It was very informative and helped me a lot in chiller maintenance. Thanks for taking the time to make this video. Can you introduce me to a reputable institution where I can take chiller maintenance courses?
Thank you so much Kevin, much appreicated. Comments like yours keep my motivated and give me energy. Hope you had a good weekend and have a great work week. Let's get this $
That was nicely done. Do you have any showing how to drain a condensate drain line and pan from a water cooled apartment HAVC system in a Condominium or Apartment building. One with a central cooling tower for all the units ? We have constant problems with the condensate pans overflowing inside apartment units because the drain line constantly gets clogged with "snot".
That's messed up about your wrenches getting robbed. I work in the city every day to and can't leave anything unintended and can't trust anyone. Hope your company got your back and helped you out at least. Your a journeyman and a good one at that. They should help you out. If not they cheap as hell and remember there's hundreds of companies that will take care of you if your a good tech.
I agree good tech or I ll good mechanic. Sorry about ur tools I worked in new york also and was aware of tools disappear quick.....sorry that happened to a good working guy
Why didn’t you purge the air out? That system didn’t have a pump? Just out of curiosity. I’m still in the process of learning chillers, towers and water source heat pumps
Condenser water pump and cooling tower I believe the air vents are tied into the main condenser water loops somewhere in the building. Some water valves or strainer housings have manual air purging ports. Water pumps and cooling towers are required for water source heat pumps /AC systems
Rule of thumb On WSHP Outlet water temperature - inlet water temperature = 10 degrees or lower 95 (Out) - 80 (in) = 15 degrees [dirty strainer or clogged up in the condenser water lines) Higher than 10 = dirty strainer
Those strainer caps are usually sealed with a rubber o-ring. Why do you need Teflon tape. Get a new o-ring & then you won’t have overtighten that strainer cap.
Hi there! Thank you for the video and step by step explanations. I was actually looking to learn how to flush in-unit HVAC systems, since my building has cooling towers but we also have seperate units in each room of the apartment. They used to do the maintenance regularly but since Covid started, we never invited them over. So now I have two units blowing out room temperature air, instead of cold in the summer or warm in the winter. I used to watch the guys do the maintenance but my memories are kind of blurry. My question is, is there a quick way for you to explain me how to do it? I see two valves when I open the AC box inside the wall. I don't know which one is for the incoming line and which is for the drainage. I also don't know whether I should close the two valves before I start 😓 I'd really appreciate it if you could kindly give me a couple of tips that may help me in this cold winter days! Thanks a bunch in advance 🌟
@@minas.a.4393 Hello. Yes, I actually flushed the units by turning off the two valves first. Then detaching the outgoing line from the valve, finding a large enough bucket to collect the dirty water coming from the hose, and opening the incoming line's valve. There's significant water pressure, so I'd suggest anyone to be very careful about the entire process. Once the dirty water starts coming out clean, you can then close the valve and reconnect everything back. Once everything is tightly secured, open the outgoing valve first, and then open the incoming water line. The incoming water line is the one that goes directly into the unit, and that's how I figured my layout. Hope this helps!
Ahhh man it happens working in large buildings with multiple contractors. Especially in the city. Just cant leave anything unattended. Thank you for your words and I totally feel that. These tools are my bread & butter. Just trying to make an honest living out here. Hope you have a wonderful weekend and let's do the right thing👍
Hey thanks Mann.. I'm feel inept at opening the strainer for chambers as I couldn't use the exact force and it drains out my energy for a whole afternoon for this shit🤣
Thanks for your always nice to watch videos bro. I'm sorry to hear about your tools; if you could use some help getting new tools, would you have an Patreon available? Compliments about your editing skills and music choice at the end :-)
sucks you got your stuff stolen. worse feeling ever. just a tip. you can add a garden hose connection with a cap on the end where the cap is and connect a hose and back flush the unit and reclean strainer. allows you get get all the debris in the condenser loop. not a huge problem on copper pipes but if they're using black pipe anywhere in that building or anything other than brass or copper. lines get nasty really fast especially if the tower isn't treated on a regular
hi david, im really interested in this tip. So you connect a hose to the cap and shoot water through the cap to "backflush"? wouldnt this be the same as if the inlet water was just running? as in the hose water is now effectively your inlet water then you remove the hose and let it drain again? this would remove more debris than just draining the pipes after closing the valves?
@@alexanderzhao1457 basically the hose is just a drain down to a barrel to collect the water. close Entering water valve and open return water valve. and open drain valve for your drain hose. it forces all water through the unit and the strainer and out the hose. drain it til water is clear, after which close return and open entering. water coming out should be comparable to the return. if you open return and barely anything comes out or resembles a sink faucet you have a restriction. most likely due to strainer which will need to be cleaned but ive had it clogged up at the inlet or outlet connections on unit or inside the condenser loop itself. after youre confident the system is clear, clean the strainer and put unit back in service.
In my video I mentioned that someone stole my adjustables so I had to use what I had at the time. Haha I know, its looks ridiculous but you need to do what you have to so that job can get done👍 Thanks for watching. Be safe👀
@@Gretathunbergsfart Sir yes sir! Never again will I leave my bag unattended but I cant guarantee I wont forget them inside of a unit and find it a year later 😂 Thanks for the funny feedback. Thanks for watching 🙂
Good attitude dude I super appreciate the learning experience and I hope you’ve been living a good life man
Glad 😄 to see a new video !!! Didn't hear from you for a while. As always well done 👍
I'm back like I never left😎 Haha
Thank you very much👍 New video every week
Whats average cost to replace a 2.5 or 3 ton water cooled air handler unit?
Mann need more of these! On water source equipment. Thanks

Don’t you have to purge the air out before you screw cap back on?
making dirty work look clean⚡️
I like that😎 Thank you sistara!

Don't forget to throw a lock on that disc my dude. You never know...
Dope video btw and much appreciated !
Nice video, thank you, question What type off strainer is that and where can I buy one
Sorry to hear about ur tools I worked in miami also and had to chain the ladder u kno ...tnk u
Thank you for tutorial . But dude do you know meaning of your tattoo?

Bro can you make a video on on how to clean a chilled water Fan coil unit.
Great Video 🎉
My man!
Nicely done
How often should a strainer be clean?
Why didn’t you purge the air out? That system didn’t have a pump? Just out of curiosity. I’m still in the process of learning chillers, towers and water source heat pumps
Condenser water pump and cooling tower
I believe the air vents are tied into the main condenser water loops somewhere in the building.
Some water valves or strainer housings have manual air purging ports.
Water pumps and cooling towers are required for water source heat pumps /AC systems
Rule of thumb
On WSHP
Outlet water temperature - inlet water temperature = 10 degrees or lower
95 (Out) - 80 (in) = 15 degrees [dirty strainer or clogged up in the condenser water lines)
Higher than 10 = dirty strainer
Dirty strainer = High head pressure
I know it’s been a while but thank you!

@@sertacsilbastan thanks! That is what I am planning to do.. but I’m not strong enough to take off the cap! Hahaha
@@minas.a.4393 a wrench would help :)
@@minas.a.4393 I will take it off for ya 💪

Beautiful 🤩
Came to know about the strainer's existence in this video! 👍 Too bad about your tools. ☹️
4:52 a fly spoke and said???
Purging the air? You know in these buildings the air vent never works.
How do you know they never work in these buildings lol Need to do it manually yourself to be safe
THANKS

Why are you using an 18 " Wrench to take off a plug....

Looks like someone went heavy on that pookie last time they cleaned it.
RIP to your tools, bro :(
mashine
I was about to say you needed more torque on that bleeder valve
Lmao! Brought out the big guns! Someone stole my adjustables that day 😭
