Your son should be thankful to have someone teaching him the trade. Many people including myself are paying thousands of dollars trying to learn this trade. He has a great instructor. Thanks for the upload.
32 year HVAC commercial and residential tech , licensed for 25 years and I have to say you are awesome. You were honest, you looked into every possible scenario and beyond, plus you just knew what you were doing and that was obvious to any tech that has been in this field for some time. I am guessing, but that was probably your son or a family member filming you and that is also great.
You have a really great setup and I am very impressed with this video. It encourages me to keep doing a better job and stay honest and have integrity in my work. I get discouraged sometimes working in the HVAC industry cuz of what I see and hear and run into on jobs. That young man should be very thankful you are teaching him and showing him the correct way to operate and to trouble shoot the problems that we run into in the field.
Thanks again and God bless bro.
when should u check the evap or A coil for service or cleaning? i got this spray no rinse stuff for it but havent used it yet
@@fishman80 .... If you keep your filter clean and replace it about once a month regularly, your coil should stay clean for quite a few years. If you smoke indoors or have pets that shed or if your return filter box is on the floor instead of on the ceiling, then it will tend to get dirtier more quickly. All of this being said, I have not cleaned my evap coil in my house for over ten years because I make sure the filter never gets to dirty before replacing it. If you have a package system, you can open up the duct attached to the unit and the roof and inspect it to see if it needs a cleaning. If you have an attack unit you can do the same and if you have a closet unit, you can take the filter out of the box and shine a flashlight up at the coil and just stick your head in the plenum and take a look at it. That evap coil cleaning fluid you have is pretty good stuff and works great for just oxidation. If you have dirt and debri or pet hair on the surface of the coil, you should really rinse or even use a wire brush to brush the debri off after you spray the cleaner on it and have let it set for 15 minutes or so.
I hope that helps.
skyym3 that was a very detailed explanation and cant thank u enough. Really appreciate your time
@@fishman80 .... Awesome. God bless bro.
Yes -- isn't it great to have this start-to-finish on a service call. It puts it all into context. Thank you, T&N.
I'm in HVAC school right now. Thank you for posting this.
Getting into HVAC for the first time. I got the basics from Google (Terminology, parts & functions) & this was helpful in a day-to-day practical sense. Thanks, Sir.
A Regular No AC Service Call -
Contact someone. Call ahead? Obtain Key. Masks? Foot Slippers?
Check Thermostat. Powered? What do you hear?
Locate Circuit Breaker to AC Unit. Any Double-Poles to AC? Lables on poles? (hopefully?)
Breakers are sometimes outside with Meter to Electricity. Be sure the breaker is "off" and not "tripped". If it is tripped, do not turn it on until the compressor is tested for ground or there is a grounded voltage source somewhere or it could go Kaboom! LOL.
Flip to On. Listen. What do you hear?
TURN OFF CIRCUIT!! Remember to turn of Unit before removing parts for Troubleshooting.
-
If Fan does not run, either Fan or Running Capacitor. Check for Jams or Trash in the way of Fan. Check R-Capacitor. Likely R-Capacitor. (The Outside Unit will have 2 Capacitors (Batteries). Starting & Running Capacitors) What does R-Capacitor look like? Bulged up? Likely went Bad. Discharge R-Capacitor with Proper Procedure & Grounding. Do not create a bridge Arc & Zap yourself! Remove Part from Harness & Wires. Use Microwave Probe to test R-Capacitor. (Test Compressor?)
Source Part. Check for Service Valve Caps & anything else visibly wrong with Unit.
Mount Unit Part. Date Capacitor in-case of Warranty. May have to Reform Harness to take new variety of Running Capacitor. Reattach Wires to Capacitor.
Blue = Compressor 3-Terminal
Brown = Fan 1-Terminal
Yellow = Common Wire.
TEST Unit with Circuit Breaker. Does it Function Optimal?
TEST Freon R-32 or R410A with Gauge. Needs Recharged?
Does unit have Super-Heat? Does unit have Piston? Use Super-Heat Chart & Temperature Readings on Thermometers to determine Freon Charge Levels. Charge Unit to Optimum Level.
Pour water down the drain to make sure it isn't slow, and place a drain tablet or two in it. Make sure lines are secure. It's your work now!
Check Air-Filter. Replace if more then '6 months dirty'. Always Date Air-Filter if possible. Check the Blower to see if it is getting too dirty if Filter is bad. If OK with Owner, Sticker Furnace but not if Rental. Tacky.
Reset Thermostat to 70* & Auto-Fan Run. Wait 5 Mins. Success or Not?
Set to 80* if Leaving & no one is Inhabiting/Working or Turn Off. Gather Tools. Replace Handles & Caps. Check & Lock Doors!
Organize Tools. Keep Truck in order. Lock & Latch Truck.
Invoice on Tablet. QuickBooks. Send in Batches to Companies once a week & Customers ASAP. Save Invoice. *Protip* Use AC in Truck. Love AC!

I hope this helps someone! This is a very popular How To video from the looks of it. Thank you for being Cool & helping Newcomers to the Vocation! You did a great job, from what I can tell! Less then an hour is always Nice!
Edited: with advice from Comment by Newstart49 & M A. That's Great Advice!
And burn a J. For you
dude that was really courteous of you, thanks for writing all that.
gotta love it when its just a run cap.
Great video Ralph, nice to see a service call from start to finish. My boss makes us check the condensate drain no matter what, you touch the unit it's yours no matter what the last guy did. Keep up the good work.
Ray
Good advice Ray, I had a drain line come apart last year because the installer barely put the pipe into the fitting. he did glue it but once I was up there doing the service it came apart after I had left. The owner did not blame me instead he went after the installing contractor. it flooded the room below the furnace. #whatamess
It's because of you Ralph I carry I front pocket of anything and everything! Thanks for all your help!
I was very impressed with your professionalism. You gave very clear explanations and obviously know what your doing. I wish you worked in my part of the country.
I remember watching this video 6 months ago thinking wtf is going on now I'm like yup yup yup
that's how i feel like it's gonna be for me XD
If only every call was this simple. Also this probably was 1000% more enjoyable not having to deal with a customer lol. Good video though!
Ralph, excellent front to back service call .........very helpful to new techs ...Kudos!!
Great video. Liked the part about having so much usable junk in the pockets as a service tech. I'm sure every service tech knows a little about this. Thanks again.
I am an hvac tech in new york. And I thought that that I was weird by having so much junk in my pockets. But thank you for making me feel that I am not alone. Lol
hey were you went to school at in New York
Thanks from the bottom of my heart for these much needed free info.
My dad has been in the HVAC business for almost 40 years now. This video is pretty accurate. T&N seems like they do pretty good work and know what they're doing. :-)
been a HVAC tech for two years getting ready to buy my first house none of this would be possible if I didn't make up my mind to go back to school in learn a trade I'm only 24 excited on the future.
Jonathan coleman that's great to hear! It can be a great career if you work for the right company and you always have the option of filing some paperwork and going on your own once you get your mechanical license (depending on your state). good for you. just remember to keep learning and stay sharp. there is always something to improve (especially trying to explain complicated concepts to homeowners). cheers! :)
Love this comment I’m 21 now and in Hvacr school I hope my experience is Similar to yours
Third week of hvac class in trade school, thoroughly enjoyed this video
I love easy service calls like that
one of my best videos. thank you.
Thanks, very cool and wonderful how you walk through the steps in troubleshooting a no call for cooling at that property. Very much enjoyed the detailed video. Take care, Mike Toronto, Ontario
You sir are a scholar! Nice and calculated approach to that call... although I wanted to believe that cond fan was off on psi cycler loll
Within 5 minutes already on the problem, that's a good tech!!!
Thanks for the Video. Did my schooling at the Air-Cond schooling in NYC a long time age needed to re-school and your good.
About to graduate November and cannot wait to learn more!
good stuff. nice and simple way to do a service call.
Great job Ralph! I always wear booties when walking through a customers house. All it took was one dirty foot print for me...
I do have some booties on the truck, but since it was dry outside I didn't get them out.
I wanted to be a Monday morning quarterback. It's funny how everyone notices all the little things.....I think were all guilty every now and again
daobesebeast Mr. Murphy say's your a know it all.
daobesebeast id say the most part would have been disagreeable, LOL
daobesebeast really??
thank's ralph for sharing I love all your work you are a truly Excellent tech! I wish we had tech's like you out here in the sanfernando valley.
Just started doing technical work on HVAC very awesome guide. Much respect stay healthy away from spread of covid.
Great work man! Always face the ladder when descending though.
"Soup to nuts" -- you just made a new tech's first day so much easier.
Thank you.
This schematic gives you an open mind to learn step by step procedure to understand the basic components and operation.The information is very beneficial in the electrical field.With effort and careful application, we will understand the basic procedures,Thank you for your teaching skills.
I bought quick books, installed it, tried it, never really put a huge effort into trying to learn it. Now that I saw you making that invoice on your tablet, I think I will give it another try. 👍
There's an app for that in the Apple Store
At 18:40 the reflection from a wall mirror shows the camera-guy scratching his nuts.
😂😂😂
Brilliant
🤣🤣🤣🤣🤣🤣
thank you for what you do.
Great, great vid. Very thorough and I like your attitude. Am learning HVAC now and am really into the industry. Cheers.
TheBoondoggler I'm glad I could help
Nice video Ralph. Even the easy calls take a half hour.
Hey Rob, your right even the easiest ones are 30 mins long. I did do one today that was 15 mins though
Thanks, please do more. I would love to do this work.
it's the same approach here in trinidad and tobago. great job !!
we never put gauges on until we have measured the temperature of the suction line at the evap coil and the high side too along with measuring the temp differential at the return at furnace after filtration and the supply thus checking the filter same time and the metering device.
then we decide if we need to put the gauges on.
also if you have never serviced the customers home before putting gauges on is probably a good idea after that process i mentioned.
however your doing a great job
we also push permanent hold on T-Stat so it doesnt jump back to programmed temp
Jim Bee Never Tap into a system if you don’t have to
Thanks Ralph for the nice tips
Great video. simple and to the point.
I dont know why but i like watching videos on HVAC i wish i can be as good as yall pro are.
Could you do more of these with furnaces / boilers as well? Its really interesting to see the full process you take to accomplish some of these tasks.
I know every one has a different style and no two service calls are the same but before I worry about checking any charge I usually would verify I have proper airflow so I would check the filter first and make sure I have a clean coil before I touch my charge
Jonathan Cortes he didnt say.he wasnt gonna check it bud....
If it's standing at 30psi on both sides, I wouldn't spend much time changing filters and correlating static pressure drop across the evaporator to CFM until I figured out how the hell all the refrigerant got out and whether it's going to be a leak repair, coil replacement, or complete new install.
james also the fan was moving
Very informative video that should be watched by all new service techs. they will learn more in 28 minutes than 1 week in the classroom !
The reason I showed the whole call in the video was to show what it takes to do the call and it's just not as easy as walking to the unit and changing the cap. I'm glad it was an easy call though
"I'm going to put that in my bag...so I can lose it" got me laughing
Great idea showing the progress from beginning to end. Don't forget to empty those pockets before throwing those jeans in the washing machine. All that hardware could be pretty rough on the washer! Super video -- thanks for showing.
Excellent job on the video and the service call. I would've checked to see if the condensate drain was clear at the evap. coil though. Especially with the humidity levels in Georgia. Also I didn't see a condensate safety switch on the secondary drain port. I may have missed it in the video. At least there was an emergency drain pan installed under the furnace. But the one thing I always check is the drain line on every AC service call. Other than that, excellent job.
Wow...you make it look easy. I may just switch over to HVAC tech from my IT networking job. It seems much easier to trouble shoot HVAC and don't have to deal with computer illiterate clients.
gmlasam Till you do installs
That was cool.. Thanks for sharing the wisdom..
Thanks for the great video. Helped me a lot.
Thanks for the walk through,
Great job and video Ralph !! Reminded me of high school football running the stadium steps,lol. Take care, Brett
I was getting tired of running up and down them.
Thanks for sharing your expertise. I don't know if they still make some condenser fan motors that can be oiled. If so it would have been a good idea to oil it while you are at it. I have a 20-year-old system that has 2 holes in the motor to oil it. Capacitors are a big failure item on many AC units.
He put that key in there so slick lol
Enjoyed this vid.... I love hvac!!!!!
Very thorough and helpful video, thank you.
Good video- I really like that service body on the back of your truck. It looks like you have a lot of storage and can keep fairly organized. Your helper was right on it too- nice work.
Hey Carl I love the truck body!!!!! the side bins stay organized but the back is hard to keep straight. It is a great service body but really not enough room as a install truck. I'm pretty proud of my helper I'm getting ready to lose him because he starts back to school in a few days.
T&N Services LLC. You have the best of both worlds, you can keep most of your stuff organized - while having the opportunity to mess it up a little in the back. lol
Beautiful video tks ,God bless
Great video like always. Thanks for the content
I quit my HVAC career after being in it for 13 years, couldn't make any decent money at it as I was doing 95 percent residential. Got back in to auto parts and now I am working a whole lot less and making close to same money and no slow times. And the kicker is I now also have health benefits. Not sure why this is as I rather enjoyed what I was doing and it was way more rewarding from a hero of the day standpoint but just want to know why company owners are paying less and less for quality help. I'm sure the times have a lot to do with it but now I have thousands of dollars worth of tools I also had to buy just going to waste and it makes me wish I never got in to it. Just my little HVAC rant and I do wish to overall thank you for your very informative video's and I will still be a subscriber in order to stay informed on the latest stuff.
Hvac makes decent money everywhere I've worked so far. If you want to sell some tools lemme know
+Bryon M If those tools are in good condition I'd like to check them out. Its always good to get good tools for a good price.
+Bryon M Should have done commericial, those are steady because the contracts are out there. I make way more than auto mechanics in my city. I wouldnt give up completely, whats stopping you from doing your own service and install jobs on your own? Do side work, give out business cards- make some side money.
You need to find a better company to work for then. I start training next week to be a
residential hvac tech for a good company. Straight up services calls will pay $25.00 for the call and $20.00 an hour. And if you can talk the client into filling out a comment card online you get $3.00 when you send it to them and another $7.00 if they fill it out, good or bad. So that's $45.00 for the call with a possible $55.00 to make from it if it takes you an hour to do it. What I just explained is the worst case scenario at $25.00 for the job and $20.00 an hour. I don't know the AC business yet, but from what I am used to that sound pretty good. And not to mention if you are pulling and replacing parts, then you really start to make some bank. They said I'll get four to five calls to handle a day at an average of $140.00 a call. If I get just two of those average calls a day at $280.00, that's twice what I am used to getting paid. Yes I know, it's seasonal work, but I an good at budgeting my money for the thin times. Plus there is also the aspect of sales evolved, and I am really good at sales and there is a lot of money to be made in that. They expect me to be out in my truck come March, I expect to do very well. I used to do pest control where I had to sell contacts, I sold very well for that
company, until I figured out I was getting screwed. Well, in the end it will be more then I am making now plus it's not hard on the body, so I can do it for a long time to come.
as a residentual lead installer in cali...I've been making over $120k a year the last five years..not bad if u make over 100k as a auto mechanic
It's a fine video and when I made my comment it was not to put anyone down but to pointed out how I would do the service call. The simple things first.
No problem Michael
I didn't think you were putting anyone down.
Great video, thanks for sharing
would have been nice to see how you determined that 19 was the target superheat. I also double check my new run caps under a load (2650 amps bemf method) because we have found new caps that were open or under the rated mics. Good vid! thanks.
I have the same meter, I love it.. good video
I guess the only things I do differently is test the amps of the motor and comp to make sure they are within limits and someone didn't install the wrong size cap (Can use the 2650 x start wire amps divided by voltage at the cap C to S to be sure). I would have poured water down the drain to make sure it isn't slow, and placed a drain tablet or two in it.
I like to check the blower to see if it is getting too dirty- since that cheap filter was being used.
I write the date on the capacitor so if it fails, I know when i installed it instead of having to look it up for the warranty.
You might mention to be sure the breaker is "off" and not "tripped". If it is tripped, do not turn it on until the compressor is tested for ground or there is a grounded voltage source somewhere or it could go Kaboom! LOL.
I also rinse every condenser whether it looks clean or not.
41 years now in HVAC and still going strong.
Good video - enjoyed!
newstart49 likewise, but he did mention that it was a rental property and to my experiece quite a few techies treat rentals differently during serv. calls......
Reggie Milla
True.
newstart49 This was a rental as long as it had a clean filter and it was in safe working condition thats all the management company cares about. Not I agree with it but I can only do what they will allow me to me to do.
was the oem cap...any experienced tech would know this
Anthony F m
Great video. Learned a lot!
PS: Your check engine light is on
Cool video
I like them gauges, I still have the old school analog ones!
they're the best ones...those gauges are absolutely overkill and unnecessary...too heavy. ZERO need for a temperature probe lmao. use your hands. i do commercial, i can't imagine lugging those around on top of roofs. way too over complicated. no need for digital gauges. i didn't even know they existed before this video
+Jonathan Vandagriff that's all I use is the good old hands, feel the lines and hand over the condenser fan! I can pretty much get it right on the money!
Jonathan Vandagriff I use yellow jacket mantooths, I'm 41, and yes joined the digital age, iPad on mantooths, iPhone creating digital hotspot for iPad, when I think everything is good, I Email the shop and customer, with all readings.
Jonathan Vandagriff they're actually pretty simple they have two temp probes one for the liquid one for the suction so it will show subcool and superheat as soon as you hook them up
Thanks for your time and good information.
Very informative video. Thank you.
No need to discharge residual current prior to testing the cap?
Gracias thanks for the tips cant be to difficult to learn and master slowly and surely I'll get it 😉
Interesting video, thanks for posting.
Don't walk through a customers home on their beige carpets without covers on your shoes. And don't change the filter with the blower still operating.... On another note, I'm so glad I live in a place where they don't install the hvac equipment in the attic.
well your lucky because I feel like in arizona almost every house is
+kk fitz I did an attic job today.... stupidest idea ever to put it in the attic
i was treated like a bitch when i did hvac. they called me every name in the book and put me down every day
Will you be my bitch?
vwa 98 Are they like up there in the attic with you yelling at you? I would think they leave you alone and let you work, and at the end of it if they don't wanna pay then tough shit
me too can't wait i start class next month
Ralph good video , I hope that helper of your was running back and forth to the truck for the tools and parts , put him to work lol.
Ralph, do you use a grounding wire on your testo when charging, aparently the refrigerant passing through the hoses strips electrons, I've gotten some pretty strong static shocks after dumping a bottle of R 404a into systems. The static ruined last summer's Testo 557, I sent it back 4 times it still drifts badly, I gave it away and bought a 550 they handed me a grounding wire with clamps. I wish they told me that last summer. I could have bought two 550's for what the 557 cost. I think i'm going to buy another 550 this week for working on multiple units.
You forgot to say that the capacitor may be electrically charged and may sap you.
Im new and that happened to me recently and my boss same day we both had to go home and change pants
Shmariyah H 😂😂😂
How would you take the charge out
@@chaddeeb141 touch the leads at the top
You both should have known better!!!!
Great job
I enjoyed watching your video thank you
Great video.
This video inspires me
nice truck ralph!
i have the same tool bag , thats awesome
Awesome video
well crap I didn't know there's possibly a filter up there in the attic, too. Thanks for the vid!
One thing I always do is check my new capacitor befor installing it. dont happen very often but once in awhile you get a bad one.
has happened to me.....more than once......then i learen to spell em..bar ...assed
Make sure your new cap is the correct one too! You don’t know if the hack (that came out last) put the right one in.
At 3:46 I would be getting a call from dispatch asking "are you almost done with that one, I have a few more that came in", to my response I just found the breaker
😂😂😂😂😂 straight up.
Great video
good video Ralph
Thank you very much appreciate it
Good videos bro. Finish school in 8 weeks for hvac
Are you working yet bro?
+IshockO yes sir, my school got me a job like 2 weeks before school ended. i live in columbia sc, im a installer at the moment at probably one of the best companies out here
+Dj Hooper damn thats awesome! Whats the starting pay?
Heh. Two more years and you can work for yourself, yay!
very helpful
I've encounter two residential package units (mobile homes) so far that have air exiting the condenser grille more horizontal than vertical. Both are cooling good. Fan blade ass'y is about an inch up into the shroud. Someone said the condenser could have been designed that way, but I have to wonder about that, because I see so many other units where the air exits the grille much more vertically. What causes it to exit more horizontally?
Thanks for the video ...forge to check clean condensing...
great vid!!! hey your check engine light is on...
I can't wait to become a hvac tech.
Marlon Thomas Jr Yoo you did it?
Marlon Thomas Jr Well? How is it going?
Me too in school now
Not the greatest example of how to run a service call
I'm on my first month of tech college, taking my first midterm this weekend.. hope I can get through this, a lot to learn in a short time.
I liked " Every Serviceman gotta have a pocket fulla Junk"
Very unprofessional way of carrying spare items!
this guy seems like a really nice guy.
Great video! Thanks for sharing.
Thanks
I like the procedure you've done in trouble shooting the last thing is documentation and invoicing on what you have that's fine but if may suggest I will include FLA checking and cleaning the outdoor unit with pressurized water,,thanks a lot I learned with your video.
