*So amazingly quiet and **Fastly.Cool** in my room! 42db is at a whisper level. I bought 2 and installed myself.Very sturdy bracket and easy to adjust to fit windows of different size. Absolutely fabulous units!!*
The design makes this AC a possible alternative to ductless DYI systems. It works great. The remote control could be more visual aid oriented like a backligh design. Is impossible to see the lcd at least for me. Easy install ruclips.net/user/postUgkx_hHgTlzH3uk31Fe2RVS3xEbXHGaN_z5Tation. Came on time . Great comfort around the house 5 🌟 again. Follow mfg instructions for care and all and this should be the only AC you need for those of is that don't live in new homes with central AC
+Matt, I have followed you for a few years now. My wife and I are now living in a 7,000 sf 1935ish school house in North Alabama that we have been renovating for the past two years. Most of my decisions were based on building science I picked up in your videos. I used the ZipR sheathing, metal roof with air spacing, closed cell foam insulation, wall within a wall to break thermal bridging, and whole house Mitsubishi mini splits. I have 13 heads/zones with five outdoor compressors. I am sure others would have made different decisions, but so far we are extremely happy with our electric bill averaging under $300 per month. My installer said Mitsubishi wants to feature our house in some ads. Could not have done it without your videos.
When I was in Iraq in 2004-2006 as a consultant in the US Embassy, Baghdad, we worked in locally built buildings and they all used these ductless systems. They are very quiet, with remote controls and were great. About time we get them in the US.
I agree, these are great. Very quiet, very efficient. The two I have carry a SEER 26 rating!
We just remodeled our catholic elementary school and installed these in each classroom. Everyone is loving them. They are very quiet and efficient in the classroom. No need for large central units and we didn't have to install ductwork in a 1950's building.
Leroy Nichols That's a perfect use for this product! Thanks for commenting. Matt
I installed a multi mini split system for my house this year and it cut my power consumption in half. It was a a Samsung four zone but I only used it for three rooms I installed it myself but I let the AC guys recharge it for me since I didn't have the tools. These are great systems and they are super quiet. I was a bit worried of placing the outside unit close to my bedroom window but I now know that I don't even hear it running. I would recommend these units any day. And guys if you are worried that they protrude in the inside walls, there is another option known as the Cassettes that are completely concealed from the top of the ceiling. If I can do it, you can do it too but be careful plan right and execute right...
Emmanuel Isanda Do you know how many air handler’s you can connect to the outside unit? And roughly how much would I be looking at moneywise thank you
Are you sure it save your energy bill ...we install one last month and this month my electricity bill was doble the price.!
@@normaramirez3474 which model did you get?

Sir I have some question, I used 165s 5/8 ODF filter drier in AC split type but the copper line in high side is 3/8 , the unit is 28000 BTU , isn't OK did I install ?
I am living in 1100 sq ft condo. What would I need to cool. How long do these systems last? I am retired on a fixed income. I have to make a decision about replacing my old unit.
could you provide an analysis comparing electrical comsumption between 4-ton centralized system and mini-split ( ductless) system (5-zone). i would like to know which is more efficient if the mini-split system is all running the five zones. each 5-zone indoor unit has its own outdoor unit.
this this is so amazing, super cold an quiet and easy to use. easy to put in
Hello Matt. We are building a 650square foot cabin. What tonnage minisplit do you recommend? it will be a dual zone. also is there a specific model that you recommend? Thank you for your time..
How close to the ceiling can you install these?
I love mini-splits but don’t forget about the maintenance each head unit will need each year. You can diy it but it would be a major pain in the butt if you had more than one or two head units or cassettes. If you don’t clean them at least yearly expect mold problems-something not an issue with central ducted ac units. This yearly maintenance is distinguished from the minor yearly maintenance on a ducted ac system (ie coil cleaning).
I'm getting ready to do 6 zones in my entire house. Standard HVAC is outdated junk.
I have a new ducted Mr. Slim 4 ton system on our new house with 5 zones. Thought we were getting state of the art equipment but. One day the rooms are freezing cold and the next it is hotter than hell. We never touch the thermostat. Nobody knows what is happening. It does run quite but it runs all the time.
Matt, Nice video! I think moving forward, all high performance construction will head this way using inverter technology with multiple zoning. I did my high performance home with three Mitsubishi Multi Port units with ten indoor units - 6 ducted and 4 ductless (including one ductless on the patio). The efficiency and the comfort are simply amazing. Quite, NO light flicker and dead-on consistent room temps since you are always moving air to eliminate stratification and matching capacity with the load along with constant dehumidification. Plus, you have the EXTRA capacity (without oversizing/short cycling) if you have a party and have 40 people standing around in your kitchen/family room.
Here are a couple of suggestions: Always use the exterior L-Bracket wall mounts for the outdoor units. This gets the outdoor units off the ground and away from leaves, pets, pests etc. Also, the refrigerant can get a little noisy running through the line set. I'd recommend running the line sets outside an exterior wall and use a gutter downspout to hide them instead of imbedding them in a wall. This keeps them quite and accessible.
My only complaint is that I have had to replace 2 of the 3 control boards in two years. No particular reason, they just died. Under warranty, but still a concern it's going to keep happening.
Al, is right, the best thing is to be able to close the master bedroom door and run it at 68º at night while keeping the rest of the house at 75º.
Great insight, thanks for the personal experience comments. Best, Matt
I'm getting ready to do 6 zones. Mitsubishi
If I were to do it again, I'd go Daikin. I've replaced multiple coils and one compressor. Getting very expensive to maintain. Daikin parts are more, but if you don't need them it does not matter the cost. Ed@@TCJACJ2000
Should Mitsubishi indoor cool only wall units have a release of nitrogen when taking off caps?
Any aircon company that could innovate and make their aircon easy for consumer to wash its internal parts will be the numba #1 aircon and game changer. coz the cleaning of aircon is so expensive nowadays.
Could u suggest me for 185sqt top floor , which is best ac for India .... Mistubushi heavy SRK50zs series or Mistubishi electric MSZ Hp series or Daikin ke FTXF series ,Hot and cold series ...kindly suggest me
love the same ac
i m using Mitsubishi mr slim 18000 btu since 2004 and fall in love
working fine without any problem
but very hard to buy in Pakistan
no latest models available here
We need one for our garage! (hint hint) That would be fantastic for using the rowing machine or doing craft projects...
Matt can you recommend some AC ductless split-system for 300sf commercial space. How many tons should I get and which model? I like Hitachi you mentioned as its self-cleaning. Would appreciate your help. Thank you
300 sf? That's really small. Find unit with lowest BTUs possible bc that's a tiny space. Even the smallest may be oversized.
Question, I have a Commercial Steel building (35x45, 16' ceiling all very well insulated) that we have built a 550 sq ft apartment in. Right now we use a single window unit to cool the living area, not very well either! Looking at going ductless, cooling the living and bedroom area, but also looking to cool the rest of the shop area. The shop area will not need to be cooled all the time, Can a single unit do all that? or would I need a 2nd unit. Thanks for any help.
Mike
May get some issues with stratification that can be solved with a ceiling fan, but your answer is going to fall on how much power is being used inside, how hot it gets outside, and how well "well insulated" is.
Had one installed and it seems like since it was serviced the air does not blow out of the front all the way across the unit. Only from the corners, is this normal? Shouldn't we feel air all the way across the unit?
Looking at finishing a basement room about 240 square feet and doings mini split in South Dakota. Suggestions really cold climate?
They have low ambient models, for really Cold climate, they have supementel heat strips in the condenser
Any updates on this technology? Are you using this is your home Matt?
Nice.. going to add to my all weather room/bar.. gonna be luxury
My condenser coil in the attic has a drip catch tray that goes to a drain. How does this system transport condensation and lower the indoor humidity? In the absence of a drip line from the unit, a separate dehumidifier would be needed in humid areas, which basically will wipe out the efficiency savings....update, I went and 'googled' that, it will need a drain line and if you dont place in a spot close to a pipe, it will need a pump system to carry the condensate to a drain pipe.
From the unit inside the house there is a drain line that goes outside and normally to the ground.
So what's the ballpark price of a unit with/without installation?
I have 5 in my home. They are quiet and efficient. My issue is that they dont remove moisture well. Very often areas cooled by these units are at 65% RH and that smells musty. Mitsubishi has seen them and say they are fine. My central air kept the house at 40% RH.
Yeap. I have the same problem. I'm extremely disappointed.
There's a built in dehumidifier function , have you used that ?
@@davidsuminski4243 unless you have the Wifi Kumo Cloud the humidifier is flawed. You cant set a temperature when you enter humidify on the remote. The unit will just run full blast and you cant control the temperature. With the Kumo...you CAN select dehumidify AND a temp. I believe its a design flaw.
@@rogerwhiting9310 no problem, I understand your concern better now
@@janevance6637 unless you have the Kumo Cloud...which can be installed anytime...you have to just put it on dehumidification and watch it. As per my response...Kumo addresses it.
I see thses in tiny homes , whats cost?
My mitsubishi minisplit has an oscillator button on the right hand side. HOW DO I MAKE THAT STOP ROTATING????? It's making a pulsing noise that's driving me crazy. Thanks
Can anyone connect me with or suggest where I might find a video to hear sound quality and volume of outdoor unit for a Mitsubishi 30K BTU Cooling only PKY-A30NHA or other P Series 19.8 Series Mini-split or something similar in sound quality and volume? Thanks very much if you can.
Our great aunt has a Mitshubishi Mr. Slim Split type air conditioner. She needs part #E22G74451 and our HVAC guys said they found one a few months ago - but it keeps getting delayed. Do you happen to have this part or know if there is a place that has this part that we could order it for her? Thank you!
i am cunfuse between mitsubishi electric and heavy duty i live in india and i need best quality with good after sale service..i like electic one but some people say heavy is better but the company only do trading so they dnt give service from their side kindly suggest which one should i buy 1.5 ton 5 star
I bought 2 MHI Non Inverter Models 2.2 and 1.6, they are great, using them since 3 years. Haven't got a since issue and no repairs. Don't expect service from ME or MHI, but you need a good AC technician to get the best out of them during installation and I don't rely on the company for warranty and service, so if you can manage this then ME/MHI is awesome. Now I am also confused too, which one to buy. Now I want to buy ME, and it has a great reputation too. If it is for a big room then MHI 2.2 is perfect, if you want R32 variant that is also energy efficient then 2.0 T ME MS-JP non Inverter will be perfect.
Sorry if this is a little ignorant.. but would this be an ideal fit if you wanted to just use these in your house instead of a whole home traditional style AC’s?
Yes, that's exactly what you would use this for.
Matt,
What is the smallest unit ? What sq ft does the smallest cover? Can I install it myself?
Thank you
Unless you're familiar with pipe welding and refrigeration, then I think you should leave it to a pro. There are so many little things that you need to do correctly for it to work. Use a licensed and bonded company for everything involving HVAC. Even installing a thermostat can cause problems if you cross the wrong wires together.
I bought a 12000 cut my electric in half 860 squared foot 2 bedroom left my bass boards in for real ly cold nights
I live in a very small apartment and have one of these in here I have the heating and cooling one the coolant is fine but it seems that gets to 10° or lower good luck with the heating you can’t even tell it’s on my apartment like an ice cube
Help me Matt! Just moved into a new house. Our Mitsubishi split doesn’t seem to be doing much. Seems like the HVAC company might be trying to fleece us? Can you recommend an honest HVAC company in Colorado Springs? Thanks.
Why is the heating system not turning on,I'm only getting cool air when I'm trying to get heat. What can I do ?
I am trying to convince my very negative gf to add mini splits and phase out using our old and crappy Central air system. Can you do a follow up. maybe show the home you describe with 8 heads .
Yeah. Need that.
Will this work with a house your going to spray foam
I am a builder and tried very hard to buy a unit but every rep I talked to talked me out of ever doing business with Mitsubishi. All I wanted to do is buy the unit and install it myself. It would have been for my personal home and I do all the work myself on my home. I sub out everything on jobs I do for others and speck homes
Matt, I am getting ready to have a prefab insulated building installed on my property. It will be around 1200 sf. with 12 foot walls (open space within). Is there an option for me that will both heat and cool this space? I have seen these units popping up on school buildings and so on and am very interested in having an efficient means to climate control my new building. Thanks!
+The806Traveler Yes, these Mitsubishi mini-splits both heat & cool and they have a hyper-heat model that still heats with excellent efficiency down to like 5 degrees outside. Amazing technology. Best, Matt
I need help wiring my aspen mini lime condenser pump…. Where does the gray wire go? Says it goes to terminal block 2 …. I don’t know where that is? Took it out before and am 99 percent sure it was wired to the terminal block on the unit. Didn’t pull it from outside ……. Anyone explain this? S1 S2 S3 purple and black into S1 red into S2. Green to ground .. where does the gray wire go? SYs the orange is to be capped.
These are the best type of A/C systems ever! Only cools space that is used, like window units, but uses far less electricity than windows units and especially central air systems.
I have one and would not have one installed in my house if I had known that they are very very expensive to repair and do not last. The repair companies are making a fortune at $193.00 an hour and many of techs do not know how to trouble shoot them. The inverters are more trouble than they are worth.
Sorry to say but we have had a mold issue on the 18500Seer 2 9000 Was Hit with 800.00 no warranty repair not happy
Noel Skrenes We have a unit installed in a boathouse. We are not at the property all the time. The first time of being away for a few weeks, with the unit left on, we returned to a gray powdery mold on many surfaces. Some worst than others. The unit would not remove enough humidity even in the dry mode. Our issue was not the unit itself having mold in it. We had to order a dehumidifier, and that took care of the issue. We bought one with a pump, and run the drain line to the water heater pipe that drains outside. We leave it on, and when the tank fills, it automatically turns the pump on to drain the tank.
Just had my Fujitsu RLS2H (12000btu) installed on Friday.
The objective was to heat a 1300 sq.ft. unfinished open area basement.
During the Winter this area would remain in the 40's f drawing heat from the rest of the house.
As a consequence the heating system was working harder to maintain temperature on the main floors of a 2 storey house.
Even with our fireplace going all day long we could never surpass 68f throughout the house.
The Fujitsu brought the basement from 48f on Friday to 63f today Sunday.
As the basement warmed up over the last 48hrs the whole house has warmed considerably.
We are seeing temps of 75f on the first floor which were never before achievable.
The main heating system of the home, which is a central York heat pump, has not come on since installing the Fujitsu.
I am totally blow away by the performance of the 27.2 seer unit. It has a low temp cut off of -26C.
I see these mini splits taking over from the larger whole house units.
When the time comes I will certainly replace my 11 year old York with a mini split.
If you have been sitting on the fence contemplating one of these units sit no longer.
Do your research and due diligence and buy what's best for your needs and you will never regret it.
Great example of a mini-split solving a HVAC issue! Thanks for sharing. Matt
Captain Canuck Thanks for the in-depth comment! Sounds like your mini is performing well! I've also installed Fujitsu and had good success with them. Best, Matt
Doing a complete multi zone mini split system
Buy the smaller units...6000 or 12,000 BTu’s. Why? They run 24/7 and the smaller units use the least amount of watts on low. Crunch the numbers and run them out for running on low for the year with the different units and you will see the what I’m talking about. The smaller units use 150 watts per hour on low that is 0.36 per day at ten cents per Kilowatt hour. Where as the larger units use 550 watts per hour on low which is $1.32 per day. Buying the smaller units save you $365 a year! They all put out 135 degree heat running on high! And when they get up to temp they all run on low! If you are in a well SEALED area this is the best unit on the market!
would you still reccomend this unit ? or is there any better models your aware of? thank you.
Mr Slim is the best!
When I walk by it in the SUMMER or Winter... I say “ I LOVE this unit!” .... In my 66 years of living I NEVER said that before !
When I go to Florida for the winter it keeps my place at 50° for less than $1 per day on a well sealed 1200 sqft area in Canada.
The only down side is to maintain the warrenty for the 12 years I have to schedule a $150 annual inspection ...that adds another $1800 to the total bill.
Make sure you totally understand all the conditions of the 12 year warrenty before buying any Mitsubishi product.
Bottom line... YES, I recommended this product compared to all the other choices.
I think the 12000 btu uses 1200 w / 240 v = 5 A and the 6000 uses 2.5 A
True on the amp draw on FULL, but what I like is the how little the amp draw is running on low. When the room gets up to temp , I know for a fact the wattage draw is 134 watts for a well sealed room. This is on a 12K unit.
hes says, Shoe room
Where can I buy this in houston?
Amazon Walmart.com Home Depot Lowe’s
How much are they
Only negative on a house with many zones is yearly maintenance. Each wall unit and cassette will require cleaning by a HVAC tech or other professional unless you are a solid DIY er. If you don’t, your mini split can become a mold machine.
I just don’t get why split air conditioners with variable speed compressors are not that prevalent in American homes.
These have long existed here in Asia.
You guys forgot to mention they have very high seer ratings!
hey Matt I've got Mitsubishi mr slim can you tell me about it more I wanna send to my friend he's in las Vegas
+DAXX HEX Check my blog and other videos for more info. Matt
,27 year A.C. & appliance. I retired 10 years ago , wish they (,"Mitsubishi) was around sooner,lol. I RESEARCHED THESE units app.10 years ago and found out in South Louisiana, with high humidity, the performance AC was weak,,( several years ago),,I was getting calls because of lack of cooling.The unit was operating as designed & efficiency was impressive.to me."Has the technology for high humidity areas ever improved?-& how well will these units move the air and reduce humidity?,,I recently noticed many have been installed in chain stores here in the south.I will be interested in a unit after my new shop is completed. Thanks,☆☆☆☆
I want to know why my unit smells like death, 8 year old dirty socks, the worst smell in the world where you cannot even stay in the room. And no one will help me. The AC people who installed it are not helping me and coming up with excuse after excuse. I paid $$$$$$$$$$$ for this unti and very upset over this entire ordeal. I need help. I would never have purchased this horrible smelling unit. And no there are no dead animals in the system. Please help me
Your drain tube is plugged... gently back flush it then spray down the coils and get the water you spray onto the coils freely flowing out the drain tube.
I have mixed feeling about my mini split.
How so? Could you explain....
N Holt same here
It’s needed lots of repairs
I always thought these couldn’t REALLY be as quiet as they say they are in the videos. I thought they’re must be some noise that I will be ever so slightly bothered by. Maybe need to raise the volume of the TV or talk a little louder to be heard. But no! Our Mistubishi mini split is less than whisper quiet. It is hard to tell it’s on when you’re five feet in front of it. And it puts out plenty of cold air. Wonderful technology!
Have had a splitter unit for less than two,years. Internal coil is leaking. Paid company in Charlottesville Virginia that installed unit $500 to find problem and will have to pay same amount or more to install new parts. Part is covered but paid $1,000 after less than two years. I would not recommend unit. Called Mitsubishi customer service. They were indifferent
sorry, going to Mexico and buying my unit, too pricey in US.
Janina Perez pick up some for me.
Ok the installer did a crappy job it never operated correctly and it leaks and it doesn’t work. Its a piece of shit. I m replacing it . Its only a year old and my installer was hired by my criminal contractor. What are my options of getting some money back?
When they run, they run good. Problem is when they get a little old you will not be able to get parts for them!!!! Mitsubishi sucks!! I know I own them.
If u have a flat roof don't get it
This isn't a "review", it's a "promotion."
Wait until the inverter board craps out... All dollars saved on power, gone instantly.
Mitsubishi Air Conditioners are Inferior quality products. It’s easy to breakdown due to fragile parts.
I bought a Mitsubishi Air Conditioner MXY-3G28VA2 on Jan 2018. Now it's Cooling Fan, Control PC Board spoilt. The seller said it's natural damage.
If a human die at his 70s, 80s years old, it’s natural ; but if he die at his 7 or 8 years old, it’s not natural, it’s abnormal.
Obviously this is due to the poor quality of Mitsubishi Air Conditioners.
