You know what you are doing. You are helping others with your knowledge without charge, what the hell do people want? You speak plenty clear, anybody who wants to fuss over slight errors in terminology is just a hater or jealous.

I think a lot of people watch your videos because of your humility, being able to see your "live" troubleshooting and your train of thought. Keep up the great work and stay safe!

Being on top of that roof @ 100 degrees you might slip up on some proper terminology. While working on those units you have a lot going through your mind. I’m sure 99.99% of the people that watch and comment on your channel totally appreciate what you do. I’ve learn more on your channel than anywhere. Thank you Chris!

I almost shit my pants when you grabbed those 200v connectors on the transformer with your bare fingers

A lot of KZfaq channels that started out excellent and then ended up being just good, are the ones which used to show their mistakes and then stopped. Mistakes are where the learning happens, so seeing the mistake helps a lot.

Thats from the show Martin! Made in 1990s! I dont remember much from that show, but he used to say it to his girlfriend/wife i believe!

Manufacturers won‘t tell you how to fully clean their Units. Properly cleaning these condensers means the unit will function much longer than the warranty period lasts. This leads to decreased sales of either replacement parts or whole new units.

It's so cool to me that you encourage your staff to slow down and take their time to do the job thoroughly, not just "right". Too many companies are turn and burn operations running on quantity over quality.

Those who can’t do teach. That teacher couldn’t fix an AC unit if his life depended on it. You keep up the amazing work. You are teaching by example! And it is amazing!

Finally someone has the balls to call out these hidden agendas by deceitful sales talk BY manufacturers!! Great job with the transformer and locating the short and testing the system before part replacement OR unit replacement YOUR Professional and A GEM !!

I have been in this business for 20 years and you a better job than most. I have never seen anyone ever separate condenser coils. Not even the manufacturer. A trainer complaining about your wording... Keep doing what your doing.

Chris. I talk to myself all the time too dude. I find it’s a lot easier to troubleshoot when I talk to myself. It’s healthy

I own a large commercial kitchen. I started watching you videos to help me understand how things brake so i can give better feed back to tech's who fix my equipment. It has even helped me fix a few small things that i would of probably payed 10x as much to get some one to come take a look at.

TBF to you I really wouldn't want my daily jobs video'd and picked apart second by second from YT warriors . Your work is of an extremely high standard and worthy of the best. Of the American techs, I only watch you and HVACTime . What I've seen of the others (I've watched) I wouldn't want them to park on my drive let alone get their tools out. The double row thing caught me out some 20 years ago on a Daikin VRV condenser. looked clean on the outside and in but was tripping on high head.. Pulled them apart and it looked like someone had slipped some carpet tiles in there.. great work keep on keeping on

4:18 One great tool to test transformers is an resistance measurement tool which uses AC instead of DC. If any wires are shorted internally, the AC resistance on any coil drops, while only the shorted coil has an DC resistance drop. An ESR measurement tool is great

Chris: "I have my little phrases." Me: "It's been 84 years since I've heard him say 'CHNGUS' "

they may say replace the whole unit but i'm like this i'd rather rebuild as it keeps things out of scrap yards and land fills, you do wonderful work Chris and please keep sharing

Couldn't agree more with you Chris. Hopefully this bring more awareness to factory to give real maintenance information.

I’ve been waiting and learning from your videos for at least 3 years and for you to know what Damn Gina is from, does my heart good and have made my day lol.

I thank you for your ramblings. It shows your big picture thinking. Your big picture process has helped me so much. I’m a facilities manager and my property is in the middle of no where. It’s hard to get a company out to us. Following your videos has helped me so much in troubleshooting my equipment! Please keep the videos coming!

Hi Chris, I found your videos a month ago and it has been a blast watching them! I'm a maintenance person for a hotel so these videos help me with basic cleaning and troubleshooting for my ice machines, coolers/freezers, and HVAC units.

I do mostly resi stuff and minimal light commercial, but I have been learning so much from these vids! Thanks so much

I don’t even work in the HVAC industry- ok I have a electrical / electronic background, but I understand you just fine. Keep doing what your doing buddy, I’ve learnt more about your industry since lock down than I ever thought I would just watching your channel.

Finally got AC in the home. Thinking very fondly of all fitters and technicians right now - been staying indoors for two days just to enjoy the cool! 💙 Sleep and work focus improved noticeably.

I don't always make it to the end of the rant section, but I always make it to the end of the technical things. I'm not an HVAC person (at least not in a professional capacity), but your troubleshooting skills are top-notch and that transfers to a lot of things and makes these videos excellent.

Kindness is always something that is more needed for everyone. Kindness starts with me and I have to hold myself personally accountable each and every day. I respect those who show me acts of kindness and try to return my kindness to them. If you don't show me your kindness then I will try to show my kindness to them.

Always watch to the end. I've been in the business 40 years and still pickup tips & tricks from you. Great content brother. I use your vids to train my guys.

I'm grateful for these videos man... I've absorbed so much from your "ramblings" while "talking to yourself" about topics I've always wondered about 😁... I hope you keep it up... Ignore the pedantics.

Gonna say straight up, as a residential tech, no tune up includes splitting double layered condenser coils. In fact, the vast majority of those tune ups will not even include stripping the outside cages on condensers. Realistically we clean from the outside and blow in (and you are lucky to have foam cleaner used), not from a lack of knowledge but because customers don't want to pay what it costs as part of a tune up nor is it usually needed. If people complain about $75-$100 dollar tune-ups they certainly won't pay for $200-$300 dollar tune-ups. That being said, when it is needed based on your tech's experience and/or there is an issue being caused....we do have charges for foam cleaning, for removing the outer jacket of condensers, for completely stripping a condenser and cleaning the outside and inside, and yes even for splitting double coils. So don't be surprised if your tech randomly comes up and brings up a higher dollar amount for a cleaning, and don't give him the "well no one else had to do that and it is working fine" line. It takes a lot of time to properly strip and clean condensers, especially depending on the manufacturer...so we gotta charge for that time.

I absolutely love your videos, been watching for years now! One thing that I continue to struggle with, that I find is never brought up is explaining to the customer little details and making them feel comfortable. I know you can’t record conversations but even in this video, I would love to see how you explained working so long on a unit and realize there’s a slight restriction after the fact. Very common situation that I still don’t always have a good way of explaining and having the confidence while in conversation. Anyways thank you for everything you do!! Keep kicking ass!

Martin is the 90s sitcom you were looking for haha... Love the videos, I've been watching since the beginning, livestreams and overtime shows too, you share so much knowledge and dont hold back in a very grounded unbiased way with no agenda other than helping us techs out here in the real world. Your content has made me a better technician and I try and pass these lessons to my trainees. Thank you so much for all your generosity!

I’m sure he prefaced that statement with “I’ve been doing this 30 years…” I didn’t learn HVAC until I worked for a distributor, and since then I’ve taken numerous factory and online training classes including a NATE certification and your videos contain by far the most helpful/resourceful/useful information out of them all.

You're just so exceptional, your explanatory method is just so simple and clear .

Your correct on the repair vs replace part. I work in schools and if we have to replace certain things it requires we bring so many other things to new code. So we repair as long as we can, until a remodel.

Dude I'm not even in HVACR, like I have a passing interest, and I have watched literally all your videos. it's like background ASMR

Great video Chris! You are the hardest working technician...so thorough and conscientious!

im tempted after watching these and knowing a lot, To setup my own air con for my shed that is a house to some servers. Lots of heat is made in there and needs to be cooled. Now iv watched these for about a year. Id probably feel better setting one up than i would of just watching a video on youtube

of course your video is helping a lot for diagnostic and repair and maintenance, cheers . , i think that is the easiest part at least for me to find the problems, , but at the end of the day my biggest challenge is to confront the customer for estimate and cost $$$, I love that time and I hate that time .

Great Video. I work at a University as a Maintenance guy. I have guys that I call out to service or troubleshot units like this one and your videos are super helpful.

You say your not a trainer but I've learned a chit ton from you. Thanks for the content bro.

First time leaving a comment, but you asked to leave a comment if we made it to the end of your videos. While I don’t ever see myself working on AC units, I find your videos oddly relaxing and informative. Anyway, appreciate your sharing your insights and expertise.

Hey Martin thank you for sharing and love how you teach your community. Love the troubleshooting vids on refrigeration and commercial HVAC equipment.

Holy dust bunny's Bat man! Lol you said " unit needs a little love " Boy you gave it a whole lotta love. ( led zeppelin 's is better though..) it definitely needed. Keep up the great work, nd as my uncle Marino would say " Jimmy if it were easy ,we'd have girls in mini skirts doing it." May he R.I.P., dont think you could say that today anywhere,without offending someone. Appreciate your time with the diagnosis, editing, nd up loading of the video.

Some of the Trane RTU's have 3 row condenser coils. One of the benefits of microchannel is that it's only a single coil. Even mini splits and VRF units have multi-row condenser coils. Here in the NE the cottonwood, which happens in June will plug them up solid. Ice machines definitely take 4-5 hours to clean properly. They aren't the easiest to service or work on. Lots of tubing to remove and little parts and pieces. Cleaning and sanitizing has to be done in separate steps and 30-45 minute cycles for each.

When you started bump starting the unit, my battery backups in my room clicked. It confused the heck out of me! I just happened to have a power glitch at the moment Chris pushed in the contactor. 🤣🤣🤣

Made me laugh haha! “Super heats a bit high, I hope it drops down…” Superheat: *19-0 in .5 seconds* I didn’t realize you had swiped so made me laugh 🤣

We do need more kindness. If we all worked on loving our neighbors and ourselves, a massive portion of the division in our country would not exist. On another note, I finally found the hose wand you use in stock! It’s the perfect setup for me, but nobody has had them for months in my area.

If i ever told my company I need that kind of time to clean a unit they would lose they're freaking minds. The down side of being 95% install focused with way WAAY too much work being under bid.. your videos do help me to refresh my mind on troubleshooting so I appreciate that dude.

Chris thanks for taking the time to produce this videos, I love them and I have learned a lot from them, they really shows the real world of hvac work on the field good for everyone who wants to be a good technician. Thanks your family for allowing you to help others grow in this trade.

I watch till the end enjoy your work methodology. I hope you find some good workers.

Best phrase on this channel “sorry I went off on a tangent”.

I’m pretty sure you are referring to the show called Martin. I enjoy your videos, you explain things plainly so anyone can understand

These videos are gems for the community man we watch them because they help us. You help us and the normal non jealous people understand you make some mistakes but they are so minor in the grand scheme of things it’s almost not even worth mentioning except to just clarify for the ones that don’t know

You are correct. The condenser coil supposed to be split to clean it. The biggest problem I have with older AC units is leaks. I have the hardest time finding a leak on a good working unit.

I am a technician in hvac-r. I like what you do and could see the unit that was being shown. Carrier is a tuff system. I hate splitting the condenser. It a mess to deal with, but when done right you will get high praise by the customer and that makes everything worse it.

I always watch to the end the closing words section is my favorite.

Your statement about needing more kindness is right on! Sometimes it seems like it's in short supply. I think people watch your videos because you are talking to the tech. Guys out there just trying their best to do a job well and it doesn't matter if you mess up sometimes. We all do. Experience is a good teacher. And you have that. It's always good to know the "got chas" before you start a job.

Anyone can learn a lot from your troubleshooting style. Not making assumptions based on prior experience is THE hardest habit to break - Especially when you're getting driven to complete more jobs in a given day. I'm retired, 70+ years old and I learn stuff from you every video that you produce! It doesn't make me any money, but it sure helps me work on my own stuff! And in my experience, you're the ONLY tech I've seen anywhere who advocates splitting the outside coil for proper cleaning on residential systems. I have one 4 and one 5 ton heat pump, and both have dual coils. I haven't bothered to split them yet because I live in the desert away from most industrial and freeway hydrocarbon contamination and the head pressures have never (yet) been high that I couldn't explain. But in your area it would be crazy not to. The amount of hydrocarbon contamination from the freeways alone in Southern California is staggering.

I made it to the end and I appreciate your efforts. Please continue

Martin bro! I remember being sick home from school and would watch it! lol

Good video , you are wright every one makes mistakes out there and no one knows it all. I went to hvac school and your videos teach new techs allot. Thanks

I always watch your videos the whole way through because you are a treasure trove of information and experience. Seriously Chris, you are the best dude

Big thumbs up on not using aftermarket junk condenser fan motors, we have been burned lots of times as a company trying to save the customer company, way better off just using factory parts in the long run

Martin 90s sitcom very funny back in the day thank you for sharing this video Chris keep safe dude 🙂

You said that the short was on the common side of the compressor contactor. If you have a grounded seconday you would not have a short because it's on the grounded side of the transformer. If you have a floting secondary you would have a short. You may have a call back.

yep, i watched it all. in the end you said 'be kind'. good advice. btw, love your ramblings.

I strive to be a great tech like you are one day. I learn something new everytime I watch your videos. Thank you so much for everything you do. 😃

First time viewer. Made it to the end of the video. Agreed we need more kindness. I tip my hat to you on knowing how to fix equipment. Very awesome.

Really enjoy the content, really hope you don't stop..the big picture..thank you Chris..

Love how you had a lot more ...personality in this vid while still being informative , good job !

Hi Chris, I always watch to the end as, I would imagine, do most of your viewers. That rub out on the condenser looked about 4-5mm, soooo luckily it didn't hit the copper. Cheers for all the great videos and the time it takes to edit and do all the stuff needed, Thank you.

I make it to the end of all your vids. I like and enjoy them. Thank you for all the great work you do. I have learned so much. I do 3 or 5 residential ACs a year and your hvavr has given me some tips to help. Again thank you for being you ❤️

Perfect does not exist...... And by the way you are super helpful with your videos..... No one knows every thing.....

To many people go to school for the trades and get taught the correct terms for things butbhave no clue or means of how to repair or diagnose why something broke. Any tech can swap parts... To trully understand how to correct a problem and prevent future problems is what seperate the good tech from the part swappers. That being said contuing to educate your self in your chosen trade will always be beneficial. Great videos

Made to the end thank you for making the videos. I had to replace a compressor on a 21 year old carrier because I could not get unit. I use to live in San Diego I understand how California is . Nice to live but expensive with a lot epa rules.

The big gash in the condenser coil is common on those. It’s from the zip ties holding the coil together rotting out and breaking. Or guys will split to clean them and then leave the zip ties off. Eventually that top pass on the coil will rub out against the top of the unit and blow the charge.

Yup, made it to the end. You’re definitely right on all of it.

I always make it to the end of the video. Great 👍 video as always, thanks for making HVAC/R better with all the knowledge and advices you provide to this amazing career.

You do a great job at explaining things. We all make mistakes but that's what makes us human. You do excellent work on troubleshooting, finding the main source of the issue and fixing it. Great job man 👍

You may not call your self an educator, but you are an excellent teacher !

Well worth watching to the end of the video. Loved your response internet complainers- "shut-up" 🤣🤣

Yes indeed you helping a lot of people…

you are perfect man thanks for your efforts to share your knowledge and experience

18:20 what the heck happened to that panel it looked like it had a meeting with the Hulk and got smashed🤣🤣

I usually find a short over between the panels by the evap coil. I always pull those coils apart, usually no one else does and its always gummed up with cottonwood.

There's no perfect person in the world. We learn by our own mistakes or were supported to any ways. Great job. That's how I was taught my dad said your going to learn all your life just don't give up is all I use that theory . You can read any book on any thing out there on how to do something hands on your going to find out they dont give you every thing. lol.😊

Cleaning them looks like a real satisfying job.

Hey Cris, made it to the end and wanted to say thank you for the videos, even though the teacher was upset I’m sure any one in the trade knows what you are saying and even if it is said wrong we are all thinking it and probably don’t catch it haha. Thanks again keep up the good work and BTW love the march

DAMN Gina! Gotta love Martin 🤣😂

I lost my home 5 ton unit after 30 years of faithful service due to a split condenser coil. Never had a problem, and never took the lid off the condenser. Always kept the exterior fins clean, and the interior looked clean through the fan. When I broke it down for recycling, I found the split coil. Was so disgusted with myself for not knowing, or investigating that.

Thanks. The number one argument with management is how long it takes to properly vlean the equipment. Thsnkd for that statement.

You seem to polish a lot o turds out in CA. Your customers are lucky to have you. In the Midwest they always say “replace the entire unit. It will come with a warranty.”

Fuck the haters man. The information you share via this channel has likely helped thousands. I know it's certainly helped me. And of course nobody is perfect. Just know that you are appreciated bro.

Great 👍🏻 video like always I enjoy your videos , keep them coming thank you for sharing your skills

Ha I'm going to date myself here 😜 nanu nanu! Lol name that sitcom.

Some times we talk so fast we mix words but that does not mean we cant do the job properly lol Some people are just picky. Keep it up fella.

This is why I like the newer rheem RTUs. I take the side panal where the heat exchanger is and block the supply duct. Then run the blower to get all the loose dirt to blow out of the side of the unit.

You're referencing Martin. Great show.

I just noticed there's a spare control fuse sitting in front of the board, which to ME says someone's been just going back and replacing it when it pops without checking for the cause of the problem, and if it was another company servicing it, some of the sketchier techs might've tried bridging out a fuse to troubleshoot.

Don't fret the small crap. You know what you're talking about and doing. I find this interesting how these massive units work. I'd like to see a complete unit swap & set up.
