hey Chris ive been binge watching your videos i love the thought process and your way of making it make sense, ive learned more about HVACR in the past few weeks that i could have just picking it out of the internet. if i were a younger man i would have gone into this line of work it still interest me. doesn't hurt to learn new things even if im retired anyway thank you for sharing the information with us all

Another great video from HVACR VIDEOS. I've learned a lot about refrigeration from you. You feed the people what they crave......quality information and your big picture diagnosis. Keep it up Chris.
23:32 - Yeah, they're probably better off having a sub-panel branching from their main service, and have the sub-panel feed the refrigeration. It may not be necessary, but I'm a big believer in slightly-overdoing things; and it will open up a few spots on their main panel(s) for the future.
Tasty tidbit. To convert normal time to military time, add 12 if it is between 1pm and 11pm. If its midnight, it's all zeros. To convert military time to normal time, subtract 12 if there is no leading 0 (0100, 0700, etc). If there is a leading 0, remove the 0. Source: I work at a tv station. All we use is military time

Pull the blade off set it on flat ground and step on the middle of the hub to get the pitch down. I know it sounds kinda hackish but I have had to do this a few times. And it works pretty good no wobble in the blade and it's doesn't take much to get the amps down.
That intro. Lol! Of course they call you out on a weekend. People. Ugh. That beetle was just chilling. Hate when electronics fail. Always cool to see you repair these things though! Loving the videos!
I really enjoyed your first part, really good and your are the best. Always humble. that is why you are very successful and knowledgeable person. Thank you for your time and effort.
Great stuff. One thing though I don’t agree that cutting the line set and sliding insulation around the suction trap would be best. You’re better off mitering a p trap and using that. The fact that the trap had the insulation just slid around the trap is probably why it failed in the first place.
I have several locations RR that have those racks. One is completely disconnected, it only had compressor skids in it for all the production line and server line equipment that has long since been replaced with self contained units. One rack only has the cooler walk in left in it, same story for the rest except the freezer. Had problems with freezer and found it was still in there. Tomorrow replacing the external condenser for the bar units that died and using a unit sitting on roof left from a remodel that deleted what it was attached to. One rack only has walk ins and possibly one little unit on it. Long ago lost the ice machines in it and now they are separate remotes. One store has individual units with the condenser bypassed in them and piped over to a multi coil fan unit. That is a mess to work on. This store still has some units built into the server and main lines. Though walk ins are separate units. I do agree the filters are in a PITA location. Good luck on the complete change out. May I make a suggestion, gut the unit for the most part and keep the rack there and put the condensing units inside it with the main fans moving air through the whole unit and make use of the existing power distribution.
I love what you do, it help me with my daily task with checking storage Unit Composer and evaporator, but I hope seeing you working with Thermo King or Carrier. much love from KSA
Hi from New Zealand! That condenser coil is poked! Good product to use on your outdoor equipment is Corrosion X XD duty. Can go straight on circuit boards and all metal for awesome protection.
would it be 'more' correct to say the motor wasn't starting because of the bad cap, because it wasn't starting it would spin backwards because the other motor is running and pulling air past it instead of pulling air through the coil?
hey Chris. Don't know if you could see what we saw through the camera but the first new fan was a different height visually in the video vs the original that was running next to it. (taller= more pitch)
I've found using an actual shaft water slinger is better than those cheap ones that come on the new motors. The ones I use are plastic and they are around 3-4 inch in diameter. You could have raised the blade up on that shaft of the new motor to reduce the amps being drawn until you got the proper sized blade. Remember the blade is what determines HP and volume of air. Good job on getting them going!
If they don't have room in the Main Electrical Panel for all the new A/C units, what they can do is strip out the current Circuit feeding the Rack being replaced and use that Circuit slot to run a large Circuit up to the roof and feed a Sub Panel from it, then run all the new A/C Circuits to the Sub Panel...
I can never get over how the wiring is all just thrown in into these units. No double insulation, wiring channels or PVC conduit to protect them from rubbing on bare metal
If it takes more work, that means you need more current. Have you never stuck something behind a fan inlet? You'll hear the motor noise change as it tries to pull more air. Same for fan blade shape and pitch etc. That all changes the pressures needed to be overcome which will take more current.
I have some Ukrainian friends who now live in the US, they didn't believe me, Americans all over are very confused about times past 1200, for awhile they were trying to test people "I'll meet you at 1400", literally no one understood when they should meet. I won a nice bet with them.
I just use the 24hr clock by default. It's not exclusive to the military do I don't refer to regular 24 hr clock as military time. My girlfriend from Europe uses it but also uses our clock just as easily as I do. I can use Celsius a little easier than her for Fahrenheit. Shit all our units are mixed 😅 just like an American car manufacturer
So what ended up being the deal with only one fan cap? Did the working fan have it's own cap on it? I was also admiring the after-market wiring that had been done down around those interlock relays and the contactors. All the original wiring was neatly bundled and tied down, and there was this flying blue wire to the interlock relay, and a couple of flying red or pink wires up to the contactor. It made me wonder what that was all about, and why someone couldn't have run those wires neatly.
Thought the same, here in Germany you should make everything save so you can not touch live wires even when the top cover is off. Maybe some cover is missing?
Why is the P-trap in the freezer? To my mind any standing water caught in the P-trap would end up freezing and blocking flow and maybe cracking the pipe if it fills the pipe before freezing.
It’s a reverse trap in the suction line of the refrigeration tubing. It helps keep oil from getting stuck in the evaporator when the compressor is off since the compressor is above the evaporator.
On "making a mess" - would it perhaps be an idea to have a water catching floor cover when doing defrosts like this? Thinking along the lines of a towel with rubber studs to prevent it from being a slipping hazard...
Yes I found it, I will discuss this on my Livestream this evening 8/30/21 @ 5:PM on RUclips, come over and check it out. ruclips.net/video/ClYwq9ft2-w/видео.html
4PM, not sure why some people count up the from 12, there are different ways but mine is just take the PM time, add 2 on the last number, if 11, so its 21, just increase the first number by one and of course there is no 24 if you write it down, its 00 but most clocks show 24. Its odd writing it down as it seems long but it literally is not something you need to count around the clock to get the right answer and you are only 2 away from the time you need.
Yes, very different to Australia also. 240 volts probably makes a difference. In Oz this freezer would have a digital thermostat controlling the defrost, comp and fans. I never fit liquid line solenoids as pump down controls because the blowers defrost quicker and better with gas in them. And the LP remains as a safety rather than operating control. I haven't fitted one of those old Penn or any other analogue t/stat for 20 yrs
Hey Chris, I have a question; What is the best way for customers to clean and maintain the evaporator in walk in cooler/freezer. In my case took all the chunks off with soft nylon brush, is soap and water okay to break up the gunk on it. or should we save it for the PM at start of the year. Thanks for the videos, you do a great job explaining the what and why, in your videos. It helps a simple line cook like me take care of the basics and cut down on some of our headaches.
Agreed I need a proper vacation for sure!! I will discuss this on my Livestream this evening 8/30/21 @ 5:PM on RUclips, come over and check it out. ruclips.net/video/ClYwq9ft2-w/видео.html
1:45 I wonder why mechanical timers are still a thing. An RTC with a set of CR2032 cells as backup would keep time perfectly for 3 times the life of the unit, not to mention mains frequency synchronization. It's not like they're using the mechanical timers for switching anymore - it's all JUST through relays! A $20 microprocessor-based timer would last 30 years. Throw in a solid state relay and it would outlive you. I've seen
The scruffy beard intro was funny AF. Ladies and gentlemen, the HVAC Hobo!
This intro was the best. “Audio sync” lmao. Made my day thanks Chris.
It is a best practice to sync the audio with a clapping hand. That will be used for editing the video. 😃

would it be 'more' correct to say the motor wasn't starting because of the bad cap, because it wasn't starting it would spin backwards because the other motor is running and pulling air past it instead of pulling air through the coil?
You make me want to get back in the business!
Changing the pitch on the blades will move less air through then the original blade… that’s not a problem?
“Some dodo head” 🤣
I like your content. I have too much advise for one comment. But on after market motors always go 1/4 hp higher om trane and carrier.
As an electrical engineer, I am not knowledgeable about HVAC but I totally enjoy watching your videos for the troubleshooting satisfaction.
Felt the same about defrosting. Professional defroster and high price cleaning specialist.
Miss the noise though.

Yep, wouldn't see rubbish like that in Australia. Almost everything is imported here but the regulations and standards are higher
in the next installation try out the Daikin zeas inverter condensing units
Getting sloppy Chris 🤣
Pshhh I've been sloppy for a long time......
Nice video! Amazing how such a slight pitch change could suck 2 additional amps.

The defrost clock - DST - Daylight Savings Time - one hour
11:10 Military time? The reset of the world calls this time.
I have some Ukrainian friends who now live in the US, they didn't believe me, Americans all over are very confused about times past 1200, for awhile they were trying to test people "I'll meet you at 1400", literally no one understood when they should meet. I won a nice bet with them.

Many people use 12hrs time notation in China too, I don't think even the PLA is using exclusively 24hrs notation.
In Germany we use both, my friend will tell me to meet at five o'clock, but if it's something official like the office will close at 17 o'clock
So what ended up being the deal with only one fan cap? Did the working fan have it's own cap on it?

Military time just add 2.. so if its 4pm then add 2 which makes it 6 which is 16:00... if its 2pm add 2 which will make it 4 so it will be 14:00...
So if you add 2 to 8pm you get...?

It's 24 hours. Not that hard. Count 0/240000 to 235959
Better yet, just add 12.

I can’t believe how different your controls are in America from what we have in the uk.
Yes, very different to Australia also. 240 volts probably makes a difference. In Oz this freezer would have a digital thermostat controlling the defrost, comp and fans.
