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.
Thank you Wade!
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.

Sweet man, thanks!
I just like this video brother or friend. I was looking for a channel that show us or teach us how works a commercial ac or package units.
Thanks Fresh Ride! I appreciate the support.
great professional work
Thanks man!
Cracking 💯💯💯
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
Nice, some of this stuff out here will keep you on your toes. Adapt and overcome! Keep up the good work. Thanks for the support!
Thanks . It was helpful.
Thank you WOLF T! glad it helped

Great video
Thank you sir!
good job well done.
Thanks!
Good stuff bro
Thanks D' VillaGe!
Good video, Thanks
Thank you, D T
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!
Trane has a retrofit to replace the orifice header with a txv setup. Wax from the oil plugs the orifice’s.
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!
Prevention is best procedure 👍👍
Agreed, Thanks John
Well done video, very detailed PM. Thank you
Thank you for watching!
Hell yeah man
🤙thanks for watching! 💯
502 baby!!
Niceee
Thanks Vic
NOW THATS SOME HIGH QUALITY EDITING AND MAINTENENCE! I AM AS MOIST AS THAT COIL
🤣💯 thanks man!
Better than we found it. I like that bro. Another good vid. Are you in Louisville?
Yes I am, you?
@@EverythingHVACR nope.. couple of hours up 65 north. ( Indy)
Nice, I work in Southern IN but no further than Memphis usually
@@EverythingHVACR cool. We have a house in souther indiana (Bethlehem). Right on the Ohio river. It’s probably about 20 minutes from jeffersonville. Relaxing 😌
Night night! 👊💥
Awesome. Do you work on centrifugal chillers much?
Not too many centrifugal or screws. We do more smaller process chillers.
@@EverythingHVACR ah gotcha light commercial. I work on 100-300 chillers sometimes. Trane Centravac or smaller daikin mag bearings
I had that issue with a disconnect. Not all three would engage. Ended up having to replace the disconnect.
Thanks brian! You have to be careful, I've seen multiple disconnects do that, that's why you always check
@@EverythingHVACR so true
So the only Port for the high side is at the compressor? Also this would be charged to a super heat due to the fixed orifice?
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!
Where do you hook up your probes to take SH & SC measurements? Thank you
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.
Thanks watching again
Thanks Scott! 💪
Cool vidéo thx .but kindly remove the arabic translation. Its wrong. Very wrong .
Question! Why need to change the belt ?
And I have Tran unit it looks all ok but not blowing to much air? Can u explain me short please thank you
Thanks ron dod! This was a p.m... preventative maintenance.. so we change belts once a year regardless of their condition.
Do you meg the compressors? fluke1507 is easy to use What about 2second acid test? quick products qt2000 i mean like on an annual
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.
youre now in the 700 club
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
Hw much time are you allocated per unit?Also how do you clean those evaporator coils where return is open to the shop?
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.
@@EverythingHVACR those evaporarors are always a challenge.
could you please do sequence of operation on these rtu,thanks
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
Hey man, I’ve seen you around!
If your from around my way I'm sure you have. You from Louisville
@@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.
Nice! Thanks for the support, maybe I'll see you around.
Ocean waves put yall to sleep but us hvac guys coil cleaning is what we doze off to 😂😂😂😂😂😂😂
I'm struggling trying to get one of these units to run properly.
More information may help me or someone in the comments give you some ideas to help. Start with the basics, read the manual. RTFM
@@EverythingHVACR I did a compressor replacement on circuit one. I weighed in 6.2 pounds of r 22 to name plate. I have a high super heat 40 plus
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.
Every how many months I have to wash the system ?
Once a year is usually good as far as cleaning the coils but quarterly inspections of all other components
@@EverythingHVACR thank you sir 👍🏻
Thank you Abdullah 👊💪
Where are you located?
Louisville ky
You lost me having the panels off in the rain.
Me like
Thank you sir!
😊g
Thanks NY Yankees
Economizer filters always a mess
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!
