Thank you for the video boss I appreciate the veterans like you man I'm in school at Lincoln tech right now I'm EPA certified and I have a ride along comming up with a company that works on p.m systems hope it goes well.
thank you so much. video was flippin excellent. great quality all the way arround. you spoke clearly aswell. very informative on the refrigeration cycle too. good integrity and the end a tribute to the young and old rookies like me.
I'm glad it helped! Comments like this make it worth it, it is why most of us do this. Thank you 🙏, check out my Instagram as well, a lot of good stuff on there and not just mine. Keep doing what you do this trade will pay off 💪
Awesome video. Going into my 2nd summer. Eager to learn as much as possible. Very helpful. Much respect. Subscribed!!! Going to binge watch all your videos.
Nice job on the PM checks! i have about 30, 20 ton Trane RTUs at our shopping centers, i clean them the same way except i never used a small vac to blowout inside the RTU, just cleaned and wiped. After seeing this great PM check i will start to use a small vac. i really liked the attention to detail you give. Thanks man, keep up the great videos.
Absolutely stellar video sir. Thank you for sharing your knowledge. I've never cared for trane much. But you make things a little bit more understandable for a green tech like me.
Love your steam videos. I am not a steam fitter by trade but I am a millwright. So I do tend to dabble in steam heaters from time to time. Keep up good Work I look forward to next one.
Thank You bud! I’m a supervisor at a mid rise haven’t really worked on RTU’s before I have some hallways at 80* F gonna jump on them tomorrow see what I can do.
Great video man. Just came across your channel and will watch them all. I’m a young guy. Just turned 23 and graduate my HVACR program in July. I love this trade. One of the best decisions I’ve ever made was choosing this trade for a career. Just want to say thanks for spreading your knowledge.
Thank you Felipe! That's why I started this, I don't have all the answers or all the knowledge I am learning everyday as you are and just want to share a little bit of the knowledge I do have.
I’ve changed out that same evap coil before, the new coil from trane was manufactured wrong at plant with both circuits tied together, called tech support told them I counted the header circuits they mixed the inlets up, I unsweated and re brazed it in correctly so both circuits where isolated. It happens be aware I notice while pulling evacuation
Great job. If you do get a service call on this piece of equipment after this type of maintenance is done at least you know that it was done thoroughly and you completed it. I worked for this company ( the GM of the branch was a used car salesman ) he would bid maintenances at 20-30 minutes per unit with coil cleanings. If you got a site with 8 RTUs you would get 3-4 hours total to complete it. All the maintenance contracts he sold were just complete garbage, he knew they were grossly underbid on time and he didn’t care one bit. He was looking out for his bonus. Guys like him are terrible but there are many more guys just like him in this industry, unfortunately.
No doubt! Honestly we have some that are under bid just to get but I don't let that change what I do and I have management that understands that, working for service techs is why I've been in the same place for 15 years. Thanks thisblowsballbags!
I have done a few of those and it's much easier than just replacing the fixed header. And your right when the condenser gets dirty the refrigerant and oil gets hotter than normal and that, from what I understand, causes the oil to do cause the waxy build up. Thanks for watching!
Correct these older units only had a discharge port as do some other types of commercial equipment. Also Correct, fixed orifice would be charged per superheat. Thanks Zane!
There is no liquid line service connection on this particular unit. You have a suction and discharge line port to connect to right at the compressor. Subcooling will be a skewed number because your reading discharge pressure, superheat is a more important reading, in my opinion, especially on packaged equipment.
Don't typically Meg compressors unless I have reason to. Most light commercial stuff is going to run till its dead anyway, customers won't pay if something is operational, megger used more on industrial stuff. I use the acid test any time something fails but not typically on a p.m... again unless there is reason to.
@@EverythingHVACR cool. We have a house in souther indiana (Bethlehem). Right on the Ohio river. It’s probably about 20 minutes from jeffersonville. Relaxing 😌
What’s everyone’s opinion on doing rooftop spring maintenances when 5c outside, building temp 20C, I hate doing Resi or commercial, in cold temps, exspecially 410, I live and die by my service reports, pressures temps,
It does suck when it's cold especially when pulling hose to a roof and spraying water around all day. Makes checking charge difficult as well I usually just note on service report the OA temperature and do every check I can to verify it looks ok.
@@EverythingHVACR yup for sure, I hate overzealous service managers that want to start doing Ac maintenance to get ahead of the curve, always it’s going to be a hot summer explanation, meanwhile, spring, 5c or 41f raining outside, 17 seer Ac, or 25 tone rooftop, what can you do with the pressures, all you can do is take DT, outdoor temp, record everyrhing
Good question, thanks, Johnny. It is a skewed number without a liquid port, but it can still be a useful reading. You just have to understand the reading you are taking and interpret it accordingly. So if you assume some pressure drop across your condenser, you can figure the subcooling reading, in theory, will be elevated slightly. Discharge superheat and line temperature can be useful, too. Some chillers use approach temperature, which is another reading that can indicate how well your condenser is rejecting heat.
We are given ample time on our p.m.s it depends on the type of unit to determine how much time they give you, but it takes as long as it takes. The first time I cleaned these particular units, it took a lot longer due to the condition. Now, when I clean them yearly, they take half the time. Evaporators are tough. the best way is to schedule with customers and block off a space below if possible. A brush, compressed air, and light water, if needed, block the return the best you can will work if they are not too dirty.
Thanks for watching PBS #007! I will see what I can do. Sequence is pretty simple, with no economiser cooling and heating calls act just like any other system. With econo, cooling call goes through econo first. Many previous and many too come, thank you for the support and the comment
@@EverythingHVACR Worked there for five or so years. Just moved south a bit and am sitting in a parking lot in Jessamine County right now watching your vids waiting on a call.
Bet the orifice is restricted. When the condensers don't get cleaned well, the oil will begin to thicken as it runs hotter and actually plug the orifices. Trane does have a txv kit for them. Unfortunately, when we replace compressors, sometimes we find out what killed them.
@@EverythingHVACR really that’s not good. I am not the most advanced service tech. I have been in the trade for 15 years. But on this unit I’m working for a friend and he gives me the freedom to learn as a girl I’ll put as much time into it as I need to get it, right. I was thinking of recovering refrigerant, and doing the entire process all over again.
@hookedup9424 txv kit will help, at least it gives you some adjustment. You can try flushing, but that may or may not work. Search orifice restrictions, you may find something to help, but I would recommend the txv kit.
You are right about that, these didn't have economiser installed only a manual damper that's closed or I would have covered that. Those filters always get missed as well. Thanks for watching!
