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.

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!

Purchased: August 2023 - still works GREAT!I youtube.com/post/UgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-… 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!

After countless hours of videos, this is the one to follow. Had no issues with an install. Thanks for your premium instruction!
-
Craig, I have to say this is the most professional and quality full install of a mini-split on YouTube. You did a great job and will help many viewers who want to install their own unit. Have a great weekend! 😀👍
-
Really enjoyed this step by step installation of a mini split. Please keep doing what you are doing. The install turned out really nice and you did a professional job.
-
I've gone through a lot of different Veto bags for my hvacr 90% and this is closer to what i have in mind. Thanks for demo
-
Nice install Craig! Thank you for making this full length video!
-
Can’t get any better than this. Thank you so much for showing us how it’s done. Great video !
-
What a beautiful install. Thanks for sharing your expertise.
-
The amount of detail in this video is amazing. It must have taken him days to produce the video. Great job.
-
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.
-
Great video Craig. I've installed many different mini-splits through the years and your video is well done. I really like Cooper and Hunter. I spent time with them at their Miami facility and they donated a lot of parts and units for our college program. Thanks for doing a great job.
-
Wonderful, it was like a real workshop definitely worth alot. After watching your videos i have installed an ac split unit for my brother with zero experience and it's working excellent. Thank you.
-
Thank you so much for posting this video, it was the best training I found for a self install. Everything was shown pretty much, unlike other good videos that skip "supposedly obvious" steps. I just installed a senville and tested it for the first time tonight :D
-
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.
-
OMG! Thank you for this video! I have a install coming up that requires 5 heads and I was wondering how to run the condensate lines and this video has solved my problem!! Thanks!!!
-
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 have to add yet another note of thanks to the large pile of them in the comments section. Craig, I must have watched this video 3-4 times to take in all of the detailed information you provided on this installation. You helped me immensely as I added a Pioneer mini-split to my garage this weekend. Thanks!
