Got to thank you Chris. Watching your videos has helped me tremendously. I never have been much of a refrigeration guy. It was sporadic calls. Nowadays im getting a lot more refrigeration calls. I have gained a lot of confidence ( not arrogance ) and knowledge by watching, paying attention and thinking about how the system works and the components being used. Happy to say every call I've taken since i started at the company i work for ( 1.5 years ago ) has resulted in a successful repair with no call backs. Thanks for sharing what you know.
I don't work with this industry at all. I drive a tow truck. But seeing how your world operates is always fascinating. I've been watching for years now and I'm loving it.
I drove a tow truck for 10 years, I now dabble in hvac(facilities maintenance) and am taking a course on it as well. Its never too late.
In this channel we get : Tech tips, service advice and psychological terapy!!! 😆 😅 😂 🤣😆 😅 😂 🤣
Great video Chris, love the outros. It’s just as weird here in Northern Ireland, craziness to a brick wall, hoping to get my new apprentice to watch your vids so I have someone to share my understanding of “big picture diagnoses” with 🤘
I'll take your fall/winter over Jersey's any day! Keep up the good work. Your work ethic is something to be emulated by technicians everywhere.
After working in multiple kitchens over the years, and seeing different Walk-ins. watching your videos really gives me some perspective on which kitchens really look after their stuff. Most kitchens with constant walk-in problems was due to defrosting problems and the tech they sent never took this level of attention and detail to do this level of work you provide. Dude you are awesome. Looking to solve the next one on my own hopefully lol. Great videos man.
I don't do AC, but I've been watching all of your videos for months. What I love the most is that you keep it real, make mistakes and own them, and alwasy strive to do better. I do the same with my work. That is all we can do. Keep striving. Keep learning and improving. And, doing all that while maintaining a positive attitude and outlook despite work and life's many frustrations. Thanks for doing what you do.
Man what an outro! So simple but so wise. The world really needs kindness right now. Depression and anxiety are so widespread after covid
I've unsubscribed a few kinda dorky channels... but yours will NEVER be unsubscribed. Great video Chris.
Those of us in the midwest would be happy to send ya'll some cold, so you don't feel so left out. 😃
Keep your cold we'll send you some heat from our Santa Anna's. However, we here in SoCal could use some of your rain perhaps..
Your talk towards the end was Beautiful. God Bless your dedication towards the industry and the advice you share.
i know you probably won't admit it, but i say you are the best, not because you know everything, but because you don't know everything, and you know you don't know everything. when you make mistakes, you own them, and you put them them in the videos for others to learn from. and you are giving your knowledge out for free and asking virtually nothing in return. yes, you are the best. i'd rather hire you to work on something that i know you've never seen before than i had hire someone who deals with it on a daily basis because i know that you will figure it out, you will fix it, and it'll be right. i can't trust the guy that does it everyday to do that, that's just the world we live in these days.
Hi Chris, in a situation like this, bungee cords would work wonders on holding the motors, so you are not putting too much strain on the wires. Just a thought. Great video as always. I'm not in the industry but I love learning about new things. Keep up the great work!
Hello from Wisconsin!
Not in Refrigeration. I. T. but operate by the same principle. 60k foot view, same as you, took me to where i am today as well, you are so so right. BIG PICTURE.... salute.. nice work
I share the love every day...
As a customer, sometimes we give those late calls because #1 were not sure if the equipment is actually going bad or not until more than a day passes by with the same symptoms and #2 we have so much other stuff to do that we forget to check again.
Absolutely love the end of the videos, keep it up man!
Another great video, I like how you keep your cool especially when frustrated.
Thank you for these good words at the end of the video!
Good fix, and I agree with you on being kind. It costs you a few seconds but it helps both of you. Keep up the great work, thanks for taking us with you!
I just wish chris was my boss back in the 90s. As I would have gotten better training as a newbie back then. Today , I have gotten back in the field . I was given door back in 2009 and I am happy that I was given a chance to get back in the field this year. Boy, do I have alot to catch up on.
Good job Chris.
You’re a good dude, Chris. Kindness is key. All we need is love man!
Loving all the love messages. Much needed reminder, thank you.
Great video my west coast utube friend! I'm in Philly n I'm not looking forward to another winter. They absolutely blow as u get older. Snow was fun when u got off from school but working n driving in it is no fun. I don't mind so much except for the rookies out on the road concern me. Stay safe n positive 🙏
Good ol’ beacon II, such a love hate with those systems. As long as I don’t run into an EEV issue
I bought one of those wands at Loews , excellent purchase, thanks for letting me know where to get one.
Hi Chris. It’s great to watch all of your videos
That unit did look like a few bad crimpings.
And my problem this week is that I don't know if my workplace will be running or not in the foreseeable future, and it's not economic issues, it's mining permit issues.
Great video
Hi chris. a tip. Dont insulate the drain and let the drain heat run all the time.
Connect drain heater to defrost heaters, and run it together, no insulation on drain pipe. Works best.
also door switch which disconnect fans and solenoid.
Good find with the wire.
Other tip , i know the frustation. but i tell myself. they pay my overtime and im gonna take my time , and enjoy my work. Get into that mindset _D
Have you ever got to a freezer and it's so badly iced up that you just tell them to empty it and I'll be back tomorrow? Great videos, I hear your voice in my head sometimes when I'm working, " big picture "
Great little vid ... Thx for sharing ...
Thanks for. The. Video Chris. Always. Enjoy watching.
Nice video
Another great 1 👍👍👍
Going to do this tomorrow in Ft Lauderdale Beach. Tip Always bring a jacket, waterproof gloves and waterproof shoes! Still have not got full feeling in one of my fingers from doing defrosting going. Lol
Awesome video. Keep the videos coming. Great end to the video also.
I noticed that it started to ice up on the return.
Quit often machinery will develop a temporary fault that clears itself given a little time. So not calling as soon as there is a problem is often the best approach. I don’t say that this is best for refrigerant but it will partly explain why you don’t get immediate calls, not to mention that if they are crazy busy a service call may get a lower priority.
Yay new video
I’m always rolling up my hose with a rag in hand so it’s not dirty. Glad to see I’m not the only one doing that. But I got hired on as a refrigeration and air conditioning tech for a company. Any tips for the switch from resi to commercial?
I've got so many questions about that Larkin heatcraft set up
Send me an email I'd be happy to try and answer them hvacrvideos@gmail.com
Plenty of work to do. No sense in making more work thru sloppiness. Good job!
There's something therapeutic about hosing a roof off on a sunny day. 🌞
🍺🍺🍺🥃🥃🍿🎯
Stay safe.
Retired (werk'n)keyboard super tech. Wear your safety glasses!
I like to use a pump sprayer with hot water. It cuts the ice better and its lets messy
Awesome 📹… what’s the link to your water hose wand ?
I have been looking for a small leak forever on this system. walk in cooler takes 8 or 10 months to warm up. found the leak at the TXV 1/4" Bypass tube where the brass tube goes into the brass valve noe the braze joint micro bubbles after a long wait and small beeps from leak detector.. it was a Major pain in my a**.
I have this little steamer that I used to de-ice my A-coil...I am not in the trade, just curious if that might work for those no water, difficult situations.
i see that you test amp on heater and i dont think low amp is heating coils and i have seen few electric heater burn out after amp dropped to 0 other still 2 amp
I have a big tote I toss under the evap to catch any drippings.
Could you touch more on what goes through your head when your looking at a frosted/frozen coil? Like TXV frozen - low refer/bad TXV… or top frozen bottom isn’t… etc etc. I know nothings means this or that is definitely the issue till you inspect stuff. But what does the look of the frost tell you to check first?
Thanks Chris!
I will discuss this on my Livestream this evening 10/25/21 @ 5:PM (pacific) on RUclips, come over and check it out ruclips.net/video/jOQsSqJH-mw/видео.html
every time I'm on the roof, i cant make a good connection to my probes in the box. i use the same ones you have. what's the trick?
👍
Hey Chris, love the video. I used to use the wand on my hose but got tired of finding a hot water source. I have a steam backpack now and it works so much faster than the water. What are your thoughts?
I've never heard of a steam backpack, do you have a link?
I'm also interested in seeing a link to one.
Have tried everything from a hot air gun to the brazing torch, defrosting is just nasty business
I haven't seen any units with pump down here (aust), I assume it's pumping down so the heater doesn't cause gas degrade from getting to hot? Or is it because the lowside pressure would climb to high? All the units I have worked on here just stop the compressor and fans, then energize a heat element that is either on a timer or a timer/thermostat combination.
proper systems in the EU simply shut off the evaporator fans and activate their 4 way valve and just heat the evaporator. crazy fast defrosts, the compressor keeps running and its 5x more efficient.
@@SupremeRuleroftheWorld all air con have 4 way valves here, never seen a cool room with it, but I agree it works on frozen ac units. Idk if Americans would know what a 4 way valve is though, they have furnaces instead lol
@@Combat.Wombat.official it depends on the system but i recently installed several that used 4ways to defrost and from our supplier i hear its basically the new standard for a while now.
@@Combat.Wombat.official In The U.S. we have heat pumps in mild climates and furnaces in colder ones. Walk in Freezers can have hot gas defrost with a 3 way valve or electric heat defrost. Walk in Cooler only have air defrost. Only heat pumps have 4 way valves (reversing valve) here.
@@SupremeRuleroftheWorld In the U.S. we only see 4 way valves on heat pumps. Some walk ins have a 3 way valve for hot gas defrost.
What is the amp reading of that heater normally why the ice is accumulating in the coil?thanks

Is it not an issue that one of the Heater is pulling 1.79A while the other Heater amperage was 3.41A?
The coil heaters and the drain pan heaters have different lengths and different resistance
I'm fairly comfortable in saying that poorly-crimped wire was the problem, and that the unit iced up simply because the heaters never got powered. You wouldn't have an arc from high amperage if it pulled far enough out of the terminal to be fully-disconnected. Would the "brain" notice this, or is it a simple "dumb-logic" on-off circuit?
Wasn't this just like a year ago you put that pump down switch in because of a defrost issue on this one?
What’s the function of that switch buddy? Do the staff twist the dial, it pumps system down for that amount of time?
@@thanktheknife yup! system pumps down and doesn't run for the set amount of time
My master helper doesn't like to pump down 👎 qrc
Chris I looked at the big picture and i noticed something that I guess you must have missed : there's no hair on your face , mate !? 🤔
Bill's back on the scene and Chris cannot compete, a concession to reality.
hi everybody
A backpack sprayer that is battery powered is very handy.
If you are charging more money for overtime (after hours) service calls, why would you ever be upset about it?
Because sometimes you just wanna go home regardless of more money. But you don't because you want to do a good job.
@@somethingsomeonesaid6455 Then if it is 4:30 PM, don't take the call. Or, take the day off and only do the overtime (after hours) calls. There are a dozen ways to solve the perceived problem other getting upset and then complaining.
@@DomManInT1 lol you purist. Haven't you seen yet perfection is relative? Play it by ear sometimes.
@@DomManInT1 Enjoy your day sir.
@@somethingsomeonesaid6455 None of your replies answers my initial question. Your first reply, "Because sometimes you just wanna go home regardless of more money" implies what a person wants, not what a paying customer wants, is what is important. So, if you want to go home, just do it. Your ability to do a good job when it is not top priority or when you are tired is reduced. My first priority is making money. Regardless if I am doing a good job or not.
Wow, who did the wiring on that evaporator?? I was doing a better job by the time I was six...

👍🛠️🤳🇹🇷🍻
First like comment and view whoop whoop lol
Stop being a cry baby 👶, doesn't look good to complain to do your job...
It's not strange to be frustrated when you're getting into the 60 hour weeks...
You’re clearly not a technician lmao, also boomer alert
@@FrostBlueFire Choose another profession if you can't handle it
@@timchester3010 ah yes the holier than thou! I bet you're one of the biggest whiners in your company, buddy. Im sure you have no problem crapping on other techs to get ahead? Just the vibes you give, your wife must love you.
@@FrostBlueFire Wife does love me married for 20 years..
