"I know a lot of people say I use too much solder but I just like to be sure! It's my company I don't care if I use it and I don't care if my employees use a little too much solder, better than not using enough!" That's how to create a trustworthy company! Do the job right or don't do it at all!
I don't do HVAC for a living, but I do feel if you go a little crazy on the solder, it might be kind of unsightly, but it gives the joint more physical strength, which might matter if you have something like an out of balance fan that's vibrating the joint for years. I've certainly seen this in electronics.
Ha. I had an employee that constantly plugged up cap tubes and service valves doing just that. I do agree a little extra won't hurt but in his case it did.
Too many people use the ' I do it right because I do it twice' mentality when it comes to work anymore. I would rather use a little extra solder and not have to worry about going back in to fix a leak after you get the unit up and running!!!
I remember decommissioning mom and pop grocery stores because of the phases out of R-502 and R-12. I seen many owners crying because they could not afford the refrigerant retrofit. I just hope we don't just help the big companies and have some grace for the small independent owners. But I'm not very hopeful. Awesome video!!
I really love these longer videos where we get to go on the journey with you from finding the problem all the way to fixing it. In this case we even got to watch you replace the equipment. I thought it was a great video!
I do commercial HVAC service and on a lot of equipment they require the risers to decrease in size for proper velocity/oil return. You have to be very careful. I know most installers don’t take time to read the install manual” but they provide that information for a reason.
Yeah, I' 've had these issues with the same problem... The kitchen crew keeps going into the walk-in freezer leaving the door open or not fully shutting the door , etc. -- I serviced the hotel every week if not every other day. I kept my morale up by saying to myself job security, and that kept me humble elaxed. I appreciate the POV and Keep up the great work.
At 33:51 - some installers stop there and you can tell that the solder didn't flow as you would think, so when he says "use more solder" and double check everything, he is NOT kidding.....solder is cheap compared to "callouts" on a system you JUST fixed.....great vid - thanks!!!
Great video. Much different video than you normally put out there. Its nice to see another angle of the trade that most of us don't know or have tons of experience with. While i am familiar with load calcs for comfort cooling. I have zero experience with sizing refrigeration equipment and what goes into sizing it and all your components correctly. As usual......top quality information and work. Thanks for what you do for the trade Chris.
An objective definition of a "perfect" install is one where the customer is happy, the company is happy and the system performs as or better than designed. Everyone has an opinion about what they would've done. It's irrelevant outside of suggestions you may or may not want to use later. Your install there looks better than 95% of what I see in Houston and I'd bet solid money it certainly performs better. Great work!
After watching your video I understood its end of an era for older smaller sized condenser equipment. Whatsoever, loved your installation of new equipment.
Hi Chris thank you for another great video keep safe dude plus I hope you get some rest bite away from this condenser now hopefully you have fixed it nice one 👍
Wow - I can see why you like that Russel equipment - the way the wiring was routed inside, zip tied and done with care - what a difference from a lot of the other units you work on. Even though it's taller, won't that single thickness condenser theoretically be easier to clean? Also you think Russel went to single width because of that extra loop at the bottom from the receiver?
Those ecm dual speed motors were terrible a couple of years ago. I had a couple of freezers that chewed through the McMillan motors every 6 weeks. I couldn’t help but think about your drain line in relation to the freeze ups. Here in the mid south we have to install traps on the drains and smoke test them to be sure they aren’t drawing outside air. Very clean install.I like the fact that you used all components that can be locally sourced or likely have on your truck. The cover on the line set looked great. It looked as if your insulation had a woven exterior?

No reply required - one thing you might look into is one of the two part PE (urethane) expanding foams, rather than using the "good stuff" canned foams. It's often a bit better at handling temperature and humidity extremes. It may be too difficult to deal with for the small areas upon which you're working, but I thought I'd toss it out.
I only use Trenton here in Clearwater Florida. Already pre assembled with everything and it has the 2 speed “smart tech” motors, honestly haven’t had any issues with it.
I do the same Chris I use a little more brazing rod the guys that use just enough run risk of getting a leak at some point, also sick video!! Show em how it’s done!
What no Trane manual with long forms and graphs, lol. Great introduction into a few of the things to consider when sizing equipment. Also gives techs a better understanding of things to consider on hard to diagnose jobs. Great job.
Great video. I have always wondered how they pick equipment. I wish you had showed about wiring the relay for those fan motors. I know most of you guys know but I'm still in the process of getting comfortable with electric and retro wiring. As always still a great lesson. You dont know how many teachers and supervisors refer new techs to you videos because they help everyone get to where they want to be.

One way to get your customers to stop causing frivolous defrost calls is to simply tell them that after call number 3 that's caused by your people propping the doors open, I'll start charging you an Irritation Tax (AKA Asshole Tax) of $50.00 for the first call after the warning and increasing by $50.00 for each additional frivolous call after that ($100.00 for call 2, $150.00 for call 3 etc.)... Wanna bet you never get another call caused by the cooks propping the doors open? Heck, I'd bet you'd be able to hear the Manager scream at the staff from 5 Counties away...
Dont be so hard with yourself on installs you mainly seen to do is service . Those" instagram people " do installs all year arround so thats why it might look better. Stick with what your good at!
28:50 there is no such thing as too much solder. and you have to cool it, it softens the copper and prevents cracks and holes over time. pro tip: please ditch the wire nuts, use wago 221. wire nuts are borderline illegal in europe already. wago is also a lot cleaner and better over time by not twisting and mangling the wires making repairs in the future a lot simper and faster. never forget: the next guy is probably you.
American electrical standards and general practices are just shit in general. They clearly prefer cheap and easy over safety and durability. Not just wire nuts but other stuff I frequently see on this channel like those terminal boards, flexible metal conduit, disconnects with non insulated contacts, leaving wires dangling and zip tying them together instead of running them through tubes and trays where they can't rub out etc...
I disagree. When used properly, wire nuts provide a much more secure connection with less resistance. Wago style connectors are not nearly as secure and therefore create the chance of increasing resistance and heat. They may be fine fire low voltage and low current applications like led lighting, but should not be used on anything heavy duty. Just as an aside, it makes no difference what Europe does. They use the metric system and traffic circles smh lol
@@89dhvac wago's are actually more secure over time (they dont loosen up giving dodgy connections) and dont care about the wire type and can handle overload situations equally well or better. when dealing with ld and corroded wire it will hold up much better then wire nuts. this has been tested time and time again. your point of view seems to be more about personal opinion than fact based. And "when used properly" is exactly the problem. Nobody does use them as they should.
@@SupremeRuleroftheWorld I use Wagos alot especially on communicating systems and low voltage, however wire nuts still have their place and purpose. Find me a Wago that will work on 6g wire. By far the best connection/connector for larger gauge in my opinion is a Polaris connector but wire nuts (when properly used) will work just as well as a Wago. If you're putting Wagos on corroded wire, I don't think you should be giving advice about anything electrical.
@@laskahvac666 i am not saying you can put wagos or any connector on corroded wires, its just that they deal a lot better with corrosion (due to time, elements, heat) then wire nuts do. and unlike wire nuts they are insensitive to viberation from machines. and its not personal opinon, it is fact. and the 221 does not go to 6awg, it peaks at 10. beyond that you should not even consider 221's, wire nuts or whatever, the only thing solid enough (especially outdoors) is bolted terminal blocks and crimped connectors. you show me a wire nut that has been used on a 6awg wire and been on a roof for 5 years in the desert and i will show you a wire nut that has been utterly destroyed from the resistive heat it generated. for proper high current connections you always use proper sized crimped and heat shrinked connectors. if you are making more reasonable sized connections that are sensitive to the elements like sensor wires you use a wago gelbox for example.
This was really informative! Having a run-through like this would have been invaluable in my commercial/refrigeration classes.

28:53 Yup, $1 worth of solder is cheaper than trying to find that pinhole leak that you missed initially, or coming back a week later on an emergency call after that joint that looked fine fails in the middle of the night.
Had same issues with restaurants in downtown Cleveland. Walk in freezer packed all the way from the evaporator to the door and the only time they would call is towards the end of the day when they were closing. " Frustrating "

Yr old vid and my apologies for the late watch/ reply. With that said how about those wooden 4" by 4"s that weren't somehow fastened in place? You had mentioned tweakers earlier so I go immediately to thinking they can kick them out from under the skid.
You briefly mentioned in this video about clogged screens causing oil to be trapped inside the suction line accumulators. I haven’t been able to find any information about that anywhere. Can you explain how that works? What’s actually happening in the system to cause this? Still learning by the seat of my pants. I’m working on a walk-in right now that had an unexpected spewing of oil out of the low side valve on its condensing unit when releasing nitrogen after a pressure test.
1.love the music while you're soldering. 2. Love it when you talk about dealing with customers and your frustrations. It's good to hear stories from other guys on this topic. 3.love how you focus on quality and the big picture. The consummate professional. Keep up the good work.

you may want to steer towards R-449 .....it's a few bucks cheaper per llb. just a thought. both 448/449 are viable refrigerant solutions for the incumbent 404 /low temp apps. A lower GWP @ -51 boiling point could save you a few bucks on Retro's ! great video btw!
im honestly surprised HVACR equipment doesn't have more computer control in it, transport refrigeration is only controlled by computers, it can control discharge pressure by reducing suction pressure with electronic valve
The small restaurants won't have these. They need simple and cheap controls. You getinto larger commercial refrigeration and HVAC and they are all computer controlled.
I love it when he is like this equipment is in bad shape. I have a walk-in cooler that is 38 years old...and it has the original evaporator and when I bring up the wall caving in no one is interested in replacing it. One day it will collapse on an employee and I doubt we would replace it even then.
Great video again waited for it to come up even if I have to calculate the time because mine is CEST. I like to watch RUclips more than other streaming platforms and stuff because you can watch tons of stuff you like to see.
ECM motors are a huge mistake, the cost of replacement far overshadows any savings they might produce. Also failure rate is much higher than PSC motors. These green people making these types of decisions usually don't know crap about HVAC. Also a 12 gage wire should only have about 70% of full load. you have 21 amps on a 20 amp wire, not good. Even 10 gage is running it close to the 70% rating, but it is o.k.
Kinda a touchy subject ehh ? Depending on power cost and sizing, industrial motors can consume their own cost in power in months. Simple 1/4 kW induction motor from china may only be 100 quid or less but assuming some cycling it will use maybe 3kWH a day. In some countries that can be 90 cents !!!! if you can install a drive system that saves 1/3 and lasts a couple years....you get the idea. And electronics that fail in less than 5 years to a decade are not the fault of "electronics" but of idiot decisions by engineers and managers who make and sell em....
@@Zonkotron We had some 100 hp pumps at work and the drives for them are independent from the motors, and worked good. The fractional H.P. motors are not worth the extremely high replacement cost of them, lots of failures from bad power, lightening, and capacitor failures in the motors themselves. Thanks
@@Zonkotron Indeed. Those ECM Motors are not generally bad. It seems it mostly gets crappy as soon as someone tries to compensate for the additional cost there is. And from some IT related systems, I know those motors running at adapted speeds make a huge difference in cost savings, especially if electricity is a serious cost factor. I even have an ECM motor in my Grundfoss circulation pump that is built into my furnace as by energy conservation requirements. (Here in Germany Air Ducts for heating are quite rare, we mostly use furnaces for hydronic heating, even more so than air conditioning which already is rare by itself). That thing is working its way throughout the years for eleven years now without any issues. But for sure, the engineering behind it has to be solid. Also to get a bit picky here, I never heard anyone of those just blabbering about "Those ECM motors are bad/ a mistake / crap whatever it is" come up with any other good ideas on conserving energy. And with Chris being in California, I think they are in an area that knows possible blackouts during a heat wave as the supply cannot catch up with the power demand mainly from all the air conditioning I think he already showed how much the line voltage dropped in some areas in such times on several occasions. And if you add up the power savings from all those systems, that does not make the issues with the infrastructure / power grid any better, but at least it can take quite some load out of an already overloaded system.
Don’t kill telling the customers with a really, really need to know the time here. Remember stupid is as stupid does. And on the ones that you have to keep going back to keep charging them a premium price for your service. Maybe they’ll learn.
22:37 - Where can I find a list of typical TD values for different equipment (e.g., walk-in vs. reach-in vs. top mount fridge vs. RTU)? They all seem to be different. Is there a way know what the designed temperature difference is for a specific application?
@@HVACRVIDEOS Thanks for pointing me to the stream. Also, thank you for enabling the transcript so I was able to go directly to your answer by searching (49:45 - 51:17). I appreciate the invitation to email you later about the impetus behind the question. I _will_ go back and watch the rest of the recorded stream after I get home today.
Pssh, always going to be someone in the comments who tries to backseat tech. Like you said, your company, you drive. A little more solder might save you time and trouble of a visit to find a leak in the future. Love the bit with the lizard!
Hey Chris, I’ve never seen any of your customers (your videos) having an air curtain in the walk ins. I know the cooks hate these but when one of my customers continually leaves the door open, I install the curtain. Just curious your thoughts?

As long as you allow for capillary action to actually seal the joint it doesn't matter if you bead extra on the outside seam.

I see tubers that get it to start flowing then they get scared and take the heat away to early. (They worry about the names of the tips they use 😅)
Thanks for the video!

I will discuss the on my livestream this evening 9/13/21 @ 5:PM (pacific) on RUclips , come over and check it out ruclips.net/video/jyfQ49s2Lm8/видео.html
Thats a perfect install keep it up chris!! 🤙
Yr old vid and my apologies for the late watch/ reply. With that said how about those wooden 4" by 4"s that weren't somehow fastened in place? You had mentioned tweakers earlier so I go immediately to thinking they can kick them out from under the skid.
You briefly mentioned in this video about clogged screens causing oil to be trapped inside the suction line accumulators. I haven’t been able to find any information about that anywhere. Can you explain how that works? What’s actually happening in the system to cause this? Still learning by the seat of my pants. I’m working on a walk-in right now that had an unexpected spewing of oil out of the low side valve on its condensing unit when releasing nitrogen after a pressure test.
1.love the music while you're soldering.
2. Love it when you talk about dealing with customers and your frustrations. It's good to hear stories from other guys on this topic.
3.love how you focus on quality and the big picture. The consummate professional. Keep up the good work.

The lizard is going to be famous 😂
you may want to steer towards R-449 .....it's a few bucks cheaper per llb. just a thought. both 448/449 are viable refrigerant solutions for the incumbent 404 /low temp apps. A lower GWP @ -51 boiling point could save you a few bucks on Retro's ! great video btw!
Could you do a van and tool bag tour with all your tools and equipment??
You are busy now because you and your employees do high quality work and that is hard to find today with all the hacks out there!
What is the best way to defrost that ice cube you had going on there? What did you use hot water? Or a heat gun?
Sporlan rocks with the tech stuff / great to back you up with ..
im honestly surprised HVACR equipment doesn't have more computer control in it, transport refrigeration is only controlled by computers, it can control discharge pressure by reducing suction pressure with electronic valve
The small restaurants won't have these. They need simple and cheap controls. You getinto larger commercial refrigeration and HVAC and they are all computer controlled.
Flat roof penetrations you should use a Chem Link E curb. I've used them for conduit penetrations for pvc and they don't leak if you do them right.
Thx for sharing
Thanks for this type of video i loved learning how to size this stuff!
Watching while drinking my coffee before I install a mini split. Still dark on the west coast.
Professional job as usual , very neat looking ... Thx for the vid ...
That lizard wanted to tell you about Geico insurance 😆😄😁🤣😂😅
I love it when he is like this equipment is in bad shape. I have a walk-in cooler that is 38 years old...and it has the original evaporator and when I bring up the wall caving in no one is interested in replacing it. One day it will collapse on an employee and I doubt we would replace it even then.
Great video again waited for it to come up even if I have to calculate the time because mine is CEST.
I like to watch RUclips more than other streaming platforms and stuff because you can watch tons of stuff you like to see.
Hey Chris, watch that first step... it's a doozy!
You can order replacement outside trim from everidge(ics).
hopefully you kept the line-set from touching the galvanized steel, because electrolysis is nasty between the two metals :)
That's a serious sized receiver, I know nothing about hvacr but that seems massive
Good job man krep the video coming
what do you use to defrost the evap? hot water and a hose?? i assume the viper venom sprayer that's in your description?
This one’s for the books Chris
As long as you're charging them no problem going on a service call
My second visit would have been, you are getting a new grasslin defrost timer weather you like it or not.
I hate these kind of calls.
loved the vid,what was the pressure on that by pass valve on the condenser ?
Cool video!
That is a to of refrigerant in the new one. How much was removed from the old system as a comparison?
So if I needed to add refrigerant to the unit, I would need to back seat the service valve, correct?
ECM motors are a huge mistake, the cost of replacement far overshadows any savings they might produce. Also failure rate is much higher than PSC motors. These green people making these types of decisions usually don't know crap about HVAC. Also a 12 gage wire should only have about 70% of full load. you have 21 amps on a 20 amp wire, not good. Even 10 gage is running it close to the 70% rating, but it is o.k.
Kinda a touchy subject ehh ? Depending on power cost and sizing, industrial motors can consume their own cost in power in months. Simple 1/4 kW induction motor from china may only be 100 quid or less but assuming some cycling it will use maybe 3kWH a day. In some countries that can be 90 cents !!!! if you can install a drive system that saves 1/3 and lasts a couple years....you get the idea. And electronics that fail in less than 5 years to a decade are not the fault of "electronics" but of idiot decisions by engineers and managers who make and sell em....
@@Zonkotron We had some 100 hp pumps at work and the drives for them are independent from the motors, and worked good. The fractional H.P. motors are not worth the extremely high replacement cost of them, lots of failures from bad power, lightening, and capacitor failures in the motors themselves. Thanks
@@Zonkotron Indeed. Those ECM Motors are not generally bad. It seems it mostly gets crappy as soon as someone tries to compensate for the additional cost there is.
And from some IT related systems, I know those motors running at adapted speeds make a huge difference in cost savings, especially if electricity is a serious cost factor. I even have an ECM motor in my Grundfoss circulation pump that is built into my furnace as by energy conservation requirements. (Here in Germany Air Ducts for heating are quite rare, we mostly use furnaces for hydronic heating, even more so than air conditioning which already is rare by itself). That thing is working its way throughout the years for eleven years now without any issues. But for sure, the engineering behind it has to be solid.
Also to get a bit picky here, I never heard anyone of those just blabbering about "Those ECM motors are bad/ a mistake / crap whatever it is" come up with any other good ideas on conserving energy.
And with Chris being in California, I think they are in an area that knows possible blackouts during a heat wave as the supply cannot catch up with the power demand mainly from all the air conditioning I think he already showed how much the line voltage dropped in some areas in such times on several occasions. And if you add up the power savings from all those systems, that does not make the issues with the infrastructure / power grid any better, but at least it can take quite some load out of an already overloaded system.
Don’t kill telling the customers with a really, really need to know the time here. Remember stupid is as stupid does. And on the ones that you have to keep going back to keep charging them a premium price for your service. Maybe they’ll learn.
22:37 - Where can I find a list of typical TD values for different equipment (e.g., walk-in vs. reach-in vs. top mount fridge vs. RTU)? They all seem to be different. Is there a way know what the designed temperature difference is for a specific application?
I will discuss this on my Livestream this evening 5/20/24 @ 5:PM (pacific) on RUclips come on over and check it out ruclips.net/user/liveVU06CNEhVbA
@@HVACRVIDEOS Thanks for pointing me to the stream. Also, thank you for enabling the transcript so I was able to go directly to your answer by searching (49:45 - 51:17). I appreciate the invitation to email you later about the impetus behind the question. I _will_ go back and watch the rest of the recorded stream after I get home today.
that a dragon lizards
normal find them in hotter area
i have ton of gecko in my area lol
you are right about kindness it mean a lot to anyone
could you install a switch on the door with a 5-minute timer that would automatically cut off the breaker if the door was open longer than 5 minutes?
Pssh, always going to be someone in the comments who tries to backseat tech. Like you said, your company, you drive. A little more solder might save you time and trouble of a visit to find a leak in the future. Love the bit with the lizard!
What gauge set are you using? I want to get a set like that
Nice video
Hey Chris, I’ve never seen any of your customers (your videos) having an air curtain in the walk ins. I know the cooks hate these but when one of my customers continually leaves the door open, I install the curtain. Just curious your thoughts?
