Great video. I wonder if your customers watch these videos. They are literally getting quality work. You went above and beyond on a unit that is ready to die.
This was a very informative video. It really helped me a lot because I was experiencing these same symptoms with a 4,5ton AC. Had restriction in the metering device
Once again another detailed diagnoses. I do a lot of grocery store refrigeration and hvac. I find myself doing more refrigeration so my hvac game has gone down. But watching your videos has been improving my game. Keep up the good work bud.
As someone who isn't an HVAC tech, really appreciate your simple yet effective explanations of what the various bits of these units do and how they fit together. Unfortunately everyone skimps on PM in every industry... and the results are always bad.

I would talk to the owner for permission to acid test the oil and at the same time just replace both liquid and suction filters (in a month or two). Good choice on the filters!!! Sporlan was the only kind I ever used --- they never let me down!!! Overall, you've done a great job from what I can tell!!!!
Damn, now that looks like a unit that should be completely replaced hands down. But as the customer wishes right? At least it provided an opportunity to further practice your skills and prove to us and yourself once again that you can basically build a package unit from scratch! 👍 on the music
All that work in labor probably cost half or more of the cost of a new unit without even the benefit of a warranty. Miracles aren’t cheap and get charged accordingly, and if the customer is willing to pay them and sign off that the contractor is not liable or responsible for the unit’s performance or quality control more power to them. That thing may last less than a year and the customer may have to pull the trigger on the replacement anyway. The customer is throwing money away there for sure but hey, they are always right. 🤷♂️
Love to watch you busy as a service tech. Brings me back to my biggest love what i miss daily. You bring me back in memory lane, keep up the awesome work :)
Chris. I love your proffesioalism/ work. I've been doing this trade probably 2x long as you have and once in a while I learn something else from you.. That's a compliment to you.. I'm sure your like me also with learning something new everyday. A bad day it is for me if I can't think of something new learned I don't understand CA though. Here in stupid IL no one would do or anyone pay what you do there vs. replacing. No offense in any of my comments. Hopefully you have not blocked me!?
Changing the orifices has about a 45% success rate. Too many times the evap itself has an issue internally. I did not think it was possible until I had done three units over five years and had a metering/suction pressure issue when the job was done. A new evap and header works 100% of the time, so they are all quoted that way. No muss, no fuss.
I love seeing timelapse/fast forward done to see all the work that goes into these units. Gives somewhat more understanding to what it takes to do the job right :) Love seeing your work and how you go about with diagnostic and repairs!! Thumbs up 👍
Just had this same exact problem today and heating up the metering devices didn't work, this video clears up why and answered all my questions. Whenever I come across a similar problem I remember watching one of your video from the past on it and gets me through those frustrating calls. -My boss always told me when I was an apprentice. "You should be paying me for me teaching you like the university does!" Haha thank you for your helpful content.
I will discuss this on my Livestream this evening 8/9/21 @ 5:PM (pacific) on TH-cam come over and check it out th-cam.com/video/exNsJRteDOU/w-d-xo.html
I've been watching you the last couple weeks and I'm in awe of you skills and dedication to the craft. Looking forward to learning more from the master.😊
I appreciated the followup, clarification on the drain trap and cleanout setup. On previous vids, I have been concerned on how you prevented air backflow into the unit. The cap on the unit side is a perfect solution. Love the elevation steps for extra protection.
All the customer looks at are the costs not realizing that proper PM will drastically save money and cost less in the long run with fewer breakdowns as well! Great job Chris!
dude your videos are the best video's to teach apprentices anything HVAC servicing related I'm currently in my last year of study in Australia, and I've been in install work most of my years. these videos are the best! big ups !!!! keep posting
the old saying is "those who can, do; those who cannot, teach". I am not certain that it's true but often sure seems to be. I love these videos and I have literally no interest personally in commercial HVAC. I enjoy the diagnostic process. The same sort of logic, I have used initially in automotive with vehicles, then as a career paramedic with humans, and with a computer networking business. The media are different but the logical process is spot on the same. Big picture, think about what is happening and what could fail. Rule out potential causes. Identify the problem and remediate.
Love your content, keep it up. Little tip, for anyone interested, on the first Tee for the condensate trap one can solder a female adapter and put a brass plug with some PTFE tape on it to produce a better seal on the suction side of your wet seal in your trap. Thank you again for sharing your knowledge with us.
cost is far higher, at least here in USA. he could smear it with a blue "locking" pipe thread compound and it would seal nearly perfect air tight ( at very low pressures)
my colleagues also were amazed to what degree i disassembled beamer when i repaired them, without manuals or education into it "its´not rocket science"
What I’ve found that most often clogs the piston is high head pressure. When the condenser motor quits. This causes the compressor to run hot,breaking down the insulation of the windings. In the video I could see an after market motor. This is really bad with the larger Carriers with 2 motors. One quits and starts spinning backwards. 410 units are the worst. Always check the bearings on inspections. Replace them before they fail. Stay safe.
I learned many hard lessons over the years ; If it makes better sense to replace the RTU ,price the repairs higher than the cost of a new RTU and the RTU get's replaced . It's always about money !
what I have found in Alaska roof top units, is they are clogged with cottonwood fuzz in the summer and snow drifts that cover the Entire unit and freeze the condenser coil and fans. because the units placed directly on the floor of the roof and the fans pull everything into the coils.
That oil is going to eat the roof. I would have advised replacing the whole unit. Did you say it was a 2004?? Let’s hope the compressor doesn’t fail. Seems like so much work for this old dog. I retired 16 years ago, and those units were old then. I think the cause of the restriction is the oil breaking down and forming wax in those offices. I’ve heard of that fix with the torch. Trane had the same setup. Oh, that insulation on the windings is not a wax. It’s like a baked on varnish. I’ve seem motor re winders apply it, and then bake the windings in an oven. The wire is insulated before it is wound into windings, and placed on the stator core, then they spray another layer, and put the whole thing in the oven. You’re right about acidic oil eating thru it. It can also fail with excessive starts and stops. Every time the motor starts the windings flex, and eventually wear off the insulation, and you get a turn to turn short. The insulation condition can be checked with a megger. I probably would have megged out that compressor, before I started with the repair, especially being that it’s had a rough life.
I have two carriers like that right now and have fixed multiple with cap tube and a piston flange. I talked to carrier tech support when a compressor went and told him I was going to instal those cap tubes also. He was like “why just blow it out with nitrogen” lol sure guy.
Do you ever send oils out to a lab for analysis? Wear metals, acidity, etc.,? You could probably send a sample of clean oil and dirty oil to Finning SOS Labs. Their tests are pretty cheap and it could give you an early warning in the case of the compressor you showed in this video.
I used to use all copper RTU drains because the plumber's plastic pipe gets all brittle & cracks. I started using plastic electrical conduits for RTU drains. 10x better resistance to UV and cheaper than copper.
I used to live in a more urban area and one time I was working and this HVAC repair guy came in and was up on the fixing one of the things and he did it a few times but I was there this time. He found our porter gave him like 10 bucks and had him help pull the top.
I'm no HVAC expert, but an iced coil usually means something's gone wrong. I like that you took the entire unit apart and looked at everything. I like the music you used. Sounds like a MIDI synthesizer created it. Did you make it yourself, or is it available somewhere that I can find it?
i love the 80's montage music, Just need you and your apprentice doing a jumping high five at the end of the clip lol. Shirts off preferred for bonus points. =D
I’ve had similar results with alternate refrigerants. They can be hard to dial in. I’ve had success with R-422B, but even it can be difficult depending on the system. I think we’d all like to use R-22 in a situation like that, but the cost is just sky high.
@@BullmastiffForce basically yes. We haven’t been able to produce or import any R-22 for about a year and a half. So, supply companies had stocked up, and just selling what they have left. Now the price is so high to buy a jug of R-22 you rarely see anyone using it.
What only the last two years?.... Here in Norway it was iligal to fill an exsisting system with R-22 in 2015. New system got banned in 2004. Now we only are allowed to change oil and filter without relese of the gas according to the F-Gas regulation.
@@einderha well they’ve been slowly cutting back production a little at a time for at least the ten years before production was completely halted 2 years ago. So, price has been going up for years. It’s only now that the price has become too expensive to consider. About 2 months ago I bought a 30 lb. drum and it was $1200. And it’s gone up more since then.
You shouldn't flux your solder joints AFTER you finished soldering. This can cause micro cracks in the solder from rapid cooling. This could cause leaks in the future especially if you were doing a pressurized water line.
I’m waiting on one of those headers to come in from backorder, wish I would’ve thought to just quote the whole evaporator. It might’ve pushed it over the replacement edge.😂
funnily those are my bedtime videos now... but they also teach me about hvacr more than i did know about heat pumps before. otherwise electronics guy / coder / sysadmin here, but i do know fair bit about power too
Damn Chris idk how you work in 121 degree Fahrenheit temperatures I understand is dry where you but man I was in an attic this summer it was over 135 in the attic and I damn near passed out for the heat up there! Nice work man, love what you do and your thought process makes for a damn good video bro! I love the closing words don’t change it for anyone, I love the thought process Chris!
I believe dirty condensors cook the oil in my experience. Never had a problem cleaning condenser like that . Used good coil cleaner on both sides. Then looked though coil light and eyes. Didn't care that much how coil looked . I'd cleaned till looked clear . Just my say. Have a good day.
I noticed your re-plumbing the drain with copper, is that a state requirement/code issue, or due to being on a roof, and uv exposure, is why not being done with PVC pipe?
Its for exactly as you said: UV exposure reasons. PVC will get brittle and crack over time from UV exposure leading to a leaking drain. I was frankly surprised he didn't spray paint that new drain piping black to try and throw off crack heads from stealing it, but he may not have had time and will do that on the follow-up visit.
thanks for another great video, I’ve been learning new stuff from your channel for past 2 years even more than my school man 🙏 also I wonder Changing a burned out compressor requires flushing the condenser And new filter dryer but how about evaporator do you flush them and if you do how can you make sure inside fixed metering device is clear and dry , can nitrogen and deep vacuum get that rx11 out of metering device ?
I have a couple questions for you experts. My AC experience is mostly cars so not completely ignorant but my home heat pump is tempting me greatly to get more training. On to the questions. Why does my heat pump have a small copper line and a large copper line running to the air handler? In a car there is no reversing valve(usually, I guess there are a few new cars, probably electric, that do) because it only runs one direction and thus the small line is the high pressure liquid line. Generally speaking small lines are best for high pressures but if the reversing valve just reverses coolant flow I'd think both lines should be fairly small or slightly bigger than normal. For context this system was originally installed in the early 1980's with a 4ton Lennox. Next question. The copper pipes run underground. Under the sidewalk and under the concrete basement to the middle of the house. What kinds of problems can happen with lines running under ground like that? Will those lines need replaced anytime soon? I'd have given almost anything just to see how they got that line installed.
Great video as always! But i am surprised that with all those repairs you didn't retrofit the refrigerant ? R22 just vanished here and we still have 2000 pounds system running on it. I don't really work on a/c maybe it's different on system under a certain tonnage. Keep it up!
I have a question and maybe I missed it in your video: Why didn't you use a R-22 replacement refrigerant like R-407c? Usually when I am doing any type of work in a rooftop unit like this that I have to change the compressor oil, I would refill with a POE oil and then recharge with R-407c just as a R-22 substitute to keep the refrigerant costs down and for future Refrigerant recharges.

And new filter dryer but how about evaporator do you flush them and if you do how can you make sure inside fixed metering device is clear and dry , can nitrogen and deep vacuum get that rx11 out of metering device ?
The smallest of issues always lead to massive problems, wish some of the kit in the uk was as easy to work on, instead it's cramped in
Ive always read that suction line filter/driers are to be removed and never meant to be permanently installed
I have a couple questions for you experts. My AC experience is mostly cars so not completely ignorant but my home heat pump is tempting me greatly to get more training.
On to the questions.
Why does my heat pump have a small copper line and a large copper line running to the air handler? In a car there is no reversing valve(usually, I guess there are a few new cars, probably electric, that do) because it only runs one direction and thus the small line is the high pressure liquid line. Generally speaking small lines are best for high pressures but if the reversing valve just reverses coolant flow I'd think both lines should be fairly small or slightly bigger than normal. For context this system was originally installed in the early 1980's with a 4ton Lennox.
Next question. The copper pipes run underground. Under the sidewalk and under the concrete basement to the middle of the house. What kinds of problems can happen with lines running under ground like that? Will those lines need replaced anytime soon? I'd have given almost anything just to see how they got that line installed.
Great video as always! But i am surprised that with all those repairs you didn't retrofit the refrigerant ? R22 just vanished here and we still have 2000 pounds system running on it.
I don't really work on a/c maybe it's different on system under a certain tonnage.
Keep it up!
Next time I have to do some hardcore brazing I'm definitely going to play some '80s synth pop music.
I have a question and maybe I missed it in your video: Why didn't you use a R-22 replacement refrigerant like R-407c? Usually when I am doing any type of work in a rooftop unit like this that I have to change the compressor oil, I would refill with a POE oil and then recharge with R-407c just as a R-22 substitute to keep the refrigerant costs down and for future Refrigerant recharges.
I will discuss this on my Livestream this evening 8/9/21 @ 5:PM (pacific) on TH-cam come over and check it out th-cam.com/video/exNsJRteDOU/w-d-xo.html
