Like most people, I watch a lot of videos; this one is excellent! The audio is great (clear and loud), the technician explains and shows each step he performs in a professional and no nonsense manner (he is serious and not goofy, not making stupid and silly faces, eye pops, jokes, or other annoying and unprofessional juvenile antics), and he THANKFULLY does not play mind-numbing background music that overpowers his voice. Thank you. First class presentation.

Purchased: August 2023 - still works GREAT!I kzbin.infoUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!

Hey I own a stud finder sir, worked 9 months under a licensed electrician and did some college for dropped it because of math requirements. I could wire a whole home hot tub, 4 way switches, ground a house but the schools math made me quit! Pipe bending is not a math requirement! It’s simple observation!

[@nhankhuu5643]

It is a math requirement... wtf are you talking about? It's algebra for most things and for pipe bend it's basic math to calculate shrinkage. I'm not here to talk shit to you but I'm here to tell everyone who doesn't know any better what you said is simply untrue.

I came here to review mini split installation procedures. I've watched maybe 40 or more vids from the other youtubers and had high expectations for Craig....... Of course I was not let down. Perhaps the best teacher of HVACR principles on the internet. Thank you Craig for your continued dedication to conveying technical craftsmanship and promoting ethical behavior for the new guys entering the trade.

I'm not even a HVAC Tech. But you kept this video interesting enough for a Homeowner to enjoy watching until the end. I would probably do 90% of this job comfortably. I was just trying to understand my unit better. Thanks for sharing, your an Amazing teacher with an easy to understand tone.

Other than the whole “drill a bunch of test holes” nonsense, this video is super informative, as always.

best install video i have found. Cutting corners on hvac installs is very common, and carries a large financial and environmental price. systems that get onstalled once and run for years without problems get this kind of attention to detail.

[@vovobillinbrazil]

Anyone think Craig is NOT Italian raise your hand... because his are moving like crazy. Awesome explanation of all the steps Craig. Thank you. Brought your book down here to Brazil for reference. Had to rewire everything the "HVAC Techs" did at my new construction. The work they did is horrible. Our builder said they are very good comparatively and expensive. I told him they'd be the hacks in USA. I paid them $1460 Brazilian dollars (about $300 USD) for the install of four 18K units. Our construction crews ran the line sets and electrical wires while building. Pressure test...nope. Vacuum...nope. Wire connectors...nope. One bolt, not tightened holding two of the units on the outside wall bracket...yep. All the ground wires from four units spliced to one that goes to the service panel...yep. Mini splits fail down here all the time, can you guess why? Oh yeah, no license necessary to be an HVAC installer or tech. So for all those that complain in the USA about the steps to become one there is a reason. Thank you again Craig for your years of dedication to this industry. Your information is always presented in a very professional and clear manner. Muito Obrigado from 5000 miles south.

[@criminalbrewing5509]

Ordered mine yesterday, it will take 2 weeks direct from Senville. My head unit will mount to my living room wall which is an exterior wall, right above the condenser unit pad. I hope to make an installation video. The use of the PVC “Sleeve” around the copper, electrical and condensate lines is brilliant, so I will definitely do that. I’ve been watching these installation videos for tricks and hazards and this has been one of the most educational.

[@abdolkarimmehrparvar6583]

Great job man. This makes me much more comfortable installing my new unit.

[@abhinavgaur13]

This video couldn't have come at a better time for me !!! I am so lucky. I follow all videos of AC Service Tech LLC and had already watched almost all videos related to vacuuming lines, nitrogen pressure testing lines, and tips and trick videos. But this one should help me validate, whatever steps I had planned to do based on watching multiple videos, were they correct or was I missing something. Lots of credit to the channel host

[@ps2cho]

This helped me DIY install a mini split. Other than paying for electrician, everything else was DIY and its working fantastic. I really appreciate the attention to detail on the lineset evacuation. I almost guarantee theres tons of hack hvac techs out there who dont bother the small steps like turning the valves on and off to release air trapped in them, purging all the lines properly. My unit is running fantastic...now after $1000 worth of tools to get here between vac pump, manifolds, nitrogen tanks, micron gauge, valve core removers, vacuum hoses...almost feel like I need to install more!!!

[@privateunknown9440]

I'm in the same boat. I dropped some money on the proper tools. I eventually want to put minisplits all over my home and get away from ducted ac. It should be a worthwhile investment eventually. I installed my dad's mini split recently, so that definitely felt good.

[@leojima5747]

Purely clear and straight foward, so educative and to the point. One more thing i liked is ur desire fo a perfect finish appearance on the installations, clean and smart

[@richardroy5437]

I usually leave a little more slack in the lineset where it meets the outside unit. That way if there is a scratched flare or bad flare it has enough pipe to redo it. Nice job.

[@watertech011]

Great job! I appreciate your attention to detail and the clear explanation of everything you were doing. I thought about jumping to another video about half way through but you kept it interesting and I watched to the end. This is a very good example of a professional installation and you made it look easy. I have installed a few dozen Mitsubishi mini splits and I can tell you it's usually not easy!

[@alexx4695]

Thanks Craige I used your guide to do my first install. i added a couple of extra steps to my install and purged the lines with nitrogen before tightening the high side flare nut and after pressure testing I released the nitrogen down to about 1-2 psi then hooked up the vac pump and slowly purged the remaining nitrogen through the vac pump fittings as not to allow any moisture back in the lines. I pulled a deep vacuum very fast without much rise after closing the valves. My unit is a Mitsubishi Bronte 7.1kW Reverse Cycle Split System.

[@Chris-uh3cm]

Craig, mini split today, the homeowner installed and started up himself with a vac. pump he bought. He had the unit running but decided to tighten down the flare nut extra security. He ended up breaking the flare off. He then front seated the service valves. I made the repair and tested with nitrogen at 275 for 30 minutes, no drop in pressure. Put my 6 CFM vac pump on with fresh oil, and it took quite a while to come down to 480 micron. when I closed off the vac pump (just the same way you did) I had a rise to 1300 microns. this was after I vac pumped it for almost an hour! Only 20 feet of line set. What do you think is wrong?

[@Fighter4Street]

Did you use a manifold gauge when you vacuum tested? They say any of those hoses or valves could leak. The micron gauge can also leak like he said, and that is why he uses a little oil on the gauge.
