I am about to install 2 x 9000 btu split air con units in our renovated house. Small rooms so I reckon I have sized them correctly, after much searching through TV topics. I now need to decide which make/model to buy. My primary concerns are that the units will run quiet.  

Cost is also a factor, but I don't want a cheap one which annoys me. Does anyone have an idea of what I should expect to pay?

Is it better to get them from one of the major electric shops and get their version of free installation(???) or look for a dedicated AC shop? Reason I ask is that we are pretty far from the nearest city (Kaempheng Phet) and haven't seen any AC shops.

From another thread.

Not cheap but recommended as the best :-
    Daikin inverter are really quiet, recommended, no clicking, fit and forget.

I bought one of these lst time :-
One of the bedrooms we bought a cheap little Mr Slim Mitsubishi that is very quiet, impressed for the price.

Stuck a couple of Daikins in and quite peased with them. Not inverters though

How much were they? We have two rooms that need A/C but won't be occupied often, non-inverters will do the job nicely

apologies for hijacking this thread

I am looking for a unit that will work with just the fan running?

I don't think I've come across a unit that does NOT have fan only operation, certainly the Daikin in our lounge and the Samsung in the bedroom do.

I've installed 2 of the Mitsubichi "Mr. Slim" (9000 BTU) at different locations - as I recall about 17-18K baht installed.  This one is great for small to medium sized room.  Keeps the temp, very little noise, and I think efficient energy usage.  There are several options for cooling, vein circulation, and fan only.  It's a model that is only made in Thailand, but a good one in my opinion.

Actually installed 2 different sizes, one 9000 and one 12000. Total including installation was 17000b and 21000b. Mind you, 50 km from town and 3 guys for most of the day. Funnily enough, the firm who installed them are called Saijo Denki here in Kampheng Phet. I think installation was about 3000 each. Saw the same unit sin Big C in Nakhon Sawan yesterday, both were more expensive to buy without installation

Our samsung air-con in our bedroom has four setting, one seems to be fan only, when the room is cool enough I just remote switch to it and the compresser doesn't activate, it has 3 fan speeds as well.

My advice is to find a reputable AC shop near where you live and ask them what they recommend; they'll be the ones you call to clean, repair and maintain the unit in the future so it makes sense. I've had awful experiences with Thai 'electricians' who aren't familiar with the type of unit they are installing or cleaning - when I bought the unit from an electrical outlet they just subcontracted out the work.

AC inverter units may be an expense that you don't need as others have mentioned and any reliable unit will do...I had a Samsung for about 8 years in the bedroom and it finally gave up the ghost and I replaced it with a Hitachi with the same rating...not popular brands but they will do and not too expensive...

I just use it for when I sleep and it keeps the bedroom nice and cozy (27oC) for curling up with a duvet...not much in the way of features, just 'cold', 'dehumidify' and 'fan' settings and also has a timer...cheapest unit I've seen for the duty and about thb900 per month to run, less if you average over the year...

if yer running full blast all day then maybe an inverter unit is the way to go...

There are several shop's in K.P.P that will do the job for you + Big C and Makro all have a fitting service some included in the price so go check around. Give them the room size and they will tell you what size you will need. Don't Guess. To give you an Idea I have two of my bedroom's with air both about 4 x 4 mt floor size One fitted with a Saijo Denki 11.75 btu and the other a Panasonic same size. Both are very quiet will work fan only several speed's, the Panasonic is far the best within 10 Min: of turning it on the room is ice cold. Not to say the S/Denki is bad just dose the job slower. I live in K.P.P. if you would like to see them in operation send me a PM and I will give you direction's on how to get to my place.

Actually tutsi, it's the other way round. If you are running flat out mostly then the inverter has no to very slight advantage over a regular unit. Inverters come into their own when not being asked for full output because they can reduce their output rather than just be on or off.

Fred, I got mine fitted by Kampeng Phet Refrigeration, aka Saijo Denki. 3 young lads arrived and my only complaint was when the electrician was seen twisting wires together and taping them. When I stopped him, he said he had no proper connectors and no one else had complained before. He went off to the local shop, about 150 yards for some 5 Amp connector strip, then tried to charge me 150 baht for this "extra". He ended up with bugger all as I threatened to call his boss. We later asked the shopkeeper how much she charged him and she said 15 baht

Yep know the shop got my two S/Denki from them, have found them to be very good they even phoned me when the first free service was due. The Panasonic I got from another shop that was closing down and they were selling off everything at half price no problem with service as the S/Denki place service's all type's of air con. Enjoy just the right time to get them before the hot stuff kick's in.

Bought Mitsubishi inverters on professional insider advise on reliability issues - unbelievably quiet at the inside evap unit and even at the condensing unit outside, a huge benefit to finicky me.

[bbradsby]

Does anybody know if these typical units are plug & play, fully-charged and with pressurized lines and fittings that don't open till tightened down? I cant find any info on it, but assume they are pre-charged from the factory to make them idiot-proof. If they are as I assume, anybody reasonably handy with tools could install one.

does that mean theyre pre-pressurized... and I can hang it, connect the fittings, not charge it with refrigerant, connect 220v, and crank it up?

Noooooooo, same fitting as any other unit but they use 30% less energy than the regular units in running costs and are sooooo quiet. .

let's get the facts:

in certain cases which are optimal for inverters they might use up to 30% less energy. in many cases they don't save a single Baht of energy. the indoor unit is not quieter than a conventional unit running at the same fan speed and that the outdoor unit is quieter when there's no demand for rated cooling capacity is rather irrelevant.

whaaa? I thought that the whole idea of an inverter AC unit is about maintaining the selected temperature (and running 'full blast' inverter operation to do so) and modulating the continuous operation/speed of the unit (ie, while running at 'full blast' with modulated compressor operation) to achieve it, ie, no on-off compressor operation...so that if one wanted to cool down a room for sleeping a simple (set point controlled) on-off arrangement would do?

meanwhile, tutsi languishes in his inefficient, mideaval dungeon, dreaming about inverters...

sounds like I wanted to say 'full blast inverter operation' so as not to imply 'full blast AC compressor operation'...just a clarification; I ain't trying to cross Crossy...
