If you are consider a ceiling cassette system for your home or commercial space, the Mitsubishi Ceiling Cassette should be on the top of your list. This innovative system was introduced by Mitsubishi in 2018 specifically for the United States market. Here are a few things you should consider when purchasing this system.
1) Size and Fit
The Mitsubishi MLZ EZ fit was designed to fit the most common joists in the United States, 18 inches off center. The unique dimensions of US joists makes most ceiling cassette projects more difficult and uneconomical to install for residential applications. Most manufacturers only produce ceiling cassettes that are 24 inches by 24 inches or 30 inches by 30 inches. Mitsubishi was the first to introduce a unit that fits between 18 inches joists. The width is 16 – 11/16 and the length is 38 – 1/16 inches.
2) Airflow
This Mitsubishi system is a one way ceiling cassette. This means that air flow comes out of one vent. The other vent is designed for the air return. The air supply vent can be adjusted to control the swing and angle of the air flow. For most living spaces, you should set the swing horizontally so that the system can deliver precise heating and cooling comfort without any direct air flow to the occupants.
3) Capacity
This system comes in 9k BTU, 12k BTU, and 18k BTU. If you are looking for a system for a larger space, you will need to use the square 4 way ceiling cassette.
4) Noise Level
These systems are super quiet. They can be as low as 21 dB(A) and can operate at up to 22 SEER. Super quiet, super efficient, and super reliable.
5) Waterpump
These systems come with a built in water pump. You can use the built in water pump to discharge the condensate water. There is no need to add an extra water pump to the side the unit.
6) Multizone options
These systems come in single as well as multizone options. You can use them with a condenser that has up to 5 zones. There are also VRF solutions with more than 5 ports.
7) Remote Controls and Kumo Cloud
The MLZ EZ Fit comes with a remote control but some of our customers choose to add the Kumo Cloud app. With the Kumo Cloud app, you can control your heating and AC through any smart phone. Kumo Cloud is compatible with Android and IOS.
8) Warranty and Reliability
These systems come with a 10 year manufacturer warranty and the reliability that you expect from Mitsubishi. A well installed system can last 10 to 20 years.
9) Mitsubishi / Trane / American Standard
Mitsubishi, Trane, and American Standard merged their operations to manufacture and sell ductless mini split products in the United States. These units can be branded as Mitsubishi EZ Fit, Trane Mitsubishi Konnect One Way Cassette, or American Standard Mitsubishi NAXUKS One Way Cassette. All of these products are exactly the same and are in fact interchangeable. They are all produced in the same factory and the only difference is the logo on the front face.
Depending upon where you are in the country, your local HVAC contractor may introduce you these products as Mitsubishi, Trane, or American Standard. If you are located in California and are interested in the Mitsubishi ceiling cassette systems, please call us or visit one of our showrooms. Our team of Mitsubishi specialists are happy to answer any and all your questions.

Never Buy These! There were not designed to be cleaned. Every time mine have been cleaned, the blower shaft has been warped and caused the blower to be off balance while spinning and thumping against the insides. Reframing for the 2' Square units is very easy!
If you can not access and remove a Blower from a unit without touching the Coils; Do not buy them!
I have an old house that has true (not nominal) 2" joists spaced 16" on center. Will this fit?
do you know if the transition from r410a to r454b is done in all the mitsubishi minisplit, I try to find models with this r454b refrigerant, and I only find one the SUZAK36NLHZ, but what about if my need a 30k btu or 24k btu
MADE IN THE USA………..gets my business. I'll purchase about $25,000 in systems and that stays here in the USA.

I have 2 of the 9kBTU ceiling units as part of a 4 head 42kBtu multizone system. One is in a 14×15 bedroom and the other is in a 12×15 with an attached 7×7 bathroom. I’d say there hasn’t been any mold issue and they generally keep the spaces at the temperatures my kids want. Which in the case of my son is around 76° in the winter and 69° during the summer, which doesn’t stress the unit.
I also have a 12kBTU unit in my wife’s open space office and that sorta works ok although all the heat in the house ends up in that space, because it’s on the second floor next to an atrium. So it has to work hard during the summer. Could have bumped the power up there, but she hasn’t complained.
Would these work between floors or only on the top floor?
Is there ever an issue with mold growing on the inside of the unit?
Thanks for the information. What is the best location when the ceiling cassette should be installed to cover living room and kitchen at the same time when the living room and Kitchen located as 90 degree floor plan?
No one has 18” joists. 16” c-c.
I’ve been in home construction and HVAC a long time. I ain’t never heard of 18” centered joists. 16”
Centers (14 1/2”) gap is the standard. This 18” has to be wrong. The engineers at Mitsubishi can’t be this incompetent.
We have this unit but have had trouble with ceiling leaks when our trays fill up and the pump fails to drain. I have heard there is a part we can get to add to the units so that the system will shut off but we have been unable to find exactly where or where to get this. Our contractor has been no help. Do you have any ideas?
Can I have a Ceiling Cassette replace an wall mount? It's a literal eye sore.
Geez, they still haven't changed those remotes. Mine have yellowed after just 3 years, and they aren't backlit. Hopefully these are at least backlit, because the LCD itself was quite poor.
If working on a 2 foot center joist I still prefer the standard cassette as they use a radial fan which is not only quieter but by its very design never needs cleaning.
Why did he say 18 inches on center?
Hello,
I'm installing this in an ADU that has a slanted roof. We've created a box so that the unit can sit flat but I'm wondering how close to the ceiling can this unit be mounted? I don't want that box to have to flare down too much. Is it possible to put this right up against the ceiling?
Are these available in Canada?
This is the only other option I have ever seen other then the One and only
first company air handlers.
Joist 18 inches on center? cassette 16 11/16 it will not fit in any celling !!
In general, I like these, they are less obtrusive than traditional wall mounted units and are mostly quiet.
The temperature on the remote has little to do with the room temperature. My son says it makes a distracting noise at night. We had an issue where in heating mode, my son’s room got up to 90° but putting it in auto mode seems to help.
I put these in the upstairs bedrooms. I think it’d be nice if they sold a 6 kBTU version instead of the current smallest: 9. Also, Mitsubishi should really up there game when it comes to integrating into home automation.
Common joist in the US are NOT 18" on center, they are 16" on center
