I've had my Samsung 21,000 BTU inverter unit for less than a year so I cant speak for long term use but so far, I am very satisfied with it. Very quiet, good air flow and very easy on power. My bills are less than half of what they were for an older unit. I'm cooling a 50 s/m open space, about 16 hours a day. No month more than B3000. I found Samsungs were much less expensive (B24,000 installed, Power Mall) than competing brands by more than 30%. Time will tell how good in the long run.

Daikin is no.1, thats all the do, worldwide....

some people differ from that recommendation, especially one who has 1½ dozen +1 unit installed and looks back at 9 years experience with Daikin.

verdict: Daikin? never again!

[stoneyboy]

Yes I'm more happier with all my Mitsubishi units that I've had over the years.

[peterrabbit]

I was told by friends in the industry (not selling to me) to only buy daikin or mitsubishi (the same unit as daikin) if you want an inverter. All the other makes have their problems. I brought Daikin and I am very happy with them, powerful and reliable.

[bangmai]

I was just about sold on an inverter, until I made a recent discovery. My condo neighbor put one in, and paid 28K total for a Samsung 18K BTU/inverter model. She says it is working great...but here is what I noticed. At about 5am, when I am reaching for a blanket to warm up, because I sleep with my windows open, I hear her unit turn on....so just how energy efficient could that be? So I think the return is going to depend on the user. While they do offer great savings on paper, if you are the type, who doesn't use it all the time, and prefers to take advantage of cooler air outside, it may not be worth it. I could have bought a 18K btu Carrier for 18K THB at Big C in May...Either way you will get a good warranty...five or ten years...but power fluctuations were mentioned, and whether or not they would weasel on a blown compressor as a result of a surge/spike I don't know. I owned on home in Vegas, and five in Arizona...so A/C issues come up a lot, and it's actually a life or death matter in some areas. At one point people were seeing who could buy the highest SEER unit. Builders grade was 12, which is the lower end here, but for about 70% more money, you could get an 18 SEER that would save you a lot of money....however, many discovered that once it is on and running, the usage is similar, the big savings came at start up, which occurred more frequently when the needle hovered around 75F outside, and you didn't really need it to begin with. For all around value/dependability/performance, I like Carrier and Panasonic...and York is pretty good too, but they seem to be about the same price as Carrier. I don't think you will get more than 5000 hours out of a mini-split compressor....that's actual run-time, so keep that in mind.

We went round and round - inverter or not. Spoke to many people in the business and decided we didn't need it. Some places try and sell them telling you all kinds of stuff. More commission for them.

We are however, very happy with our new inverter Samsung refrigerator.

Daikin or Mitsubishi.

an assumption out of thin air. the "mileage" (compressor run-time) of 5 out of my 19 installed units is an estimated ~40,000 hours each and i expect many more hours without compressor replacement.

my bitching in an earlier posting concerning the brand Daikin did not refer to any compressor failure but to fan bearings and electronics of inside units.

the author holds 70 HVAC related patents, if by chance you are from a country that knows what one is.

Automotive A/C compressors have a life of about 400 hours....Residential HVAC compressors will run a minimum of 4000, but will go 8-12000 if there are no internal failures. A mini-split is not as heavy duty as a true Residential system.

[fang37]

We purchased Mitsubishi. The size was determined by the retailer.

In fact, we rarely use them but better to have installed during construction phase.

i only hold one patent (which has expired years ago) and i care a flying fàrt about the rubbish² the author you cited claims and so do the compressors (until today) of all my aircon units... touch wood!

another article: "It is simply false to imply that an inverter driven compressor will operate more efficiently at maximum output than one with a synchronous motor. In fact, the inverter drive electronics themselves consume energy and impose a small efficiency penalty at maximum output. Further, the higher frequency drive also imposing larger hysteresis losses in the motor core reducing its efficiency by some amount. The inverter driven motor is in fact less efficient at maximum output than its synchronous motor counterpart."

In other words, if it is really hot outside, when you use it, you are spending more on the unit, to use more energy.

that is correct and i have mentioned this fact in various aircon threads several times. but facts don't count when Sven from north of the polar circle in Sweden, Ian from Scotland or Urs from Switzerland have for the first time in their life experienced aircondition in their homes in a tropical country and became after a short time eggsburts on inverter units.

then they claim

-very happy because very quiet,

-my electricity bill dropped by nearly 99%,

-my home is much cooler,

-sex with my partner is much better,

-my dogs are less salivating and stopped peeing in the living room,

-the lawn looks greener,

-the food and the beer have a better taste,

and last not least

-my brand of aircon is the very best! i have no experience with other brands.

But if it is so cool outside that it barely needs to run, then the inverter will use less than the standard, but at that point why not open a window, or turn on a fan?

And yes, the Germans/swedes etc. are big suckers for over engineered stuff that works great on paper, but completely lacks economics and practicality. I wouldn't trade my five year old Toyota for a brand new Audi. Apparently Angela's new state of the art airport is an Olympic size bust, but you can bet it has the best sgerman engineering.

I have two Mitsubichi inverted units one 9000 btu other 19000 btu with heat . The keep the place cool and my electric bill is much less than most of my friends that run non inverted untits . Plus they are very quiet ......

They're tearing out 55 miles of wires at the new Berlin Airport...fire alarms don't work right. They were going to hire 800 low paid human monitors to manually watch for fires, but decided just to delay a few more years.

anybody who drives a 5-year old Japanese car can neither afford a new Audi nor does he/she possess the qualification to judge German engineering

joke aside, the airport is not yet operational and won't be for at least another year or two.

Half my ancestors are German, I got a German name, and my dad looks like Rudolph Hess...is that german enough for you?

[bangmai]

Whatever brand you buy, buy an in inverter. One reason is that unless they are constantly running at maximum output, they will be cheaper to run.

However, more importantly they create a much more comfortable environment. Non-inverters are switching from off to maximum power every so often in an attempt to maintain constant temperature. In reality, they are only able to keep the temperature within about a 3-5 degree range. This is annoying because sometime you are too cold, sometimes too hot and the humidity goes up and down as well. An inverter AC does not suffer from this problem.

Also, if you are a light sleeper, you won't be woken up by the sound of the compressor powering up every few minutes.

Once you have owned one, you will never go back.

actually, you can set the differential, so it will come on at .5c above target, 1 or 1.5...to avoid the too hot, too cold problem...the higher differential will save you $$$, as it prevents short cycling. If your room is 5F above setting, and you aren't cooling an oven hot room; your system is &lt;deleted&gt;.

ok,thanks for answers,but at the end i still don't know inverter or not!saijo denki,ok?

Personally I don't think the inverter is necessary. Saijo Denki is a very good Thai brand. I have an industrial grade unit that has been going for many years now with no issues other than the swing motor no longer works (which I think my kid broke when he was little). Our people who service our A/C's told me Saijo Denki's are some of the most dependable on the market.

Having said that, I like our Daikin unit a lot.

absoeffinglutely pure refined rubbish!

p.s. and if you wake up because the outside unit starts you should have spent a few bucks more and built or rented a home with brick walls instead of plywood ones

i humbly apologise! with a dad that looks like Rudolf Hess you are indeed qualified to judge German engineering at any airport. therefore i'd be interested in your judgment of the airconditioning system of Frankfurt Airport, specifially Terminal C. what do you think about it? i always find it a little cold when i arrive in winter.

[bangmai]

The A/C was working fine, last time I was at the Frankfort airport in January 2014, especially out on the tarmac, where we had to deplane. The soap dispensers and plumbing were very impressive, though. You had to move your hands around and an automatic dispenser would put 3 ml of soap on your hand, then the water would come on with such high pressure that it would be washed off before you could put it to use. Lather, rinse, repeat....about four times.

I talked to some more a/c people yesterday. They were putting in a 18K BTU panasonic, with inverter. Thy seemed to indicate about 20K THB. No one else has mentioned the importance of getting a 410a system....I think with an R-22 system, you could find yourself getting extorted for refrigerant a few years down the road, if needed. It happened in the US after the new laws took effect. Some research shows that Toshiba and panasonic have a large market share of the actual compressors used in the splits...I don't know exactly which companies use them, but you might be surprised. Just like the main components of the old HP Laserjets were actually made by Cannon. I don't know why Mitsubishi gets so many favorable reviews here. Mine was worthless after 8 years. I just installed a new bathroom fan, and bought the Mitsu...it's amazing how thin the wires are...especially with copper being so cheap now...their cars have a poor reputationin the US..also known for electronic trouble, and poor resale value...and weren't they the creators of the single use bomber airplane?

[Naam]

instead of replying to all points mentioned in your chaotic posting i'll pick an interesting fact you mentioned. i claim that the statistical life expectancy of most retirees in Thailand is too low to experience a shortage of R22 as is the case in the United States and some countries of the European Union where refrigerant smugglers are minting money since several years.

by the way... buyers of aircons in Thailand are anyway s-krued in many cases by deliberate shoddy installations which require quite often a yearly "topping up" of the refrigerant. most of them (the buyers) have also no idea that a correct installed split system does not need any "topping up" during its whole lifetime.

[bangmai]

I saw this in a Mexican newspaper: no mention of inverter, and it hits 50c occasionally in Hermosillo.

Prices in THB would be 12,000 btu=9900 thb 18,000 btu=15,092 thb and 24,000 btu=18,761

There is clearly some profitability in these things.

dear Sir,

1 ton equals 12,000 btu and the price of $ 4,590 for a 3ton unit (36,000 btu) applies obviously to a central air "block unit" as shown on the right side of the ad and includes most probably installation of ducts as well as ceiling outlets.
