This video has been so helpful in teaching me that I don't want to/can't do this myself.
Man you are an HVAC monster! Your directions are so clear and you take safety very serious. Excellent work.
My total cost was $385 ,....Thanks just replaced mine and followed your steps and it’s been a week and no problems, thanks again.
U did it your self
How much for gauges and vacuum pump?
Including tools?
Hey! Did it all work out in the end or what!?😅
Plus $1500 in tools lol
Thanks for great videos without blaring music, lengthy “branding” intro graphics and camera mugging. Great videos.
EXACTLY...So sick of videos with the music and all the dancing before and after.
I give u guys credit for knowing how to fix these units. I'm just a guy from the general public. I dont have any hvac schooling or experience. I have an interest in these kind of things. I appreciate ur help in getting ppl's air working again
I needed a refresh since i havent changed a compressor in years. Very straight to the point,no bullshit, exactly what i like! keep up the great work!
Wow just wanted to say watching your videos and a few others technicians videos have helped me out so much in the field. Your very thorough and easy to understand. Very good tech. Keep it up.
I love this video. you keep it simple. I've worked with techs that try way to hard. I agree with some of the post about you going into teaching. guys that are just starting need someone like you.
What a great video. I realized this was above my pay grade for the issue we're experiencing but I still enjoyed seeing the process the tech is HOPEFULLY gonna do today. Thanks so much for posting this.
I will never in my life attempt to do this but I found myself watching the whole video
Ditto on will never attempt, and no knowledge of air conditioning, but watched the whole thing so I could criticize and point out how he should have done it. Those facts make me a fully qualified youtube commenter.
I’m 15 and I’m highly considering getting into hvac
@@nathang.1744 At 15, you probably will not be hired in hvac, but the Hyundai automotive plant is hiring children for 10 hour shifts.
@@deconteesawyer5758 I don’t think Nathan G was expecting to get hired tomorrow. My interpretation of his comment was HVAC is a field he’s thinking about making into a career. Obviously, after he has the proper training, internships, shadowing, learning, more training, more learning, more apprentice level work alongside more veteran technicians, etc, etc. He likely knows he’ll need several more years of hard work and learning for low pay before he’ll actually be hired.
I doubt he stumbled across this video, watched it 3 times and now expects to be hired next week.
Who knows, I could be wrong.
@@holdway73 Most of us of in the built back better America of retirement age face more years of hard work and learning for low pay too. We don't expect to be able to survive on our devalued savings and pensions.
Who knows, we could be hired tomorrow.
Great Job! I watched this video while replacing my AC Compressor, and it worked perfectly! Thanks so much.
You’ve earned a sub, Sam. Been in the trades over 25 years and know a professional when I see one. You have a great channel and you are a good instructor!
what is the precaution before brazing or while brazing with nitrogen at so little pressure?
I thought you did an excellent job. You have the ability to instruct - that's hard to come by. Thanks.
Thank you. Sam for taking your time to help new technician like me your videos are great and helpful
Just wanto thank you and also add that is nice to see techs like ypur self ( have not seeing one) that still WILL do the repair and NOT tell the homeowner you NEED to replace the entire system,and then do it in a rush that will create issues, of course they will be on warranty but who wants to be in thw middle of summer waiting? I know many times is necessary and the only option but many the tech can do this, so thank you for been honest
This is one of the best hvac channel. Thank you
Very good job ! This video reminds me of when i did heating & ac for 2 years. Thats not alot but i learned alot during that time. Very professional. We changed out a bunch of units and a few compressors. He never used that gel always a wet rag. That gel looks like it does the job well. Great job !👍
Hi Sam, I like you got the new compressor exactly the same old one so you didn't have to modify anything and the job looks nice and neat. Thanks.
Always use a micron gauge when pulling a vacuum. When you use your gauges you have a potential for them to leak which will not allow you to pull down to the manufacturer recommended microns. Also put the micro gauge on the liquid line because it is the furthest point in the system which will allow a great vacuum for the whole system.
Gauge -30 mint vacom need must be fee al l guage fee systom vacuom --30 max om -20 .30 max om ..using systom
I would add that leaving valve cores out, micron gauge on either side and two-hose to pump. No refrigerant hoses need to be used at all. Yea, using the analog gauges isn't a best practice. He had a 100% prior to this, so now I give him a 95% on compressor install.
Very useful video, explanation slow, step by step, understandable, thank you so much!
Good info I’m a home appliance tech. I’ve done many compressors and over 700 LG compressors in 7years. So this will be simple brazing. HVAC work is similar. Just larger capacity. Wanted to make sure I’m on same right track
Thanks
Great job at explaining the proper steps on doing a change out, It shows that you take pride in your work, keep up the good work.
I appreciate the support from viewers like you 🙂
You are. Good, you should be teaching in school, I am a retired HVAC person👍

So you dont do a flush on the old condinser and line set to remove contaminated oil before installing the new compressor???
@@jamesmiller6990 the old compressor was still running and not burned out. New filter dryer and a good vacuum after installation would be fine.
I know how to do this, but I cant stop watching your videos!
AWESOME. Helpful and extremely understanding ble. You need to teach a course at a college
Thank you so much for sharing your knowledge. You are really good at this. I am now subscribing to your channel.
Excellent work! Very good teacher also.
Please come to Florida and replace my compressor, you do a excellent job.
Instead of sweating the old connection apart, just clean the area with sand cloth and cut the pipe gently with tubing cutters. Gives you a cleaner stranger bond as copper strength diminishes with excess heat. However sometimes you can’t get a small tubing cutter in position. Nice and thorough video! Good job!
Don't do what he is saying, pure bs sweating is the way to go if u cut it, that means you will have to add more pipe
been doing this for a LONG time. NO you 95% of the time DO NOT have to add pipe when you cut out a compressor and it is Highly recommended by compressor manufacturers to braze in clean pipe. cut all the way against the brazed joint the pipe will and can give the whole 1 inch to braze a clean part into the compressor.
@@luisaleman4008 ..... You clearly are not an experienced service tech. Been doing this for over 25 yrs and own an HVAC company for 18. This is the cleanest and best way to do it and No you will not have to add pipe to do it over 90% of the time.
@@luisaleman4008 if you cut it ,risk of clogging the compressor by copper vibs due to the cutting tube
If you sweat it it creates carbon inside the tube.
HVAC copper is annealed soft copper to a kind cracking at the brazed joint.
If you sweat it the copper will be hardened unless you anneal it.
Pick your poison.
I’ll be over here cutting and swaging while you’re dicking around sweating.
Very well done. Good clear directions.
I subscribed I loved the video. Thank you. Now I will check out the other videos you mentioned.
I can only "DITTO" what others have already stated! One of the best instructional videos I've come across - very informative, very easy to understand, good camera work, even emphasis on SAFETY! Good on ya! Would also have liked to see the actual brazing technique.
Question: did you have the line set isolated when running nitrogen through the compressor brazing points - or did you allow it to fill the system? Seems like you would waste a lot of Nitrogen if you did not isolate.
Thanks - GREAT JOB!
Fantastic video with so much good information. Many thanks!
good job.
thanks for taking your time to explain.... subbed
I did enjoy watching this video. Thanks and waiting to see more useful videos from your
Great job.....one of the best I have seen to date.
Thanks for sharing your knowledge on this.
Awesome video. I've learned a lot. The only suggestion I could make is to also use nitrogen when you're un-brazing the old compressor out.
Great video, about 1 min in I knew this was not a job I would be doing myself 😂
Good work.. well explained you're awesome you are a real tech thanks for your time
No problem thank you for watching I appreciate it! :)
I liked your technique. Thank you much it is helpful clip.
Nice presentation and points...Thanks!
Good video, I’d invest in better gauges where you can use phone or tablet, it’s great having all the information stored stored, pressure test, vacuum, start up numbers, good for the warranty, and customers that may question something.
Love this great teacher
Just found your channel, I’m really liking your videos!! Thanks.
glad i came across your page right to the point and good proper installs subbed upload more ill like em and watch em thanks boss.
you should of added the refrigerant at the end though.
Thanks for the video! I’m In school for HVAC/R and I gotta admit you taught me more then the school 😂
Honestly alot of guys I know who went to school tell me that school is good to learn how to read controls and schematics... however when your in the field... you learn by experience and troubleshooting with your hands. Thank you for your input 🙂
That is true dude! Most of us learn better hands on then what a book tells us. But with schematics and blueprints then yeah school comes in handy.
“Switching out compressors and the importance of wet rags” lol 👍
Good job amigo, thank you for the video and the info. Have a nice day.
Appreciate the feedback friend! 😁
Good Video Sam
What are the more common bolt sizes for residential compressors
Big Thanks for removing the mystery👋👋
Wow thank you for this video. Very informative 🎉
Those king valves got the bukaki treatment
Thanks,,,,Great Info video
Very informative video.
Great video! Thanks!
very good video great explanations greetings
Hi Thanks for your fantastic video. Would you please tell me how you purge the system when you want to change the compressor? Where do you install the nitrogen inlet? and how it can be flowed while the compressor discharge valve is close? I mean there is no way for nitrogen flow through the compressor and it will be blocked inside the compressor?
Great video. Thanks
Great video nice work!
Sam!!!!!! You rock!!!! Paying someone to do this and want to make sure they do it right
How much?
Awesome job thank you so much
Nice...a lot of help
Hi. Thanks for cool video. Question. With king valves closed how are you putting nitrogen to brazing connections at the compressor?
Pretty straight forward, semi easy job, the hardest part is brazing the lines. If your a DIY, can you call out an hvac guy to evacuate the system so you can work on it? And then have them come back and service it when finished?
Very nice video!
Great video
Watched three videos already. I hope you make videos again.
hi mate good job , do you think will be a good idea to clean the circuit(liquide line and suction line) with netrogene
before you charge the system . thanks
Was just quoted $2,600 parts & labor to replace my 2018 unit’s LG compressor.
Very thorough
Great video thanks
EXCELLENT Video....Thanks for Sharing.
QUESTION: Bout how much time should it take a PROFESSIONAL to change a compressor like this?
Did you check whether a filter drier was installed inside near the evaporator before adding one outside?
I’m just curious I didn’t see it in the video do you run nitrogen when unsweating the copper lines from the bad compressor
Sam can you come and do mine please? Great Video Great job! Your hired.
Filter drier is the last component that should be installed. It’s taking on moisture while your messing with the compressor. Good job
Nice work
Curious to know why you removed the 5-2-1?
Hi, after replacing compressor do you open both suction line and liquid line service valves when doing vacuuming? Thanks
would've loved to see the soldering techniques but great video sir
What kind of soldering rod you were using ? brand and model, thanks.
One thing u should probably add is sub cooling and super heat and also seeing the data plate on the unit but otherwise it’s good
great video thanks for the info
Hi just an inquiry, which is economical? Change just the compressor or change the whole heat pump condensing Unit? Thanks
I purchased a Goodman 30,000 BTU split system. The compressor unit like this one is outside and the copper lines run to an A coil inside the furnace.
When I purchased it they said it came with a 10 year warranty.
It is only 8 years old and has stopped blowing clod air
It is blowing hot air.
I don't know what is wrong
I moved 6 years ago, I have a modular home and the unit came with me and has not given any trouble for 6 years.
Will the warranty still be in effect even though I moved and how do I go about contacting Goodman to have the warranty honored and have the compressor replaced if that's what is wrong ?
The fan on the outside unit is spinning like it always does but I'm not sure if the compressor is actually working
I have a set of gauges and if I hook up to the high side and low side what should I be looking for in the way of reading to tell me if the compressor is not working ?
Would a hard start capacitor make any difference ?
I did replace the capacitor 4 years ago with the exact same model and that was the only issue I've ever had with it
I'm really happy with the unit and if I can get even the compressor paid for and have to pay for the labor I would be satisfied with that
If I have to buy a new compressor what should I expect to spend and what should I expect to spend for the labor to replace it ?
Thanks for your help

I see that you retrofit R22 with NU22B. How did it go? Were you able to tune the system? Was there any temp glide? How about the SC and SH levels and did you also tune/adjust the TXV? I'm thinking about retrofitting it on my R22 System, but not comfortable doing it. Thanks.
Filter drier placement.... Did you check inside by Evap?
I install mine inside.
Thx good video
Did you replaced the dry filter as well?
When you purge with nitrogen before brazing compressor line, where does the flow of the nitrogen go? I would not expect there to be a path through the compressor right?
Why you didn't do a leaktesting procedure via bubble test?
Great video. Very helpful. As a new technician I would like some clarification..At what point do you use the nitrogen. I noticed you did not use it when removing the compressor but used it for installing the new one. Thanks for your help.
I believe you want an nitro in the system before you start brazing in the new compressor. The purpose of nitro is to prevent oxidation inside the pipes.
Most techs will just cut the pipes off first close to valves depending on if theres extra play to clean the cuts and then put them back in valves to be re grazed while running nitrogen through the pipes at 3psi to stop oxidation from forming in n out of pipe which can cause damage to the compressor and also clog the screen in a txv etc blablabla after brazing is all done then you fill nitrogen in system to leak test after that put vacuum on n let it pump down and remove moisture n any lil dust debris and then let it all hold in vacuum to test for any leaks while it's in a vacuum if no leaks then bam feed system refrigerant process
Brazed not grazed
Hi I have a question , how much it coast in today 2022 to change the compressor with all labor? I live in Arizona.
Props on running nitro through the lines while you braze
Where do yall buy yalls bristol compressors
Can you use a compressor from a 5 ton unit in a 4 ton unit ?
Question: if your compressor contaminated your system should you purge it with nitrogen or does the filter take care of it all?
Wish u were my teacher. I’m a certified type universal tech at entry level but where I live no one will give me a chance.
Dont give up. The suggestion that I offer is find any job that will allow you entry level. Before I started doing the work I do now worked construction and the main job I had was bringing in material... sheetrock lumber doing punch lists... moved on to maintenace as an entry level... cleaning dumpsters, painting curbs... got into sheetmetal... my job was to hold heavy duct work on a 20 ft ladder... the point is at each job I started from the bottom and worked my way. I am a Christian so I did pray alot! 😅 I asked the Lord to open up opportunities for me... who you see now on this channel it took years of diligent hard labor... waiting patiently until opportunities opened up. The point is start somewhere even if its somewhere lower. I hope this is life advice that you take in your mind and allow it to penetrate your heart. I will never forget 2 statements from different people that years later I still remember and apply...
One boss in construction told me... if you learn to find the job that nobody wants to do... and do it with all your strength... you will always have a job.
Another boss in maintenance told me... your a good at what you do... you will get to the top position one day... dont get big headed.
I apologize for the long response but I honestly feel like you could use it 🙂👍
Keep me posted on how things go for you.
Sam very good advice, I need it to
@@MoreThanMaintenance that is how I started. I was a cook at KFC and watched Maintenance repairing the cookers. I then became a janitor while helping do some mechanics, Maintenance tech in a factory. I went to school for electromechanics while doing this. Now I am learning Hvac at 52 years old!
Can I replace my R22 compressor at this time?
