Just with this video ,You have proved that you are, at this moment the BEST of anybody out there!!!!! This is one of the golden HVAC videos ever made on RU-vid. Well explained and easy to follow. I consider, Mr. Lavimoniere, that this is your magnum opus of all your videos, up to this moment so far!!!!
This is amazing. I am a hvac student my instructor is an hvac engineer the way he teaches us was confusing and complex but the way you broke it down really help me understand it much better. I would pay you to teach me haha. Great video man.
My Pops was a cryogenic engineer for a liquid helium plant. He could always get our car and home A/C systems spot on. I have tried to understand how he did it for 40 years... this video finally taught me what I never asked Pops as a young boy.
Steve, I have to thank you for all the information you share. Most HVAC guy's won't tell you shit! My latest down turn happened when the outside unit quit. The compressor just hummed for a second before it would cut out, and the fan hummed non stop. Changed out the start/run capacitor. Saved me about a $150.00-$200.00 service charge. I knew enough to give it the ole "HI, how you doin" makeover!
just finished trade school. they did a terrible job teaching. got a great job as a service tech because I spent many hours watching videos like this. great job Steve
I wish I knew of You 10 years ago, Lol...You're really good at explanation of this stuff Steve, train those freshmen, and all You freshmen: listen when this man speaks! You're the man Steve ! best that ever did it -Bart
Excellent video and clear explanations. Great even for homeowners to learn some of the basics of their system. Would like to see more of your teachings.Thanks Steve.
Why couldn't I have a teacher like you back in tech school? Great video Steve. Videos like this one will teach the newer guys the right way to service systems. -Jack
Mr Lavimoniere, THANK U SIR...Everything makes total sense, and Now I understand what's happening... I'm been a HVAC student for 3 months n U sir made everything very easy to understand n I feel very confident do n jobs. Once again THANK SIR.
Wow! Im not an HVAC guy, just a home owner but this video was awesome! You even covered questions I had during the video. Good stuff Steve! You're a great teacher!
Interesting... My old school father in law had me stick the temp gauge on the suction line near the air handler, I we have a TXV.. Units were on the roof so I was charging from inside. now I know why the temp was jumping all over the place. Time to get me a testo and get back on the roof and check the subcooling. This is super helpful
Awesome video Steve! These videos are good tools I wish I had videos like this when I was first starting out. Hopefully guys take advantage of the knowledge being giving to them..👍🏻👍🏻
Steven, Thank you for this video(s) I find your channel very informative. Ive worked as a carpenter but I just recently got into this trade and this help me understand so much better than what ive read so far.
your the man, your info is great, watching you work for the slumlords, like me makes my day can't wait to watch your vid every evening keep up the great work...clifton hottern hell texas
Very Good Video Steven. I have watched almost of your videos and I really find them interesting and well explained. I used to fix A/Cs for the US ARMY and I loved every minute of it. However they no longer have Soldiers fix military A/C anymore its all civilians now. (Government Cutbacks) So I'm Just an Infantrymen now. Anyway I hope to get out of the ARMY one day and try to get back into the HVAC business but for now I'm no supertech.... lol
This is a great video but if you want the fast & easy way to charge a system then Stick a thermometer in the return air plenum. and then the supply air, if you get a 20 degree temperature difference between the return & supply air ducts thats perfect. If your under a 15 degree temp difference the unit is still under charged 17-19 TD is great also.
How many subs you up to now? I know the commercials I have to watch before your video starts are getting better. You got Paul Tuttle Sr popping up now. Congrats on a great youtube channel...you deserve it bud...TMac
hey Steve thanks for the video it was really helpful but i have a quick question lets say you add a lil refrigerant that way it can bring up the sc nd drop on the sh CORRECT?
Lot a the trade schools are garbage look at few before ya commit I learned more ridding in a van my first week on the job then the 7 months I spent in so called school I felt I wasn’t getting anything out of school so I just applied for jobs and got one I’m not saying it’s for you just what I did there are good schools out there ask guys in AC trucks what they did and where they went NATE is probably what ya want that’s what my company now is sending me to class for thanks for your videos they help a lot and make it fun. She’s a leaker mamma!!!
Hey Steve, great video very informative. Question regarding your fieldpiece psychrometer, I read a bunch of reviews saying how fragile they were and the screens were turning...how long have you had yours and any problems? Thanks!
Mike Boyd i have mine and keep it in a safe area,and remove the battery when not in use .i would say take care of it and it will last,,, its not a hammer thats for sure
steven lavimoniere alright I think I'll go ahead and order one. We used sling pyschrometers in school but I like the digital, seems quick and accurate... Into the field at the end of this month! Thanks again for the input and the videos.
steve, in this video when you get to the condensing unit outside your garage, its a ruud just like mine is but mine is a heat pump. at the bottom of the unit there are two yellow wires that lead to what looks to be a reset button mounted on the case and protrudes through to the outside also with what looks to be a cap tube going to the high side line. what is that device and its purpose and where do the yellow wires go and the small cap tube
is there any way i can email you or something i have more questions. my unit currently is not working properly i think the defrost board is shot its getting 26 v in fron the air handler transformer but not letting it out to close the contactor. the high limit manual reset sw is wired in inbetween the boards contactor control output and the contactor itself so until i get a new board in the mail i have bypassed the board entirely and ive beel turning the unit on and off via the air handler breaker
Thanks for the video.Do you a set of hoses for r22 and another set for 410a freon.As in other words do change your hoses for the type of gas that the system calls for.
+Mobileunit6 the more you watch the more you will get it try watching this video it will help you understand ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iCFQC1VSFU8.html&ab_channel=stevenlavimoniere
hello Steve I have a Trane XE 1000 Central air unit, and when I turn on my thermostat to cool my outside unit co.es in and my inside blower blow air through my duct vents ,but Steve the air that blows is not cold air. and when I go out side to the air conditioning unit I don't feel any hear coming from the outside condensing unit fan. do that mean that my compressor is not turning on. I ask that because I seen a video that said the outside fan should be blowing warm air out the fan., And lastly could you give me some ideas of what could be my proem? Thanks Steve for sharing your knowledge with us. Tony D.
Another great video!! Now I have a question.. Since charging is done on the low side, how do you prevent slugging, when charging with liquid? On a unit that already holds a charge, pulsing, in a bit of liquid at a time, should keep it from slugging, but what about a dry unit? Let's say you have a dry unit... An R410a or even an R22 condenser that has zero charge because it came that way or it's been evacuated and vacuum checked, and now you have to charge it... You weight the liquid in, on the low side (Suction), then start the unit... Why doesn't it slug the compressor, when this is done? Might the charging of a dry unit happen differently than what I'm thinking, if so, can you explain? Thanks!
+crabjoe if you add with liquid you just crack the valve add no more then 10 psi above suction and it will flash to gas .your right liquid on the suction side is bad
+steven lavimoniere That I can understand on a running compressor, but how about one that has no charge? I see many instructional videos that say, for example, to add liquid refrigerant to the suction line by weight (based on the info on the compressor), and addition based on line set. Then they say to fine tune the refrigerant level, once it's up and running... Based on that type of info, it sounds as if they're saying ... say for a dry AC unit that says 5 lbs of puron. ... to add 5lbs + of liquid (based on line set) to the suction line, then start it up. Isn't this a no no, since it would slug the compressor with liquid? To me, it what would make sense, in these videos, unless I'm wrong, woule be .... Still based on a unit that calls for 5 lbs of R410a ... While using a scale, add liquid refrigerant to the suction line till there is 1-2psi of positive pressure. Start compressor the slowly add more liquid Puron at no more then 10psi of suction line, until filled based on weight. Am I wrong on my thought? Can you do a video on this explaining the process the next time you have to vacuum a system down? Thanks again!
+steven lavimoniere That's what I was missing!! All the videos I've been seeing seem to never say liquid can be added to the high side, when the unit's NOT running. All they seem to say was "add refrigerant by weight", blah, blah, blah ... "I'm now adjusting the refrigerant for SH/SC" ... "just make sure to use a diffuser or add liquid in slowly (less then 10psi), when adding liquid to the suction side". This makes it sound like the charge can only be added to the low suction side... THANK YOU for clarifying that for a dry unit, not running, that liquid can be ADDED to the high side by weight. filling on the low side is for adjusting the charge level to get it accurate (SH/SC). Still.. How much can the high side hold? Because of what it can hold, is that why techs add to the low side? As for adding liquid to the low side ... Can it be added, while it's off ... then wait for it to vaporize, then start the unit? If this is true, how do you know when it's vaporized? Will the gauges show the same pressure on the high and low side? Please make a video on how to charge a dry unit ... As in how to do it using the suction side and why one might do it on the high side.!!! BTW, this diffuser ... can they be had at the local supply house? I don't see them anywhere online. If you have one, can you show it in one of your future videos? Thank you!!
I'm new to the trade. Would it be correct to say that If the compressor is sweating it would indicate that there is liquid making it back to the compressor? If so would there be any other reasons other than over charge or air flow problems? Or is it just one of the two?
So my hvac A/C unit is either a piston or TXV, correct, it has to be one of those two?, it's a '96 TRANE XE 1000 A/C unit. Which would that be ? It's R-22 and so my question is do I charge by Superheat or Sub-Cool?
txv usally maintain a 10 degree super heat but can varrie so with a 9 degree subcooling you have a full liquid line .and txv if working properly will maintain the superheat
Mr. Lavemoniere, I would like to challenge you to make another video better than this! Trust me it will be difficult to surpass this one!!! And I challenge anybody out there to try to overcome this one!!!
