You need a tone generator/linemans set for tracking down those rogue thermostat wires. Takes the guesswork out! monoprice has a pretty cost effective tone generator and probe set but you can find them all over.
Thanks for all of your great videos. I don't know why I found your channel, and I am actually an electrical engineer, so I don't know why I have watched it for so long.

Thanks for your hard work.
@@matthiasplus6691 He probably went downstairs only to find out that the thermostat does not work properly this time either. I guess. Provided he did not want to check our attention.
hey chris bro , the evaporator is upside down , i think the evaporator must turn the other side , because now the olie never kan turn back 2 the compressor , all the oil stand in the evaporated , am i wrong ?
Wonderful example of your can-do attitude. I hope the customer understood all that you did and you didn't (in the end) suffer from the discovery that after all your initial work there was still a problem.
"can't believe they had me fix this unit" well frankly.. this is gonna be more and more common as we try and reduce the waste and turnover of equipment. doesn't this make more sense for the enviroment?
That's fine until you get a unit with metal fatigue cracks, those have been shown on this channel too. It's also wasteful to rebuild the unit like this, only to have the sheet metal supporting the blower motor crack, and then the new compressor and condenser will go in the trash* because they don't sell a new sheet metal assembly. You can't just do parts replacement forever, everything has a lifetime, and some parts just aren't replaceable. * I say trash because there are too many places where if you don't leave the old parts outside for the tweakers to steal and sell, they will break in and steal the new good stuff.

Not an hvac guy. But for some reason these videos are interesting. I . Drive a truck and the truck stop I was at had hvac company replace a compressor and the next day the bathrooms were like a walk in... burrr.. lol
One thing to always remember is that if you are planning to work with any sort a flame like this Wear 100% cotton clothing as other materials can melt to your skin as where cotton just burns giving time to get the clothing off
I always forget you're measuring in Fahrenheit. When you say it's like 100° out there, I'm like "how the hell can you still be alive in such temperatures?". Then I remember you don't measure in Celsius, so it's not literally boiling hot out there.
I think your using about 5x more temperature then your really need, And i'm not sure what to believe about that weld. Need to go and do some reasearch about it.
20:40 are they with any "power company gets to turn on your AC for you" program? Lol. Also, are the remote sensors wireless? Could be someone unmaliciously measuring their fridge temp, or maybe a competitor maliciously sending bad wireless signals, lol...
I know this is ages ago and not much can be done now, but I was rewatching and at the 34:00 mark you can start to hear a compressor having fun with its low pressure switch. Fun to come back and listen for that stuff, pick out things that were not heard the first time.
Man that's something to basically rebuild the whole entire unit. It sucks that you couldn't get one but at the same time it's gotta feel good to take something old and worn out and dang near make it new again
we sometimes did that, back in the old days, at 7-11 stores in San Diego County. The key was that you had to eliminate the controls xformer in one of the two units. Otherwise, the two transformers would drive each other crazy. So, you ran both units on one xfrmr. you needed a stat with 2 stages of cooling, obviously.
Good ol so cal weather, never know what’s going to happen, hot one day, thunderstorms the next, gonna be a weird summer I’m sure, the brazing montage music is definitely a good choice! You were literally two blocks away from my house in this video lol!
Had some rain while on a roof at a store last week here in AZ and I stopped what I was doing, took my hat off and just enjoyed it haha This heat makes you desperate for shade and rain
Equipment leadtimes are absolutely insane now. I've got a project where a client has a single large custom air handler which had an 80-ton split condensing unit for cooling, and at some point somebody replaced it with a 60-ton and they can't operate the building in the peak summer because it's undersized, and probably was undersized in the first place. We're going in with a new 90-ton unit (and replacing the evap coils and lines since we are switching R-22 to R-410A). Trying to get another condensing unit that large is anywhere from 30 to 50 weeks. It's crazy.
All I can say is WOW!!!, that's a job there. I have plugged fixed orifice evaporator to replace coming up. Watching this , I will be taking the condenser out to get better access. Thanks man.
Some people have had luck pushing nitrogen backwards thru the coil while gently heating all the fixed orifices. But Tempstar/ICP units getting access to that part of the evap is challenging to say the least. I think it's waxes and sludge from dirty condenser coils that plugs up those short orifice tubes. Trane units can do the same thing, just not as often
You know, I love these videos, but mostly because I can identify exactly what building you're working on... It takes some references and Crossings to figure out, but I love the hunt. :)
The tool that is supposed to straighten the fins are too big for modern ac. In my ac I had to painstakingly use tweezers to reliably staighten some fins. it's not perfect but compared to the one HVACR does in this video, it's day vs night.
Hey hey as a fellow HVAC / R installer repair I do have a question. I know obviously doing a full rebuild is better than just patching it. Now my question is... Wouldn't it be cheaper on the client ( but then again it might just be me ) , isolate both compressors and just recover r22 , flush r11, and replace dryers and use rs44 - it's direct drop in and I find it better cooling / heating transfer ratio... Thoughts?
R22 in USA is banned for use, fill up of already R22 systems and manufacturing so refilling it is not in par with that? And it will just be destroyed so any air in it wouldn't matter? And any release at all to the atmosphere would be a very, very good thing.
R22 is not banned for use in the US we are allowed to use it they just can no longer produce and or import new R-22 into the US. But the suppliers have stock piled it so we are just using up their stockpile
@@HVACRVIDEOS Wow, that is just completely insane. Its totally banned for all type of use or refill in EU since 2014, why that is not also the case in USA is just beyond me.
I work in an auto a/c shop, I see a lot of shade tree mechanic victims where the compressor is replaced but the orifice tube is left alone. Burns the new compressor up and the customer is left wondering why 😁 Then when you pull the orifice it's plugged with shrapnel
Holy crap.....there's NO WAY you really installed a defective "ON DELIVERY" BRAND NEW coils and you say "I didn't see that" as your installing it AND IT'S YOUR COMPANY. DUDE! YOU THEN POST IT ON THE INTERNET. This is bad. Asking for trouble. Installing parts already defective sounds like a sketchy way of doing business.
This is crazy. I retired last year after 31 years and I worked for JCI/York doing factory start up on most York product. I also worked for Therma in the Bay Area that had about 160 Technicians in about 2000 employee’s. I remember going to Slacky Brothers or other vendors and park between pallets of package units. For my side job Willy Saturday project. We all did them. When you see a HVAC teck driving a Harley you know exactly how he got it !! Lol. Things have sure changed in the industry. As far me I’m to old to be “Sidejob Willy but not too old to ride my Harley “. Be safe out there
I retired from Stationary Engineers local 39, in 2008. I still work as a relief engineer 400-500 hours per year. I'm 73 yrs old now, and I'm not looking to bust my butt all day long anymore. But, I get called from 3 different facilities to sit in when the chief goes on vacation, and there is an understanding that I'm there to keep an eye on the place and pick up the phone if something goes radically wrong. Life isn't too bad in these golden years. I worked at the 1111 Broadway high rise, in downtown Oakland. York did our chiller annuals. We had a 900 ton and a 450 ton. John and Darrel from York/JCI did our annuals. Best rgds.
@@izzydayid7989 . Yes those are my guys. I also worked with Randy and David. We all retired within 5 years of each other. The Pre JCI day’s was the best. We had the best crew. Because we were all the same age and went through the apprenticeship program together. I didn’t do tear downs. I did start up on the large vav boxes and drives, air handler system with JCI controllers. I was familiar with both products. I end up going all over the country doing start up and system commissioning specially with a lot of the hospitals. It was-a fun ride just my wife got tired of me not home. Then I had twin son’s and I needed a change. Working for JCI was awesome just a little to demanding. I finished up at Therma. I met a lot of retired local 39 working at UC Berkeley and Livermore National lab. I guess you can double up there and still get your pension. That’s a good gig.
@@samuelaranda4597 I am pretty sure that after age 71, a local 39 retiree can work as many hours as he pleases, in covered local 39 work, and still collect a full pension. I can get a local 39 full time job any time I would want, I believe. at this point, I prefer to take the opportunity to have an afternoon nap on the living room couch as often as possible. But, having said that, I like to work a week or two, here and there, which is what I'm able to do. There are two sites in SF, one man chief jobs, where they use me, when the chief goes on vacation and another pretty nice building in walnut creek. they all have underground parking for me. as long as the pension plan and social security hold up, I won't go back to work fulltime.....unless something too tempting to resist appears. Best regards.
Ah that feeling of what did I fuck up now , when you get a call back is crazy, especially when you know you did everything right, but it's the amount of moving parts in HVACR...i love it though.. Great job as usual man, thorough as always. I know Brazing to some people might be mundane but I still love watching y'all do it, you did that with music too btw and you seem a master with the oxy/acet torch, I am partial to my Turbotorch and I use my oxy/acet set up for brazing inside cabinets or tight spots but I'm starting to like it a little bit more for other stuff...the soot tho, it's ridiculous, still trying to find that oxy balance on first lit, but hey. Keep up the thorough work ethic man
I use a turbotorch with an adapter to use a small 10 cu ft MC tank. Much easier to get up a ladder on the roof. There's no need for oxy/acetylene unless trying to silver solder a big brass distributor onto like a 12.5 ton TXV. That does get challenging to get enough heat in it quick enough even with a big tip that drains that small tank in under an hour. But for just copper to copper normal joints, a good turbotorch is more than enough heat to get the job done.
@@brnmcc01 If you do only HVAC then maybe not, but for Refrigerators and small reach-ins, the oxy/acetylene torch is perfect. The turbo torch starves for oxygen in tight quarters and they spread the heat everywhere which can ruin the whole interior.
@@marjones69 That's a good point, I've run into that problem of starving for oxygen, but on a lot of reach ins, the condensing unit can be slid out a bit. When replacing the TXV on a 3 door Randell prep table recently, was very cramped space, but with all three doors propped open, and removing the fan wiring harness so it wouldn't get melted, it wasn't too bad. Hate those mullion evaps, hard to work on, and they always cram food and stuff up against it, blocking the airflow etc...
@@marjones69 Biggest thing that sucks with the turbotorch is like when you have to attach a TXV to a big heavy brass distributor or something like that. The turbotorch can't get enough heat into something heavy fast enough to reach brazing temp before the heat transfers away. But staybrite #8 silver bearing solder works good in a case like that.
peeling a onion will always make you cry.. all the layers of a old previously neglected project thats new to you.. is frustrating.. all you can do is be honest and bite your tongue when talking to customers... You did it right, when those that came b4 you did it half assed or wrong is a slow proof ... proving your integrity can be a slow and ongoing battle in this situation. All I can say is...eventually it will be recognized... If not then you can walk away knowing you did the best you could with what was handed to you...nothing good comes easy.. specially when it comes to HVAC
Hmm I wonder if the 24v color code is a regional thing. it seems like since 2 stage has been popular most people use blue for common and brown for y2. And orange for reversing valve. Lol that’d be a pain In The butt if we all did it different
I hate a hack job as much as the next guy however, in reference to the zone sensors; There are times you do a temporary fix and as far as the customer is concerned it's working. You can explain it's temporary But it's not a long term solution. Sometimes they listen, sometimes they don't. Just another challenge in this industry With rising material and labor costs, Just something to consider in fairness to the techs you follow.
I use the same method where I purge my hose up to the inlet port on the recovery tank. The only thing I do different is I never use my digital gauges for recovery. I have an old pair of analogs that have been relegated to being on s%#t detail as we’d say in the military 😂. Maybe I’m just a little too ocd but I reserve my digital gauges for new installs or parts changeouts.
Love the montage music you use which song is this one if you don't mind . Love how you can't find parts last summer had a hvac look at my mom's unit I'm a welder by trade but many other trades also intrest me but couldn't find the start caps for the compressor or the condenser fan at all his suppliers in the end found it myself lol he literally asked my mom why she didn't let me do it thank God I took picture's tho he couldn't figure out the wiring cause I had to take the caps to get the new ones so thankfully he figured it out by talking to me and by the pics but said looked like it was leaking thankfully it isn't
i just caught the space balls reference for the chapter in the vid where you were realigning/combing the fins on the evap coil and that made my day haha
Do you have a way to leak test the evap coil (or any coil you put in) before you fully put it into the unit? Considering the damage you saw from shipping, I'd be super worried that something was messed up once you got it all back together. Love your vids, Thanks!
We avoided traffic damage by picking up parts/equipment at the wholesaler's warehouse. They also kept a few discounted units with cabinet damage for sale.
I like to use those Honeywell redlink zone sensors and the honeywell vision pro thermostats in a lot of restaurants I have. Easy to mount the sensor where you want it, and no have to try and figure out how to run wires thru a complex building. One restaurant/night club I have has literally 5 package units, 2 split system heat pumps, and a mini-split in the kitchen... And they wanted all 7 thermostats in the office...
everything digital, but still using r22... you're doing a great job, but better get away ozonedepleting coolants please... In europe it's even illegal to use recovered r22 (except for historic reasons)
Show me the definitive proof where the hole in the ozone layer was caused by these products? I can't find it. It appears to be the usual junk science they push to create these money grabs. Its funny that the newer freons were invented to be eco friendly,but yet another new standard is now coming around,more money.
We're seeing it more especially quick repairs of our product for the oilfield and others critical infrastructure. They'll pay to fix our 20 year old obsolete product if we can and I suspect pray they can get the replacement system up and running before that fails (It shall not). They're working with us and other vendors to manufacture new generation parts, deliver them, debug programs, test them, test the machine and then get their machine re-certified. I'll turn the fixed units in under 4 weeks, new is 12 weeks out, recertification is a several months out if all the bits of paper flow as well as the oil should. Government paper flows about as well as flushable wipes. Oh, I don't make as much as an HVAC tech but my back is good and I work in AC. ;)
well, I can see that you walked into a mess created by someone else. you did a heckuva job. the second segment, when you got called back the next day was the trigger for so many "bitter memories" of my days as a field service technician. I worked as a field service tech from '75-85, and then transitioned to becoming a building (stationary) engineer., in the SF Bay area that worked out pretty well for me. I'll finish watching the video, to find out if it was another tech, or the owner himself, who fouled up the controls. That's tough, when you go into a place for the first time, and you get caught up in the bad practices of some other individual. Enjoyed the video a lot. ZSt first, I missed being a field tech, calling my own shots. But, then seeing the can of worms that you walked into, beng a stationary engineer, does have it's advantages, despite the fact that you may not always have the same level of self-authority. $0 hours per week, every week. you get to know your site intimately, less likelihood of unforeseen surprises, whatever! Thanks for sharing your system overhaul. Good job.
Depending on the unit, breaking the blower contactor MAY be the only way to immediately shut the blower down. There are units that have a delay when you drop power from the R. R=R W=W W2=Brown Y=Y Y2=Orange G=G C=Blue(because it is AC power) But like you said, no real standard. If it is DC power, then "C"=Black
I in my second year of my own Restaurant service and repair. I have been in the restaurant service for 25 years. I’m a full restaurant repair service company. I have enjoyed watching your videos and came across your videos when I was researching r490 videos. Thank you for the videos they have been fun to watch. Jason from Birmingham.
So , in that particular setup the thermostat controls settings and the zone sensor bypasses the sensor in the thermostat and gathers its readings from the sensor only? I gather it’s to prevent employees and guest from adjusting temp settings? I’ve seen that type thermostat on a marvair unit. What terminal is used for zone sensor? A1, A2?
Nm. I see a1, a2, and a3 control dampers and other equipment. The one I just read up on had a dedicated spot for remote supply temp and humidity sensors.

Wouldn't it be cheaper on the client ( but then again it might just be me ) , isolate both compressors and just recover r22 , flush r11, and replace dryers and use rs44 - it's direct drop in and I find it better cooling / heating transfer ratio... Thoughts?
But is it profitable for the tech? 🤔
R22 in USA is banned for use, fill up of already R22 systems and manufacturing so refilling it is not in par with that? And it will just be destroyed so any air in it wouldn't matter? And any release at all to the atmosphere would be a very, very good thing.
R22 is not banned for use in the US we are allowed to use it they just can no longer produce and or import new R-22 into the US. But the suppliers have stock piled it so we are just using up their stockpile
@@HVACRVIDEOS Wow, that is just completely insane. Its totally banned for all type of use or refill in EU since 2014, why that is not also the case in USA is just beyond me.
Never daisy-chain your zone grounds....
so interesting that the thermo wiring's not in conduit, would make replacement so much easier
Great video. I have learned alot from your videos. You do good work and despite the obstacles you face, you push through and get the job done.
0:59 that sound of your voice Chris I get those days hahaha THAT INVOICE though ;)
We got our “brazing music” fix! LOL! Keep up the great work and thanks for the videos! Be safe and stay kind.
Looks like legionaires disease in that drain
I wonder if this is the new paradigm for the next few years. Make what ya got work.
I love this videos, they are 👁 opening when I have to troubleshoot my units at work, thanks Chris you are tech and teacher, God bless you.
Red link for the win boss lol
You certainly did it the right way but man redlink would have saved you allot of work on that one.
I work in an auto a/c shop, I see a lot of shade tree mechanic victims where the compressor is replaced but the orifice tube is left alone. Burns the new compressor up and the customer is left wondering why 😁 Then when you pull the orifice it's plugged with shrapnel
Holy crap.....there's NO WAY you really installed a defective "ON DELIVERY" BRAND NEW coils and you say "I didn't see that" as your installing it AND IT'S YOUR COMPANY. DUDE! YOU THEN POST IT ON THE INTERNET. This is bad. Asking for trouble. Installing parts already defective sounds like a sketchy way of doing business.
This is crazy. I retired last year after 31 years and I worked for JCI/York doing factory start up on most York product. I also worked for Therma in the Bay Area that had about 160 Technicians in about 2000 employee’s. I remember going to Slacky Brothers or other vendors and park between pallets of package units. For my side job Willy Saturday project. We all did them. When you see a HVAC teck driving a Harley you know exactly how he got it !! Lol. Things have sure changed in the industry. As far me I’m to old to be “Sidejob Willy but not too old to ride my Harley “. Be safe out there
I retired from Stationary Engineers local 39, in 2008. I still work as a relief engineer 400-500 hours per year. I'm 73 yrs old now, and I'm not looking to bust my butt all day long anymore. But, I get called from 3 different facilities to sit in when the chief goes on vacation, and there is an understanding that I'm there to keep an eye on the place and pick up the phone if something goes radically wrong. Life isn't too bad in these golden years. I worked at the 1111 Broadway high rise, in downtown Oakland. York did our chiller annuals. We had a 900 ton and a 450 ton. John and Darrel from York/JCI did our annuals. Best rgds.
@@izzydayid7989 . Yes those are my guys. I also worked with Randy and David. We all retired within 5 years of each other. The Pre JCI day’s was the best. We had the best crew. Because we were all the same age and went through the apprenticeship program together. I didn’t do tear downs. I did start up on the large vav boxes and drives, air handler system with JCI controllers. I was familiar with both products. I end up going all over the country doing start up and system commissioning specially with a lot of the hospitals. It was-a fun ride just my wife got tired of me not home. Then I had twin son’s and I needed a change. Working for JCI was awesome just a little to demanding. I finished up at Therma. I met a lot of retired local 39 working at UC Berkeley and Livermore National lab. I guess you can double up there and still get your pension. That’s a good gig.
@@samuelaranda4597 I am pretty sure that after age 71, a local 39 retiree can work as many hours as he pleases, in covered local 39 work, and still collect a full pension. I can get a local 39 full time job any time I would want, I believe. at this point, I prefer to take the opportunity to have an afternoon nap on the living room couch as often as possible. But, having said that, I like to work a week or two, here and there, which is what I'm able to do. There are two sites in SF, one man chief jobs, where they use me, when the chief goes on vacation and another pretty nice building in walnut creek. they all have underground parking for me. as long as the pension plan and social security hold up, I won't go back to work fulltime.....unless something too tempting to resist appears.
Best regards.
@@izzydayid7989 yes a afternoon nap is highly underrated.
Ah that feeling of what did I fuck up now , when you get a call back is crazy, especially when you know you did everything right, but it's the amount of moving parts in HVACR...i love it though.. Great job as usual man, thorough as always.
I know Brazing to some people might be mundane but I still love watching y'all do it, you did that with music too btw and you seem a master with the oxy/acet torch, I am partial to my Turbotorch and I use my oxy/acet set up for brazing inside cabinets or tight spots but I'm starting to like it a little bit more for other stuff...the soot tho, it's ridiculous, still trying to find that oxy balance on first lit, but hey.
Keep up the thorough work ethic man
I use a turbotorch with an adapter to use a small 10 cu ft MC tank. Much easier to get up a ladder on the roof. There's no need for oxy/acetylene unless trying to silver solder a big brass distributor onto like a 12.5 ton TXV. That does get challenging to get enough heat in it quick enough even with a big tip that drains that small tank in under an hour. But for just copper to copper normal joints, a good turbotorch is more than enough heat to get the job done.
@@brnmcc01 If you do only HVAC then maybe not, but for Refrigerators and small reach-ins, the oxy/acetylene torch is perfect. The turbo torch starves for oxygen in tight quarters and they spread the heat everywhere which can ruin the whole interior.
@@marjones69 That's a good point, I've run into that problem of starving for oxygen, but on a lot of reach ins, the condensing unit can be slid out a bit. When replacing the TXV on a 3 door Randell prep table recently, was very cramped space, but with all three doors propped open, and removing the fan wiring harness so it wouldn't get melted, it wasn't too bad. Hate those mullion evaps, hard to work on, and they always cram food and stuff up against it, blocking the airflow etc...
@@brnmcc01 True, I suppose once you get good with a tool you tend to stick with it...the worse thing is to mess with something new and have to redo
@@marjones69 Biggest thing that sucks with the turbotorch is like when you have to attach a TXV to a big heavy brass distributor or something like that. The turbotorch can't get enough heat into something heavy fast enough to reach brazing temp before the heat transfers away. But staybrite #8 silver bearing solder works good in a case like that.
We have been doing a bunch of commerical installs lately Carrier 5-10 ton RTUs.
Rebuilding an entire old package unit is par for the course for a hospital that falls under OSHPD regs.
peeling a onion will always make you cry.. all the layers of a old previously neglected project thats new to you.. is frustrating.. all you can do is be honest and bite your tongue when talking to customers... You did it right, when those that came b4 you did it half assed or wrong is a slow proof ... proving your integrity can be a slow and ongoing battle in this situation. All I can say is...eventually it will be recognized... If not then you can walk away knowing you did the best you could with what was handed to you...nothing good comes easy.. specially when it comes to HVAC
Are the easy-up canopies your main weapon on the hottest days, or are there other tactics you employ? 120 degrees is no joke!
Hmm I wonder if the 24v color code is a regional thing. it seems like since 2 stage has been popular most people use blue for common and brown for y2. And orange for reversing valve. Lol that’d be a pain In The butt if we all did it different
I hate a hack job as much as the next guy however, in reference to the zone sensors; There are times you do a temporary fix and as far as the customer is concerned it's working. You can explain it's temporary But it's not a long term solution. Sometimes they listen, sometimes they don't. Just another challenge in this industry With rising material and labor costs, Just something to consider in fairness to the techs you follow.
I use the same method where I purge my hose up to the inlet port on the recovery tank. The only thing I do different is I never use my digital gauges for recovery. I have an old pair of analogs that have been relegated to being on s%#t detail as we’d say in the military 😂. Maybe I’m just a little too ocd but I reserve my digital gauges for new installs or parts changeouts.
Love the montage music you use which song is this one if you don't mind . Love how you can't find parts last summer had a hvac look at my mom's unit I'm a welder by trade but many other trades also intrest me but couldn't find the start caps for the compressor or the condenser fan at all his suppliers in the end found it myself lol he literally asked my mom why she didn't let me do it thank God I took picture's tho he couldn't figure out the wiring cause I had to take the caps to get the new ones so thankfully he figured it out by talking to me and by the pics but said looked like it was leaking thankfully it isn't
Why do the drain pan threads crack, like you said?
Unless you are continually removing the fitting, what is the cause?
Nice
you got best videos I am so glade your makeing videos. I am makeing new watter park and indoors with hotels n exta your videos are so inforitive.
24:55 little different from how we do it in FL, Blue is preferred for C and Brown is preferred for Y2, funny enough its the exact opposite.
Get a Greenlee tone and probe kit, it'll make your life so much easier.
It's what I use every day in the telecomm industry.
big shout out from Arizona . . lake havasu city #respect Chris , a full "restoration" on that Bitch . . #keep #em #going
I require source! It'd be lovely if you'd list the titles of the tracks you use for your brazing montages.
Jesus, Chris. Are you in palm desert that it is so hot?! 125 deg?!
33:03 - You sold me right here when you said your hats are flex fit! Those are rare next to the more common "ponytail" hole in the back.
i just caught the space balls reference for the chapter in the vid where you were realigning/combing the fins on the evap coil and that made my day haha
24:39 that's not how you use WAGO connectors dude
Yeah good catch, I realized the problem really quick.... brain farts happen to the best of us
(19:46) are those two stat's in Celcius? 35 degrees cel, sounds about right...
How on earth is packing the evaporator so it can be so badly damaged like that even remotely acceptable?!
That's why you go by letter and not color. But common should be blue not brown just saying 😂
its funny, I like using blue as common. its a Trane thing vs Carrier thing ;)
Did I just hear "Viper Big Boob" 🤣🤣🤣🤣🤣🤣
Monsoon season is a godsend for us here in Southern AZ...
...let it RAIN!
Welcome to the shit show per Steve Lav of You Tube. Good work.
Do you have a way to leak test the evap coil (or any coil you put in) before you fully put it into the unit? Considering the damage you saw from shipping, I'd be super worried that something was messed up once you got it all back together.
Love your vids,
Thanks!
You could probably braze in some pinched copper with a service port and try that out. Sweat back out once you are satisfied with the results
We avoided traffic damage by picking up parts/equipment at the wholesaler's warehouse. They also kept a few discounted units with cabinet damage for sale.
DID YOU USE POE OIL on the 407c compressor?
I like to use those Honeywell redlink zone sensors and the honeywell vision pro thermostats in a lot of restaurants I have. Easy to mount the sensor where you want it, and no have to try and figure out how to run wires thru a complex building. One restaurant/night club I have has literally 5 package units, 2 split system heat pumps, and a mini-split in the kitchen... And they wanted all 7 thermostats in the office...
My god that music during the brazing is down right hypnotizing
Why the copper drain lines? Here in TN we just use pvc
everything digital, but still using r22... you're doing a great job, but better get away ozonedepleting coolants please... In europe it's even illegal to use recovered r22 (except for historic reasons)
Show me the definitive proof where the hole in the ozone layer was caused by these products? I can't find it. It appears to be the usual junk science they push to create these money grabs. Its funny that the newer freons were invented to be eco friendly,but yet another new standard is now coming around,more money.
Where are the expansionValves/cappilary tube?
Geebus, is this place called Murphy's Law?
We're seeing it more especially quick repairs of our product for the oilfield and others critical infrastructure. They'll pay to fix our 20 year old obsolete product if we can and I suspect pray they can get the replacement system up and running before that fails (It shall not). They're working with us and other vendors to manufacture new generation parts, deliver them, debug programs, test them, test the machine and then get their machine re-certified. I'll turn the fixed units in under 4 weeks, new is 12 weeks out, recertification is a several months out if all the bits of paper flow as well as the oil should. Government paper flows about as well as flushable wipes. Oh, I don't make as much as an HVAC tech but my back is good and I work in AC. ;)
I prefer blue for common, I am curious what other people prefer.
I know you just do commercial work, but if you had to replace your ac condensing unit at your house. What brand would you choose?
Which one is better R22 or 407c.
R-22
I love that torch tip Chris, what number or kind is it?
well, I can see that you walked into a mess created by someone else. you did a heckuva job. the second segment, when you got called back the next day was the trigger for so many "bitter memories" of my days as a field service technician. I worked as a field service tech from '75-85, and then transitioned to becoming a building (stationary) engineer., in the SF Bay area that worked out pretty well for me.
I'll finish watching the video, to find out if it was another tech, or the owner himself, who fouled up the controls. That's tough, when you go into a place for the first time, and you get caught up in the bad practices of some other individual. Enjoyed the video a lot. ZSt first, I missed being a field tech, calling my own shots. But, then seeing the can of worms that you walked into, beng a stationary engineer, does have it's advantages, despite the fact that you may not always have the same level of self-authority. $0 hours per week, every week. you get to know your site intimately, less likelihood of unforeseen surprises, whatever!
Thanks for sharing your system overhaul. Good job.
Depending on the unit, breaking the blower contactor MAY be the only way to immediately shut the blower down.
There are units that have a delay when you drop power from the R.
R=R
W=W
W2=Brown
Y=Y
Y2=Orange
G=G
C=Blue(because it is AC power)
But like you said, no real standard.
If it is DC power, then "C"=Black
Ok, the music selection during the Brazing Montage gave me the biggest SynthWave 80's vibe...more of it! Keep the great content coming!
I in my second year of my own Restaurant service and repair. I have been in the restaurant service for 25 years. I’m a full restaurant repair service company. I have enjoyed watching your videos and came across your videos when I was researching r490 videos. Thank you for the videos they have been fun to watch. Jason from Birmingham.
So , in that particular setup the thermostat controls settings and the zone sensor bypasses the sensor in the thermostat and gathers its readings from the sensor only? I gather it’s to prevent employees and guest from adjusting temp settings? I’ve seen that type thermostat on a marvair unit. What terminal is used for zone sensor? A1, A2?
Nm. I see a1, a2, and a3 control dampers and other equipment. The one I just read up on had a dedicated spot for remote supply temp and humidity sensors.
