Wouldn’t touch a Fujtsu with a ten foot pole. Had a factory defect with one of the the several units installed in my home. Customer service is non-existent. If they work – they work great – but if you have a bad one, Fujitsu will not help with anything but the part. The Fujitsu certified rep who installed it, attempted to fix four times before giving up. Charged me for each service too. Had to have another Fujitsu certified tech come figure out that air handler was leaking coolant. He had to essentially rebuild the air handler to exchange leaking part. Of course I had to pay for the labor, coolant, problem diagnosis… Fujitsu would’t even respond to my email describing my situation other than to send me a copy of their warranty. New Fujitsu tech says it keeps him in business.

Decided to go with Daikin 24LVJU.. what swung it for me is the 12 year warranty, and my installer is including a Daikin labor coverage for the 12 years also.

I bought a vacation home in July 2013 in a Central Oregon. It had a Daikin split ductless heat pump installed
In May 2012 for $6,955 by the former owner – and it never worked since I purchased the home. Since there is
Electric baseboard heat and a wood stove, I just didn’t ever use it.

Since it is a vacation home we use it sporadically. Yesterday it was in the 80’s so I called the company
Who installed the system, and the tech who came out from Bend Quality Heating said the refrigerant
Is low.

He quoted a repair price of $800+ and told me if the previous owner "did not register the unit the warranty
Was void."

My thought is if they charged $6,955 to put the unit in, and I read about thr great warranty that Daikin has
AND since the unit is 3 years old – why should I be paying $800+ to have it repaired when it hasn’t
worked properly since it was one year old!

Sorry for the difficulty. A few thoughts.
A) double check the warranty
B) Registration or not the Daikin product should carry a minimum 5 year warranty on parts (not labor)
C) $800 for what repair? Repair leak? Refrigerant is not a consumable and therefore should not be low. Low freon means either the unit is leaking refrigerant OR was never charged correctly at the get go OR could mean the unit was mis-installed. Though could be hard to prove after 2 years.

Good luck with your unit! Once it works it will be great.

I’m going to install fujitsu or carrier ductless. ..what should I go with?

Typically we recommend going with a major Asian Brand but carrier’s product is probably decent. Who’s going to put it in? Both could work fine but you need to make sure you’ve got someone who nows how to properly and professionally install them first.

Do you know how any of these units will fare in coastal climate conditions in the long term? With this harsh corrosive envoronment, I am concerned about the longevity of the system considering the investment.

Thelma, Good question. Salt air and winds are pretty treacherous on almost any exposed material or machine containing electronics. I know LG boasts a "white gold fin" technology that is supposed to make it more durable against erosion. LG coats the aluminum on some (or all) of their condensers. Other brands may have something similar in use. I’ve also heard there are third party coatings that you can be applied to the mini split (or conventional system) that will slow the speed of deterioration. Could also look into protecting the unit via shelter (be careful with that idea though need someone with decent wherewithall to do that correctly). Good luck!

!’m having difficulty in finding a multi-zone mini split capable of setting the indoor (cooling) temperature to 16 C (61 F). Many systems only seem to go down to 19.4 C, unless one gets into more expensive systems (e.g., Mitsubishi City-Multi S system). Help, please.


What is your desired use for the system? size of space? At 61 deg F you’re getting outside the range of air conditioning and into the range of refrigeration. You may need to look into refrigeration systems NOT mini splits.

I had a Sanyo unit installed 8 years ago that had two units inside and the compressor outside. I have had problems with the system over the years and then last year the main circuit board went out on the outside unit and cost me $1500. The system started giving me problems a couple of weeks ago and now the circuit board went out again after less than a year. I am considering replacing the system with a Mitsubishi. Are Mitsubishi more reliable than Sanyo? Can the inside units still be used (the Sanyo) or do I need to buy a complete new system? Also, should I only expect to get 8 years out od a mini split system?

Sanyo went out of business 2 years ago and was bought by panasonic. thats why the board was so expensive

Fujtsu RLS3h at 14 HSPF? How did you miss that. Better than the Daikin as 12.5 HSPF

Larry, great note BUT this article is on midline products from each brand NOT their very "best". Guess we’ll have to come out with another article to compare the best from each.

Now if did compare the "best" from each brand you’d find that YES the Fujitsu does have the highest HSPF at 13.8 in a 12k BTU model compared to Daikin’s LV Series with a 12.5 and 12 HSPF from LG’s Artcool.

I have in the 2 bdr apartment in NY , deciding between Fujitsu and Mitsubishi. Called for estimation they offered Fujitsu 24000BTU AOU24RLXFZH (with 2 handlers) and Fujitsu 18000BTU AOU18RLXFZH (with 2 handlers) . Which brand should I do with it ? thank you

I’ve had a Fujitsu 18RLXS since 2010. It replaced a 2 ton thru the wall unit and with the inverter (freq drive), it dropped my electric bills $40 a month. It is located to cool the upper rooms in a 48′ raised ranch and it turns the place into a walk-in refrigerator when set at 76 degrees on a 90 degree summer day with 70% RH. I don’t clean the particle filter as frequently as I should and I have never replaced the two small boutique deodorizing filters. I paid $3100 for it, installed and qualified for a $1500 tax credit in 2010. The unit actually paid for itself, literally. I’ve never run the heat pump, so I cant comment about winter use. Was recently in Israel and Mitsubishi is clearly the band of choice in Tel Aviv and Jerusalem where everyone has a mini split. I dont know if there is a better brand than Fujitsu, but it is the best appliance decision I ever made.

We are looking to install a mini split system in our upstairs bedroom and bonus room. First guy that came out said he works with ‘Sea Breeze’ units and recommend them. Can’t find much online about them, makes me wary. Anyone know anything about these?.

I am torn…
I live in Saint Louis where it is extremely hot and humid during the summer, but can also get very cold in the winter. Should I opt for the cold performance of the Mitsubishi, or the hot performance of the Daikin?
With the Daikin, I would likely need supplemental baseboard heat as an emergency backup for those very cold days/nights. With the Mitsubishi probably not. But probably isn’t very reassuring when you’re talking about your home and how warm it is in the dead of winter!
Thanks for any guidance,
PS – this would be a 2.5 or 3 ton one condenser, four evaporator system

I live in Florida so we always need AC. I feel like I am in a nightmare. I had my whole house remodeled and chose Daikin Split System (the units that go in the ceiling- similar to commercial). I was so excited because I know they have split systems in Europe for a long time and love them. My system was installed in 2011. From the beginning I kept thinking this is not cooling properly so I kept calling the installer to check it. One unit backed up and was not draining. I even had a Daikin Rep come out and told installer to make some adjustments. I would have system error codes on and off. I could go on and on…then last year, I came home one evening and my house was "HOT" no Air. It was a depressing. Daikin recommended I have this guy come down from Orlando to evaluate the system. After several hours of system checks he informed me that there was no freon in the system. He of course had to go back to Orlando and said let’s see if it happens again then there is a leak. Well exactly 4 months later BOOM, no AC again. Now I didn’t want to have to pay someone to come from Orlando (travel time $85/hr x 4 hours without any work yet) so I called Daikin to find me someone more local…..that took 13 days. At this point I am thinking how can you sell systems and have no people to work on them. To date I have spent $5000 in service calls. Now, after all that money, they isolated the leak to one of my units (the one I had been complaining was making a hissing noise) had a small freon leak that got bigger; it was never diagnosed properly. So the one unit needs to be replaced. The company who found the leak (not the installer) is refusing to change the unit because they don’t want to get involved with this Daikin issue. I have talked to numerous Daikin people over the last 3 yrs and started saving all correspondence. I just keep getting empty promises and they have me going around in circles and guess what, it is off Warranty now!! My next step is Corporate in NY….Their Customer Service stinks and good luck finding appropriate people to service you. I would not recommend Daikin.

I live in Orlando, no corrosive air. On remodel on older home, I went with the Daikin 4MXS32 Multi-port with CTX Head Units. I’ve had very similar issues and spent over $2000 on labor to fix this unit (placed in service date 3-11-14). Finally a slow leak was uncovered in one of the evaporator coils. This was many months ordeal… no heat this last winter! I had to live with a space heater! I’ve gone to Florida Department of Ag & Consumer Services. Daikin had their counsel respond with an offer "technical service rep (aka: my HVAC service guy) perform a limited review and inspection of the installation and operation of the unit(s)". Wow… nice to know after the unit is operational, since I spent the money to fix it, they’ll come out and confirm it works!! Please purchase a extended warranty that cover LABOR!!!! Otherwise you will be eaten alive with LABOR charges. No part can be be replaced except by the approval of the Daikin tech phone support (HVAC guy has to call every issue into Daikin) and then the replacement part number is released, which will result in one or more additional service calls! LABOR Meter runs HARD with Daikin!!!!

I have a LG Artcool that does an excellent job, the problem is that almost every season change I find myself replacing thermistors. Is this just an LG problem or do they all have this problem. I have found that no one in this area of northeastern NC, or southeastern VA wants anything to do with the LG brand as the customer support is so bad. I’m thinking very strongly about replacing, but don’t want the same problem with a different manufacturer. Any help?

I live 4 blocks from the ocean (Neptune Bch, FL) and my Daikin was installed in 2006 by the previous owner. In May 2012, the fan mother board went out and I called both Daikin and the original installer who said "no warranty" so I paid $1400. Now again August 2015 the fan stopped working. I had a tech come out to say it was the fan mother board and "all comonents talk to each other" so it won’t turn on. I called the company who replaced it last time "Another $1400 – no warranty, only 1 year on labor" I was told. Are you kidding me?? I called another Daikin certified vendor and it was $2000. He said it sounds like Daikin is forcing consumers to go with a newer system. What a rip off. Does anyone else have this problem with the fan mother board?

Thats rough. Sorry for the difficulties. A few thoughts that may OR may not apply fully to your situation.

  1. A lot of what you’re experiencing could be related to the fact that you’re home is so close to the ocean. I’ve not checked Daikin’s standing on "salt air proximity" but many manufacturers do not warranty equipment operating in a more corrosive environment.

  2. The system is almost 10 years old. Most brands have seen big updates in their design, operation, and yes "how they talk together". Many parts from 9 years ago could be rare and yes expensive to change.

  3. Circuit boards can be very complex to swap out. I’ve spent in excess of 4 hours on a single control board before on a mini split. Not including drive time, buying parts etc. It can be very precarious.

Excelente trabajo.. Me ha servido mucho para recomendar en la Ciudad de México…

I live in Missouri and need supplemental HVAC on on a second floor with four bedrooms where the cooling capacity of the traditional HVAC system doesn’t provide sufficient comfort. The first floor heats and cools fantastically, but it appears the existing ductwork is the limiting factor for the second floor. I’ve narrowed down my choices to Daiken or Mitsubishi. There are four bedrooms off a long hall (one of which was finished after the construction of the house so that bedroom was never factored into the heating system design to begin with, in total about 950 sf. There is also a bathroom off the long hall connecting all the bedrooms in a row. I want to install an indoor unit in each bedroom. I thought about two outdoor units serving the four bedrooms (two zones for each outdoor unit), simply because of a bit of concern for one outdoor unit providing for the entire space (clearly, however, that costs more). But, I’ve come to think the manufacturers should know what they are doing with their systems relative to multi-zone units – is that a needless worry of mine?

Also, I’d like to install myself in terms of placing the bracket for the indoor unit (wall, not ceiling), cutting the hole for the condensate, supply/return refrigerant lines, installing the raceways for the pipes/control wires, placing the outdoor unit on pad, etc. With a proper kit and practice, I’m confidant I can create good pipe flares even though I’ve never had to do that before. I’ve worked with plumbing, albeit, not high pressure plumbing (just ordinary water pressure service to a residence). I understand the concern about the flare being created perfectly (large enough flare but not too large, removing burs and preventing introduction of foreign matter into lines); I understand the concern for preventing refrig pipe kink, for sloping condensate lines, for proper torquing of fitting connections, etc. I would plan to have a contractor perform the pressure test, performing evacuation of lines, provide additional charging of the system if the lines are past limits for pre-charged capability, removing refrigerant if line length is less than recommended, hooking up high voltage service to code requirements.

Also, advice on need or inverted trap directly adjacent to condensing unit and an oil trap for more than 16′ of vertical rise would be much appreciated. Am I crazy to consider doing this myself?

I noticed from the spec sheets for the Mitsubishi M-Series and Daikin LV Series, 15,000 Btu/h unit, that moisture removal for M is less than half that taken out of the air by Daikin, 0.33 & 0.8 gal/h respectively. Living with humid summers this performance lag in the M product is a detractor, that is as a first time buyer/user of a/c equipment. Is this truly a concern, will the M not dry the air as effectively as the Darkin and end in a ‘clammier’ conditioned space?

great question. I’m not sure if we should worry too much about the moisture removal rate. but I suppose this goes to climate. The goal is to be somewhere between 40-50% RH for the sake of room comfort. Going below that is not necessary. ie you want moisture removal but don’t need to overshoot removing water from the air.

Two years ago, I bought a 24,000 Btu 18 Seer Fujitsu and it was the best decision I made when remodeling my home. I live a few miles south of Boston, MA and have oil heating my home. I use the heating more than the AC.

It cost $3,000 for the unit and the install. I think the unit has probably paid for itself in two years. I live in a 1700 sq ft ranch home with an open floor plan and the unit has no problem heating and cooling the home. In the dead of winter, when it is 0 degrees, I will have to turn on the oil to supplement the Fujitsu.

I highly recommend these systems to anyone thinking about investing in a unit. This is an investment. You will save money and have a cool house in the summer and a warm house in the winter for a fraction of the cost.

I am just surprised at some of the prices that people report on here for unit+installation. I have had 2 estimates recently, a 4-head Mitsu installed for $13k, or a 2-head Mitsu installed for $11k. Also, when I make the purchase, I will be making sure there is an extended labor warranty…. the horror stories get pretty expensive.

TJ | Reply

We would NOT recommend Daikin split system air conditioners for server or telecom rooms. While the manual indicates that these units will automatically resume operation after a power outage, the manufacturer neglected to fully qualify this; According to Daikin tech support, they will do so if the outage is up to about ONE HOUR, otherwise, they must be restarted MANUALLY. This would probably not be as critical an issue for residential use, but it is a glaring flaw when installed in equipment rooms, particularly those in remote locations. Units from many other manufacturers do NOT have this limitation.

I am considering a unit for my basement, which can get hot in the summer (it’s a walk out basement) and it gets very humid. Our local HVAC company recommended a Mitsubishi unit. But I wonder if I’m going to still need to run a dehumidifier for times where it’s not very hot but the basement still gets humid. Would the LG be a better choice – that appears to have a dehumidify mode??

All the window air conditioners in our latest tests do an excellent job of cooling and come with such convenient features as a digital display, a built-in timer, a remote control, or touchpad controls. But some models are noisy and others struggled to cool during brownouts. Find out which to buy for the space you need to cool.

• Bedrooms – 9000 Btu each
• Dining Area – 18000 Btu
What brand for a new installation of ductless multi split units air conditioning system in can you recommend? Thank you for your help.



Go with Daikin or Mitsubishi
they are the most reliable systems
I installed thousand of Daikin and never have to replace single compressor
make sure the installation done right, hire only pro installer, go to Daikin site or Mitsubishi site and search for contractor by entering you zip cod.

I have a small drive thru coffee shop in San Diego Ca. It is apx 96 square feet. I need both heat and air. Would run cooling almost 24/7 for at least 6 months of the year. Temp inside the shack can get up to apx 90+ degrees at night in summer when shop is closed, due to refrigeration equipment. Ive been looking at the Daikin LV series, 12 BTU, 20 SEER system. Was hoping you could help me out with a couple of questions:
1) Is a 12 BTU enough…or to much?
2) Is it a good/smart idea to purchase the equipment from an online company and have a professional install? I have several customers that are installers for the top Daikin, Mitsubitshi and Fuitsu installers in the area. They are installers that could do the install, as a side job. thus, not going thru the certified dealer. As the cost doubles.

I love when people recommend Mitsubishi when I see, time and again, that their logic board is located in a space where lizards like to dwell in warmer climates like Florida, and the critters and their poop eventually fry the board. Guess what ISN’T covered in the parts warranty for that? The LOGIC BOARD. Dozens and dozens of complaints about this. If you’re going to review these things, how about dealing with the realities of humidity, critters, etc. Anything that can set someone back $500-$700 because it has nothing to defend against damage like that is not worth owning. I hear the Daikin does better. Yes?

I am in the process of getting quotes on a 9K heat pump mini-split. The company representing Home Depot submitted a quote that was $1600.00 higher than the current lowest bid. The low bidder even included a service contract on my total home unit. I was not impressed with the poor effort from Home Depot. The representatives were very nice, but the price was not competitive.

Daikin LV series comes standard with a 12 year parts and 12 compressor warranty not a 5-7. A 12 year labor warranty is offered as well (a little extra cost for the labor of course). 12 years of worry free operation…. I will deal with a couple of decibles!! OH and did I mention Daikin will be manufacturing there mini-splits in the USA starting next year! If you couldn’t tell I am a bit of an advocate for Daikin.

I live in Northern Minnesota where the temp. can get down to -50 F. The house is currently heated solely on electric baseboards. We have no ductwork and no ability to put ductwork in the house without completely destroying in. We have had 2 contractors out to the house and 1 says a mini-split will work (recommending Fujitsu) and the other says it won’t because they won’t give us enough range for heating. I realize that I may need to use the baseboards when the temps get really, really cold, but wondering if a minni-split would work 80% of the time or so and which one I should get. thank you!

Clarissa, Great question. Every major manufacturer lists their operating range (ie the temps they say they can work correctly). I’ve never seen this go below -5 F. As for -50 deg? No way. Most systems out there need operation above 5 degrees but again check with the manufacturer specs specific to the type of systems youre looking for. As long as you are above the "operating range" stated by the manufacturer the system will work. Many Multi Zone units only operate down to 5 degrees F.

not all mini split can operates at low ambient in heating, most mini split loose 30% capacity from 47 f and down to 17 F, others named hyper heat or enhanced heat can operates down to negative -15 f and you get 100% heating capacity at 5 f, when down to -15 F you will get around 70% heat. all hyper heat built-in with heat element in the condenser unit to prevent freezing. increasing heating efficiency is to build canopy on top of the condenser and two wall on the right and left of the seconder to prevent wind, also to install wind baffle to protect the fan, that will increase the heating efficiency.
The best reliable systems are Daikin and Mitsubishi, if they installed correctly you will not have a problems, look for Mitsubishi Hyper Heat or Daikin enchanted heating systems, or Daikin VRV IV S for Multi-zone, or ducted unit up to 5 ton.
(Daikin enhanced system require drain pan heater optional)

I asked a local A/C heat company for an estimate for a Mitsubishi system (one compressor and six indoor units one 18,000, one 9,000 and four 6000’s) He is pushing a Lennox system to accomplish this, with all units one step up, in case the temps fall below 10 degrees. Our house is in in New Jersey. It is rare temps fall below teens but two winters ago, temps did fall below 0 degrees.
I can’t find any independent reviews for Lennox. Does this seem like a good design? He said Mitsubishi system is a lot more expensive.

I’ve had a Lennox Mini Split (36K btu with 4 indoor units). I’ve had the mother board replaced twice and the compressor modified to handle dripping condensate directly onto the compressor. All I can say is don’t buy a Lennox, too many troubles.

if you do not mind me asking, I am in the market for a split ac and I am in New Jersey. I had A vendor come out a price quote from AJ Peri who only deals with Carrier products. The total was 23k, which I though was way to much. I have no knowledge about Carrier products and I am wondering why they are so expensive.

The quote was for two units

6k bedroom + 6k bedroom + 12K attic bedroom (unit one)

18k open downstairs + 6k bedroom

10 years warranty parts and labor is 23k too much, the unit had a 19 sers rating.

The data in this is skewed. As a contractor installing mini split systems we focus primarily on Fujitsu . So I am well versed in seer rating and warranty info. Fujitsu currently offers a 10 yr parts and warranty if installed by a licensed contractor and 12 year if that contractor is their elite lvl. The seer rating on their best 9, 12, and 15k models goes up to as high as 33 seer (best in the market currently). Sound is negligible and there is even a quiet mode. I would recommend doing some sound research if you are in the market as the technologies are ever changing in the mini split market. I would personally rank them Fujitsu, Mitsubishi, LG, and then Diakin. LG has some interesting picture frame style indoor evaporator units that take hiding your ac mech to a new level.


Layne Strider | Reply

The data doesn’t seem to be skewed just dated. Daikin has offered a 12 year parts and 12 year compressor warranty out of the box for quite some time now. And when installed by a licensed contractor you can get a extended service agreement (labor warranty) for 12 years at a extremely affordable price. Also Daikin is now made in the USA since they opened up a huge factory in Texas. I would most certainly not rank Daikin lower than Fujitsu or LG. Those brands maybe the most affordable but they certainly are not a superior product at technological or mechanical standpoint. Daikin also created their own exclusive swing inverter compressor. This change makes a huge difference in how quite and efficient the system operates. Most inverter compressors use a spring and a seal to create the compression cycle. Daikin has welded components together to eliminate the spring and the seal. Small change, big impact.

I love this article – thanks very much for posting and educating. A potential client just referred me to it. We generally recommend mini-splits for any client having a home less than around 3,500 sqft. When someone is building a super-energy efficient home like we do it’s crazy to install a traditional forced air system. And most clients do not even try to take advantage of the natural cooling effect of a concrete slab (of course with a stick frame home the benefits are not near as much as from a home made with our panels). Mini-splits are an off-shoot of the refrigeration industry, just as our wall panels and roof panels are. No one knows more about thermal control than the refrigeration industry – and they sure as hell aren’t stick-framing walk-in coolers.

I installed a 3 ton Daikin VRV-S for my main home and a 1 ton Mitsubishi ductless split with hyper heat in our granny unit. The Mitubishi is quieter and more efficient. The Daikin will not provide adequate heating below about 25 degrees and our home loses temperature when the ambient is in the teens. I have installed LG, Sanyo, Mitsubishi and Daikin systems. The VRV-S installed at my home is the only noisy one I have ever installed and I am extremely disappointed.

Daikin VRV -S is great system, gives you 100% heating at 5 F. and can operte down to -4 F. however the contractor need to know about VRV system before instillation.
All VRV system p recharged just for the condenser, once refrigerant pipes connected contractor must calculate all liquid lines and additional charge the system by programming the condenser, then he has to wait like 30 minutes to test the system by Sub-cooling premature. if the system charged correctly the indoor unit should blow hot air between 116-124 F. at 5 f. also VRV III-S can be programmed for higher heating and cooling performance. The new VRV IV-S can operate even better in heating at low outdoor ambient temperature.
Tip for cold area using heat pump. always install the condenser 2-3 ft from the ground. try to install the condenser on the side wall, build canopy on top of the condenser, use wind baffle to protect the fan for better heating. protect the condenser from strong wind on both side, this will improve your heating.

How critical is the maximum length of connections if you are willing to live with fewer than maximum zones operating at one time?

2/12/17 I have a Daikan split for my 22×22 shop with 12 foot ceilings. It completely iced up last winter when the heating plate that defrosts the machine went kaput. It got fixed and all was well after I worked for hours to get it free from all the ice and the technician replaced the heating device. This winter was the coldest since 1979 in north eastern Washington and it held up well until three weeks ago. It was no longer heating and my shop was in the 50’s. The technician came out last week and it reached 62 degrees but no higher. However, in the last three days it can only reach 50. The temp outside is 24 degrees. I called the technician again. I do not know if this is typical of Daikan or just this particular machine or this particular technician. He has not charged me for any of the service calls. I try to keep my shop in the high 60’s around 68. Air conditioning in the hottest parts of summer (100+ degrees) has been awesome. I am going to stick with Daikan and I am hopeful my technician will get to the bottom of this current problem.

sounds like you have a refrigerant leak that he cant seem to find. Daikin is a great unit, I’ve installed many of these systems with no issues in the past 5 years.

I’d love to hear about serviceability. I’m told that some units are difficult to work on due to assembly and difficulty to diagnose. Could you address these issues?

Has anyone tried using a Carrier brand mini split system? If so, do you have any feedback?

i installed a 12btu 1 ton senville mini split last year in my kitchen . i did the work myself with the help of my brother who licence in hvac but really was only for the warranrty. i just look at some youtube videos follow the company guide line for doing the installation and i didnt have any issues so far. when i hear people being charge 23k for some units i just wonder i should start installing them for 1/4 of that ridiculous prices…. im planing on buying 3 unit and 2 unit fijitsus for my living rm and other bedrooms. doing it myself is so freaking easy to do.

We are building for retirement in a VERY rural area in TN. We’ve been trying to decide between the mini split system and conventional – for our dome home. A few people have been out for estimates and none have called back with an actual cost. They don’t seem to know about mini split systems and certainly know much less about dome homes. I don’t know that there are licensed dealers for any of these good mini split brands anywhere near here (38311) – the brand name has never come up. After reading all these comments now I’m inclined to let these locals "go with what you know". If they did try to put in a system they are inexperienced with, that could just lead to trouble down the road.

1/2 or 3/4 dome? Makes a huge difference in your humidity levels. I have some experience with conventional systems and domes. Make SURE your contractor does a Manual J will take in the VOLUME of air you have. One we did in the south had a over-sized condenser to the air handler for humidity control. All the equipment mfgs produce to a price point. The installer is the key. Widen your search find another dome in the area go talk to them. It will be worth the trip.

The thing to remember is that a mini split doesn’t put fresh air into the home. People breath out a certain amount of water every day. Baths liberate moisture too. So you might want to be sure that you are going to get fresh air in the dome (which are very air tight) and moist air out. If you are running a bath fan there must be a way to get replacement air into the dome while you run it. And especially on the first few years you are going to want even more fresh air because the house components will be outgassing the chemicals they were manufactured with. You can also go with houseplants, like formaldahyde eating spider plants, etc. It’s still good to have fresh air.
I’m in a conventional 1970’s house which leaks plenty, in a very mild climate, and I’m still thinking of having three parts to my system. I have a gas boiler hydronics for heating (1970s). I want mini-split heat pumps for cooling and additional heating( for short intervals ( in bedrooms)) and I want a simple air circulator at night because in the summers we have cool night air which I can use to cool the large thermal mass of the house, before closing it up in the morning . Closing the house carries the house until 3 PM on a ninety degree summer day.
As I understand it, Tennessee has warmer summer nights so you can’t use night air for cooling. And the domes are so efficient that they don’t require a lot of heat or cooling. The Texas firm , Monolithic Dome Institute (www.monolithic.org) should have more information on heating and cooling domes. Best wishes.

All HVAC systems just circulate inside air. Standard HVAC systems have a Furnace for heat and an AC system for cooling. They have Supply and Return air ducts that just circulate inside air over the furnace for heat and over the A-coils for cooling. Older (less efficient) houses do not have many return ducts (like upstairs). I did have one at the top of the stairs of my house built in the late 1800, but it was not originally part of the house heated with coal. For air pressure to equalize there is usually a one inch gap at the bottom of the door to all rooms. A heat pump works under the same principle except the furnace does not kick on until the temperature get down into single digits. The outside condenser on a heat pump exchanges heat either out or in depending on the thermostat setting. All HVAC systems have a drain pan that collects condensation for water in the air. This is more predominant in the summer because the air naturally dries in the winter because of the furnace. There is usually a drain line built into the floor when the house is constructed. The drain line from the condensate pan runs down to the floor drain. On mini splits, there is a high and low pressure coolant line that runs from the mini split to the condenser outside. Because the mini split is usually mounted away from any drains, a drain line usually follows the coolant lines outside (usually pump assisted). There are control wires that also run out to the mini split and usually heat tap to prevent the drain line from freezing in the winter. More control wires may run to a thermostat on a mini split, although some are controlled from the font of the panel.

I only read this review because I saw one posted by Popular Mechanics earlier. They were promoting a “Pioneer” mini split. I had never heard of that brand. I’ve only installed Mitsubishi before. I never selected the brand I installed, the company I subcontracted to did. They did good work and only installed quality equipment (Trane) for standard HVAC or Heat Pumps.

I also am trying to decide on mini split system for my dome home in California, 1,500 sf. I need to get AC/heat.What did you end up getting. Salesmen says I should get one 35,000 Btu mini split since upstairs is just a loft. Any suggestions? He is trying to suggest Comfort Star or Fujitsu Thanks

Hi, We are considering a Fujitsu system vs. a Mitsubishi system and was wondering if the data for this article is still relevant? How do Fujitsu/Mitsubishi compare now?

Thank You,

Hi, my horrible contractor said he is only allowed to install a haier or daikin system? Which of those two are better. We really want the quietest unit and that will guide us to making a decision.

jay | Reply

Daikin by far. Daikin is a quality unit made in the USA. I highly recommend Daikin over any other mini split systems. I just installed two 1 ton heat pump units in my house and you cant even hear them run. VERY efficient.

Great article! very informative and to the point.

We are looking into getting a mini split system to replace our current heating source in our home and are wondering how well they work at warming a home. We are in South Central KS in an older home that is pretty poorly insulated so in the winters when the wind is blowing (which is pretty much all the time in KS) the average temps are in the mid to low teens and can get down to single digits. Any opinions on how well this would work for our home, brand that would be best, how many years it would last, etc? We have an A/C that works well so am not as worried about making sure the mini split would work for cooling since we can always back it up with our A/C unit.

The coil on my Daikin installed 2.5 years ago was leaking. Was so hard to find the leak because leak detector was placed on the fan outside with no alarm. Filled it twice, then second time was on and I could hear the refrigerant was escaping from the inside of the unit. I really thought I would be covered under warranty but I guess not. My the supply house where my friend the contractor got the unit from gave a brand new one to him for $800 not bad for a $2800 unit. Not bad but not happy that a part that seemed to be a really main component of the unit would leak. The units are great when they work. Might have been my mistake not putting a roof on it in the northeast. Should this part been fully covered ? Seemed like my friend could have gotten the part for less BUT then Daikin would of reimburse his hours, but taking the whole machine apart in 80 degree weather and waiting for it, not cool. Anyways just beware that if something breaks the process is not real clear.

are the number of btus divided between a triple split? For instance 1 area 250 2nd 200 and 3rd 450 in essence does the unit or outside condenser need to be then for a total of 900 btu or are each wall unit designed to meet each room

how much louder is the Daikin compared to the Mitsubishi? I have loud in wall A/C units right now. Is the Daikin as loud as those?

Paul | Reply

Amy, same question I have Daikin (45 db) is twice as loud as Mitusbishi (22db), but I have a much better Daikin price. The quietest dishwasher is 38 (db). A lawnmower is 90 (db). They say it is hard to have a conversation in a room at 60 (db). My dehumidifier, among the quietest, runs at 56 (db). I’m thinking now the Daikin, although not near as quiet as the Mitsubishi, is still quiet under most circumstances. I think you can assume you will hear it when it is on.

I’ve had mini splits for almost three years–fujitsu. I am very disappointed as there has not been a single summer since installation where there has not been a major problem–with either the indoor or outdoor units–requiring weeks to diagnose and repair. My largest issue is maintenance and I invite all suggestions. As instructed, I clean the filters on the indoor units every six weeks. However, it’s not the coils or the filters that get particularly dirty–it’s the infamous blower wheel and pan (dust, fuzz, mold-I hope not). In addition to making me sick (sinuses), I am rather certain that in addition to a decrement in cooling, the blower wheel will soon go off balance due to all the filth. This is not something that was ever mentioned when these were presented to me as virtually maintence free state of the art cooling systems. While my installer will take apart the units and clean the blower wheel, the cost is prohibitive (I have 6 indoor units) and it doesn’t seem that residential owners do this????? I don’t get it. Routine maintence seems to be cleaning the filters (duh). In my research, I have found a bib kit, pump spray and cleaning/mold remediation kit. Does anyone else know what to do. I am not a contractor, just a home owner who is pretty handy but not up to taking these apart.

I’ve had a bunch of different minisplits installed in small server rooms I manage (mostly Daiken, Mitsubishi) and coincidentally I have one Fujitsu 2 ton cool-only unit in a server room. Same exact problem — it starts to emit a wet smell along with black flecks and the blower is coated in crud. 3 different HVAC companies didn’t know what to do so I bought a bib kit and a coiljet for almost $750. A few times a year I put the big kit on and blow out all the junk with the coiljet.

I only clean the indoor filters once a year because it doesn’t get dirty and doesn’t make any difference in how long it takes to build up crud on the blower wheel.

I have AOU36RLXFZH multi unit split system. I had installed last year. I have ON through the winter and I have a problem at the end of the defrost cycle the indoor units blow a cold air for a couple of minutes at low speed. I contacted them and they don’t have an explanation why this happen and they don’t consider is a defective.
The indoor fan should be off completely during the defrost cycle.

Rick | Reply

Good Afternoon Mike what you are describing is called cold air prevention. In this mode the vanes raise up to a straight forward position and the fan runs very low, once the coil temp rises to approx. 120 degrees F the vanes will drop down and the fan ramps up. This is normal operation. Hope this helps be well.

this article was one of the most educated in days of my research i do on HVAC. i just need a few more opinions and ill make my final decision.. i live in townhouse in San Diego,CA space is approx. 1400 sq feet. we have living room, open concept kitchen with dining room on main floor and 3 bedrooms in 2nd floor. Weather here in SD like we all know is great but winters sometimes get little cold with temp dropping to 45 for weeks, summers we have nice and worm when accusingly temp high 90+ with humidly. We looking for unit that will keep us nice and cool in summer and warm up a bit in winter.. I’m almost sure that i would like to go with Mitsubishi since that the most quiet unit. could any of you specialist suggest model and system for my place.. Thank You..

My friend and neighbor works for LG so it looks like I’m going with LG in my house this year. There will be no more stupid window units in and out and I don’t care about slight differences in efficiency. I will install the system myself including all wiring and refrigerant charging. I will then post reviews as to it’s heating and air conditioning abilities. They all seem to boast about temperature efficiency but that is a condition to condition subjective comparison. You put any heating or air conditioning heat pump on a north wall versus a south wall and two units of the same make and model will perform differently. Braging rights should go to the makers who have longevity, product support and God forbid parts availability ten years or more up the road.

Never again will I purchase, nor can I recommend an LG mini-split based solely on their customer service. Our mini-split stopped working in August. While the parts are under warranty, the labor is not. The tech spent 4 hours during 3 visits on HOLD with LG for them to diagnose the problem. We received the bill yesterday and we were billed $440 for the tech to sit on hold. This isn’t a new problem, according to the tech, and the repair company will not be accepting any jobs where the unit is an LG anymore. We are going to be installing a multi-split in our bedrooms upstairs and a mini-split in the downstairs of our split-level house. Based on the matrix above, Mitsubishi is the winner for us.
