extra 15 min to get it aligned where it needs to go Learned my lesson that day
@@NorCal-refrigeration I started remounting the motor to the bracket itself a bunch of times then the bracket to the ceiling itself. Such a nightmare It’s super tight and difficult changing those too
I've pulled them before, then bashed my head repeatedly to get it lined back up. I scratched lines with screw driver, instead of marker. but anything that works is great.
Pulled 60lbs of R12 out of a milk tank once, had a 1hp Copeland style semi on it that sounded like the big end bearings had gone, amazingly it ran as sweet as a nut once I put about 10lbs R134a back in, suspect it had a blocked drier at some point and previous guy just kept dumping it in until the bubbles cleared in the sight glass.
A warm box is always fun.. oh wait.. wrong box.l😅😅😅. Good catch Brother Dave. They should of called the professional from the start. Nor Cal yet again is True to his craft. Stay safe and be well.
I’ve seen plenty enough of Dave’s videos. Even though you didn’t show it on camera, I’m sure you at least checked out that condenser coil also. No need to be called out in a week or so saying that it’s not keeping up and you were just here. But, as always, you rock brotha!!
Some fans runs backwards, when they die. Specially never EC ones. And it looks like they are running. Also something that can mess with you. But 20 oz over, is a lot.
How to charge a cap tube system, with out scale... first thing I noticed, suction line frosted back, either no evap air flow or over charged, so if there is air flow and evap is clean with good air flow, system is over charged, how to charge a cap tube system, charge till frost line appears on suction line, stop charging, release a little ref, till suction line pulls back to evap.... correct charge.... the suction line is-not the evap. it is the suction line... I use to do 1000s of ice boxes for ice companys up and down the river.... Az, Nev....
That’s the thing with small refrigeration equipment. It’s so easy to overcharge so best method what you did, pull charge, weigh back in and further diagnose. Same with ductless heat pumps. Covers your ass in the end
Excellent example for greenhorns! Slow down, not everything is low on refrigerant. Critically charged systems need to be recovered and weighed for accuracy.
This is why I love you bro!!! GOOD STUFF, making the rest of us better. You rock Dave. Also, I saw you fiddle with that Klein multi bit doohickey then opt for the straight forward sized tool which reinforces my thoughts that the silly multi bit is a tedious clustercuss. Am I wrong?
I keep one of those multi bits in my bag and use it pretty frequently with my little m12 impact for fan shrouds, compressor bolts and that kind of thing. Not everyday but it comes in handy and it’s smaller than the little ratchet set I used to carry
from my past viewing of those fans, they'll speed up after running a while, I think the oil in them thins out again/bearing come to life. but they're still failing and need replaced soon or one will eventually fail to start again.
I worked with a guy who ordered a whole new evaporator for a reach-in freezer with a dead door switch because he said the evap was plugged with oil and couldn't cool 😅
@@Eetsohaad That is really bad tech skills. Everyone have a 5 point list, that they check first. On every call.. condenser, fans, compressor, evap, refrigerant, signal from pressure swith/ thermostat. It's not that difficult.
Breaking news!!! Supertech saved a poor compressor that was almost killed by the previous technician 😂😂😂😂 that previous tech have that compressor working double.
Would a TD show that the fans aren’t properly working, and I ran into this with a cooler thought for sure it was the thermostat notice the fan just didn’t seem right. Replaced the Evp fan and it finally worked again like normal
those fans often speed up to about normal after running a short while. I think it thins the dried/gummed oil back out/bearings loosen. each longer off cycle/defrost they'll drag again. eventually it will not start anymore.
Great diag! Not to throw the other guy under the bus, but ... Just as Not every song needing more cowbell. Not ever refer system needs more freon. The 'super tech' gets to the root of the problem yet again.
Oil in the compressor will trap refrigerant. I did show in video but at zero I shake the compressor and get the gas to escape from the oil. So I pull longer to try and get it out
@@persimonsen8792 why would you reuse the gas on a system that small anyway? I say that, because who knows what the "other techs" have added/done. not worth the risk/headache.
Almost a “ malpractice “ suit🤦🏻. Same with mini splits, I don’t know why guys are so reluctant to start back at the beginning with a known fact and an accurate charge.

What about the fans ?
