It’s cool to see a professional at work who knows what their doing.

Thank you! I love teaching this trade!
Great install.....RUN THE CROSSBAR
The part I wanted to see was how the hell you got that new evaporator in the box in 1 piece. Haha. Also, since Alaska and California have earthquakes in common, definitely add that crossbar. I forsee that condenser on the ground after a decent shake.
That, and if someone bumps into the assembly with a tray cart, bends it and makes it drop the condenser... I wouldn't want to be the one who has to take the fall.
I thought about that additional crossbar when you showed your rough-in phase of the unistrut stand in the early part of this video, so when you mentioned going back to add it, I was like, "Yeah, I was thinking the same thing." Also, I see you decided to stay with the defrost timer after all. Lastly, any technician would appreciate not having to squat down or bend down to access the electrical panel. As usual, great craftsmanship!
I'm not an HVAC tech, but I watch your videos and commend you for all that you to do to teach people about the job. Be safe, and if you ever need a photographer, I volunteer for free to help.
Great video, Chris! I just recently changed out WIC and WIF condensing units. Both existing units were working and both boxes were full of product. Before I started, I said a little prayer that everything went smoothly and that nothing was defective with the new condensing units. I had someone help me remove the old equipment and set the new equipment, but after that, it was just me. The first unit I installed was the freezer unit because the freezer door is inside the WIC. Once I got the freezer running and down to temp, I could crack the freezer door to help keep the WIC at temp until that unit was installed and running. The prayer didn't work. The factory installed freezer low pressure control was defective. Without the control, there was no way for the unit to pump down and cycle off on temperature or for a defrost. I worked 10 hours straight with no breaks and I was exhausted. I wasn't going to pay a $100 opening charge hoping the parts house had the control in stock, so I had to go back to the job several times over the next 6 hours to manually cycle off the freezer condensing unit and put it in a defrost. At midnight, I shut down the freezer at -20 degrees figuring it would hold until morning. I got the control the next morning and installed it. Now, I'm waiting on RDI to reimburse me for my labor and the cost of the control. I'm not holding my breath, though.

Hell, all I know about HVACs is how to change the filters but I sure enjoy watching these videos. New subscriber.
I appreciate that you marked all the information inside the condenser box that you probably wish was there in other ones you get called to work on. If it's you the next time, it'll more than make up for the time it took to do and if it's somebody else, maybe they will learn something and start doing the same. As far as adding the extra cross bar, nobody ever had to apologize for making something like that too strong.
This is now one of my favorite tutorials from you for two reasons.
Data data data and documentation, maybe meaningless now but might help diagnosing something later for a baseline... Then "don't give people something to talk bad about you you later" because they do and will to make themselves look better to the customer. Both are simple things to improve your reputation and branding.
I really enjoy watching a professional who knows what he or she is doing. Thanks for making these videos. I also like the idea you put all the startup info on the panels. I used to do this all the time when I was servicing. I'm retired now but still enjoy the field of HVAC/R.
When I first started watching, I just skipped the ending break down. Now getting more into HVACR I really appreciate the endings. Thank you for informing us all in what you do on a daily basis.
I will be adding liquid level lines from now on, on the receiver on new installs. Great idea!
Nice job on the stand, makes everything easier to work on in the future
My goal in life is to be this organized in life.
Years ago I forced myself into using a 5 gallon bucket boss organizer with a cushioned seat lid from academy sports. It is the perfect height to sit and work on most RTU’s. Plus it works as a stepping stool in a pinch.

Nice install sir! Clean and hit all the points, hard to find techs that do ALL the right steps. Been to too many poor installs and having to fix it. Been watching you the past few years, keep it up!
Sometimes you just have to know when to make a stand.. lol
That is true and funny at the same time
Excellent work as usual. Definitely appreciate the attention to details and for the next tech Yes get the bar . In fact maybe even adding more to be safe.
All your videos and teaching are very appreciate it,very much, thank you very much and God bless you and family,with all respect, God bless
Nice setup, extra crossbar, yes. Filming employees, that’s where the stupid stuff goes on, pure entertainment and you can hold it up and laugh
Thanks for the video Chris. I really enjoy your videos. I love to learn new things and im always trying to improve my knowledge and skills. 21 years in this trade and there is still so much to learn still. I dont do much refrigeration anymore, but i still want to know about it and learn whats new. We have some accounts that we handle their refrigeration as well as all their commercial/ industrial equipment. Nowadays i pretty much am only commercial/ industrial. I love working on boilers, chillers, towers, pumps, etc. #hvac4life
Always enjoy the startup videos! Keep up the great content.
Excellent work and thanks for the awesome content stay safe and take care
Good stuff seeing the whole process!
Great work
Have a good day man
Nice install like you say always do the best so the other guy doesn’t talk crap keep it up thanks
Chris, thanks for the great video !
Great install. 👍🏾
Great videos Brother!
Absolutely great mate! I have 7 evaporators on a multipack and am looking to change them to splits…. This was exactly what I needed to see. Maybe you could do a controls step by step guide as well?
Good video! Another thorough job.
Thanks for a great Video.. good install..
Really, very good explanation and clean job. Thank you
Yeah that's the thing about subcontractors at my job they don't care about servicing what they install because they leave it to us afterwards. And almost every install that they do its not even service able. I hope that every subcontractor that does shit installation job has to break there backs for being idiots and not thinking about the next guy. Great job Chris!
Very very informational video. I am a student in an HVAC-R class and this was very helpful.
Nice instal Sir. Better than a lot of other stuff i ´ ve seen before 👍❄️
Great work chrissss!!!!
Great work and work ethic!
If I were at that restaurant I would have pushed you hard to put the new unit on top of the others. I really like space efficiency. That concrete pad would have been a pain though.
Thats neat, its interesting to watch how its done.
Another great video !!! If you are thinking about putting another support in for that frame, do it !!! It is better to overkill certain things and it gives you peace of mind. You did a fantastic job explaining why you are doing everything, where to face unit, to building a frame for unit etc. As you said you are trying to make a tutorial with these videos and your are doing a great job in my opinion. How your subassemblies of certain equipment before your final assembly on site shows the methodology you use on every job that I have seen in your videos. As for leaving notes, always when you do something funky or not really the norm that happens at work. When I worked in streetcars and we cranked off the brakes so we could couple up and push in the disable streetcar. I would leave a note that only the open side disc brakes are cranked on all others are off. I would also leave the crank off tool on the drivers seat so the person on another shift will question about the brakes being on or off and be forced to ask about it and look at the ticket. Keep the videos coming, I am addicted !! Thanks again.
Great to see installations that get service techs off their knees!
You have quality presentation which I have passed onto our apprentices down under.
Excellent video and job 👍👍👍
Great job and video like always
You are the best 👌
Nice repair Chris ...Good vid ...
Love to see it mate
Thinking a like true service guy when doing construction. Thinking about the next time when we have to service it and is it accessible 🙌
That corn on the cobs looks kind of off.
Good job very thorough 👍🏼
Thank you for the videos.
I was wondering could you look at doing a maintenance oriented video. How to check belts and tensions, greasing motors and bearings properly.
great videos 🤩
So sick, uni strut is awesome for this kinda stuff
Congratulations Beautiful install, i wish you were in NJ. You really know your sh**t
Very nice work
Nice 👍🏻 job.
Still using 404a in Philly. Thanks 4 vid.
Same here in Buffalo. I keep 22, 410,134,404 on my van
Very good job bro 👌👌👍👍👍
Great installation! Looks good! Like the stand! Great to be able to work on it standing up! One concern did changing the txv void any warrantys? Awesome to see you and Dad working together! Thanks for another good video!
Great in stall
LOL. At about 10:35, while discussing the wet rag compound, he points out the red/white tub being used to prop the piping up.
If you look at it, you will see a blue item (solenoid magnet?) attached to the shiny part (the solenoid?), with some wet rag compound on top. Stare at it for a minute or so...
It looks like he made a play dough gilligan, wearing a blue shirt & his ubiquitous white hat. There is a tube attached to the piping, that looks like a hand, and it appears as though "gilligan" is positioned in such a way that it looks like he is holding and peering through a telescope (seaglass?) at something behind & to the left of the camera (from our perspective).
Nice. A for effort, even if unintentional.
4:00 If you do build a stand to lift the new unit above the other unit, the hot air from the new unit won't drop into the other unit since hot air rises but if you're really worried about it, why not build a deflection plate angled 45 degrees up to catch the exiting air and deflect it up.
That was what I was thinking, it may rise but the suction of the other unit might force the flow down. I agree that deflection plate would bee a bullet proof solution.
triangles are a stronger shape than squares when building support systems. Very cool to see a professional install!
Really tidy mate 👍🏻👍🏻👍🏻
Good job my friend i always watch your video
When it comes to support and crossmembers, it's better to err on the side of excess. Maybe you don't need it, but do you want to take that chance?
You're right in your outro when you mention making the install serviceable. Even if you never have to worry about the next guy criticizing your work, you'll thank yourself if you come back for PM/repairs down the road.
Nice video
. . outstanding sir
As a 6 footer...i do 90% of installs on stands. Mounted properly it makes service calls a snap.
Nice job
La verdad tus videos son de los mejores.. 🤘🤘
I would think that raising the equipment would make it easier to work on too for future service.
Yea, I Like the idea of Raising the Units up to at Least Sitting on chair 🪑 Height. It would be nice to change out a compressor once while sitting in a chair & not on top of a ladder or on my knees.
Units raised up stay Cleaner too !
I will discuss this on I’m going live on CZcams this evening 12/14/20 @ 5:PM (pacific time) to talk about my videos and answer questions from comments, emails and the live-chat, Come check it out czcams.com/video/238PSHS5MIY/video.html
great job..
Great video.Could U pls give us a video exclusive on selecting a TXV whenever U Have the time,just in case u need to change the TXV to suit a particular refrigerant.
Excellent!!

To the end, please go back and put the support, that way you can sleep well 👍✅
Here in Tampa's county (hurricane state) all condenser units on roofs must be placed up on stands at least two feet up, usually aluminum I beams (3") with 2" round legs. Ron W4BIN
What grind my gears? Why run head masters? We did that back in the 80's and 90's in Sweden. The condensing units I have installed in cold north Sweden for the last 10 years hasn't been equipped with that, my colleauges can't even remember when they installed a unit with that kinda "feature". Not even with long lineset. Instead we run with fan cycling pressure control, either variable or on/off. And.. In the summer it can be about 30°c/90°f, during winter as coldest -30°c/-22°f, ok. It may take one or two startup tries before it kicking in sharp by those low ambients. Have never been a issue. We are just clearing the sight glass and keeping the level low as possible with enviroment in mind.

Great video 🎊🙏👏👏👏👏👏👏🌺💐🌹👏👏🎊🙏
My eyes hurt after seeing that liquid line cross over like that 😖
Curious why you didn't braze in the valve while the cartridge and the head was out? love the videos
nice job
This would have been a breeze with zoom lock. Over the last 2 years I’ve become a believer. I got a gig installing VRV system in a hospital for their 5 IDF rooms and I could not pull a fire permit since the hospital was still open (Texas is a bitch ) and I did it with zoom lock and pro press and I got down to 300 microns quicker than I’d ever done before. Also held 500 psig over 24 hrs! Not cheap though. But think about over 300 ft of line sets, 5 air handlers !! How many brazes that would have been
@hvacr videos run another cross bar like you said restaurant workers get mad when they get fired.
I did an install similar to this with me and one other guy and it took 6 hours
Of all the screwed up installations you have come across now is your chance to take your Vengance! Put the line set out in the walk way so they can smash it once a month! Hahaha 😂😄
Freezer start up and wire up
Is it me, or do the factory braise joints on the evap assembly look like they were done by a blind apprentice?
I Was thinking 🤔 the exact same thing when I saw that New evap ! Factory Welding Looked Terrible !!!!
@@OcRefrig
The piping also looked.... slightly crunchy. Like flux got on the pipes and wasn't cleaned off. Not terrible if it's a year old, but new I'd expect it green crunchyness free.
Quality control is almost non existent these days!! I will discuss this on I’m going live on CZcams this evening 12/14/20 @ 5:PM (pacific time) to talk about my videos and answer questions from comments, emails and the live-chat, Come check it out czcams.com/video/238PSHS5MIY/video.html
Just done one where I had to stack the units, no other space to put it.
I have a Job with two units stacked. I Don’t Mind Working on the top one , the one under it is interesting to work on. Two heatcraft units just like these in this vid.
@@OcRefrig i'm sure u did..... u never do installs i only see minor service calls...
Hey, my brain works that way too!
I get that you don't want to show your employees on camera. Couldn't you just pixellate/blur their faces in editing? That being I have learned so much watching your videos! I passed the Light Commercial Ready to work test at the start of my Commercial HVACR class thanks to you. I also love your work ethic! Do the job well and take care of the customer and your company. That's how it's supposed to be done!
KE2 makes an temperature controller paired with an EEV (a few different capacities) and 2 temperature sensors for the evaporator coil differential. I believe it serves the same purpose as that sporlan txv kit, make any valve you need in the field. I haven’t used one yet, was wondering if you have, or have thoughts and opinions about it.
Also you should add a couple supports because if they are like other will store crap under their too so hate to say it block them out with supports
Beautiful install!! Ya know Chris I can't type out in words to express how great your work is :)
Just remember the department of health is your best friend in refrigeration!
404a is outlawed in California? I wondered why you always seemed to use 448a
GWP for R-404A: 3,922
GWP for R-448A: 1,273
448A is the new gas that has been used to retrofit the racks at the stores that have HP80 in them.
R22 is being retrofitted to 407A And the A/C racks are now being converted to 407C.
It’s all being changed and then in a couple years they want to do it again.
Its funny most of the little things you describe about yourself as being "crazy" i also agree with and or already do too lol
Maybe a 48 inch high pressure treated plywood partition wall between the two units, with a simple unit-strut frame?
I would worry about possible condenser discharge air re-circulation using a partition wall. I'm not sure there would be enough clearance space taking that course of action.
Tyrone Sheppard ...a plywood partition would end up being higher then the unit is now, that would intend to prevent re-circulation
@@rmhanseniii i'm speaking of the discharge air from the new condensing unit hitting the partition wall you noted and then deflecting backwards toward the unit it came from, interfering with the dissipation of the heat from that condenser coil and causing high head. I did not mean the discharge air going from the new condensing unit over to the other condensing unit.
Great video and great work, does the heat block really protect the txv for damaging?
"We're brazing with nitrogen, so..." OK, so... what's the rest of what you were saying?
