Nicely done

[@baileysair]

Quick tip when doing all-thread, put a nut on both sides of the cut and then back the nut off of the cut ends. It will re-thread buggered ends every time.

[@RJMaker]

Well Done Britton and Jordan! Thanks for the video.

[@hkhsm359]

Nice job. Quality installation. Keep posting, I will be happy to see outside part installation.

[@ductlessplushvac]

Dude check out our installs

[@serolog]

This was, actually, amazing

[@MyBallzGotShocked]

Nicely surprised at just how nice everything nicely turned out really nice.

[@jivancich]

Damn nice tools and set up❤

[@inhocsigno9151]

Loctite for the nuts and threaded rod, or double nut them? Seems they might come loose with vibration over time.

[@ishaqmd.9026]

Very easy to follow video.

[@Aryan-bn3fl]

Good Installation

[@jerryleblanc3999]

Great videos. Hoping you can help. The condensate drain calls for a VP20 pipe with a 26 mm o.d. But 3/4” pvc is 26.7 mm o.d. Mitsubishi calls for using pvc cement. How do you make this connection?

[@CockyMike911]

Nice video big guy.

[@tjinytjiny6615]

Excellent video..

[@HVACS]

Thank you very much!

[@peterchaploutskiy2555]

Nicely done, acrually. Does anyone knows if drain hose has a check valve?

[@hvac-r977]

How to do the future services? Is it accessible later?

[@Kobe29261]

Thank you!

[@JDT738126]

the eye hooks are a great idea and far less than a L-bracket! What model cassette is that ? The videos say you need at least 16" to install so if that's only 12" wide that is a great option for the old homes in new england.

[@yitzlebo12]

Will this fit between 2x8 joists x 16” OC ? No TGI just regular wood joists ?

[@shenoyglobal]

What do you think of Hybrid Ductless VRF or Daiken VRC for a residential set up in Florida.. is Ducted or ductless way to go?

[@raygamero241]

Thank you you are very helpful can you please do more HVAC videos of charging units Mini Splits Etc you're a smart guy thanks

[@raygamero241]

You're a smart guy thanks for the video can you make a video about charging mini split units multi-zone ones thanks

[@come_on_now]

The navac is awesome. Nylog is also AWESOME! For future, when a service tech needs to replace the flare, make the copper longer AND write torque specs... at indoor AND outdoor units. ALSO, at outdoor unit, write line sets length!! At the outdoor unit, write with a UV pen of SOME SORT! Not a sharpie! Needs to withstand UV

[@Michaelaharoni]

very well made video. I am planning on installing Mitsubishi 5 stations using a branch box. Are you available for consultation

[@billionpod]

What about installing a Mitsubishi EZ-cassette in a finished room? I'd love to see THAT video.

[@trfisher78]

Actually, I actually learned something here actually...

[@josephhathorn1564]

Actually dude

[@wwefan2000geo]

How do you measure where to put the eye hooks

[@LalithBalasubramanian]

Can you install this unit on an angled ceiling or does it need to be flat at 0 degrees ?

[@dmac2890]

How close to a Tv can you mount the inside unit? Mitsubishi says 3' Have you ever seen problems with this distance?

[@786otto]

Looks great except those home depot hooks, Grainger has professional attachments for threaded rod.

[@hvacguy542]

Can you install these on an angled ceiling.

[@robfleming6287]

Put the nut on the all-thread first. Then when you remove the nut, it will clean up the cut threads.

[@ChrisHVAC]

Nice job! I wish our building code was as easy as yours is. We can't use tray cable outside so we use plastic coated MC We also have to strap up the cable, drain and lineset Then again you guys have all that hurricane code we don't have to deal with here

[@cengeb]

It's not tray cable, it's outdoor rated sun resistant , when ya buy the real stuff for minisplit interconnections.

[@patrickknowles5896]

Did the Mits ceiling cassette come pre-charged with nitrogen? It didn’t appear so as there was no release of pressurized gas…

[@TheCablebill]

Does the drain line pitch up from the unit before it travels to the hole in the soffit? If so, would there be a problem with stagnant water during dormant periods?

[@barberhvac3438]

These units unusually come with an internal condensate pump

[@5086nashua]

Nicely done. Does the drain line need to have pitch when it follows the line set?

[@danbiss87]

definitely

[@hvac-r977]

From their AD they said there is a built in pump

[@MyBallzGotShocked]

The pitch looked pretty nice to me.

[@ramytk1]

Hey great video. Not sure if you’ve used these. There is a brand called Sammies. They make a screw that has a 3/8 threaded hole for the threaded rod. They are great to use in applications like that. They come in different styles. Again great video. It’s great to see people keeping care in the HVAC Industry. How do you like the Navac tool? Any cons to it?

[@HVACS]

I will try to answer these in my Q/A video

[@kamenpetrov661]

Nicely done very professional just one safety glasses

[@anthonylombardi3370]

How do yes sheet rock the ceiling?

[@89brayden]

I have knee walls in my attic bedroom. Can these be put on a wall instead of a ceiling?

[@xRedstreak]

They make mini splits purely for the wall, cassettes are just for the ceiling

[@briancurtain3636]

I thought it needed a communications cable. What type gauge wire is that for power?

[@fhuber7507]

He showed the cable. 2 wires for power, one for control and a ground. Look at 3:28 (+/- a bit)

[@rajlovinglife]

Good job if only you would have shown the outdoor compressor/condenser unit .....with Installing the indoor unit plate for final touches..........

[@captainkangaroo4301]

What is the minimum vertical clearance required for this unit?

[@aaronblair9500]

Great question

[@antoniorangel4600]

No isolators. Looks good

[@KentuckyReef]

They make 90degree “sammies” for 3/8” all thread. It would look a little more professional. JMO

[@reluctantprophet]

Chris Durham 👍🏽 yes those eye bolts aren’t designed for lateral forces, I also would have added some wood cross bracing to keep my supports plumb

[@CockyMike911]

When they blow in R30 on top of this set up.... who's gonna ever see it again? Find another reason to be critical of another man's work.... JMO

[@CockyMike911]

This unit weighs a whopping 32 lbs... pretty sure it's gonna hold up just fine.

[@KentuckyReef]

@@CockyMike911 ok speedy, was someone being critical or just letting someone know that the same company makes a different product that would be better suited for the application.. No that’s not a question.

[@GreatMelancholy]

@@KentuckyReef Be more critical. Like the terminations should have spade crimps or at least be wrapped in the proper orientation.

[@nwsvndr]

Can these be used on a sloped ceiling? (What is the max slope?) Thanks

[@stepside2839]

I watch another video and they said “No” because of drain line. They said the units were designed to be level.

[@WheretheJones]

What does the "one way" mean? Is it different from other mini splits?

[@AA-zq1sx]

Apparently it means that it blows only in one direction, or through one vent, as opposed to other square cassettes that have vents on all four sides blowing different directions into the room.

[@WheretheJones]

@@AA-zq1sx ahhh. That makes sense. Thanks!

[@AA-zq1sx]

@@WheretheJones It does direct the air up and down and side to side though, to create good circulation... but yah, only one side of the cassette (on the long axis) has venting. The other side sucks in the air.

[@ssrrocks22]

I would recommend you use the correct hight ladder. OSHA would handyou a nice 500 to a 1000 dollar fine! Just FYI

[@JScott-wz2ug]

"Actually" a good video.

[@StanBenton]

Since the room was already gutted why didn’t you run the line set down the inside of the wall? Had that been my house I would have happily paid a little more for you to drill thru the concrete instead of having to look at that line running down the exterior of the house.

[@ductlessplushvac]

Check out our installs “Ductless Plus HVAC”

[@ductlessplushvac]

This dudes install is ugly as hell no zip ties on the wire and line-sets.

[@gauravharmale137]

can we install cassette ac on 5 metre high ceiling

[@gauravharmale137]

Reply please

[@CockyMike911]

@@gauravharmale137 If It were me, I'd use a ducted unit (not a ceiling cassette) and a 3.5" x 14" ducts down the wall to place my registers at about 10' AFF. Depending on the size of the room, you could place a couple and achieve a very satisfactory result.

[@jasongoertzen]

I hate to be this guy but how do you change this unit out or service it once it's hidden behind the sheetrock. Nice install though!

[@capnclench3786]

We are not allowed to install cassettes in anything other than dropped ceilings where I am. I was thinking the same thing

[@joeshearer1247]

I wonder this too

[@paulgaras2606]

The face plate leaves enough coverage for the drywall to be cut back enough for you to lower the unit for repairs if needed. You can use a “super socket” to take the nuts off. In commercial buildings with water source systems you have to drop units for repairs all the time. Truthfully, I’d rather pull a 30 lb cassette out of a drywall ceiling than a wshp out through a drop ceiling.

[@leekazan556]

Well, I do HVAC in industrial spaces and if you buy a Fujitsu, it will probably last until you retire!

[@AA-zq1sx]

Um... you can go into the attic to service or change it?

[@tonyabdalla]

I played the "actually" drinking came and I was trashed by minute 4...actually...

[@m.lewizz3297]

the space above my ceiling are 12 in deep will this unit fit

[@786otto]

Look at specks think this unit is 7 or 8" deep.

[@ductlessplushvac]

Yes they work in 12” locations.

[@paxlepham]

Nice work. And for 14 dislike, could please point out why you guy disliked?

[@AA-zq1sx]

"This is not at all how this should be done and certainly not a “quality” installation as some have commented. Lines and drain should all be strapped secure. No cement on the drain connection at the unit!? Ever read the install manual? “Be sure to connect the drain hose connecting part using adhesive of polyvinyl chloride family to prevent leakage”. Wow. The thing is swinging free and wobbling back and forth it’s an insult to craftsmanship. The unit should be installed solid on rigid rod, if you can’t figure out how to do that you shouldn’t be installing. This poor customer. Not to mention who’s going to tell the dry wallers the exact dimension of the opening so they don’t drywall up to the edges of the unit. Then the grill won’t fit on and the drywall will have to be cut back. If it’s to be under insulation (especially blown cellulose) there should be plastic barrier covering unit to protect from dust (again, read install instructions if you’re new to this). It’s much better to install lines, drain and wiring in position, then cut the unit in after drywall is painted. Way cleaner and the customers unit isn’t exposed to all the construction dust. Units can easily be removed from below, they’re designed to be installed into finished ceiling. Yes this equipment lasts very well if it’s applied and installed correctly…which this unit is absolutely not. This is not at all how this should be done."

Teflon is ok but has no bearing on seal in this case.

[@sylvandaugert6203]

In some places, it's actually against code to use Teflon on flare fittings. This is because you can easily overtighten as you have reduced the turning resistance of the threads. He compensated by using less torque, but our local gas inspector would have instantly locked the install it he had caught it.

[@cdubs1723]

Nylog is for the mating flares, not the threads

[@MikaelS1977]

You are right but after hearing the podcast Bryan did with Refrigeration Technologies i have changed my mind. I use it on the flare, threads (for sealing) and betwean the nut and flare to reduce friction as to not galling. www.refrigtech.com/nylog-blue/

[@danielg.9578]

@@MikaelS1977 Never put anything on the flare or union face. It is a mechanical seal. Doesn't require any kind of sealant, you lubricate the threads to allow proper torque.

[@MikaelS1977]

@@danielg.9578 Yes in a perfect world :) if ther is any small voids it will help making a seal (yes a good flare dosent have any voids). Watch this AD and do as you wich :) kzbin.info/www/bejne/j5O8fpd8qLl8osk Greetings from Sweden

[@keenanwalker6597]

[@kentwood2914]

Would always be nice to not skip steps...like putting the 2x4 on the other side to make up for truss width too wide for cassette...or did you. See, viewer left to make an assumption. Some degree of off angle is surely undesirable.
