Denver should have his own show! He's so funny! Tim Allen (Home Improvement) would be proud of him! He must keep you rolling with laughter - be careful if you are up a ladder with his jokes!
@@prenticelennon3087 thank you
Looks great 👍 Should also show how to connect electrical power to neighbors house without him knowing .
I’ve seen that about 10 times on apartments in the last 30 years and once on a commercial install they all got hooked up to the wrong meter
@@ductlessplushvac Yes it hapens more than one could think,thanks for reply, keep up good work.
As a veteran ceiling cassette installer... Great job on saving and utilizing that template...!👌
Thanks Carter you ready to come install with us?
You guys definitely have the best mini split videos. Thank you 🙏🏽
Thank you for watching and I hope you subscribe to the channel

I can tell Denver enjoys his Job, he's welcome to put mine in but, I'm a little to far out, Great Vid., I had to build a In-Law addition and seriously looking at the heating and cooling options, you answered a lot, Thumbs Up!!
Thank you once more. We travel all over to install so give us a call we're here to help.
Jared
Nice and professional installation ❤
Best cassette install vid I've seen
Thanks
Good job
Love your videos! I wish I lived in CO -- I'd hire you in a minute. I can't find anyone in MA that is willing to do attic ceiling casette installs, or be creative in how they run/hide the lines to make them look good. I can't tell if they are just being lazy and don't want to do the work, or if they don't agree with installing ceiling casettes from below into a cold attic.
Lazy and they don’t know how to do it. The unit can be fully serviced from the room and they never need to be in the attic for anything other than running the lines and controls. Super simple and clean install VS wall units! Mitsubishi is a huge company and they feel comfortable engineering them and mass production of them. We sell 9 out of 10 ceiling units over traditional wall units.
Nice dust collection on the chainsaw!
Right that was a fun video.
Thanks!
No problem!
I so wish you all had included Mitsubishi in the description or the title and I would’ve probably seen your video a few weeks ago when I was finally forced to install my mini split on my own which included the exact same ceiling cassette you all installed. I am not an HVAC tech, but I was forced to do the install myself since I got ghosted by three different techs. It took me two weeks to install the entire system because I had to figure out everything but now our upstairs feels great. I did the ceiling cassette differently, since I was the only one installing it, and had no help. For one I had to move a rafter over, which was very scary, since I had never done anything like that, because the builder made the rafters too narrow. Second, I installed a steel cable on hooks in the attic and hoisted the system up into the attic and slid it down until I got over the area where I needed to drop it in place. At that point, I used ratchet straps to slowly drop it down and hold it in place while I bolted it to the rails that I installed above it. it’s very doable as a one person project, you just have to figure out what you need to do to make that possible.
We can hang them alone in about 10 mins of set-up time. We make bridges and use All- thread. Thanks for watching the video’s
If There's a Will...There's a Way!
I am planning to install this ceiling cassette 9000 BTU in a 15x15 or 225 sq ft bedroom with 3 internal walls and a northeast facing wall having 6'x4' window . This cassette will be part of a 4 zone 36000 BTU system, other zones being two 12K in much larger 450-500 sq ft bedrooms and a 9K in a similar 225 Sq ft bedroom. At least one of the two 12K zone will always be running for heating or cooling at full load.
Since the attic above the room is an unconditioned space which gets to 120 F sometimes in otherwise moderate bay area summer, I want to keep the air handler in conditioned space and hence, the motivation to go for this unit. Any other option , like 6K wall unit, is not desirable due to aesthetics concerns.
I am concerned that the 9K unit ( the lowest size available in this type from Mitsubishi ) may be too big for the smaller bedroom, but also told that the unit can modulate down to 3-4K particularly since it is part of much larger 4-zone 36K system which might make system a good fit and won't cycle too often or cause humidity issues.
Is this inference correct ?
Depending on the heat load your getting in that room a 9k can be a little overkill however The unit can scale itself down when needed. I'm not sure if you know but there is a new 6000k unit just like the 9k unit that just came out, it might be a better fit. I put a new video out on it check it out, please.

Great install video.
Could this ceiling unit be mounted vertically in a wall between joists with drain hole at the bottom? I have extra room on the backside.
No they must be level and flat
I really like these units. I want to install them in my house. Can this be installed horizontally on a wall?
No only on a ceiling install
do you have another angle of what's going on in the attic?
it's not clear or obvious how the cassette just gets inserted into the ceiling and doesn't fall back to the ground after installation. is it being hung from the ceiling joists or rafters?
We make a bridge from the joists and use 3/8” all thread to suspend them and we lock them in with 3/8” nuts and washers.
We have other videos that show what we do.
@@ductlessplushvac Can you please link to that video or give some keywords? I can't find it either.
hi, i have a triple decker in boston with a flat roof. there is no attic. i want to add a ceiling cassette a/c unit for the top floor unit. with no attic, does that mean i can't install this type of unit? how much clearance above the unit do i need to have in order to be able to install this?
8” But you must think about the lines running to the indoor unit. How will you hook them up? How do the indoor unit pipes connect from the outdoor unit. I've installed them as low as 8”, but you have to be very clever with the control wire, piping and drain lines. Most of the time, we use the joist bay next to the one the unit is in and run all of that there. That install can be done 100% sometimes you need to do some additional framing Do it right the 1st time and you'll be happy! Don't settle on the wall units.
@@ductlessplushvac thank you so much! I won't be doing the install myself, my GC's hvac guy will do it. he was recommending putting the condenser on the roof and then building soffits in the rooms where the units will be located, but I wasn't convinced that was my only option. I just didn't understand why a ceiling unit wasn't an option, and just assumed the issue had to be a matter of clearance above the unit . This led me to searching the internet for a better understanding of hvac systems and mini splits, and that's how I found your page. Thanks so much for your prompt reply! It is greatly appreciated.
Obviously the cassette will look better in almost any situation, but do they work as well as a wall unit? My biggest concern would be noise, and if the condensate pump would be troublesome down the road. thanks.
Well it sounds like your a worry wort. Why would Mitsubishi make a unit to be a huge problem considering they are the world leader in this technology?
Great video, how do you guys deal with blown-in insulation? Do you build doghouses for the units??
We build cardboard walls around the unit then cap them
Just installed a 3 Mitsubishi ceiling cassettes in my home - in the bedrooms I am getting a noticeable attic/insulation odor when they’re cooling. I’ve been watching your videos to see if there’s anything you do to help seal the units, but haven’t seen anything - any input? Thanks
Not sure why you're having that issue. Have a tech go look at it. Make sure the drains are good.
getting same issues. there is another person in this chat complain about similar issue. I have 5 heads and they all like that brand new system. Does it smell if only one in cool mode? For me, if I run ONLY one in cool mode and rest on fan/off can't notes a smell. As soon I turn another in cool/auto mode start getting smell on both. Folks saying it is possible common issue with oversize units.
Do all the ceiling cassettes the same dimensions? Are there any that fit 16" on center joists?
They all fit 16” center only the one-way ceiling units, not the square ones.
Hello, I was wondering if these are ever installed on the first floor. I'm having issues figuring out how to get a mini split on my first floor for kitchen and living room. I don't have enough wall space for one on the wall. If it can't be installed on the first floor, do you have any suggestions on what to put on the first floor?
Sounds like you need a consultation. Let someone that's familiar with the units see if that's possible. If not I'm sure there is a option for a different model.
Jared
Did you find anything?
I'm in the same boat right now, trying to find a ceiling unit that van be installed in 1st floor.
Doesn’t the unit need to be insulated in the attic with some type of foam insulation barrier around the unit before the blown insulation gets pushed back. There was a decent amount of gaps around the unit once you put the cassette and hung it in the ceiling (you could see up Inside the attic pretty good) Then you just put the covers over. What about drafts and most importantly when you push the blown insulation back around the unit above in the attic won’t it fall through the gaps into the living space once you take the cassettes covers off the service the unit? Thank you great videos just curious on this issue I see.
No you put a cardboard frame around the unit and cap it with a piece of insulation. The unit is already covered in insulation from the manufacturer.
Hi can you please let me know what is the model number for the 18000btu Mitsubishi cassette with hyper heat one way for the condenser and the inside cassette please thank you
Are you looking for 1-indoor unit only?
Also, find center, send a pilot hole to make sure everything is perfect, then send a screw through the center of the template in the same place as the ceiling then measure each side the same. Cut out around the template screwed to the wall and you're in business.
Yep
That definitely looks better than the cassettes that stick out on the walls
Right thank you for watching
I have a 2 story house. Is it possible to install on 1st floor room?
Yes
Hi
I have 16 inch joist with 14” space between them
Would it fit
What is the width of the template
14-1/4”
It will fit
do you do anything air sealing from the top later?
You seal the grill from below.
How much space above the unit is required? Is it possible to drop the unit, run lines into the unit and then mount? I ask because I have limited attic space above my joints.
9”
@Ductless Plus HVAC so roughly, for a Mitsubishi cassette, you need a total space from the top of the sheet rock about 9" + the height of the unit which is what you'd say in total? About 24"?
9” is all you need , if you can get the tubing, wire and drain line to the location , prefab the connections and place the cassette,then finish the connections
do you have an example video for a concealed unit. i want to replace one furnace and replace it with 5 concealed units on existing duct work. thanks.
We do on a video
@@ductlessplushvac great. which one? Can you help w/ sizing?
Great video. We had one of these installed about 4 years ago, first in the area. We have a musty odor coming from it now (it still cools fine) - filters are clean, pan is clean, blower is clean. I think its pulling air into itself from the joist bay it's mounted in. Are there places to check for a seal where this could be happening?
I would say clean the coil. Then see if that made a difference. Call someone to come look at it.
@@ductlessplushvac Thanks. After watching how you put the faceplate on I checked the screws for tightness and found one in the middle by the drain pan was missing - looks like the gasket there wasn't sealed as a result. I put a screw in there and tightened it down. Will see if this helps. Seems like I notice less musty smell. We also have had issues with water dripping through the grill that I think may have been caused by excessively humid air entering the unit so maybe this will help with that too.
@@user-xc7jm2xd9d nice job thanks for watching the videos.
I guess I'm just lucky! New system installed about 2 months ago all of it has a musty smell, in addition humidity goes up in the room while runs. Any ideas you guys have?
@@peterchaploutskiy2555 your getting some kind of infiltration.
Question- I m building a new home. I like these ceiling cassettes. The house is a basic rectangle. Half of the rectangle is a ‘great room’ the second half is bedroom bath and laundry.
The house is small approximately 1500 Sq ft. I would like to install. two ceiling cassettes in the main room ~ 750 sq ft. One in kitchen and the other at other end of big room. What I have read from Mitsubishi literature is the smallest as for as BTU’s is 9000. Also what product would you recommend for bedrooms. Would like cassettes but I think a little overkill!
The house is being built super tight and and water tight with a above code insulation. ICF closed cell total shell enclosed. A conditioned attic space with fresh inside air from a ERV.
I am going to get a manual J.
What are your idea for this house???/
Yes the smallest unit is a 9000BTU However the system is going to drive down the BTUS. Ductless units are VRF systems and communicate directly with the compressor to send it only the amount of BTUS to satisfy the call for heat or cooling. Do you live in Colorado?
Also, remember if you live in high altitude area your system will be de-rated due to that, what's the altitude your home is getting built at.
@@ductlessplushvac Western NC. 2130’
Ceiling height will be 9’
Your system will work a lot better at the altitude
Where is the best place in a room to install a ceiling cassette? Center of room or on the wall edge or?
Idea video install the new mrcool diy cassette install video.
We only install Mitsubishi systems and a ceiling unit should be in one side of a room thanks for watching the videos we appreciate your comment.
do yall sell and ship units? I live in NH and Im ready to buy a 4 zone ceiling mount system 6-6-6-18
We can yes
can you put them in, if your ceiling is a gable?
The ceiling must be flat
You could possibly construct a box that comes off the ceiling that gives it a flat platform to mount to. Sort of like how ceiling fans and chandeliers are mounted to very steep ceilings.
A Mitsubishi Diamond Dealer contractor has suggested not locating a 1-way cassette over the bed, because the fan noise and condensation lifter may be too noisy. Do you agree?
We don’t recommend that also. If possible put it on the other side of the room.
Can you install these on an angled ceiling
No you can’t flat ceiling only.
Thanks for watching

I’m noticing attics smells coming in from our units. Seems like those side cover plates do not have gaskets and are not air tight. Have you ever dealt with the issue and have any creative solutions?
We seal the grills on the outside and caulk them. You can build a cardboard box and seal them in with a vapor barrier. Some customer(s) don't always want them caulked in but we like the final look. I would check in the attic and see what might be letting in the smell?
I have 5 heads and they all like that. Not sure if that makes any sense when I run on Fan mode than no smell, which makes me do believe it's not a air leak from the attic. also notes if I turn only one on cool and rest are off/fan than no smell. as soon turn another in cool mode start getting smell. in addition humidity spices for instance 56% with off AC, turn on 3-5min getting ~65-67%.
@@peterchaploutskiy2555 clean the units with a coil cleaner and flush them out. It could be your drain system
@@ductlessplushvac would you mind making a video showing the caulking, or the cardboard/ vapor setups you do? Thanks!
@@wesdriggs1269 will do
can i purchse that cassette in washinton DC?
You sure can
Next part please
Do these blow air 4 way?
No they don’t MLZ UNITS are oneway only
Can you install in the wall instead of ceiling
No ceiling only
Sooooo….. how loud is it? Would be nice to know.
Super amazing
Go To Mylinkdrive.com and look up the MLZ-KP12 CEILING unit specifics.
It will show you everything you want to know and more
Why not show the flare and drain connection procedures also?
We have videos on that also
Can you bury these in cellulose insulation once installed ?
You need to make a cardboard box around the unit and install insulation in the box with wall insulation.
what is model # for single cassette unit?
There are (3) sizes
MLZ-KP9000 -350sf
MLZ-KP12000 500-700sf
MLZ-KP18000 1000-1200sf
And the Newest one MLZ-KY6000 for very small rooms 250-or less
All sizing is subject to how much Load affects the room, windows, insulation and many other conditions. You should perform a load calculation to determine what unit will work best for your application.
I never say woops on a jobsite.
Usually comes out like, "oh sh*t" lol
Right, thanks for watching. Shot us a subscription please and thanks.
Jared
how do you get rid of the water?
You hook up a 3/4” pvc line. The unit has a pumping system.
@@ductlessplushvac so you don't need a a little tank or trap then a pump? can it pump up a little or does if have to go down to go out to drain? Thanks
@@chizuck3322 the unit has a pump that will lift the water 19” then you need to run it downhill from there
@@ductlessplushvaccan you have the drain running immediately downhill? And if so, can you disable the pump?
@@boarderjcj no the pump must stay
I didn't see anywhere how the device is mounted inside the ceiling.
It's on the video watch closer next time. Thanks for watching.
@@ductlessplushvac you didn't show it. Just your hand being stuffed in there lol
@@TheSoaringChannel we have other videos that show it then
Anyone experienced in the Raleigh Area? I need a system installed.
We travel!
I am calling your office tomorrow. Maybe we can do a video chat of my project.
what time are you in the office? Or who should I ask for?
@@ductlessplushvac
Screw the template to the ceiling and you don't have to trace anything. Cut around the template 😂
That's funny!
I thought I watched this video already
Thanks for watching.
Not your first rodeo.
Nope
