I think everyone in hvac should learn from this guy
I did. In 2019, I started watching this channel and in a year ended up in a van. I took my 608 Universal and worked all through COVID.
@SovereignTroll hell yea
Absolutely
I work on restaurant equipment primarily and I tell all of my fellow techs to watch him. The diagnosis mind he has is critical for our line of work.
I started learning when I was 12 from my dad who was in the trade I'm much older now and still keep up with the trade to help out friends, family and people I meet through family but I've taken a military route but still keep up in licences and usually get a mechanical licence in the current state I recide in just to A make extra ends meat and B to help families who don't have a lot of money to make sure there house isn't sweating or freezing there families
I've taken to doing that at work now when turning equipment on... "1..2..3 please don't blow up!"... the look on my project manager's face is priceless!
You and I both know that "temporary" fix will be quite permanent. The alternative is most likely shutting the restaurant down for a significant period of time while almost everything in the ceiling is rerouted, and that's not only costly, it's lost sales as well.
One month away from the two-year anniversary of me reporting a nonfunctional exhaust fan...
And the Baxter mini rack oven messed up so badly this past week. After a repair last Saturday, this Tuesday I was baking croissants at 130° instead of 325°. I texted the store's group chat with a demand that Bruce, the Franchise Owner himself, be immediately notified and address the ongoing oven repairs, or I would contact Dunkin' Donuts directly. Wednesday it was repaired again, and Thursday it was 238° instead of 325°.
The same week, our $15k a piece used McDonalds OG Frappe machine (Taylor Island Oasis) began on Monday with random blender motor activation when not in use. Tuesday, the keypad was replaced. Tuesday afternoon, the keypad/brain lost its calibration and would not blend after ice was crushed. Wednesday, the keypad was replaced again. Thursday, the keypad was falling off the machine (it's a dumb peel-and-stick membrane keypad with fragile ribbon cables, or as I like to call it, "a way to keep making the manufacturer money after the sale" 😆).
Our walk-in fridge pan drain line STILL goes uphill, it's not being fixed, the blame is "it's an old walk-in, it just needs to be replaced." Well, yeah, now that the floor is saturated, it DOES. Oh, and the walk-in freezer floor now has water intrusion from below, and the floor is getting lumpy as it's frozen now. Just effing great.
And our renovations? Pushed back again, no estimate on when it's going to happen.
Delfield sandwich station has 5 different slices in the line cord's insulation - at least the last time I was brave enough to pull it out from the wall. Conductors aren't damaged - yet - but I've ordered every single crew member to NOT move it and clean behind it until the cord gets replaced, it's been two and a half years since I noticed the first slice and reported it, and was told "it's not that bad right now." I don't want anyone to move the equipment, the back panel severs a conductor, and 🔌⚡🪦It's a pain to move because our expedite monitor stand is bad (and has been since at least 2012) and so the terminal sits on top of its printer, which sits on the top shelf of the Delfield.
Oh, there's the GFCI receptacle on the Drive Thru counter that hasn't worked since BEFORE my last time working there in 2012. The Test and Reset is stick in the middle, and it's been that way. That's what, a fifteen-minute repair if you go really slowly?
I swear, if there ever is a fire there, I have STORIES TO TELL. Like the ground pin from one donut case's lighting cord stuck in another receptacle, and I've banned anyone from using that lighting until the cord is properly replaced and the metal cabinet is grounded. Cord (missing its pin) is tightly wrapped and rubber-banded with a note on it inside the back cubby. Excuse me if I care about my crew's safety.
I just don't get it at all. Perhaps I never will. Sometimes you gotta spend money to make money, or spend money to at least keep making the money you're currently making. July 2023 was the most profitable month since the store opened in... Gosh, 2001? Maybe before that? And our store is often the highest-sales within the Franchise Owner's zone? Maybe put some money into the store that makes most of your money, and your crew will be happier, and customers will be happier, and your profits will grow even more? Hello? **tap tap** 🎤Is this thing on?
Delay timers should be mandatory for all air conditioning equipments to save the compressors
Agree, totally dumb the manufacturers can't spend an extra $10 on a little timer that will save thousands of dollars in repairs. I add them to all my equipment with pressure or temp switches if it doesn't already have one.
@@TechnicalLeeI just install one and add it to the bill. I like that tue manufacture leaves it to the technician to sell one to make more money.
@@TechnicalLee unfortunately they don't due what you just said right there it's about money but hey as much as HVAC companies make they could add it at the time of install just like cars and dealership added features
@@TechnicalLee You want to make less money?
I'm in HVAC school, starting my final quarter next week. Every single class, we watch one of your videos. I like how thorough
you are in your videos.
It may look bad, but the easiest solution likely will be to install rigid ductwork along the ceiling of the kitchen from the supply vents to the front area of the kitchen to direct most of the cold air right to the cooking area. Then the Manager can turn the thermostat in their office up to something approaching Sane without melting their cooks...
Sure, if the cooks look up they'll see the big silver tubes running across the ceiling, but it should be both functional and out of sight of the Customers and that's what truly matters here...comfortable cooks and happy Customers...happier Customers actually since once the cooks become more comfortable due to not cooking themselves, the quality of the food should go up...
You’re not understanding the importance of the return, he stated that in the beginning of the video, if you truly understand air conditioning/refrigeration, you would know it’s not about putting cold air into a space, it’s about removing the heat and that’s not too likely to happen if your only return is located in the office space which is always at lower temperatures than the kitchen and your thermostat is located in a hot spot, then your unit won’t stop running because it’ll keep trying to satisfy the set point.
If you use ductboard, you can build a wide, shallow duct across the ceiling. That minimizes the chance of banging into the duct, and you can usually paint it.
In the past worked on McDonalds stores maintenance had a unit similar to that. We just drilled a monster hole and reran duct work. It worked fine until they had their remodel three years later.
Your Customers are so Lucky to have your Experience Level Maintaining Equipment. It’s Safe to Say you’re a Strong Tech and Company Owner. Thanks! 👍🙏
2 🐦 with 1 stone...thank you for sharing with us.
Unfortunately when remodeling people dong look at the “big picture “ put in new stoves coolers etc. but don’t realize that thermal demands in the work spaces will need to be addressed as well.
Return air is the bane of my existence.
You did the best of the situation. Real, root solution is to get those returns in the correct places. I hope they don't use your temp hack as a solution
Awesome instead of waiting around for the thing to defrost you fixed the walk in. Saving your time and the customers money. fixing stuff when you're already there beats spending time driving back out
Nice job on that cooler condenser. I like that vs sweating in a new pressure switch and having to blow the charge. 👍🏻
I love how it's 90°F and you make no mention of the temperature 😅
When the Manager said "It's working, I don't want to make a Work Order for the Walk-In.", I'd have looked him in the eye and said "Do you want to spend a few dollars today fixing it now with no downtime, or spend a few hundred dollars for a late-night Emergency call when it fails when you need it the most? Right now it just needs a pressure control and time delay, later it will need a pressure control, time delay AND compressor..."
I suspect I'd have the Work Order a few minutes later...
😄😁😆😅😂🤣
Unfortunately, it depends how addional work orders verses service calls for broken equipment viewed by higher-ups
Wouldn’t it also be an option to close supply vents close to the return and maybe add some near the cooking appliances?
This way you would get more cold air to the cooks and proper air circulation
that could be a redneck fix if the existing duct is large enough. better that with making the existing supplies near the returns into more returns and add as many supplies in the hot area as possible. but I'm guessing the ductwork is at the limits as is.
Truly love the way you trouble shoot.wish I could work with U.
watching from Vancouver
Just ran in to this same issue. Glad to see my thought process of their issues validated with this video
What a cluster, hate coming in behind others to fix issues, never easy.
Could you get by short term with a carefully placed fan to blow the hot air towards the reruns or the cold air away? I’ve done that in computer data centers.
Cook will probably knock over or move the fan but maybe 😂
@@adamdnewman Not if it's a tabletop fan with the base screwed to the ceiling they won't...
@@HappilyHomicidalHooligan You underestimate the craziness in most kitchens, 😂
One or two industrial style wall-mounted fans, blowing towards the return.
Close off the supply ducts in the back and force all the supply to hot zone. As long as there is open space then the air will eventually get to the returns.
It’s nice seeing you posted after a long day of school. Keep up the good work 👍
Good job champ 👍🏽u a bad boy Chris Tnkiu for another great class amigo
if a 8 inch return duct is all you can fit to the back kitchen you can install a booster fan in it or to it to incress the cfm flow and wired to the evap fan
Looks Like 👍 Frosty the Snowman inside the Doors of the Outdoor Equipment. 🤔
Just dealt with a restaurant that had its bar return in the kitchen. 🤔 Started tripping the interlocked duct detector taking down all of the units. Owner was furious! It's hot and my customers are walking out the door! I don't want smoke detectors in my HVAC system. They don't care what needs to be just make it work. You have to somehow calm them down and direct them in the right direction.
Saw the preview on tictok. We see u over there. 😊
I'll hazard a guess that this will be a permanent temporary solution...
Nothing lasts longer than a temporary fix.😁
Great video. That freeze stat gave me some good ideas for a problem customer.
Let's hope it works... never had to do this before but theoretically it should work perfect
@@HVACRVIDEOS well I know they work for what they were designed for. I will let ya know
Thanks for sharing Chris. Next time, instead of interpreting the coil to the contractors, you can remove the brass jumpers on the LTB for comp 1 and 2. Does the same thing, and you don’t have to change wiring.
Nice little learning vid Chris ... Thx
Definitely make a video when you go to make a follow up on how you fix this.
Good job Chris, the delay timer or anti short cycle timer and freeze stats should buy them some more time.
What about creating an air transfer from the cooks line to where the returns are with an in duct fan to help pull the air over to the returns? Or turning the ceiling into a ceiling plenum?
I was thinking, why didn't he put delay timers on with added the freeze thermostats, because they'll probably end up banging on and off too much.
and later in video! you did. 🤣
21:43 No idea whether this is at all feasible... but is running a mini-split over the cooks line to take some of that load a possibility?
At worse, 2 mini-split. 1.5 (18000btu) tons each shall be enough.
just locate the returns and thermostat closer to cook line
I’d put those “temporary” freeze-stats on the common suction lines (2 comp system)… not on a specific coil leaving circuit, for a shotgun approach. I do understand that the real fix is to relocate the unit’s air returns though.
If the specific circuit is restricted/plugged, then you’ll cycle the unit comps unnecessarily
I call those snow men compressors.
Couldn't you cut back the air volume at the diffusers closet to the return grilles and push that supply air up towards the cooks line? Depending on how many and how big the supply diffusers are serving the cooks area is of course. You could also see what kind of horsepower there is left on the blower motor and maybe speed that sucker up along after adjusting the balance of the supply air diffusers. Might create some air noise but being that its a kitchen i doubt it would be that big of a deal. Also, verifying the minimum outdoor air volume the unit is capable of on a worst case scenario day and ensuring the min position is setup to bring as much outdoor air as the specs allow. I work as a commercial test and balance tech and supervisor in northern Michigan so i don't have much experience with the refrigerant side of things nor the climate that you work in. For me, that makes your channel that more interesting and informative to watch. Thank you for the no nonsense educational content!
Thanks a lot for this video I learned a lot😊
Awesome video
If anyone is really concerned about one plugged metering device tripping the freeze-stat you could always put two in parallel (fixed it) on two separate circuits. That way two would have to plug, or it really is freezing up. But that would eliminate one plugged circuit taking down the unit.
I believe you mean parallel them, so they'd both have to trip open at once to shut it down. 😉
@@throttlebottle5906 Correct, I was forgot they are closed and open when tripped. I was thinking they are open and close when tripped. They drop out, not pick up. Thanks for the correction!
i had the same problem at a restaurant and it had the remote sensor above the cookline with all the heat and return in the storage area. I moved the remote sensor to half way between and no more frost/freeze lockouts.
I work at a restaurant that has this EXACT SAME PROBLEM.
Outstanding video as always very much appreciated 👍
Cut a 20"+ hole in office door with a grate. Mostly block the A/C outlet in the office down to like 10%.
Your so good at explaining things brother, glad you are sharing your knowledge with us guys.
The Trane unit will lock out on high pressure when the freez stat opens. No time delays needed.
change the make up air too the hood to condition air from that unit . That would lower over all temp on the line also need to add a modulating outside air damper to allow more air in when the hood is on
Hey from Germany 😋
Good call adding the time delays. Did you write on the wiring diagram the changes that you made, for the next tech?
Ran into that a few times. I put in grates above the cook line, to allow the heat to rise into the attic space. Untill they approve the proper work for the returns. They will just leave it, trust me.
Some times is not a good idea to go OEM,some times is to go better.thanks for sharing.9:20 2 co and 30 ci
Sucks that these folks didn't bring you onboard to get your thoughts before their kitchen remodel. Could have saved them A LOT of heartache.
What about using the Attic area as a central return? Or can you blow out that wall where you shown where the return vents are that interlock with the fire suppression to shut in the event of a fire if you need that for code in the area
I don’t do much restaurant work but could you make it an open return and put egg crates in drop ceiling
Put a supply damper in the cold area to choke it down and more air for the kitchen 😉
Increase exhaust hoods and add more outside air to the system, it'll add to running cost, but just let the outside be the return?
Air to water unit with cold beams or cassettes by the cooks maybe?
Hi. Chris
Good. Stuff
Maybe the solution would be attic air return with perforated ceiling tiles may be feasible?
incredible it would frost up that bad!
Did you adjust the TXV on the freezer too?
It was clearly flooding back….
Multiple smaller parallel return ducts, either recombining for the actual returns or more smaller returns?
0:21 holy cow that compressor is literally iced up
John McClane would hate this attic crawl space
Without knowing the actual layout, could you turn a supply vent into a return in the ceiling?
can you come up with a new base lift for the ac unit up 2 foot sit on to add two new return in to hot side kitchen without modifed the ac look at it next time the freezer gose down
Can you run 100 percent outside air
Can you just remove the ducted return and install egg crate in place of drop ceiling panels where needed. Is that not acceptable in a kitchen?
What about using a small whole house fan to pump air from point A to point B?
Could you of done open return in drop ceiling with just grills and no flex.
Could you use a duct on the ceeling to bring the return from the kitchen? or a fan blowing from kitchen to return
Got enough ice?
ngl that ac became an Ice maker
Judging by the pressures, it kinda looks a slightly low on charge. You coulda probably gotten it too 33-34 degrees saturation to better avoid freezing temp.
The lower pressures were because of the low return air temps and an undersized return
Can’t you use a physchrometer or some type of cfm tool to check for proper cfms?
Just throw a defrost clock in there lol
Put a ductless mini split in that area.
We all know they will NEVER pony up the cash to redo the ducting..
Wouldn't it be easier to move the zone control sensor instead of the return vents?
Nevermind you answered it at the end lmao. Love the channel.
Move that unit over the kitchen and reduct install new small unit in place of original unit
Is that the same ac that was making the thumping noise a few videos back?
Would the system still function with the return near the supply blocked to force it to draw from the return closer to the line? I suppose you would have tried it already if it would have provided enough airflow… I’ve seen other commenters’ suggestions for egg crate over the line into the attic and then to open the return to the attic, but that’s not really ideal over a greasy line because any airborne grease that bypasses the exhaust hood would then make its way into the attic… (yuck!)
A 60-foot run, maybe a 1 or 2-inch duct tubing?
ALC controls?
Ice Ice baby
Sounds like they need a minisplit in the kitchen
It’s been almost a year. Has the customer done anything with the return air ?
Any more freeze ups?
I no longer service this customer, this is now someone else’s problem
This is a hair brained idea, but would a walk-in system work in that part of the kitchen? As a split system! Yes it'll need filters on it!
Took on some trane units?
the compressor on the right looks odd?
Looks very old and why the green color and not standard black?
That's a danfloss compressor generally supplied by trane HVAC.
Black are generally Copeland Emerson
Great job. You can't make diamond rings out of horse turds.
How can I be your apprentice? I live in Arcadia CA
Needs 7000 cfms less outside air.
Since this is a cook line this system should be using 100 % outside air or at least 50/50.
Damn.. it looks like a thick strofoam
👍🏿
FYI that trane unit is not field convertible for side discharge.
Return air.
Might be able to remove the economizer and run exposed ductwork on the back of the machine.
It seems you are holding the camera with one hand while doing all the work with your other hand. Why do you not buy a head mounter camera so you can use both hands? That would drive me crazy.
