Keep in mind that larger line set is going to reduce oil return(refrigerant velocity decreased in oversized pipe) If the compressor fails, recommend that line set to be replaced at the same time. Always enjoy seeing the time you take to make it a clean install 👍
Clean filter, clean evaporator and condenser Check temp split (pressures on inverters are kinda tricky without a plug in to the system and checking EEV positions, thermistors etc etc etc)
Hey guys. As much as you all may have issues with keeping that 5/8” Lineset, keep in mind that we do not know whether or not Zach brought this to their attention or not. In residential nowadays it is already difficult to get a customer to do the bare minimum much less a job that will obviously require significant amounts of Sheetrock and paint work after replacement. I will always give Zach the benefit of the doubt as he has shown himself to be one to do his very best in this industry and we should take things into consideration before criticizing every thing that isn’t perfect. The oil return will not be great on that one line, but we can relax knowing that the others are. Zach did his best with what he had and what he was likely given the permission to do. A new line would have easily cost a couple grand by itself after they pay someone to fix the Sheetrock and paint. In the future when they need to replace the unit, let’s let someone build it into a quote then when it is of the upmost importance.
I'm sure he knew and discussed it with the customer. Just read all the comments and I don't see anyone giving him crap for it. Just acknowledging it. Just posting about it because I know a lot of curious people, like myself, read comments to learn a bit more than the video offered. He mentioned he didn't like that it was 5/8", but I'm sure others that heard him say that didn't understand why.
Even with that all said, personally if a customer wont do what I am recommending to make it right, I either refuse the job or have them sign off that problems will come down the road if not done as specified. That I am not responsible at all for when it fails.
Definitely get one of those buckets with a bib in it. There’s really no need to pull the blower wheel then. I personally think they work great. By the way, great job
Please make a video of you cleaning the coils and wheels I just started installing gree. Havent had to do this but I would love to learn from someone like you. That job turned out super nice.
Yes! I am installing a 5 zone Gree. New to cleaning and keeping these units maintained, and cleaned. I want to learn the Right way, the Safe way. Great Video!
We will no doubt see more of these situations due to homeowner installs or handyman installs. All of the money that homeowners think they saved will go up in smoke.
You should get you a Mighty Bracket Mini-Split Support Tool, it basically hangs off of the actual mini-split bracket and holds the indoor mini-split up for you while you tie everything up on the back side. No second partner to hold it up for you, especially if your up on a ladder. Very easy and simple.
That definitely cleaned the install up, but hopefully you have no vibration issues with being mounted on a wood wall. The only walls we mount units on are masonry.
dope as video bro 🛠️🔥 i’m currently in trade school working on getting my EPA 608 ❄️ videos like these motivate me to keep going & pass that 608 & get on the field right away 🔥 Big ShoutOut from NYC homie🗽 #HVACGANG #HvacUpnext 🛠️🧑🏻🔧❄️🌡️
Don't need a mighty bracket. Styrofoam works just fine to hold out the unit from the wall. Its free and thats for me. Don't them for 30yrs that way and never had an issue.
Great content. Regarding your press tool and "calibrate for new size clamp every time" I respect your knowledge but would be surprised if there was anything written about calibration in the paperwork. That being said don't change your ways Zach. Looking forward to the next video.
seems like it would be better to have a traditional split system when you are needing that many different heads. Maybe not possible in this house but thats a lot more things to maintain and fail vs one coil.
Imagine the amount of dirt in the lines , the didn’t purge with nitrogen for sure . Like that diversitech bracket . You’re the best looks way better now
Curious how you weigh out charge on existing system when just pulling back to condenser? If just pulling back to recovery tanks and reinstall to system with adding charge weight how do you ensure no contamination?
I have an idea. Could you out a tiny string on you line cleaner tool and then measure the string. Could also be done with a plastic grocery bag and string and vacuum
Will that 5/8” copper mess with the performance? I have a m/s installed at a restaurant I work at and previous contractor ran 1/2, should have been 3/8. Long run, I think it makes its performance suck. Worked on it last summer, would be some good off season work. I guess I’ll call the manufacturer or text Ralph wolf. Great video.
You absolutly need the "mighty bracket" to install the indoor unit when you have a pre-piping in the wall. I dont know how you've been able to install this easily😮
Thanks & Yes EEV & Variable speed compressors more forgiving on exact charge as long as neither not grossly off They Work Great & or smart enough to try to Keep up tstat set & demand
Yeah could’ve turned them perpendicular to the house blowing discharge opposite and kept them from mounting to the home and still had good access to it all. But not to bad mounting it higher
I would have put both units on the side of the house left he disconnects where they are. Who wants to walk onto their balcony and be greeted with blast of hot air in the summer or cold air in the winter coming out of those units?
I can't believe that was actually done. They show this in the manual with a big red "X" over the picture. But, if you know anything about refrigeration, you don't need an illustration telling you not to do this.
I’ve worked on Row homes that they would turn into efficiency apartments and you had a stack the condensers on the roof similar to this way. It actually says 36 inches of clearance which this one doesn’t look far off but it’s not against code or proper adequate there’s just Specific specifications to go through. Same as a regular condenser. Would say the previous install was completely wrong.
Any advice for a guy (im 23) to get back into HVAC? I kind of didn't take it seriously in school, but I have a G2 license (Ontario, Canada) and SOME experience installing. But my knowledge is limited, I fear ill have imposter syndrome. Should I retake a fast-track program? Or just binge-watch off youtube and learn on the job?
Try and find a company with journeyman who are happy to teach and do good work. Most companies where I’m from see a young g2 holder as someone who is still new, and expect to train them for either tin (308A or R) or refrigeration (313A or R). Just be honest when applying that you’re licensed lacking experience.
your install is not ideal. do you know why? you miss 1 component - anti-vibration pads between mount and condenser unit. this gree and cooperhunters like to vibrate in some conditions, this vibrations go through the wall. how I know? In my house I have brick walls and I have 2 24k BTU units mounted on the same wall. this dumpers saves the day! also space behing unit doesnt looks like recomended by manufacturer, it affect performance. I had to redo mounts after first installers, second was not happy but done the moving since I hang propper mounts myself
That oversized refrigerant line is gonna require a whole lot more refrigerant than what would have been necessary. Which means it has to circulate more, killing the efficiency. You're right, it was a horrible install.
A larger suction line doesn't kill efficiency really, it doesn't add that much refrigerant charge to the system at all. It's a vapor line. What you need to be worried about is oil return with improperly oversized vapor line. Read our comments below for more info on that
@@HVACRTECH-83 I thought that was the liquid line. Yeah it's not gonna require much more if it's the vapor, but like you said oil return is gonna be a problem as the velocity is gonna be too low to carry it back.
@@topher8634there is no traditional liquid line on a ductless system. Both lines are on the suction side of the metering device and thusly are vapor lines all the way around.
@@LordCoolnessocity well the metering device is in the outdoor unit, so both lines are low pressure, but as you probably know, after the metering device it is a low pressure, low temperature liquid. It doesn't become a vapor until it boils from adiabatic expansion in the evaporator. That's why both lines are insulated, you don't want your liquid flashing before the evaporator and you don't want to increase superheat after it.
What kind of luck have you had with the press fits on R410a? I have heard some say never use them, but was curious of your honest real life use of them....Thanks.
Everything is a hammer......LOL.....saying from Ray at Rainman Ray Repairs, but I have to concur. Great job taking a crap install and making it more better (lol).
Keep in mind that larger line set is going to reduce oil return(refrigerant velocity decreased in oversized pipe) If the compressor fails, recommend that line set to be replaced at the same time.
Always enjoy seeing the time you take to make it a clean install 👍
Yep, i would not have done the job if they were not willing to do it right.
Headroom above top unit will make it difficult or impossible to access the boards on the top of that unit.
Plenty of room to get into the top unit
Yea that makes it tough, i would have come down at least 6 inches
Yes, yes it will.
Get a ladder
Mmmm, on top of that unit Board… never seen one on those models.
Looking forward to the next video on how you give a cleaning maintenance on a mini split. Thanks!
Clean filter, clean evaporator and condenser
Check temp split (pressures on inverters are kinda tricky without a plug in to the system and checking EEV positions, thermistors etc etc etc)

Hello,
What are your thoughts on Gree mini splits ?
Many HVAC contractors want to push the brand they carry.
Thank you
As soon as I saw the two condensers back to back. I knew what was going on. Good job my man !

Get a mighty bracket for doing flares behind split heads
Don't need a mighty bracket. Styrofoam works just fine to hold out the unit from the wall. Its free and thats for me. Don't them for 30yrs that way and never had an issue.
@@FlyEaglesFly19111 well done champ
Great work as always Zach!🤝
I remember when I was in TS our instructors told us never blow into a refrigerated line because of moisture ❤
Here in Brazil, we do a lot of installation using this standard. But with the condenser on the wall, doesn't the house vibrate too much?
Can we get a pocket dump vid? Like what you wear in your sheath and whatnot? Preciate ya! 🤙🏼
As always a nice tidy job Zac, all will work well now 👍 Au
Can you press the fittings on soft copper?
What do you think you're looking at?🤦🏾♂️
Quick sling has another wall bracket with adjustable cantilever i use those a lot so you don’t have to put the isolaters behind the arms
Great content. Regarding your press tool and "calibrate for new size clamp every time"
I respect your knowledge but would be surprised if there was anything written about calibration in the paperwork.
That being said don't change your ways Zach. Looking forward to the next video.
it is bs off course
Great video and I like the work you put out but shame HVAC is dying as a trade due to home warranty
Have you had any leaks using the press fitting vs brazing the joints?
Brazing is always the best method. Press fittings are a mix bag for reliability even when done by the book.
When you did your initial reclaim of the gas. How much was in there. Did it have the factory charge still in there. Or was there a leak.
what happened to the young apprentice ?
seems like it would be better to have a traditional split system when you are needing that many different heads. Maybe not possible in this house but thats a lot more things to maintain and fail vs one coil.
Imagine the amount of dirt in the lines , the didn’t purge with nitrogen for sure . Like that diversitech bracket . You’re the best looks way better now
Question, for measuring those line sets theirs 2 lines in each set, 3 sets, so your adding up the length of 6 lines a copper for full length?
Curious how you weigh out charge on existing system when just pulling back to condenser? If just pulling back to recovery tanks and reinstall to system with adding charge weight how do you ensure no contamination?
I have an idea. Could you out a tiny string on you line cleaner tool and then measure the string. Could also be done with a plastic grocery bag and string and vacuum
Good deal … improvising on the fly and cleaning up the ugly !!!
Another great video !
Great stuff. I’m learning a lot off of you. Thanks.

I thought the longer the line set the size goes up next size, and you have to add according to length calculation with oil too.
You absolutly need the "mighty bracket" to install the indoor unit when you have a pre-piping in the wall. I dont know how you've been able to install this easily😮

I would have put both units on the side of the house left he disconnects where they are. Who wants to walk onto their balcony and be greeted with blast of hot air in the summer or cold air in the winter coming out of those units?
Question,
Is there a rule of thumb for line length and weighing the charge?
yes, installing manual tells you what to charge for thay brand.
I sure hope you are not in the field, asking those type of questions
@@serialseatsniffer5610 not in the field only in TH-cam 🤪
