My understanding as well.......maybe good for those in the boonies who don't have smooth power. My last trip to Homepro appliance center.....seems like most refrigerators and washers are inverters these days....and prices are as low as previous models that weren't inverters!

Good one maaka, didn't realize it was a bedroom game, but if that's the only place you have and AC unit on a hot evening then well and good, carry on.

My rooms are about the same size as yours and I have 10 x 9400 btu Samsung non inverted units and they have all performed marvellously for a year trouble free and whilst I'm sure the bigger inverted units are better I have to say mine do the job nicely and are very inexpensive.

the problem in los is that the shops always oversize the btu needed for a room ,i also look at the inverter like this,for the price of an inverter one i can buy 2 non inverters almost ,and as i said i have done the real test non inverter versus inverter type and the kw profit from inverter was not a lot more profitable as the non inverter , in real i mean , not on paper... but as long as you are happy ...and stay happy...;)

I've asked this before, if while your looking around I'm interested in getting a multi head unit, but they seem rare here in Udon. Multiheads in Australia usually have one main unit and 3, 5 or 8 slaves.
Kakariki

I was looking for the same sometime back, Diakin along with others have the units but Udon not have. They are an interesting concept and I may look further.
I imagine you would have to contact the main sales office in Bangkok. But I think it was home pro on the ring road??? the AC guy said he could get anything from Diakin if we want and order. I was only looking for ceiling cassette units at the time.
Make sure you get invertor to save long term money.
Is this what you mean

Inverter Air Conditioning
Inverter air conditioning is :-
•At least 30% - 50% cheaper to run as it consumes less power
•Far quicker to achieve desired temperature
•Much quieter
•No temperature fluctuations, maximising comfort level
•Lower starting current compared with non inverter air conditioning

So, in summary an inverter air conditioning can reduce your energy bill. It will be worth paying more for an inverter air conditioning if you use your air conditioning for:-

•all year round or regularly.
•used for heating

With energy costs now still rising there is no doubt this will save you money in the long run.

What is the difference between inverter and non inverter air conditioning units?
Non inverter or Fixed speed air conditioning deliver a fixed amount of power via a fixed speed. This means the compressor has to stop and start to maintain the desired room temperature.

Inverter air conditioning system, varies the speed of the compressors, delivering precise cooling or heating power as required.

How does Inverter Air Conditioning work?

The amount of cooling or heating required by an air conditioning unit varies depending on the outdoor temperature and the amount of heat in the room.

When the cooling or heating capacity needs to be increased, the compressor will operate at a high speed and will increase the amount of refrigerant flow.

Conversely, during moderate outside temperatures for example, when the cooling and heating capacity needs to be decreased, the compressor will operate at a low speed and will decrease the amount of refrigerant flow.

When the inverter air conditioning is switched on, the compressor operates at a high speed in order to cool or heat the room quickly. As the room temperature approaches the set temperature, the compressor slows down, maintaining a constant temperature and saving energy. Any sudden fluctuation in the room temperature, will be sensed and instantly adjusted to bring the room temperature back to the set temperature.

It will be worth investing in an inverter air conditioning if you use your air conditioning all year round especially for heating your room or you use your air conditioning regularly.
Basically what my HVAC mate said to me 5 years ago.

When people ( Expats ) whose expertise is in Air Con and Electrical Installation of these units , I go with their advice.

well i have made a change of mind to make the test if inverters are really cheaper , but most because the price was this time good , i have bought for our 2 bedrooms an LG 12.200btu/inverter for 14.500 baht all in , and the installation done perfect , no ugly drilled holes filled with wall putty after ...nice people ...also perfect drilling inside on tiled walls...

they have also made a quote for a bigger air con , 18.000btu/inverter/22.000 baht , 24.000btu/26.000 baht all in ...
if you are interested for any price call them 0862261992 mr sunan ...good luck ... ;)

Awesome deal... makes me wish I had waited. Then again, with the temperatures we've had off and on since Songkran, maybe not.

The dipshit that installed our system threw away the vibration isolation rubbers when he mounted the outside condenser unit on the angle brackets; a common enough short cut by these useless bloody 'artisans'. Usually it is because they don't have long enough bolts but looking at this bodge, that's no excuse as the bolts are easily three inch long.

Anyone know where I can get these around the Udon hardware traps? Otherwise I will drop by any aircon shop and see what they have.

Thanks!

Hmm, those rubber pads between unit and brackets? The guy I have used to install and clean, installed them and he supplied them, they did not come with units.

My other 2 units do not have them, and he did not do the install. Wanted something like them when installed. Even had company send people from Bangkok, because of vibration. They didn't even have them. After a few months the vibrations went away.

Don't know where to find, but if you can't find, can get his # from wife.

The condenser unit had them fitted as standard when he was about to mount it on the ground but somewhere between stopping that folly and hanging them on the brackets, they disappeared. As is usual in LOS, they tend to leave debris and junk behind them but I guess the vibration isolators all manage to end up in a pile of useful junk in the back of the truck.

Didn't have them at the home improvement stores on the north side or Global House (north) so Thai Watsadu and the new Global House manana.

Finally went with a Hitachi 12700 BTU non-inverter unit that they discounted heavily to bring it down to 15k baht installed (from 19.5k baht list). Installing manana so just one more night in the sweat box!

Measuring 101°F in the shade on the front patio right now.
OK! It's heating up and the kids bedroom needs a/c. Wishing to keep to the same brand (if only to hot-swap the remotes if and when), I looked at PowerBuy online and the cheapest (only) non-inverter Hitachi is ~15k including installation.

Anyone seen any other bargains around town? It will start heating up between now and March/April will be manic and waiting for a few days for an installer then so trying to beat that crowd.
