THE WALK IN COOLER WAS WARM BUT NOW IT'S COLD

This was a call for a walk in cooler that was too warm but when I arrived it was cold and down to temp, I found the main problem but also found several other things along the way.

I guess your popularity and revenue has gotten to you. You're more long winded than before and I swear if i hear "big picture" one more time my liver will fail from taking shots with every mention. We get it. Look at the system as a whole not just component level. We get it, there's a bunch of things you'd like to do on the customers dime to satisfy your OCD and we also get customers don't give a crap. Your commentary has gotten stale but at least you can plug your sponsors and merchandise. Sucks that you sold out. Oh well c'est la vie

Love your honest no BS approach to things. I'd like to say i am the same way. Look at everything, give options, be honest. It leads to happy customers, builds trust with the client and leads to more work. Plus you can't make everyone happy at all times....but you can try.

[@HappilyHomicidalHooligan]

And it does sometimes lead to high-value sales because the customer knows if you're telling them they need this super expensive wizmo, they DO need it...

[@AgustinCesar]

Just one constructive critique: you could have clean the dirt out of where the compressors are. I mean, Just hose down slowly to the drilled holes so it looks clean and it does not become dust when it dries and gets caught up again in the coil.

[@Android_Warrior]

@@CRSolarice : He did mention the shop vac and that he will not go down and get it.

[@throttlebottle5906]

that stuff is usually caked up thick and stiff anyway, once wetted or high humidity/dew it's more or less permanent there, unless disturbed by brushing. so it's really not that big a deal. yes it would look good/fancy for the camera and I could see if there was just a major sand storm that deposited it. as for ash from the fires, that's like a hard blanket once moistened/wetted and i wont go anywhere either.

I’ve tried small shop ticket holders for note holders, but some guys take them. 😂 A label printer is great and a gold paint marker (writes on lights & darks). I have tried toe tags and then used packing tape over them so they wouldN’T wear out.

[@jeremyhall7951]

Hey Chris! How's it going? I may be the only person but I love being out in a storm. I dont mind the chaos. I also don't know how many Mini splits you install but There is always 2 terminal locations with those captive screws on them that don't get used. I collect these religiously and keep them in one of my parts bins. I hate not having a wire landed especially on fuse or overloads.

[@tracysellman1562]

HVACR Videos, Chris I hear what you are saying, as a 30+ year Master HVACR tech in the heart of the old west Tucson, Arizona. I have learned and was thought to not only be a problem solver for all my customers be it commercial or residential but to always get them involved in the decisions to solve the problems. Also when explaining it to the customer don't talk down to them. But dumb it down to layman's level and not use industry-standard terms. Let them be a part of the desition making process. I always told the customer "If it was me or in my professional opinion I would recommend this" No one wants to hear "it's F*cked" or "it's a POS" without a solution even if that is a total replacement of the equipment with an explanation as to why. Good Job!

[@nikolas8845]

Dang, I live in Oregon where I work in the rain pretty much every day from September to May... It didn't even occur to me until now that most people aren't used to the rain lol. I don't even notice the rain. I just don't know how you guys deal with working on a 130-degree roof in the summer.

[@throttlebottle5906]

only rain? now factor in the snow, ice and frigid cold or just ask Texas al about that. then again ask any human/state/area/country that's claiming oh it's an out of ordinary hundred+ year storm, which caused major issues, deaths and more, which they claim should have never happened. clearly they didn't pay attention to real science, nature's signs and were too busy pocket padding.

[@ivangoubarevpascual4301]

Rain might not be that big of a deal depending on what equipment you have. What is scary though is having lightning while being on a roof.

[@HappilyHomicidalHooligan]

@@ivangoubarevpascual4301 Especially while standing next to/touching METAL EQUIPMENT CABINETS... Grounded Equipment Cabinets AKA Potential Lightning Rods... Granted, the chances of that particular cabinet getting hit is very, very low since there is a LOT of nearby objects that are taller, thus better Lightning Rods (in theory), but the chances are not 0%... NEVER work outside when Lightning strikes are happening less than 10 Miles from your location if you can at all avoid it...Lightning has been PROVEN to hit up to 10 MILES away from it's point of origin in the clouds...

[@ReliableHVACR]

Yeah always good practice to chit chat a little bit and just ask how everything is, look around a little. You'll be surprised, you'll get an extra call here and there.

[@tallbrian100]

Yes its easy to get slid on operation logic, I assume solenoid valves are power close but I have run into a few that are power open, some what uncommon. When you hotwired the valve I was thinking ? but I have not worked on defrost timers. An NC valve is normally only used when fail closed is needed for safety, for a cooler fail open is better.

[@williamcolon1898]

Do you happen to have a part number for the wand? Great video

[@Seb22601]

22:40 I'm pretty sure that says tS and not t5, the S and the 5 just look the same on a 7-segment display.

[@FishFind3000]

If you need good radar data look up the app radarscope. It gives you raw radar data from the NWS.

[@terryj.macmullen9968]

when the condenser starts getting dirty some service guys start making adjustments to gets results.works for a while but state of condenser continues to gets more clogged.so now it comes to a point where where the condenser has to be cleaned.a lot times after cleaning the unit regains the lost capacity but the controls are not readjusted.now things freeze up.

[@kiap9188]

I have been doing this for 5 years and never come across an open solenoid being used for refrigeration! Time clock wired in series with Temp Control and Temp Control energizes the Normally closed solenoid on a temperature rise [Solenoid opens then pressure control starts the compressor] ... Can't picture how a N.O. solenoid would work!!! I always use [N.O. solenoids / valves + actuators] for heating applications "When thermostat satisfied then solenoid closes"!

[@mikee8737]

Beginning of the video you mentioned this unit having 2 evaporator coils. Is there a difference between a 2 coil and single coil evaporator in terms of servicing? Also, are there any benefits for a unit to have 2 liquid line solenoids? Thank you for providing excellent HVAC content for us!

[@BeezyKing99]

[@Sixta16]

Design of these units, where wiring lies in the water, bare wires hanging in the weather... this would be like illegal construction in EU.

[@deineroehre]

All these open terminals are a huge NoGo for every Cabinet build in the last 20 years, except in the USA seemingly. And this design flaw were the water from cleaning or storms has no way to get out of the unit is so silly, what would be the problem to have a slightly falling slope and a drainhole at one end of these units. Is sensible mechanical construction/engineering something which doesn't exist in the USA? It wouldn't cost anything to mount the bottom a slight slope (except the compressors, the whole mechanical part could be mounted on a risen platform to let the water flow away from electrical/machanical parts) and drill a hole, but you could clean the inside with lots of water with no problem and no hazard.

[@The98deville]

Dude idk if its just the video but at 1:03 you see the trap on the evaporators and they look like they arent done properly. The outlet looks like its higher than the inlet of the trap. Maybe its just the video but damn it looks close.

[@williammeszko3299]

Theoretical Question: Why control head pressure by flooding the condenser when you could accomplish the same thing by turning off the condenser fan? Seems a lot less risky, and cheaper too. Thanks

[@CRSolarice]

Just curious and I apologize if this is a dumb question: Is it possible to contaminate your leak detector by actually allowing the tip to come in contact with a leak source? For some reason I reallly like the idea of that device, it must be a real time saver in certain situations.

[@HVACRVIDEOS]

I will discuss this on my Livestream tonight 3/15/21 @ 5:PM (pacific) On KZbin come check it out kzbin.info/www/bejne/qIuQpHedg9CfnKs

[@throttlebottle5906]

good question and the answer is yes for most every single detector made. the oil in the gas can contaminate them, as well as water/moisture off the outside of the lines. some are far more sensitive than others, depending on build and actual sensor location (heated type with sensor at the tip are far more critical to contamination) I'm sure he'll explain it far better and simpler than me.

[@Lissica1]

Is the Stratus detector better than the D-Tek?

[@nessnesu6202]

For SYSTEM A or SYSTEM D breaker around 18:50, isn't the wires going into it considered to be illegal, double tapped? Considered an issue cause one wire could come loose.

[@colinstu]

Those breakers (square d QO, or whatever the commercial version is) are rated for double taps. As long as both wires are the same AWG anyways.

[@kevinpoore5626]

You get hazard pay for working in those type conditions don't you and I'd recommend keeping a hard hat in the truck for the situations like that hail hurts lightning kills LOL keep on keeping on
