Critical System Diagnosis for Residential HVAC

This a RAW Kalos meeting where we talk Critical System Diagnosis for Residential HVAC. We cover proper diagnosis mindset, and focus especially on compressor diagnosis and how to make sure you aren’t telling someone they need a compressor when they don’t.

People tell me I carry a bad attitude and they are right. Trying to correct sum of my faults. You are correct sir. Oh the shit that I have been through most people wouldn't last a week in our shoes. But when a man has a thing that was everything in his life, he wants it back and would do anything to fix it. CK

I feel like I’m learning so much more watching this channel than I did when I was in school.

[@jasonjackson8191]

Real world scenarios. I’ve been out for 21 years, I thrive on training, I love this channel!

[@HVACRTECH-83]

Because there's no qualifications needed to teach apprenticeship courses, alot of the teachers are shitty techs just looking for a little extra money to support their drug, alcohol or gambling habits.

[@Stuart68505]

So true for me as well. I really benefit from the instructors insights even after years of troubleshooting HVAC systems.

20 years experience in the field, and never have I worked for a company that would take the time to explain like you do.. great job with your videos, and if I were closer to yall I'd definitely come apply for a job lol.

[@kainivester9187]

I had the awesome opportunity to personally meet Brian and his employees. If I lived in his area l would work for his company. All his staff was really happy working for him. He's trying to better the industry, and the super technicians that can do no wrong and walk on water are not helping the industry as a whole. Thanks Brian for taking the time to help us all grow in the industry.

[@donio71]

Man,I wish I had somebody like you to teach me when I started the trade.its amazing in how much care about the trade,and how you like to teach 👍🍺

[@kenneth6731]

Yup, all ours did is say "read the book, it's in there" It was like taking an online course, but at the school. On the last day of class, only 4 out of 35 knew the difference between series and parallel.

[@HVACS]

I appreciate that!

[@972958]

Bro I didn't know shit leaving school but ever since I found this channel I'm literally on it every single day even rewatching them. Great content couldn't be more grateful for Brian and others at kalos and hvac school 😭

[@Phil_Scott]

Great video, your opening and closing comments about intent to be certain and caring are crucial. Its the missing link in many cases. I am 80yo now, retired mech engr and HVAC contractor... started with my own small shop, built it to 27 men, and large systems in the 50 to 200 ton range.. sold out in 1986, began consulting nationally, then for major firms on billion dollar projects, testified before congress on the ethical issues related to our nuclear weapons plants. It can be done by just the intent to understand and learn more and more each day and by always looking to involved in the next higher level. Dress and personal appearance is key however...very clean, very well groomed, a manicured look almost... nice crisp shirt, snug pants, good boots kept well. Can easily double or tripple a mans income. Being cool and sloppy cuts income to base levels or lower. One time I had the large vice on my truck chrome plated and polished with a polished brass plated clamp bar... mounted behind the cab. I raised my prices to be one dollar higher than the most expensive outfit in town... my business doubled.... and.. you have to care.. alot about being 100% correct. No guessing. That is what makes you sharp... and that brain function will serve you well deep into your 80's. Sloppy people degrade much more quickly than that.

[@strictlylaborhvac5141]

Great advice 👍 as a veteran in this field, your words are on point, 1st impressions last a lifetime, and your work speaks for itself. I've seen installs that mustve cost $150 in labor, and I've seen installs that go for much much more. Do it right the first time, and you'll sleep well at night..

[@WreckingCr3W2]

Very interesting!

[@tycobb8621]

Yup, wearing “snug pants” has certainly doubled my business…with the single moms 😂

[@newmoon54]

Great comment!!! I'm 71, started out in 1977 working in Central Florida area. I was super-hungry to get into, and then own my own company way before going to school for HVACR work. My friends thought that I was crazy, at least some of them! As you said in your comment, dress seriously,, look serious,, behave even MORE serious! I had two service/install. businesses one on Long Island, and the other where I live in Wilmington, N.C.. I also was a service tech. in the NBC Building, 30 Rockefeller Plaza, along with 3 other techs.. we serviced all the studios and about half the offices. I really enjoyed that situation, except for the commute to and from Suffolk county, Long Island! LOL!!!

The diagnostic process is the diagnostic process, regardless of field. This is a great articulation of the proper mindset and thought process needed to do a job correctly. Well done.

[@derekmc9580]

That is crazy. A lot of guys would cry about the meeting you just had but I take advantage of any training I can get. The amount of training and the huge tool stipend you give your guys they should be on point. Just having you around and having your phone number I would be calling you if I’m stuck In a heart beat. Even if they cant call you personally the service manager should be available.

[@HVACS]

Haha... thanks.. they can call me but I’m pretty mean phone support honestly 😂

[@philochristos]

It's good to know technicians are being taught ethics along with skills.

Glad to help!

[@HCheatNcool]

Great video. I had a bad breaker one time on a heat pump. In heat mode it tripped out every time the heat strips came on. The strips checked out so after a lot of head scratching we figured out a weak breaker

[@josephrostkowski674]

If Brian was a service tech no company you would make money. There'd be so many cases in every house that he would have just changed out a small part because he was being honorable. I hope train carrier or York don't get a hold of this video because I don't think they're in business for us to change out minor parts or troubleshoot. They love when it requires a new install but thank God for people like Brian f****** intelligent and passionate and knows his shit.

[@flybyairplane3528]

Joseph, odd you say that, I had worked for a company many moons ago, then 1. Day, I was told That I do NOT CHANGE ENOUGH PARTS, so I said but how are the callbacks ?

best hvac school , and its for free , thanx brian grttz from the Netherlands

[@BrunoP44]

Brian great stuff with your team. If I can just add a bit of opinion or support on your perspective verses teams perspective. In my experience when doing a lesson its always worked out better when I hold the room like a baby verses your approach in this lesson . You were aggressive, boss mentality , and border line rude to the guys . Yes we hvac guys have thick skin. But you are a senior level tech and instructor in this moment . If you want the max information retention rate it is best done with Love verses fear as you inadvertently instilled into the lesson. Learning needs to be serious fun like learning to ride a bike and the joy of succeeding afterwards. If your team leaves that room and someone felt as if they got scalded you are now teaching thru fear . I really like all your videos and appreciate your time . I will use your videos for training and relearning myself .

This message is critical. Misdiagnosis should hurt because our individual names as techs have value to us, simply as a matter of personal pride in our workmanship More importantly, that personal integrity IS what keeps clients coming to us rather than someone else... which IS what pays our bills.

Hoping to get a response back. I noticed when y’all were talking about recovering Freon and weighing it you never talked about performing a pump down test first. That is faster and cheaper than recovering the Freon and charging the customer for your time. Close your valve to pump the Freon down to see if the pressures change.😵‍💫

I love this video. Watching this is mandatory training for my techs. I also picked up on Brian's frustration as an owner. Been there dude!

[@workinprogress4579]

Hey, Brian. What do you think about trying to pump the compressor down if you think it's not pumpiing correctly? And if it does pump down, when you pull disconnect, should psig rise, or stay steady? SUper great video, man. You answered some of the quuestions I had. Than you!
