I like the 'drive-to' style opening. Nice change from straight into the problem.
I like it, gives it a ridealong type of feel
@Egon Freeman 30 seconds of dialogue in the beginning doesn't change the "hard facts" of the totality of the situation.
I’m not even in the HVAC industry, but I love watching your videos because of your approach to how you troubleshoot things. It really can apply to any industry. I love seeing good honest people out there solving problems with integrity. Keep up the good work!
Thank u for making vidios frequently, I learn in every single one.
Send the breaker to AVE or Big Clive for a proper tear down.
If I were in your area and needed commercial AC work done I would be *very* happy to have your shop doing the work. Higher praise I cannot give.
you have to limit your liability. you change the breaker and some unforeseen thing electrically happens even if you didn't touch that part is your problem according to the customer. I love the fact that your concerned about the heat and doubling up on technicians. there were many times i was on a job with extreme heat and wish there was someone else there because of heat stress.
best and most obvious advice i should of known "know your own limits" the amount of times i skipped lunch to do a job and stressing myself out just to come back the next day
Idk why, but your videos really help with my anxiety in the morning before work. It helps me stay calm and gives me a good positive mindset for when i go to work and i appreciate that
Man I don’t no anything about hvac But something about your videos are so relaxing I know it’s weird But I really enjoy these videos
With our heat wave, my manager is saying just to get it to run and move on. We cant spend much time on a unit because we are getting hammered hard with calls. But, we revisit systems as we are backing off on the calls now.
I just started as an HVAC apprentice so I found your channel and honestly I'm learning so much
Not to mention if you change the breaker and then there was an electrical fire. You would be suspect #1 no matter how sure you were it wasn't related to your work. Let the guys with the certs and the insurance deal with it.
Especially if he upped the breaker size without the proper wiring size being upgraded. It's a 30A breaker for a reason.
Thank you for posting this, iove to see integrity at work.
I've had a water heater breaker fail from simply turning it off, so I could pull the water heater and do some plumbing repairs behind it. Hook it back up and only have 120v of 240v of the circuit. Told the customer they needed to call a sparky and he said just like anything they go bad over time. Constant vibrations from power going through it wears it out over time.
Sorry for my poor English, it's not my native language.
Nice video. Excellent intro, it's nice to see some of your scenery as well.
Good judgement on that breaker. You're a HVAC guy, not an electrician. I used to work as a tech on electric vehicles, and if it is connected to the car I would work on it. But if it's not mobile (ie. a charger/charging station), that's for the electrician. And I would assume it's the same for you. You're licensed to work on anything from the disconnect switch and onwards.
And it's an important distinction, because if you touched it, you own it.
Another excellent video, Chris. And wow - those returns were something special! With that much grease flying around that building might just take care of itself one day. Amazing they can't see what is building, but it happens all the time. Every time I see them tearing down a 20 year or or less restaurant building I shake my head - often is more economical (and safer!) to just knock down buildings that aren't maintained. Blows my mind yet still see it fairly often.
"Tweaker got up here and broke the drain line"😂 How many times have you guys found shell casings, mini booze bottles etc. on a roof??
Work smart not hard ! That explains why you had the electrician replace the breaker while you did all of the other stuff that needed to be done and because of that you also didn't have to make another trip back to that job! You definitely put your thinking cap on ! You also saved the customer and yourself money as well! Thanks for a great video!
I will never get tired of the videos! Always learning. Thank you for the effort on making videos while doing the job.
As an apprentice refrigeration mechanic I have gained a lot of knowledge from your videos. Thank you 👌
I've changed breakers, but I don't believe it's hvac. That's the electricians problem. Our power stops at the disconnect. There's too much liability with playing in a breaker panel that im sure your business insurance wouldnt cover. They get paid to do breaker panels we don't.
it is basic
Changing breakers is too easy to tell a customer “sorry. Call the electrician!” As long as you can kill the main feeding that panel or sub-panel it’s fine. As long as you aren’t CHANGING a circuits load or adding a new circuit/load you have nothing to worry about. HVAC is the skilled trade of skilled trades. We are electricians. We are plumbers. I wouldn’t pull new wire to a disconnect, but changing a breaker is too easy.
Paradoxical Nightmare like I said, if you can shut power off at the main breaker or breaker feeding that subpanel. I work with a lot of 3 phase power, VFD’s, starters, and breakers IN our equipment. What about those? Call the sparky? I can see residential guys drawing the line there, but commercial/industrial guys usually end up having to do it all.
Are you legally allowed to in your jurisdiction? It's against code here.
It's really not that hard, it's really hard to F a breaker change out. But what ever, that's just me I would have done it and made a tad bit more money
Great customer service!
Like the opener to the video on this one, gives a nice vibe of how your day goes. Also glad to see you're sort of starting to open up more and not acting as serious all the time like in some of your old videos. Still the best diagnostician for HVAC I've seen so far!
I was curious about that breaker panel and why, as you wondered, the breaker failed. Apparently, from the little Google searching I just did, Challenger breaker panels and breakers are known to have issues, much like FPE panels did years ago. From my reading, it appears many insurance companies will not write polices on homes with Challenger breaker panels.
Another great one! Thanks Chris.
Gotta love the desert sunrise. When I was working in Palm Springs I love seeing all the red blinking lights on the wind turbines.
Every area is different. I do several bolt in-breakers every year, power off. I try to use the same MOCPD value for the breaker and the fuses, if someone mounted fuses at the unit. The ONLY time you need fuses these days is when the label specifies "fuses," and you hardly ever see that, since most breakers now meet the HVACR breaker standards. Also, when I can't clean a coil with green cleaner, I go right to the Nu Brite. You have to cut it down to 5-to-1 in a sprayer, but it makes easier work for greasy and flour-bound (bakery) coils. I also lean some panning into the condensate pan to prevent all that foam from going down into the return, and I keep that under control with a large shop vac. The worst coils are restaurants where the RTU is right next to a grease exhaust fan. Then, they deny the quote and I move on to the next customer, whistling down the lane.
I wish our road crews used their time like this! Wouldn't take nine months to finish one street, I bet.
Efficient and responsible as always. 👍🏻
From the unit fuse size vs. Breaker size. The breaker is to protect the conductors at 125% of the MCA or FLA. The unit disconnect fuses are serving for shorts and faults (overloads) near the motors. So long as the breaker is rated for HVACR equipment it should not have problems nuisance trips or premature failure.
I’m changing a breaker in a refer rack, but that’s equipment. RLA is 13, breaker is 15. A rare 105deg day caused it to trip just from the sun beating down on the control panel. Has 12 gauge wire, so a 20 is coming. 13 is over 80% of 15.
Excellent customer service on your part!!!!!
Great job again like always and great video
Your truly a great guy who cares about his people
Do you remember if the breaker was warm to the touch? I recently had a scenario where I turned off a breaker at the house to replace an outlet that had went bad. Flipped the breaker off, replaced the outlet wire for wire and flipped it back on. Simple enough. About 2-3 days later i started noticing burning smell coming from the breaker panel. Felt it and it was super hot. Flipped it off and called an electrician. Got the breaker replaced and had him inspect the panel just in case something else was wrong. Turns out the breaker just up and died randomly from his point of view. Could have been anything from a bad set of contacts all the way up to just age since everything in that panel was from the early 90's. Might have been what happened here. The breakers are either just getting aged out or sands nuking them.
Sand is an insulator (think Glass or ceramic )so that will prevent the flow of power in the first place
@@punker4Real yeah but fine sand will just make a sparking distance between contacts, i am afraid you need a lot of sand before big contacts are fully isolated.
Love the videos!
So much stuff for me to comment/compliment on this video. First off, reason number 2 why I don't live in California, if it's over 65⁰ at that early of a sunrise, I'll be a puddle by noon. Haha. Great video Chris.
Smart move not messing with the breaker. Electricians will tell you that a simple breaker sometimes turns into a entire panel replacement and you didn’t just sit on your hands while you waited so the customer got their money’s worth.
At the end again, good job
Nice service again ! always going that extra step ! Big Picture .
This channel is amazing
Love the great videos keep it up
Got my hat, looks and fits good👍🏽
That was cool driving past the wind turbines
You made the right call having a electrician come in to do the breaker. Just because you know how, or can find the part doesn't mean you are right to do the work. I know some guys will say ohh 'it's hard to screw up a breaker' or 'its extra money'. But at the end of the day, if you aren't licensed to work on distribution panels, then you cannot work on distribution panels. It's not just you not wanting to do the work, its the licensing and regulatory agencies not wanting you to do the work, if they did you would also be called an electrician. Even if you did the work right, if they screwed something up, or someone else came in and messed with the panel without saying anything and it hurt someone or damaged property and you were the last one to work on it, it's on you. Your insurance is not going to be happy either.
Just because I work on AC systems in cars, and work with HV systems in cars, doesn't mean I can go jump on a rooftop unit and goto to town. Just because I have done electrical work on 480V air compressors, doesn't mean I can go hop on over into the distribution panel and start working on stuff over there, it's not in my license. In today's society we are litigation happy and EVERYTHING has a CYA policy attached. Do not give someone else a reason to come after you. There is a reason you don't service non-serviceable parts, there is a reason you stay out of things you aren't licensed to work on. Not making an extra buck and having internet tough guys call you out doesn't matter when you get to keep your job for tomorrow.
Good for you for knowing your limit with the heat...My coworker based in La Quinta sent me a picture of his car thermostat on his drive home to the IE and it was freaking 121°F. The desert is no joke... I am surprised you didn't setup an ezup on this visit, though. O.o
Great video. You would be an awesome boss to work for.
Trying to remember the chemicals i used when cleaning coils, its been soo long since i did work with AC stuff.
When i was 15 i used to go with my dad during the summer and clean condensers and walk in coolers back in Las Vegas.
The chemical he had he would mix it with half a gallon of water and put it in a portable pump and sprayer.
When you spray it on the coils, 5-10 minutes later it would foam a brick wall and basically Push all the crap out the coils, including grease removal. Rinse it off and looked like a silver new coil every time. I dont see that when using the Viper products, but it seems to do a pretty decent job for most part. The chemicals that were used you couldn't smell them from what i remember.
Hi Chris same here in Aussie we aren't even aloud to even open the electrical panel, we do but not aloud to by law,anything from isolator,disconnect as you call it,back to the board or panel, no can touch.
Awsome troubleshooting
Really hot days get a visit at dawn and off the roof by 10.
7:07 Dinner time!
Wow.. your the man for making that evap look about new. Secondly.. safety has no price tag and for those that question billing do the job. Lastly.. from a disconnect we are responsible.. breaker to disconnect is all the electricians. Thanks for sharing and be safe.
Great job! N yes we're not superman. We work hard and can't kill yourself in that heat.. thankfully I have an electrician on site on my job. But still never enough time
thanks brother
Hi thank u so much
2 hour response time is actually really good, as an atm repair tech, we average a 4 hour response time just because we have a lot of calls from multiple customers at all times, on a rare occasion, we will get that 2 hour or less response time, it just depends on where the units are located and how many calls we have, i remember this one call, it was a slow day, just one of those days when the customers wernt breaking the units, i was sitting in the parking lot where the unit was located in the last 20 minutes of my 1 hour lunch when the call came in, quickest response ive ever had
good job
I knew you worked out here. Saw you in Pd a while back. Goodluck my guy be safe out here
Yeah i am based out of Riverside but have a few customers out there... im out there maybe once a month
That's great, wish you best man!
Not too bad. You have the nice weather most of the time. I'm out of coachella, for about a year I was working all riverside county and man did I love it. Payed drive time from 5 am to 8pm was the life haha
I do like the opening of the video!
Hope you're staying safe with all the crazy weather. Friendly reminder to replenish your sunscreen if you have not already!!
Nice video
Your right 100+ degrees not working too long in heat
I wish my boss saw things the same way you do.
8 hours on a hot roof, can you look and so? Man they crazy as hell
I've said this before, but you made the right call in not working on the distribution panel, for all the reasons you note, but also fault currents are quite a bit higher at the panel, and you really should have arc flash PPE to work on it. Also, don't second-guess yourself - voltage drop across the breaker means the breaker is defective and needs to be replaced. Just like contactors, they go bad. Any appreciable resistance across the contacts creates heating, which accelerates oxidation, which increases resistance further in a vicious cycle. Even if it looks okay externally, the guts will be baked. She's dead, Jim.
Good job chris,always know your limits. I don't spend more that 2 hours in the roof in this heat breaks are essential to keep working up in the roof, good video bro 👍
I will discuss this on my livestream this evening 8/31/20 @ 5:PM (pacific time) if you can’t make the live show no worries as it will post as a normal video on my channel afterwards. ruclips.net/video/c9o-iBcLFHs/видео.html
Always check for hot joints at the bus to breaker, and breaker to wires before condemning the breaker 👍
Under load, the IR camera might have provided interesting specifics on the breaker failure (connection related?)?
Thanks
Lol. That ain’t greasy! Go to FB to see the one I had to deal with today.
Tshirt slogan idea “something’s funky here”
That's right with those outdoor temps enough is enough live to make money another day also good call on the breaker if something goes wrong with that panel it's your baby
Sunday mornings with Chris...what could be better? ;-)
If the main breaker is on an aluminum buss bar. Oxidation between the buss bar and the breaker is a major issue. I had one elderly lady that had circuits that would blink just like kids were flipping the breakers at the meter. It did it while I was there fixing something else. I pulled and reinstalled the breakers a few times in her apartment and cured this years long issue.
Oh boy aluminum buss bars, I sure hope you put a little bit of anti-oxidation paste on those terminals. Might not do anything but it makes me feel better knowing it's that much harder for oxygen to get at the aluminum and form that non-conductive sapphire layer.
These units run 24/7, can you imagine if our cars could put in the run time these units do?
MY car has an electrical A.C system sooo awesome it starts getting cold in 30 seconds or less ...(on full BLAST it's like one of those walk in coolers SO cold you can see your breath in the middle of a hot 110F summer day.) (mechanical A/C belt driven ) are pretty slow to cool down and could take upto 5min - 20minto fully cool down a car(or not at all)
it's a 3.5KW system(that is more then your house uses). for only 150 cubic feet.
it's right up HVACR VIDEOS ally if I need work done.. hope he likes working on a 340Volt DC system :D
better bring your hamburger ear muffs..
And another thing... It would speed things up if you could tell the electrician the brand of electrical panel in use so he could come with a proper replacement. Not all brands of breakers fit other brands of panels properly; some breakers can literally fall out and cause dangerous arcing. Simply replacing the old breaker with the same brand that's not the same as the panel brand is an invitation to more trouble. The panel slots could easily get damaged by an ill fitting breaker.
Dont beat yourself up over calling a electrician to change the breaker, you actually saved your customer money. I wish every kind of tech had the same thought process as you
I like the intro
Love yr vids dude for us Aussie viewers could you do a temp conversion say yr temp F/our temp celcius,cheers
Lol
Ole buddy thinks he's a sparky I love it
Most electrical wholesale places only cater to single phase it's actually harder to find one that carries commercial three-phase equipment I know I've tried to hunt down 3-phase Breakers before it's a guessing game but if you're in need of something commercial and it's rare Orange County circuit breaker is usually my go-to place
Thanks for the videos you make. I like to watch them to pick up tips.
I ordered Field Piece Probs and started using Measure Quick after watching you use it so much. I’m still getting used to it but so far so good.
Question, do you have or like the Red Fish meter to link up to Measure Quick for electrical diagnostic? I don’t have one and I’m back and forth weather to get one.
The kitchen ac is always down. Between me doing hvac and before hvac working boh . the one thing i learned is the kitchen ac is down
You should get a worksite umbrella, pretty nifty.
Damn, mad respect for workin' in that heat. How have you been doing with the fires? Hopefully the smoke hasn't been too bad for you.
If you'd given the power to the 2nd unit the once-over during the previous repair, the customer would have simply replaced the breaker and moved on. As it is, they got some much needed maintenance. Good choice to stay focused on the 1st repair on the 120 degree day. Easier on you, and the customer gets a much more thorough job on both units. (Not to mention the common drains!)
Here in our country Philippines if you are AC Technician then you are a electrician too..
That is a rooftop AC..
Great call on having the electrician replace that breaker. We need to stay in our own lanes sometimes. I do have a question, why can't you just let the condensate flow on the roof? Where I work and live we just let it dump on roof.
It's something to do with the fact that they have separate sewers for rainwater/drainage and sewage, and the roof drains go to the rainwater/drainage sewer but the A/C condensate water has to go down the "sanitary" sewer line, according to the building code.
At least that's my understanding of it from watching a large proportion of this channel's videos.
Cause it's California. The condensate has probably been know to cause cancer and must be drained properly.
simple answer: overtime concurrent drain water on the roof eats up the roof membrane and the roofers warn the landlords building owners about it.
you could give a price to route drains to gutter though.
Hell yeah take care of yourself and your employees. Heat stroke is dangerous, and if the customer doesn't do the preventative maintenance you recommend, well then you can only do so much in a day in those kind of conditions
You did a great job. Do not call the plumber. The previous one did not even size the drain lines correctly. 2” line would be close enough to drain all those RTUs.
Sub 900 views! Liked the driving intro thingy. Very scenic.
I know where those wind mills are, damn it is going to be hot this day. Hope it was ok for you.
Breakers will go bad much sooner if the tenant keeps using it as a primary on/off switch instead of using the switch or disconnect at the device.
I've heard that for certain breaker panels you can get "switching duty" breakers that are rated to act as a primary on/off switch, but that's just something I saw on the internet so I don't know if it's true or not. If it is true, and that breaker panel is the right brand, those switching breakers are what is needed.
nice video again, i was going to ask you why you didnt change the breaker, why wait for the electrician, but i read some commnetraries and i know now is because insurance stuff. Right here in Mexico is kind different.
Not clear on location of breaker panel...still have sand in an interior distribution panel?
As always appreciate the walk along and explanations...old dog here still learning new tricks thanks to you kids and youtube!
The breaker panel is on the outside of the building...
I know we’ve all blown out and cleaned many of drains. Curious, since they all run into a common outlet at mop sink, how come you didn’t use shop vac at sink and push some water thru at same time to possibly make it quicker and easier?
Great job on that evap btw it almost looked like new after!
Customer wants stuff fixed pronto, but don't give the proverbial rat's ass about maintenance to avoid chronic breakdowns. I say screw them!
And, yes, don't take on stuff that you are not licensed to do ... if anything goes wrong in that area you're then liable and that would not be a pretty situation.
Yeah, especially in California. If you change something you are not certified to do, you might be in a real trouble later. I would stock some common breakers for this panels in the car tho, so you don't need to run to shops tho. Just like you would have contactors, fuses, MCBs, etc in the car. Even if it requires an electrician to replace it, having one on hand can be beneficial and save time.
Even if he would have certification and qualificiation, it is still better left to do to somebody who does it daily. There might be some unusual problem, or you might need to pull out some other documents to know where wiring is going, know rest of the building circuits, have specialized meters, proper tools, PPE, etc. etc.
The wire going into the breaker could have been under torqued or over torqued.
If it was under torqued then it could have been making loose contact. Which would lead to excess resistance, leading to heat, leading to more resistance.
If it was over torqued then it could have gotten damaged internally. Which would have acted a lot like under torque, only internal instead of external.
Or it was just a minor manufacturing defect. Which again would have acted a lot like over torque.
Sand, kitchen grease and water aerosols will age breakers as this did with the switches and controls in the older consumer entertainment centers. The kitchen aerosols plus lint and dander from a non-ventilated home kitchen coated the electronics in the units attracting cockroaches and other vermin. I'm a retired electronics technician. We both service units plugged into the mains panel. The other side of the panel or wall sockets, different world. That's for electricians.
Where did you get that magnet strap for the fieldpiece meter?
