You're right! Thankfully, I never had a mentor like that. My old man taught me the "right" way to do things since I could hold a tool in my hand! He was/is a hardcore perfectionist and at times it made/makes him unpleasant to be around!! But, I am very grateful for his instruction because I am forever engrained with the "do it right or don't do it at all" mentality. I was very happy to find so many folks here on YT with that same ethic! I am always learning and always will be! Thanks!
you can use the freon only for that customer .i charge them for the removal seeing i get charged for the reclaimed freon when i take it back for recycling .i really don t think reusing old freon is a good idea you never know what shape its in ,burnt,moisture,mixed with air,ect.i always install new stuff ,
crazy is right... i had a fue more like that yesterday were the compressor was sweating but could not video because the homeowner was right there watching me .but not this bad .. the other 2 compressors were like 3 lbs total over charged for both .still enough to make the system strugle ..thanks for watching ray
Great video Steven! Overcharging seems to be one of the most common problems in this business. You can't really blame the "techs" when the boss tells them, "add freon till that big line feels cold".

would you have to use a recovery tank without that testo? sure does seem cheaper and quicker to get rid of all that extra gass that way. great video im learning alot
Steve I really appreciate you, I learned from you more than I learned at school I'm a new tech by the way ,and still learning, What position the service valve is on to recover the refrigerant that way? And is all hoses connected as normal ? I can really use your help sir
+steven lavimoniere Here's an example. I once installed 3 Copeland 7.5 hp 0760 compressors on a 12' open upright frozen meat case and they were all bad. Compressor number 4 worked normally. The first two compressors that I put in would go out on their internal protectors even though I was throttling the suction service valve and keeping the amp draw down. The third compressor ran like a top but pumped all of the oil out of the crankcase in about 30 minutes. It was a very efficient oil pumper. Bad piston rings I guess? That job really wore me out.
That unit was happy to see yah Steven!! I can't believe this stuff. Why is the question why? I've never got that lol lol.. Great Video on crazy stuff Steven!!! ::D
Steve, do you still feel like the Testo 570 gauges are the best bet for a good digital manifold? Have you encountered something you like more? I am thinking about getting the Testo, it does seem quite nice... all the info you need right at your fingertips.
Very interesting video, I have a question what if in the same situation but with the txv doing exactly the same dance above sub cooling that is @ 11~15 but with 1~3 superheat or less on R22, would you still look at the superheat or could you just look at sub cooling only and ignore superheat since its txv? Could over charge issue be here as well? Thanks this is very interesting learning video I have learned a lot here ! and still learning more everyday.Keep up the good job!
Hey Steve are you recovering from the discharge of the system while in operation? wouldnt that 180-190psig of pressure do harm to the recover unit during operation? i realize there meant for 410a, and have only recovered refrigerant while it's at ambient temperature (system off) much lower pressure. Just curious. good video.
Travis Willcox the high side while running has more pressure then the recovery tank so it goes right in no problem ,just becarefull not to take to much out .. because your dumping out liquid. so it can get away from you quickly .. then you have to reinstall refrigerant
steven lavimoniere OK. thanks for the prompt response Steve. You have quite the video library for both plumbing and HVAC. I've been watching you for a few weeks now. Keep up the great work :] and appreciate all the knowledge you share. -Travis.
I would not expect to see a low suction pressure with low super heat unless the airflow is not good .. If the conditioned space is warm the pressures should reflect a good load ...Looks like someone overcharged the unit to keep it from icing up during cooler weather.6 lbs is more than double on that unit
steven lavimoniereYes it was over charged ...I do not say other wise . I just think if the room was so warm the pressures would be little higher on a 90 degree day with the superheat and sub cooling in the ball park of course .I just see so much bad duct work out there ,but most people can hardly afford the service call ..let alone redesigning the ducts
I know that . There is not enough load getting to the unit . If you have a 65 degree back pressure with an eighty five degree room there's another problem
I always did industrial .for maybe 20 years with very few call backs . I started doing residential where everybody is an expert.All the complete crap installs I see. Where are these guys ?? hope they are not the experts
That poor compressor. I can't believe people leave units so over charged like that. The worse shape they leave it in the better you look when you get them running.
to buy refrigerent you need and epa licence .but that don t teach you how to charge a system the right way ,lot off people that have no clue out there making tons off work for me lol
Check out AC Service tech. He has the instructional videos on every hvac subject like how things work.Steve is a working man video youtuber. Hands on subjects.
Had a goodman 5 ton unit with a bad compressor. The owner wanted to replace the whole system. Pulled the refrigerant out 34.5 lbs came out. It was supposed to have 16.375 lbs. wow. Didn't know they could hold that much extra. I don't think they are going to use that guy anymore. Lol.
Murray Melander i have a recovery tank in truck when its full i take it in to the supply house and get another tank t,hey have it reclaimed and prossesed
Guys i just don't get. How in the heck are these hacks so grossly over charging these systems. ihad one this morning that was 9 lbs over, i guess they're why i have a job
I know this is a while off- but my reply is still relevant. I’m seeing the same thing- opening up evaporators and seeing the inflow side completely stopped up= lazy... they’re gassing it until it cools practically drowning these compressors- it’s pure laziness and lack of education. IMO
Pulling out excess refrigerant will also eliminate some of the oil. How do you know that the oil charge is not too low. That recovery bottle hides the amount of oil being removed from the system. I suspect the manifold set used by the original overcharge person may have been old and required replacement. There was likely a freezing problem during low ambient temperature. Overcharging can happen easily under these conditions, and the suction pressure may not appear that high on the gauge. I think many of you commenters are trying to be smart ass rather than understanding how this happens. Get that word hack out of your vocabulary.

+Arnold Navarro thanks for watching
Steve I really appreciate you, I learned from you more than I learned at school I'm a new tech by the way ,and still learning,
What position the service valve is on to recover the refrigerant that way?
And is all hoses connected as normal ?
I can really use your help sir
mikhaielj the pressure on the high side of system is higher then the tank pressure so you can push the refrigerant into the tank .. at will
What are some of strangest hvac or refrigeration problems that you have had to troubleshoot?
+Jim Gill lol to many to list
+steven lavimoniere Here's an example. I once installed 3 Copeland 7.5 hp 0760 compressors on a 12' open upright frozen meat case and they were all bad. Compressor number 4 worked normally.

Seems like this year i have seen more systems overcharged then anything else. Good old beer can cold right!
What is a good price to charge per pound when removing charge?
Great video. I just looked at two with the same problem. Used my new testo 550. I've been missing out not getting it sooner.
testo's are very nice ,,you will never look back to analog gauges
surprised the compressor wasn't damaged by flooding
Steve, do you still feel like the Testo 570 gauges are the best bet for a good digital manifold? Have you encountered something you like more? I am thinking about getting the Testo, it does seem quite nice... all the info you need right at your fingertips.
definitely over charged, looks likes you got the right S.H and evap temp. nice work
Very interesting video, I have a question what if in the same situation but with the txv doing exactly the same dance above sub cooling that is @ 11~15 but with 1~3 superheat or less on R22, would you still look at the superheat or could you just look at sub cooling only and ignore superheat since its txv? Could over charge issue be here as well? Thanks this is very interesting learning video I have learned a lot here ! and still learning more everyday.Keep up the good job!
it might be a loose txv bulb .check if its insulated also super heat should be like 10 .maybe your sub cool should be 9 or so
Thanks I think you are right regardless it should have some superheat.
great video, I was wondering if you measure wet bulb with your 560 testo, do you use a wireless thermometer or does it calculate it for you?
Ron White testo 570 does not measure wet bulb ,
Well done .Thank you for sharing .
Nice work Steve!! Just started watching your videos on youtube but you are one of the best techs I have seen. Are you in the Boston area?
i am 1 hour south of boston .
thanks for the compliment
Should my suction line temps should always be around 50 and liquid 95 or it depends on what , im learning how to use my sman

Travis Willcox i am not using a recovery unit ,i am using the condencer compressure to push out the r22 from the high side into a recovery tank
steven lavimoniere OK. thanks for the prompt response Steve. You have quite the video library for both plumbing and HVAC. I've been watching you for a few weeks now. Keep up the great work :] and appreciate all the knowledge you share. -Travis.

Brian Ellsworth it was way over charged
steven lavimoniereYes it was over charged ...I do not say other wise . I just think if the room was so warm the pressures would be little higher on a 90 degree day with the superheat and sub cooling in the ball park of course .I just see so much bad duct work out there ,but most people can hardly afford the service call ..let alone redesigning the ducts

So what is the LRA with 6lbs excess gas? LOL poor breakers.
6 pounds Holy crap!! I had 2 over charged today but nothing like that?
Gary Schumacher ya this one was bad
That poor compressor. I can't believe people leave units so over charged like that. The worse shape they leave it in the better you look when you get them running.
to buy refrigerent you need and epa licence .but that don t teach you how to charge a system the right way ,lot off people that have no clue out there making tons off work for me lol
Your videos convinced me to get them. Thanks
well you made a good choice ,testo is a good manifold
man towards the end that unit sounded much happier I don't see how the compressor did not blow with that much pressure in it.
well it tripped out on high pressure switch .. yes it was sounding better in the end ..
hey hows it going Steve quick question. do you recommend those testo 570 gauges? and do you have a video explaining how sub cool and super work?
Check out AC Service tech. He has the instructional videos on every hvac subject like how things work.Steve is a working man video youtuber. Hands on subjects.

wow thats a lot extra ,,,,crazy
That's one thing I've found with digital gauges, is that you can see quickly how overcharged a lot of these older units are.
Jay Curtis digital gauges are the way to go
What do you do with those 6 pounds of R-22?
Murray Melander i have a recovery tank in truck when its full i take it in to the supply house and get another tank t,hey have it reclaimed and prossesed
keep it in the recovery cylinder and wait till the cylinder is 80% full of r22. Then return it to the wholesaler.
Travis Willcox yes thats what i do ..
Steve what's opinion on them SMan gauges
KQP Twin i never used them
Ok
Guys i just don't get. How in the heck are these hacks so grossly over charging these systems. ihad one this morning that was 9 lbs over, i guess they're why i have a job
+Thomas Werts not sure why probley they do not know what there doing
I know this is a while off- but my reply is still relevant. I’m seeing the same thing- opening up evaporators and seeing the inflow side completely stopped up= lazy... they’re gassing it until it cools practically drowning these compressors- it’s pure laziness and lack of education. IMO

You would think the compressor would have died.
TheRueuhy not good to pump liquid
This is sickening 3lbs and more overcharged. What has the trade come to 🤷🏾♂️🤷🏾♂️
Another system 6 pounds overcharged? Just like the American Standard!
