Mitsubishi Ductless Heat Pump 2 Zone Install

tandnservices.com In this video I install a Mitsubishi ductless 2 zone heat pump.

Nice looking Install Ralph. Speaking of install, I finally landed a job and will be starting this Monday. Excited to be working again after 4.5 years of being unemployed.

[@TandNServices]

Thanks Hank, I know your glad to be back working again. I hope that doesn't mean I'm going to lose a viewer.

[@hvactecster79]

Between the sheet metal videos and the mini-split installs, I could watch them continuously,LOL. Great install and video, nice and clean !! Appreciate it Ralph !! Take care, Brett

[@TandNServices]

Hey Al, I really appreciate the kind words my friend. As far as pressures go the inverter compressors are unlike a normal because the compressor is constantly ramping up and down so there is not really a way to check pressures on them.

[@leanorlando]

Hey Ralph! For "Flaring" Mini Split Line Set, for now i only use the "Yellow Jacket 60278." It is made specific for R410a, and Mini Split Flare, but the advantages of this particular tool is that it gives you that TRUE 45 degree flare that it's required to bond properly and create a more leak resistant flare! I have not had any leaks at all using this tool. It has all the same or similar features as the one you show in this video. I personally NOW cut all my Flares and when possible Braze. cont-

[@TandNServices]

Thanks Daniel, the outdoor is a 2.5 ton 3 zone. I used this match up for a future install. That's the nice part about the inverter you can mix them up like that. Plus they were out of 2 ton's

[@talusranch990]

Excellent videos mr. I'm putting in 2) 9k 30 seer Mitsubishi units. My dad did refrigeration for 40 years and this is a fun project. Gonna braze em

[@TandNServices]

+Dave Haskell have fun with it.

[@EddieLeverich]

Nice job Ralph!! I am starting to like the mini-split idea, can't wait to install one.

[@TandNServices]

Hey Martin, I love Mitsubishi, I really wish that's all I ever did!!!! Don't get me wrong I like doing what I do but if all I ever had to do was install or work on mini splits all day I would be in heaven. I just did another 2 zone today in an office space.

[@steveelim]

I wish the video showed the evac, pressure test, and charge part. With multiple zones, is there some kind of sequence? Do you do evac-test-charge for each zone or is there a common service port for all zones?

[@HVACShopTalk]

Friggin sweet. That came out real nice. Classy work Ralph.

[@TandNServices]

Hey Tom, the job came out really well, as far as the Hilmor brand goes I don't think I will be using another brand I've done crossed the line and now I'm like an addict!!!!

[@robertweeks1171]

These mini split are becoming very popular. Nice job.

[@TandNServices]

Love me some mini splits!!!! Everyone should own one

[@cengeb]

Absolutely, i have 3 going, 4th is going in now. Mitsubishis are terrific, efficient, QUIET, reliable

[@stevenlavimoniere]

great install ralph perfect job for a mini split .i have a simmiler flairing tool but mine is a ridgid

[@TandNServices]

Thanks so much SRG!!!! Getting comments like this really makes it worth the effort when doing these videos. I really don't mind sheetrock as long as I don't have to mess with it LOL. It has never been something I enjoy cutting. Thanks once again for watching and the comment.

[@garcia3953]

As usual a really professional looking job I'm always impressed with your work. I was wondering, when you have some time, if you could talk about the pressures one has to look for when installing a mini split. I can remember something weird or unusual about pressures and line temperatures of the line set when I first looked at a unit running. It didn’t seem to operate like a normal split system.

[@TandNServices]

Hey Andy, I love the Mitsubishi!!!! Although there is nothing wrong with Daikin, I just prefer Mitsubishi.

[@tcphvacr9950]

Great job, Ralph! Line sets look nice, those units are ultra quiet. I see you're trying out the Hilmor brand, have to do a video showing how well they work. :) I've got the 60278 (like leanorlando), and it works pretty doggone good as well. Thanks for the video!

[@TandNServices]

Hey SRG, I forgot in the last comment, the flare nuts on the unit are thicker then what comes on the linesets, that's why I said they should be used. As far as the hole goes, It was purely luck!!!! I wish I were that good.

[@TandNServices]

Hey Andy,I've heard of them but I've had any dealings with them. For me it's either Mitsubishi or Daikin.

[@RayRay-nb7tn]

I have a couple of questions..1. Would you use a tie wrap with a screw mount and screw it to the line hide inside and label your line set with head? 2. How long of a line set is recommended not to go over? May have a 50ft or 100ft one to do with 2 zone 2 head hp. 3. Would you use that polyteck plastic line set pipe or use copper? I know I would use copper, I'm a copper guy not a plastic guy, lolol. Thank you for the video and experience. HVAC TECH FOR MANY YEARS. THANKS

[@RobHVAC]

As always a quality job Ralph.

[@SheetRockGirl]

I enjoyed that! Nice work (and luck) being able to avoid cutting up any more sheet rock. Or studs, yikes. It's a pleasure to watch someone do a job that really knows what they're doing. Why is it better to use the flare nuts? What could happen if you don't?

[@danielzamora3625]

Nice install Ralph and nice flaring tool . Is that outdoor unit a three zone unit. ? T and N Services ROCKS.

[@spacemanwithraygun3933]

I've installed a few of these, gotta be careful brazing can void the warranty. I agree with you on hilmor, they make some good tools. Only thing I don't like with the mini split is the price, the last one I installed cost the owner 3,600.00 dollars for a bedroom. My bedroom at home has a 100.00 dollar unit that costs roughly 50.00 a year, the difference being how much money you are trying to get rid of.

[@TandNServices]

Hey Paltech, I've not ever had to put a cassette unit in but I'm ready for one when it comes along.

[@dmac2890]

I like your videos, you ever install base pan heaters or you order them installed?

[@rmwaseem]

Hey Ralph how much freon charge did you add in this unit , or what super heat or sub cool do you suggest or you use the delta differential temp to see if the unit is properly charged, are there any specific formula's you would use for charging as per recommended procedure..Great video..

[@TandNServices]

LOL Zach, I had tears in my eyes on this job but mine was because of the line hide problems I had.

[@acechoice45]

Sweet job Ralph you make it look easy !

[@andysmechanical7825]

nice install. do you like the Mitsubishi ductless units ?

[@ericgroupe6383]

Great job brother love your videos anyway you could make a short one on flowing nitrogen when brazing ductless units how you set up to purge the flow only one Valve on those style units do you have special fitting for this process thanks Eric

[@agraitrodriguez5926]

Great vid. How do I pull vaccum without getting air sucked in when I release the vac hose? Thanks..

[@TandNServices]

Flares,flares,flares, I wish they were all sweat in but that's the one thing that won't happen so like them or hate them they are here to stay. Hilmor is the BOMB.

[@jerrellstrawn6409]

Connecting of refrigerant lines to a single indoor unit is straightforward. But how are the refrigerant lines from the outdoor unit connected to two indoor units?

[@MegaRadio90]

Hey Ralph!! Excellent video I'm very interested in these systems, so I hope we get see to more as you do them!!! :D

[@SheetRockGirl]

lol I love cutting sheetrock. I wanted to ask, did you deliberately line up that middle hole to a stud?

[@stephenacman3244]

Great job as always!! Very neat work

[@leanorlando]

Looks great!

[@Gamingrelease]

What is your opinion on doing a whole home multi split? I'm a service technician out of Birmingham. We do only a handful of mini splits mainly in electrical rooms and such. But ive never been able to see ones performance in a house servicing multiple areas. I just purchased my first home and this crawl space is TIGHT about 20". The duct work is a hack job, and completely undersized for the 3 ton air handler they have installed. So my options are either rip everything out and start from scratch. Or I've not played around the option in my head to installed 4 mini split heads.. Some guys are saying it would be a huge mistake and others are interested in seeing the results. You seem to do a lot of work with them. Whats your opinion? Thanks

[@cengeb]

new Mitsubishi with heating down to -13 degrees and full 100% heat down to -5 degrees can really do a great job all year. I saved a fortune not running oil furnace all winter, just 3 mini splits, 4th one going in now. Super efficient, 26 and 30.1 SEER. Mitsubishi are terrific, quiet, reliable, EFFICIENT, more than any oil furnace with all the loss in the ductwork, same with central AC, lots of loss in uninsulated old ducts in the house. Mini Splits rule

[@popsmccartney435]

Great video, I am ready to install my first one.

[@deetremper]

HI! I see you put this in in 2013. Where are you located? and how does this work for heating in colder areas such as PA?

[@cengeb]

new Mitsubishis heat down to -5 degrees at 100% around 60% at -13 degrees, incredible Hyper heat models! Use em, flawless, heating and cooling all year, obsolete central furnace and AC, are energy hogs. Inverter driven new Mitsubishis are terrific, super efficient

[@TandNServices]

I'm trying to get you some mini split videos up Brett. Trust me if I could do one a day I would.

[@TandNServices]

Thanks Eddie, after your first one you will have the fever, so be careful.

[@eagletek1]

Outstanding as usual!!! thanks for the info!!!

[@azazza53]

Very nice job, but I do have one [1] question: How many inches down from the ceiling to the center of the 3" hole? Thanks in advance.. ;0)

[@cengeb]

use the mounting plate as the template, on Mitsubishi it's all documented extremely well It's a 2 7/8 hole, it matters, so when you use the through wall insert it's a perfect fit Hole saws come in 2 7/8 carbide for going through brick or old composite shingles from the 70's.

[@SheetRockGirl]

Thanks for clearing that up. As far as luck, that was a good one!

[@TandNServices]

Hey Steven the Hilmor brand will be the leader in HVAC tools before you know it.

[@andysmechanical7825]

ever hear of Sea Breeze ductless splits ?

[@1984juant]

good job man.thanks for videos

[@d.m.4815]

What kind of anchors did you use in the sheet rock and are these units fed with 110v or 220volts?

[@TandNServices]

These are screw in anchors. It's fed with 220

[@HansHVACR]

great professional job.

[@cappuccino-1721]

how many btu's was the 1 in the sky light?

[@awsom70]

Looks nice ralph good job

[@fishbowl7098]

How do you keep insects from building nests in the drain line exit opening near the ground? I can see this being a problem leading to a clogged line? Also,cant a snake crawl in and end up in your indoor unit/hose?

[@azazza53]

loosely wrap a stainless steel screen over the exit point, and check it periodically

[@dwjonz]

Diversitec makes a special end cover for their flexible drain tubing which will keep bugs out.

[@robertodell1903]

If one were to install a multi zone unit as shown in this video, and added an additional air handler to the multi zone compressor down the road, would connecting the new air handler line sets cause any loss of refrigerant? And how would one test the newly installed line sets for leaks, again without losing refrigerant? Please forgive if my question is absurd, as I am not an HVAC pro.

[@dwjonz]

Robert O'Dell You would need to pump the refrigerant back into the outdoor unit. Then after installing the new head,follow the normal evacuation procedures. Then add the extra refrigerant for the extra line set used staying within the maximum distance limits.

[@saljudeh]

how much did that coast over all

[@TandNServices]

Hey Pops, once you put one in you won't be able to wait till your next install

[@TandNServices]

Thanks Elving,

[@TandNServices]

Thanks Wayne.

[@winkhvac62]

nice job

[@TandNServices]

Thanks tecnico,

[@TandNServices]

Thank you CoolasIce!!!!!!

Thanks Quan!!!!!

[@caffeineboys]

14-4 wire at 8 min 07sec? I have heard of 14-3 but not 14-4.

[@xtomo1989]

1 extra conductor for signal

[@cengeb]

there is specifically line made for mini splits, flexible stranded or solid, I've used both, with Sun resistant outer case. Even on Amazon or other suppliers

[@navysuit]

Why didn't you just bury the lineset instead of putting the lineset cover running horizontal along the house? I'm guessing it was due to the electrical running in the pipe. Could you just run conduit under ground to protect the electrical. It seems like it would make for a cleaner install.

[@TandNServices]

I only bury line sets if I have no other choice.

[@navysuit]

+T&N Services LLC. Thanks for the reply. Is there a technical reason for not burying the lineset?

[@maxd4968]

U can but they can Get damaged due to the ground compacting over time! Also it ca lose some of its heat and cool in the ground

[@clintmadill120]

You marked the wall on the wrong side of your level. It should have been on the same side as the window trim.I've done it myself.Oops!

[@tarooaeg197531]

very nice

[@waynemiles7027]

great video,testing123

[@KH-kv2yq]

It looked like the air handlers were not level.

[@bluhuptie]

lol "live for the rest of eternity"

[@leanorlando]

cont- The Yellow Jacket 60278. It's like a dream come true for me Lol!!!! I also now braze where ever possible running nitro through the lines to get more of a sense of secureness between walls. I also Pressure Test with Nitro. Here is the Product link video: kzbin.info/www/bejne/gHqUlJ6Pec5lja8
