[@robbyrogillio1052]

Great video man! Where can I purchase one of those open end torque wrenches? Thank you!

[@mdrajibislam6786]

Why Compressor discharge line keep u bent? Please answer.

[@nuc2726]

I'm an HVAC tech. This video has some very important information for me that I have learned from. A lot of these components are the same on a regular Split-System HVAC system too. It's so cool how, no matter what cooling system you're working on, be it a window unit, a package unit, a split system, a mini split system, or even a refrigerator, the same basic compression, cond coil, metering device, evap coil loop is present in all of them.

[@acservicetechchannel]

Absolutely, Thanks!!

[@douglasshackett8747]

Top notch! Thank you...

[@johnschwarz8144]

This is the best breakdown video on a mini split that I have seen to date. The cut outs on the components were excellent. Very well done ! Thank you.

[@InspiredScience]

Hands-down agree. I haven't seen anything else come close. Truly a professional, very well-thought, accurate and thorough overview. Thank you Craig!

[@ColinPopoviciu]

agree

[@ThisIsNotAVideo]

I agree it is the best. I would like to understand more of the design behind the accumulator, though.

[@juansolito1986]

😢

[@spelunkerd]

That's a jaw dropping explanation, no less than brilliant teaching.

[@acservicetechchannel]

So glad that you thoroughly enjoyed it!

[@LuisC202]

This is the BEST Hvac Teacher/Instructor on KZbin.

[@keepthinking2666]

Of over 20 years do an air conditioning and three different colleges for HVAC and multiple certification classes from different compressor manufacturers this was by for the greatest educational video ever made for mini split systems. When I first started to switch over from commercial to do more residential I was never comfortable looking or working on mini splits because I was so confused even when I took the Mitsubishi class it was an entire day 8 hour class that could not even compare to 5 minutes of this video

[@acservicetechchannel]

Thank you so much for your encouragement about our videos!!!

[@moisesc4731]

Why you don’t open a HVAC School?

[@andrewlopin5247]

*Works great **Fastly.Cool** compact and Easy to install*

[@brandonwoods705]

I dont comment often, but this man is a legend. That was high quality information condensed down to about the minimum it could be.

[@hanslawatsch6903]

Thanks Craig for that in depth yet concise tour of the the mini split. I particularly appreciated the cross-section of the refrigeration components and the detail on the sensors and signalling which may assist in basic troubleshooting.

[@chadhiggins8397]

I was looking for a video like this but wasn't really expecting the find exactly what I was looking for, and so professionally done!

[@Noheatcooltech]

Yes Craig 🙌🏾 thank you. We are installing a lot more of these inverters, this in combination with your book is GREATLY appreciated

[@peepeepoopoo1399]

Thank you, Craig! I’m finally achieving a confidence to stick my hands in VRF equipment, thanks to you! Greatest teacher ever.

[@vijayanathanstephen9308]

No one had explained the way you have explained ! And I think your videos are the best so far ! Keep it up !

[@acservicetechchannel]

Thank you so much! I am glad they are helpful!

[@duotecnik]

Thanks for making this, I've always wanted to have a better understanding of my system. I now have a greater appreciation for HVAC professionals!

[@charlieromeo7663]

Best explanation I’ve seen. Great job. I have the same specialized torque wrench for flared fittings. But beware, it is not calibrated in both directions. It’s pretty easy to get crossed up in the field so make certain the decal on is always facing up when rotating clockwise.

[@thetruthserum2816]

Perfect explanation on why exactly overcharging a mini split is detrimental to the compressor. Subbed!

[@goodkao]

Wow! You teach us better than our Hvac instructor. I love all your videos. Thanks! 🙏

[@graciemiller9596]

Thank you Craig, I’m not a HVAC man but have installed 4 of these so far on my house. About to do another on new home that I bought. I find them very interesting.

[@ericbrobst8160]

Great video Craig! More mini split content please!

[@webluke]

These videos came out 1 month after I installed a Cooper and Hunter minisplit in my office. Its nice to see the insides and how it all works. I do plan on adding more minisplits to my house after I finish my solar system. With net metering of electicity I hope to save up the solar power and use it for cooling and heating saving me a lot in the winter on propane and more efficent than a swamp cooler.

[@gyenisattila1069]

Köszönet a kiváló szemléletes, és érthető bemutatóért, nagyon hasznos volt! Sajnos az iskolákban sokszor, nincsenek ilyen jó bemutatók.

[@camiloramirez3367]

You're the real HVAC GOD, Mr. No more to say than, thank you.

[@SirGicano]

Thanks! Nice cut-away component views. Direct to the point explanation.

[@boehmertechnician8740]

Thank you for explaining this alot of people in the industry kno nothing about mini split systems few will do the research.

[@robertwasswa1631]

You and AC or Refrigeration are just one. You're just the subject. Thanks for the explanation.

[@BrokeYuppie718]

This guy really really knows this profession intimately I’ll definitely hire him hands down wish he was in NYC

[@jhoneduardogilortiz5731]

Thank you, it's the best KZbin video about HVAC systems

[@rafaelcassiano1366]

Damn BROOO... this is the best video that I watched in my entire life, I have 12 years experience, nice job

[@Your-Local-Insomniac]

Alway learning!! You do an amazing job explaining on both technical side and procedure side.

[@jimmylanders2175]

Hey Craig this was a great video and one I have been looking for on U-Tube. Could you do a series on troubleshooting boards, components and errors. For mini-splits.

[@waleneliyata1252]

You are the best teacher i have ever seen..❤❤❤

[@john0119]

Thanks for sharing Craig 👍

[@brianmcdermott1718]

great job as always Craig!

[@austinkerr6197]

Thanks for this crash course in mini split system my confidence is way better

[@kyleh1974]

I worked on a Daikin that also had a miniature liquid receiver. Good content and thank you for everything you do to help the trade!

[@moleisrich1]

I don’t have one but I watched anyway. Very very interesting break down. Thank you

[@stephenbuckley2186]

many thanks, this made things much clearer to me. I have had a variety of different flashing lights on occasion the most common being the run and timer lights flashing twice every twenty seconds or so indicating rotor lock, open phase or damaged wire, and having read the installation docs it clearly says do not install in places where the wind can blow into the fan exhaust as this can cause a high pressure fault and seriously damage the compressor. The place the company installed one of my units does get wind blowing directly into the fan exit and is sometimes strong enough to blow a 2 kilo lead chimney cap off. I only recently associated the fault with windy days. The company seemed unaware of this and denied it could happen. wanted me to pay £250 to come look at it and £850 to fit a new compressor which is rather more than buying a new unit. It does still run but often shuts down particularly when it has reached a temperature and shut down but fails to restart, I can hear it going chug chug and the whole outdoor unit shakes a bit. Dont know quite where to go from here but it has clarified things for me a lot so many thanks again for an excellent video.p.s. I have now built a bit of a screen over the outside unit to deflect the wind a bit.

[@caryandgrace]

Keep the videos coming. Thank you sir!

[@stephenb5757]

Awesome video. This video is probably the best visual I’ve ever seen. I loved the cutaways of the different parts of the unit. Keep up the great videos!

[@acservicetechchannel]

Thank you so much Stephen!

[@maxgrind438]

Good job man You are the greatest in the world. I hope to see you oneday.

[@Fred-zt6gf]

You literally make my life not suck as much. I’m a new service tech who hasn’t really been taught mini splits and I’m at a call as we speak trying to figure out how it all goes together so I can articulate a good reason why it’s not working right.

[@tainelio9266]

This is awesome, excellent explanation. Thank you

[@djpaulk]

I'm a commercial Fridgy, 30+yrs experience. Your explanation in less than 20 minutes was almost flawless. Beats any TAFE teacher i had. There are too many people who are clogging this utube up with crap. But you are one of the few who doesn't. You sir, should teach apprentices at a technical college! Excellent vids. Paul from Oz

[@acservicetechchannel]

I'm so glad to hear you appreciate what we are trying to do, thanks and means a lot!

[@halledwardb]

Yes I have to say, Craig is better than the school I'm in now. Craig should run some for of academy. He already does, but maybe something with a piece of paper attached to it.

[@jonathanteller6550]

I have a minisplit that works great in heat mode but only blows ambient in cooling mode. Do you think I have a bad pilot solonoid?

[@davidhunt4291]

I am the jerk that gives so many presenters a hard time so when I tell you that I'm impressed you can believe it matters. It is so nice to have someone that knows the subject and speak well, congratulations on a video well done from an engineer.

[@scrivyscriv]

Thanks for the video, it's quite helpful!

[@mvanderw379]

Very well explained, many thanks.

[@acservicetechchannel]

Glad it was helpful!

[@stan-r]

Craig, thanks so much for all you do and for the servicing guides and quick reference cards, they have been very handy. I recently started a new job in a resort that has Samsung mini-splits in hundreds of rooms. I have been looking everywhere for troubleshooting procedures for these things and I am not finding anything that really helps the average technician isolate problems quickly. I enrolled in the Samsung academy, but the troubleshooting guidance is vague and doesn't really help with pinpointing the cause of failures quickly. Maybe mini-splits are too difficult to troubleshoot in the field. I've tried to locate procedures for compressor or EEV failures, but I'm not finding anything. I was wondering if you could start making videos on these units, they seem to be the latest trend in HVAC, but obtaining training has been challenging. Thanks again for all the expert guidance you provide.

[@larkhill2119]

Been a year however, there is a channel called "Taddy Digest" He has a lot of quick simple videos on Samsung mini-splits faults and service.

[@chriscermak3188]

Great video Craig. You seem to be the only one explaining Mini splits. There's not much info about them out there other than installs.

[@frankgall6]

This is a great video. We depend on tech support a little too much on ductless troubleshooting. This is great

[@user-sc7ll3zl2e]

Beautiful example of superb instruction! Amazing how long the 990 micro farad total for the trio of outside unit fan caps can hold their 300-volt charge after a Samsung Windfree is powered off! Good to discharge it intentionally.

This is the best explanation I've ever seen. Brilliant teacher !!! Way to go!

[@targetshooter3751]

Thank you for a Super Excellent explanation! I would like to see a future video explaining the error codes in depth, and what they mean - including troubleshooting the HP (P6) Sensor. Why are the error codes different between the inside unit and the outside unit?

[@patrickg875]

Awesome explanation. Thankyou!

[@planeaddiction2560]

I found the issue on a senville unit by watching this video, the K Type sensor was burned by touching the condenser piping , it melted the clear polycon tubing and chaffed the wire, this heat made the board believe the outdoor temp was alot warmer and caused the compressor to reduce the inverter gas at a lower temp causing the indoor head to blow cool air instead of hot air during a minus 7 temp today. Thanks for saving my job today
