I think your hitting the nail Chris , We always have to make the balance between perfect and functional. Now with the covid ... it is a whole new game . I have many customers who have cut labor loads down dramatically. Forklifts are sitting idle and pm service is not being done. Fast forward a few months and they find the industrial battery is dead , now it is up to us to see how we can help the customers... Basic point is , I make money from them making money , if they can't make their money , they sure as S don't want to pay me .. if I take it like a wild man , they never call us back .. fine line , customer relations are huge . Be safe brother !
Kudos for this video. It proves I'm NOT the only one biting my tongue about customers' zero maintenance (my former boss once tried to calm me down by stating, "George, I once flew to SINGAPORE and all I did there was change his filters; that was an19 hr flight OUT, 19 hr flight BACK ,and ONE hour on site").
This video would be perfect to show to people who are saying "we dont need preventative maintanence, it will be OK" to show why proper maintanence of air-conditioning is important.
I peeled off half an inch of dog hair from an evaporator coil a few times . I cant believe some people would still like to have the old furnaces to move air into their homes.!!!
I pulled a bag out of an A coil that was part of construction some 10 years prior. The bag was used to block dirt from going down into duct boot during taping n sanding. They were never satisfied by other co. Everything pointed to not enough air flow but fan ok,duct size ok. Used a camera to see if evap was clogged but to my surprise wala ther3 it was,a bag inside the coil covering bout 75% of the flow through the coil. Quick fix,removed it and the unit work 100% afterwards....
Brings back memories of my 38 years in the field!. Now a HVAC Instructor, I definitely like the video, will use it for why we have preventative maintenance to avoid what you ran into ran into Chris, but this will never go away many companies or businesses just try to get filter slamming cheap maintenance plans and think this crap will not happen.
Another great video. As an electrician, I just hooked up the electrical and never thought that maintenance was needed. My thinking was that you set an ac and just let it run for five or ten years and then replaced it. I learned differently. You have great videos and an honest disposition. Great job!!!
I worked with a lot of guys thinking they are above cleaning units it's the other guys problem when I would bark at them and say cleaning is a repair it fell on deaf ears. Love your attitude towards these units as if they were your own kind of had the same mentality taking pride of what you do.
These videos really help me look at a bigger picture every time I step up to a system. I've only been in this trade a couple of years and I watch these like they're homework, but the good kind. Thanks.
Just a note of encouragement to you, I'm head of maintenance for two restaurants and you have no idea how nice it is to have contractors that are open and transparent about the work that needs to be done to the equipment. Even if it means I have to turn you down for a smaller job that I can do, that transparency is what's going to keep me coming back to guys like you for the bigger stuff. Keep up the good work and thanks for sharing the stuff that you find in the field!!!
Man you are the epitome of pride and quality. Anyone who employs your services should be honored to get such great work. Your OCD as you often say will do right by you and your customers. If nothing else, when you look at it you can be proud regardless of what others think.
Great job. Just came across this video. I was an instructor for HVACR you do a great job showing reality of the trade and you seem to be a true professional. Keep the information flowing, we need your videos to show how it should be done.
I’m a medium/heavy duty truck tech and marine Diesel engine tech... and I literally wait for new videos to be posted. I’ve learned a lot from watching these videos and even applied some to fire truck and ambulance hvac systems!
The various refer units on the ferries I have work on over the years, the bulk of the work has been cleaning. After finding your videos I'm realizing even more how important it is. Great videos, great work!
HVAC control wiring is a nightmare. Why isn’t everything ran nicely in wire duct or something? Us electricians would be fired for doing work like that in our control panels.
Nice looking tie-wrapped wiring results in service people cutting to gain access !!! Hot wires hanging Not Touching other wires is actually better than wires all bundled together !!!!!!!!! That's my theory and I sticking with-it
Chris, Just wanted to let you know I love your videos. I used to work on rtu's at a large corporation. I took classes and learned mostly on my own. I wish I had your videos then. I have learned so much. I was noted as one of the guys to go look at the units when there was a problem with any unit. I could normally get it running, if not I had a couple of pros that would always help me. Never went beyond my level. I did however learn to keep those units clean. Makes a huge difference. Those units are not 16yoa and still running. Thank you for your videos.
really shows the quality of the food in a place how they care about their equipment, everything there is greasy and they are too cheap to maintain it speaks volumes about the work ethic of the business owners
Truth is today I find most managers rely completely on your expertise and watchful eye to tell them what’s going on. if you don’t theyThey don’t know, some job walks I’ve done, the engineers walk me to the roof and say I’m not Allowed to go up there per company policy.
@@adambergmann7716 haha, I worked at an anchor store in a mall before where this was the case. I literally got paid to chill on the roof with our HVAC guy and learn some stuff while I was at it. I definitely want to get into the trade but I know I need to lose like 90 lbs before I can comfortably work in these conditions.
I just left two little 5 ton ‘14 models.... both dirty both belts beyond replacing... filters looked like a sleeping bag... I did just what you did cleaned them fixed one refrigerant leak. All that for a fraction of what two other shops wanted to charge customers for two new units.. lol... people are something else. Great work bubby keep up the honest trustworthy ethics that everyone watching your videos should practice
I’ve worked on some Carrier RTUs just like this at a couple Popeye’s locations. Cheapest RTU possible and used as a MUA for their kitchens. Duct is nasty, coils are filthy within a week of cleaning. Compressors short to ground every couple years because they run them in winter with no safeties, no Crankcase heaters, no economizers. I write up the issues and concerns and make recommendations, get the pricing, they never approve. Then it breaks again and they dump money down the drain not wanting to fix it right.
You gotta make a plot out for them of how their long-term profitability will be better if they let you 'do it right' so they will be paying you for cheaper PM instead of having to completely replace.
@@Patriot1776 Exactly, show them the cost per year of fixing a crappy system vs. the cost of replacing the entire system with a better design and much lower per-year maintenance costs... Wanna bet the new system gets paid for completely before the end of the 3rd or 4th year?
Only took me 6 months of restaurant refrigeration work to get there. There's a certain sandwich chain I wouldn't eat at if I was starving to death and they were the only place with food for miles.
I like how you prioritize the tasks that are essential vs the ones that are more optimum. It is clear that failing to have work done is only kicking the ball down the street, there's no real economy, usually with additional costs.
With all that damage and with the age, they should really replace the unit(s)...I had to replace mine and now my wife likes me again. Thank for posting this..learning much.
Hi Chris, It cleaned up well enough under the circumstances, a lack of maintenance is often easier to deal with than badly done maintenance. I think back on times when I should just have refused to work on package units because they were scrap as a result of how they had been treated. Best regards, Duncan
Oh, as a side comment, on a three phase motor, you can just switch any two phases, if it is running backward. I saw you were using phase tape to keep it right, but it is faster and easier to replace phase tape than replace the whole thing. Just a thought.
6 more screws and you would've had the filter rack out of your way! Just bustin' your chops. You do great work and I truly appreciate your videos. Too bad I"m in KS and you're in CA. We'd be a great team.
I know it’s a pain in the butt, but I only take readings with both circuits running. ( you already know that) If they had pleated filters in the ceiling, rather than unit, duct work and inside unit would be far cleaner. I’d be concerned about customer bankruptcies these days. You are one hell of a salesman. Great job, great video.
As the owner of a mega warehouse and office complex I'm always thinking partnership with the HVAC firms...We do 4X a year PM and it's the only way to keep things functioning and extend the capital equipment life...Excellent video and wonderful channel.
I kept looking at that rip in the side panel. I was going to say that you could probably find a sheet metal shop down the street that could have welded or braised that back up. But then I realized that you have a torch and silver solder, and *you* could braise it back up if you wanted to. It wouldn't be a new panel, but it would keep the weather out of the electrics. Silver solder would be a bit costly, but still cheaper than the time to take it down the street.
Most businesses don't do preventive maintenance to begin with. Its crazy how bad they let things run until it's just beyond repair. This unit was close it looked like. Good job man.
WEG is a Brazilian Brand of eletric motors and transformers and it's the most famous brand in the world, and the best ones too! I user WEG motos all my life and they are insane.
13:43 I been watching from the beginning. Call me crazy and may sound like its stupid. But during the time stamp i put on this comment, If you have a pack full of washers and maybe some longer screws. You can raise the fan motors up another half inch, and could make all the difference in the world with how its flowing the air past the condenser and up out the top. because the fan motors are hanging from the spider web and facing down. If you raise the assembly air has less of a gap to pass and cycle back around inside the case and around the compressors.
Man i never thought that watching some dude fixing up ac's would be so interesting, I'm 16 thinking about what to do in my life but currently I'm thinking about ether being a mechanic or maybe fix ac's
Broken, I'm 61 years young and I've been in the A/C and refrigeration industry since 1976. It has taken care of my family and me well. I've worked both sides of the counter, parts& equipment sales and the service side. We need new techs in this industry so go for it. You will learn something new everyday as well learn people skills. Good luck my friend.
Kent Arnold would an A/C tech be something you’d need to go to a trade school for? Or do some companies do like an apprenticeship style of learning? I work in a warehouse as a forklift operator and the job just isn’t for me. Bouncing around on a lift for 12 hrs with little to no human interaction is a nightmare on the human psyche. You can only have so many conversations with a pallet of chips and cookies xD
I wish I knew a commercial A/C guy locally to get bad motors and blowers off of, I love rebuilding those things. Bearings are a super easy repair most of the time and it'll make the motor last many more years.
Wonder if you could put a small shroud around those refurbed fan motors, to channel the airflow out the unit better. Blades lower, hole lower, problem solved?
You truly went to down town with that rtu so good job....Lennox has AHs set up like that with the blower tension plate being a major problem cause it warps when added tension
Good video man! Just got done changing out carrier blower motor about 20 minutes ago in that same style unit! They had a universal blower motor on site to change it with. Pain in the ass wiring. You can wire it for low or high voltage. Obviously only high-voltage in this case. About 12 wires or so. Keep up the awesome videos!!
"Again." Seems like it's a thing. "Again......" Once you start you can't stop. "Again." But one thing I will say is that you're thorough and meticulous
Nice watching these videos, seeing someone from the same trade just different part of the industry. Very entertaining! Glad I don’t have to carry all of my tools up a ladder and through a hatch :).
For the record, I'm an electrician but enjoy your HVAC videos. I want to point out your commentary in regards to checking the phase rotation in the disconnect right before you went to startup the unit. Standard color code orientation for 208/120Y 3 phase systems is black, red, blue, left to right, top to bottom. If you are looking to reverse the rotation at the disconnect, you would simply swap a couple of the wires at the bottom of the disconnect. When you swapped both the top and bottom wires(line and load), you simply changed where they landed in the disconnect since the line wires at the top would still be connected to the same load wires at the bottom, just in different positions in the disconnect. It also reversed the standard blk, red, blue color code. There is no benefit in doing this.
I will be happy if someone tell me how we find out RIGHT PHASE just looking voltmeter. Because I don't know until starting compressor or blower motor. And Chris ; you have very good knowledge and work ethic.
You can't determine phase rotation with a normal voltmeter. His meter (a fieldpeice sc480) has a specific mode for measuring phase rotation. Presumably the meter uses an internal reference clock to carry-forward the waveform from the first measurement and hence compare the phase with the second measurement.
I see several stages of wear and tear in these videos: 6) I'm gonna recommend they get a new unit 5) Completely trashed 4) Nightmare 3) All jacked up 2) Catywampus 1) We just installed this new unit TODAY
Hey, have you considered doing a video about R-22? Over here in the UK, it has been illegal to repair/recharge systems with it since 2015 (even reclaimed R22) and now the US has banned manufacture/imports of it. It will only be a matter of time until you are in the same situation as us over here.
To add: Watts = Volts x Amps works for DC, but for AC that will give you apparent power. To get active/real power you need to also multiply by the power factor (On the replacement motor, it actually lists it at 0.80). For 3 phase, you also have to multiply by the square root of 3. Overall, Watts = A * V * PF * (1 or sqrt(3)). Then to make it more interesting, that's the real input power. You then have to multiply the result of that by the efficiency of the motor (0.869) to arrive at the nameplate rating of 2.2kW/3HP.
Woooowwwww!!!! Did you see the heat exchanger!?!?!? And restaurants don't ever do any PM work. Not until it's broke, which will be during the most busy part of the day with 100 clients inside!!!
Question???as a commercial tech, do u have sales numbers you have to meet? Do have up sale new systems, IAQ, AND REPAIRS? Joe crisara sale options? As a residential tech, when we do a maintenance, if there is nothing to sale, you get out of there quick, but make it look good.
No I do not have sales quotas I have to meet, I will discuss this on my livestream this evening 8/3/20 @ 5:PM (pacific time) on UA-cam come on over and check it out, if you can’t make It to the liveshow no worries as it will post as a normal video afterwards ua-cam.com/video/_-VEaqQzoKk/v-deo.html
How do you clean lent in the coils from a laundromat unit? Also from a residential unit with a clothes dryer vent at the condenser? Cleaner is not 100. Still restriction....
13:51 Is it possible to add some shrouds to the fans to compensate for the thicker motor stacks? That way, since the motors are too long to allow the blades to get up into the housing, you simply lower the housing around the blades... That would eliminate that aspect of the overall problems in a manner that should cost much less than replacing the motors with OEM motors...
Oh you are in cali. I worked in the central valley from Sacramento as far south as merced all the way east to hope valley and west to san fran bay area.
If the bean counters (upper management) saw a spreadsheet of a repair that could of been caught early. Then draw up a spreadsheet with a graph to show the differences in cost by doing planned maintenance and catching the repair early. They would be on board in a heartbeat, the problem today with upper management is that they are to lazy to see the value because it doesnt effect them today. Most upper management just like to put out fires and dont have the vision to see pass that. There is huge opportunity if you approach it right and get to thier boss. Pulling repair data for the last 12 months and setting a complete maintenance monthly budget which will include planned maintenance to further reduce cost and keep the customer for a lifetime because you just dont want to be a repair company. You want customers to see you as a partner and sometimes going that extra step is were succesful businesses shine.
If that is a ducted return what would be so best for those restaurants is return air filter grilles. And then you can put a 4-inch filter in in the grill. Honeywell makes high-efficiency 4-inch filters that are made for a return air filter grilles. That we keep the ducts and big chunk of the unit from getting gunked up. That would be ideal for those restaurants especially after a duct cleaning if they ever did that
Could you patch the issue with the condenser fans by creating a duct with some right-angle flashing to increase the airflow? I know it'd be make-shift, but when you're working with cost sensitive clients would it be better than not changing the condenser fan motors out?
its all about the $$ bucket.. tagging a PM to a repair is something we did many times when I was in the industry.. often a company would authorize a repair but couldnt get auth for a bare PM, but often maint personnel are ecstatic if you can "hide" a PM in a repair.. you cant fudge the papers but can say that all therse items were required to complete the repair so in essence you can bake a PM into it.. corp bean counters have no idea what all is required to make these machines work.. and also the ramifications of not making them work right.. spend a few hours now to clean a coil and have lower electric bills and happier employees / customers or not spend it and buy a couple compressors in august when its 110 out and 100 in the building!
I live in ladakh India and in winter the temperature drops to -30°C with almost 0% moisture in the air. Which vrf system do you suggest I should install?
Restaurant profit margin is somewhere between 3 and 6 percent per google .At 50 perfect capacity I'm sure they would love the best maintenance but they can't afford it .
Boy was that one greasy. Could you make some 1/2" spacers from small pipe and raise the fans so that they are in the cone more. Great video and many thanks.
how do you tell electrically which direction motor spins by reading meter? all I been exposed to, in meat dept, had open shaft, you saw which way motor turned, & if spun backwards, you switched wires either on plug, or outlet. good video!
His meter (fieldpeice SC480) has a special mode for it. You can't do it with a normal meter. Presumablly the meter uses an internal reference clock to extrapolate the waveform from the L1-L2 measurement and compare it's phase to the waveform from the L1-L3 measurement.
For future reference I run into the same situation with the wrong condensing fan motor was put in and it was too long this is a fix, albeit not a great one you stack up washers on the top of the condenser then put the whole fan guard on top of the stack of washers then put bolts through as long as the system is on a roof and no one can stick their fingers in the opening you should be okay.
I've been watching a bunch of videos. Why does most of this stuff happen? It seems like preventative maintenance just isn't done. Do most places just go with the philosphy it's cheaper to call you in once every so often than to have a worker actually change filters, and clean out equipment?
I think your hitting the nail Chris ,
We always have to make the balance between perfect and functional.
Now with the covid ... it is a whole new game .
I have many customers who have cut labor loads down dramatically. Forklifts are sitting idle and pm service is not being done.

That's because there are too many sheep out there giving into the democrat bullshit.
There is a way to fix the Venturi problem on the condenser fan motor add a piece of sheet metal about 3 inches or so to extend down do the blades.
Kudos for this video. It proves I'm NOT the only one biting my tongue about customers' zero maintenance (my former boss once tried to calm me down by stating, "George, I once flew to SINGAPORE and all I did there was change his filters; that was an19 hr flight OUT, 19 hr flight BACK ,and ONE hour on site").
Take the removal stem back out of the cormax tool body and crack the ball valve to release pressure and confirm cormax Schrader is sealed.
Can't clean it up too much. Some of that dirt might be structural!
Make sure you get some good OEM dirt from the manufacturer just in case.
This video would be perfect to show to people who are saying "we dont need preventative maintanence, it will be OK" to show why proper maintanence of air-conditioning is important.

I've worked both sides of the counter, parts& equipment sales and the service side. We need new techs in this industry so go for it. You will learn something new everyday as well learn people skills. Good luck my friend.
Kent Arnold would an A/C tech be something you’d need to go to a trade school for? Or do some companies do like an apprenticeship style of learning? I work in a warehouse as a forklift operator and the job just isn’t for me. Bouncing around on a lift for 12 hrs with little to no human interaction is a nightmare on the human psyche. You can only have so many conversations with a pallet of chips and cookies xD
As Steve L. would say: "Give her the old 'how ya doin', mama!' "
She's low on juice, gotta give her some more juice
I wish I knew a commercial A/C guy locally to get bad motors and blowers off of, I love rebuilding those things. Bearings are a super easy repair most of the time and it'll make the motor last many more years.
Great job Chris. That was a nasty unit!
2:20 Ha! "The Zip Tie Zipped To The Zip Tie" Hahaha!!!
It is extremely satisfying watching cleaning of an A/C unit :)
Wonder if you could put a small shroud around those refurbed fan motors, to channel the airflow out the unit better. Blades lower, hole lower, problem solved?
You truly went to down town with that rtu so good job....Lennox has AHs set up like that with the blower tension plate being a major problem cause it warps when added tension
This is so satisfying to watch.
Good video man! Just got done changing out carrier blower motor about 20 minutes ago in that same style unit! They had a universal blower motor on site to change it with. Pain in the ass wiring. You can wire it for low or high voltage. Obviously only high-voltage in this case. About 12 wires or so. Keep up the awesome videos!!
I wonder how much junk got blown out of those ducts after that blower wheel was cleaned😂
The blower wheel is really dirty and the ducts are sooo dirty also! Yuck!
Looked like the ducts were going for that 70s shag carpet on the walls look.
By the looks of that Ra drop I wonder how dirty the return grilles are? I'm sure all that gunk on the blower didn't help that motor.
Love your videos . They’re a great training tool. Nothing is half assed .
"Again." Seems like it's a thing. "Again......"
Once you start you can't stop. "Again."
But one thing I will say is that you're thorough and meticulous
Nice watching these videos, seeing someone from the same trade just different part of the industry. Very entertaining! Glad I don’t have to carry all of my tools up a ladder and through a hatch :).
For the record, I'm an electrician but enjoy your HVAC videos.
I want to point out your commentary in regards to checking the phase rotation in the disconnect right before you went to startup the unit. Standard color code orientation for 208/120Y 3 phase systems is black, red, blue, left to right, top to bottom. If you are looking to reverse the rotation at the disconnect, you would simply swap a couple of the wires at the bottom of the disconnect. When you swapped both the top and bottom wires(line and load), you simply changed where they landed in the disconnect since the line wires at the top would still be connected to the same load wires at the bottom, just in different positions in the disconnect. It also reversed the standard blk, red, blue color code. There is no benefit in doing this.
In this case given your knowledge and ethics the best you did was the best they would ever get. Good job! 👍
That blower looks like a new tool and I see you love using it. NICE!
I will be happy if someone tell me how we find out RIGHT PHASE just looking voltmeter. Because I don't know until starting compressor or blower motor.
And Chris ; you have very good knowledge and work ethic.
You can't determine phase rotation with a normal voltmeter. His meter (a fieldpeice sc480) has a specific mode for measuring phase rotation. Presumably the meter uses an internal reference clock to carry-forward the waveform from the first measurement and hence compare the phase with the second measurement.
pre video guess: there is a dead body blocking the duct jk. love the vids as always
kevin heaton the old tech fell in there and they took over because they couldnt find the other guy
@@jasonmurawski5877 wtf u talking about???
I sense a conspiracy
AC mafia wars
probably
lots of work! it looked really good!
Do the video when you are cleaning those dusty ducts.. THEN measure how much dust you've collected...
I see several stages of wear and tear in these videos: 6) I'm gonna recommend they get a new unit 5) Completely trashed 4) Nightmare 3) All jacked up 2) Catywampus 1) We just installed this new unit TODAY
In a pinch instead of using washer for shims you can use a old belt until you can make it right...
Great tip thanks!
Its satisfying to see condensers being clean
Hey, have you considered doing a video about R-22? Over here in the UK, it has been illegal to repair/recharge systems with it since 2015 (even reclaimed R22) and now the US has banned manufacture/imports of it. It will only be a matter of time until you are in the same situation as us over here.
Hey Chris, 1HP=746 watts. to get your watts, multiply amperage by voltage. I hope this comes in handy one day :)
To add: Watts = Volts x Amps works for DC, but for AC that will give you apparent power. To get active/real power you need to also multiply by the power factor (On the replacement motor, it actually lists it at 0.80). For 3 phase, you also have to multiply by the square root of 3. Overall, Watts = A * V * PF * (1 or sqrt(3)). Then to make it more interesting, that's the real input power. You then have to multiply the result of that by the efficiency of the motor (0.869) to arrive at the nameplate rating of 2.2kW/3HP.
Different motor manufacturers RATE their motor HP in different ways, so HP is a very imprecise number for rating motors.
Great video! Total makeover! 👍🏼
Wish I had the nice trouble meters and guages when I was doing hvacr. Good job I have seen worse
Woooowwwww!!!!
Did you see the heat exchanger!?!?!?
And restaurants don't ever do any PM work. Not until it's broke, which will be during the most busy part of the day with 100 clients inside!!!
Question???as a commercial tech, do u have sales numbers you have to meet? Do have up sale new systems, IAQ, AND REPAIRS? Joe crisara sale options? As a residential tech, when we do a maintenance, if there is nothing to sale, you get out of there quick, but make it look good.
No I do not have sales quotas I have to meet, I will discuss this on my livestream this evening 8/3/20 @ 5:PM (pacific time) on UA-cam come on over and check it out, if you can’t make It to the liveshow no worries as it will post as a normal video afterwards ua-cam.com/video/_-VEaqQzoKk/v-deo.html
First time I saw your video. Instantly subscribed. Amazing work. Learned a ton. Keep up the outstanding work!
Thanks bud
Wow, that thing was filthy. I doubt that blower was moving much air and the coils had to be split to clean them properly.
Excellent work and thanks for the awesome content and wow that blower is so dirty I am surprised it still works stay safe and take care
I have taken blowers to the local car wash to pressure clean them... LOL
Holy crap watching you clean that unit is my ASMR Hahahah love cleaning a dirty unit
How do you clean lent in the coils from a laundromat unit? Also from a residential unit with a clothes dryer vent at the condenser? Cleaner is not 100. Still restriction....
You should get one of those small portable electric power washers for cleaning parts that wouldn’t be damaged by it
Pulled my head back at 2:32 you got me 🙄😂
13:51 Is it possible to add some shrouds to the fans to compensate for the thicker motor stacks?
That way, since the motors are too long to allow the blades to get up into the housing, you simply lower the housing around the blades...
That would eliminate that aspect of the overall problems in a manner that should cost much less than replacing the motors with OEM motors...
That is one well used unit.
Oh you are in cali. I worked in the central valley from Sacramento as far south as merced all the way east to hope valley and west to san fran bay area.
10:29 is that a Steve Lav reference lol - Cattywampus
If the bean counters (upper management) saw a spreadsheet of a repair that could of been caught early. Then draw up a spreadsheet with a graph to show the differences in cost by doing planned maintenance and catching the repair early. They would be on board in a heartbeat, the problem today with upper management is that they are to lazy to see the value because it doesnt effect them today. Most upper management just like to put out fires and dont have the vision to see pass that.
There is huge opportunity if you approach it right and get to thier boss. Pulling repair data for the last 12 months and setting a complete maintenance monthly budget which will include planned maintenance to further reduce cost and keep the customer for a lifetime because you just dont want to be a repair company. You want customers to see you as a partner and sometimes going that extra step is were succesful businesses shine.
If that is a ducted return what would be so best for those restaurants is return air filter grilles. And then you can put a 4-inch filter in in the grill. Honeywell makes high-efficiency 4-inch filters that are made for a return air filter grilles. That we keep the ducts and big chunk of the unit from getting gunked up. That would be ideal for those restaurants especially after a duct cleaning if they ever did that
Could you patch the issue with the condenser fans by creating a duct with some right-angle flashing to increase the airflow? I know it'd be make-shift, but when you're working with cost sensitive clients would it be better than not changing the condenser fan motors out?
I didn't know you can check phase rotation with a meter. WOW!
What kind of meter do I need to look out for or feature?
The model number is printed on the meter, it's a Fieldpeice SC480.
its all about the $$ bucket.. tagging a PM to a repair is something we did many times when I was in the industry.. often a company would authorize a repair but couldnt get auth for a bare PM, but often maint personnel are ecstatic if you can "hide" a PM in a repair.. you cant fudge the papers but can say that all therse items were required to complete the repair so in essence you can bake a PM into it.. corp bean counters have no idea what all is required to make these machines work.. and also the ramifications of not making them work right.. spend a few hours now to clean a coil and have lower electric bills and happier employees / customers or not spend it and buy a couple compressors in august when its 110 out and 100 in the building!
I live in ladakh India and in winter the temperature drops to -30°C with almost 0% moisture in the air. Which vrf system do you suggest I should install?
Restaurant profit margin is somewhere between 3 and 6 percent per google .At 50 perfect capacity I'm sure they would love the best maintenance but they can't afford it .
Boy was that one greasy. Could you make some 1/2" spacers from small pipe and raise the fans so that they are in the cone more. Great video and many thanks.
how do you tell electrically which direction motor spins by reading meter? all I been exposed to, in meat dept, had open shaft, you saw which way motor turned, & if spun backwards, you switched wires either on plug, or outlet. good video!
Would be interesting to learn
His meter (fieldpeice SC480) has a special mode for it. You can't do it with a normal meter.
Presumablly the meter uses an internal reference clock to extrapolate the waveform from the L1-L2 measurement and compare it's phase to the waveform from the L1-L3 measurement.
Ive cleaned so many units just like that even worse over the years. Hell have you run across pigeons inside them?
The dead animals are always a fun surprise,
Never use oem so much money,
That motor pulley is wrong looks to big
@@keepthinking2666 Its probably adjustable.
@@keepthinking2666 only if customer wants it. I always gave them a choice depending on situation.
For future reference I run into the same situation with the wrong condensing fan motor was put in and it was too long this is a fix, albeit not a great one you stack up washers on the top of the condenser then put the whole fan guard on top of the stack of washers then put bolts through as long as the system is on a roof and no one can stick their fingers in the opening you should be okay.
I've been watching a bunch of videos. Why does most of this stuff happen? It seems like preventative maintenance just isn't done. Do most places just go with the philosphy it's cheaper to call you in once every so often than to have a worker actually change filters, and clean out equipment?
Another great video. Good info, even for an old air balancer.
