THE WALK IN FREEZER KEEPS FREEZING UP

[@thomasschulze6715]

"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!

[@etherealrose2139]

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.

[@greendryerlint]

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.

[@Happyoldfashionfamily]

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.

[@greendryerlint]

Yeah, maybe don't go THAT crazy with the solder..

[@75LS1Vega]

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!!

[@KentuckyReef]

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.

[@meeder78]

Nice install! Interesting to see the whole sizing process. And not to forget, I love the 80's inspired synthpop music :-)

[@lqueryvg666]

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!!!

[@winstonwright3613]

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?

After watching your video I understood its end of an era for older smaller sized condenser equipment. Whatsoever, loved your installation of new equipment.

[@jasonjohnsonHVAC]

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.

[@falloutguy8878]

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 👍

[@DocNo27]

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?

[@Thermoelectric7]

Single row might help keep the head pressure lower as well, as it all gets nice cool ambient air.

[@robertlowrey5485]

[@fatsuperman5556]

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!

[@aswiendharmawan4869]

Hi, always wait for your amazing videos, watching from Indonesia... 🙏🏻

[@tbelding]

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.

[@sherwinalvarez7365]

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.

Good morning! thanks for the vid

[@thesilentonevictor]

Great information Chris 👍

[@SupremeRuleroftheWorld]

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.

[@arnobruynen6073]

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...

[@89dhvac]

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

[@SupremeRuleroftheWorld]

@@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.

[@laskahvac666]

@@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.

[@SupremeRuleroftheWorld]

@@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.

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.)...
