I'm a DIYer homeowner, not a tech. But for some reason I find heat pump technology fascinating even though at my age as an SW engineer, becoming a professional HVAC technician is not in the cards. After my 2nd multi-zone mini-split install where your videos provided most of what I needed to know, I finally bought your eBook. Your videos and free online docs helped me so much that I decided to get your eBook (to learn about checking and recharging a unit), and to understand things better. Also, you've earned the respect and appreciation to get some remuneration for your service, IMO. After getting about 10 pages in where you introduce the basics of refrigeration and the physics, I'm beyond impressed. The diagrams are excellent. The explanations, are clear, thorough, and convey the points succinctly. For anyone reading this, I'm in no way affiliated with these people, I'm just saying if you actually want to understand the core concepts and/or specifics, the book is a worthwhile investment. The eBook is pretty reasonably priced considering how good an educator the author is.

Its good for doing stuff on your home I guess, but not to work as a tech, then you have to deal with using ladders, aggressive dogs, lady's who are never satisficed with the work, customers that hit on you (both women and men), it can create all sorts of drama, is it worth it to spends hundreds of dollars for work you do perhaps twice a year? I'm not sure it is a cost saver, also you have to separate space to keep these tools in working order

Craig, great video. I purchased your book as well and it’s excellent. I do the same setup with one difference. I hook my service hose with ball valve to the side port on my second valve core tool. I leave the refrigerant bottle valve closed but my service hose valve open during final vacuum so that I am vacuuming the air out of my service hose. Then I close the valve on my service hose right before I turn off the vacuum pump and do a decay test. Then I isolate my vacuum gauge, open the valve on my refrigerant bottle, and use the valve on my service hose to throttle in the required charge. The advantage to me is I have pulled out some of the entrained air and moisture from my service hose by subjecting it to vacuum, and I don’t have to wonder how much air I purged out of the service hose using refrigerant to push it out, or lose any more refrigerant than necessary. There is also air between the valve on the service hose and the valve on the first core removal tool that is impossible to purge normally. I’m interested to hear what you think of this setup and if it makes sense or if there is a downside to the way I do it that I’m not thinking of. Thanks

Thank you so much for the clear and concise information. I appreciate that you took the time to both show and tell what you were doing and how it was done.

Thank you for using your training and knowledge to help us "sometimers" be able to diagnose problems with our home systems so we have a better idea of the trouble when we call a tech to come fix it. Or it may be something that we could take care ourselves. Either way a better understanding of the systems and how they work is helpful.

Great video mate,Subscribed. I worked for a union trained tech and can see you know your stuff.

I love your videos. I installed a mini split but messed up one of the flare connections when I shortened the line set, and lost all of my refrigerant. After having several companies come out and give me ridiculously high bids, while berating me for trying to do "this kind of work" as a homeowner, I was fed up. Watched your whole series and learned so much. I realized that of the 4 ac techs that came out, not one knew how to properly evacuate, test and recharge a mini split correctly. And not one wanted to do super heat, saying, "There's no need to do that".

Well, to be fair, handling refrigerant when you're unlicensed is discouraged and even illegal in many places. What you just caused to the environment after letting all that refer into the air isn't something trivial. My take is that you can install the indoor and outdoor unit to your heart's content and then call an HVAC technician to assist you in the piping, leak testing, and charging of your system.

@scasinger123

@@wolfdale_3m Ah, BS, BS and more BS. 2 of the techs that came out planned on letting the rest of the refrigerant out and weighing in the proper amount. I asked them if they used a recovery tanks and they both said something to the effect of "Nah. It's not enough to matter". As for "illegal in most places", two of the techs that came out weren't licensed HVAC contractors at all. They are working for an HVAC company under that license under "supervision". I don't know about the other two because I didn't get their full name. You should probably bone up on EPA regulations before trying spew nonsense. The whole HVAC industry is a racket. I just found a way around it.

Right On Great Video. The wanted 700+ to do the final process of my Pioneer Mini Split process. I just built a mobile office from the frame up, I wasn't about to pay anyone for something so simple. I ordered the valve core removers and the vacuum gauge because hey you need quality instruments. I initially ordered a vacuum gauge and pump set off amazon. Big mistake. I couldn't get the vacuum to go under 1000 microns, kept chasing my tail, thought I had moisture in the new system, pump sounded awful too. Eventually ran and got a 2 stage 3CFM vacuum pump from harbor freight and used a line out of the kit to connect, still chased my tail for hours. Almost regretted taking it on myself. Then sat and thought there has to be an issue with the line because vacuum be going down and then up. Changed the vacuum line and bam it was headed in the right direction. Got it down to 160, went back in the morning and it held at 240. I know vacuum is a huge part of it so, I was happy. I didn't nitrogen pressure test. I know I should have but had to try to skimp due to funds. Also key note, in a 2 ton Pioneer mini split, both the liquid and vapor lines have access ports and they are switched from this video. Liquid line is on the bottom. In any case the process worked well and it is blowing cold and hot. Thanks for the detailed video and links!

Clear and concise!

HI Craig, your videos are the best I have seen. I love this set up because this is the only thing I do when it comes to HVAC, i.e., setting up new mini splits, and this set up eliminates the need for using a manifold gauge set which introduce more potential for leaks and contamination from oily gooey heavily used guage sets. Video request, please do one on the entire Nitrogen pressure test. Support Craigs VIDEOS, I bought all the tools with your links! One tool that I bought not on your list is the metric Master Cool mini split torque wrenches. (The line sets that come with the units are metric or SEA on the OD of the nut, but if you buy a set at a local supply house in the USA the OD on the nut will be SAE but the threads will be the same. Therefore, you would have to buy the Master Cool SAE set). One question, In a brand new system, If I am not adding any new refrigerent in, would I reinsert the valve core after I release the refrigerant from the compressor for the first time after isolating the micron gauge? Thanks again and everyone buy the tools from his links!

Hello and great video! Thanks for making it! Quick question... I noticed that you used a single stage vacuum pump. Do you have any opinions on that vs a 2 stage pump? Is it important or worth it to pay extra for the 2 stage version? You seem so thorough so I figure you might have reasoned this decision before. Thanks again!

hello, thanks for you video. May I know how many PSI do you do for the mini split pressure test? and what is the acceptable drop from PSI? Thanks

wow, good job !

soon after installing my mini split (thank you for that), I had to move the indoor unit to a different wall, so I mounted the outdoor unit on wall stands. in the process of disassembly I unintentionally let out about 3 to 5 seconds of gas. after I reinstalled everything (thank you again), I ran the unit and the pressure was 55psi, so using the steps I added r410a with upside down bottle, til the pressure was about 110psi (i live in a cool area, about 84 degrees then). before and after, the unit was cooling properly. so is there an approximate running pressure? was my method ok or is removing the r410a, then adding by weight the only way to get the proper amount?

There is good info in this video - thanks. Micron, as used here, seems to be a term of trade. As used here, as a unit of vacuum instead of distance, there are 1000 microns to a torr (1 torr= 1 mm Hg). Atmosphere is 760 torr or mm Hg.

Great vids! No one has a video on removing part of the charge on a minisplit that has shorter lines than the built in charge was designed for. Can you please do one? I feel like it's just release the full charge into the lines, start the system, and slowly recover via the suction side of your manifold into a recovery tank while monitoring the scale until you reach the weight that matches the pre-charged weight minus the final weight your line length requires. Is that correct?

Hello , thanks for the great videos. Is there a way to isolate each line set in a quad line set system. Also when you pull a vacuum and hold it overnight should the vacuum go down at all due to temperatures outside? The reason I am doing this is because of a leak. I have the R410a taken out of system in a storage tank and do not know if i should even use this old r410a. If i had a leak in the system before would that have infected the stored /reclaimed R410A. Any help here would be greatly appreciated.
