One of my aircons developed a behaviur

That always after the temperature is reached, the circulated air turns extremly humid (like in a garden house)

The only way to get arround that is to simply make sure the compressor never stops.

I had a company here cleaned it and check the pressure. But that did not help.

(Strangely in my old condo exactly that did fix it once and for all)

I called the company again, they came and checked, say everything fine

I should switch to dry-mode <deleted>?? Every 30 Min or what ???

Anyway, anyone has a clue what to do ?

Google 'air con dry mode' ... a mine of information there and might give you an insight to your problem. Also look at http://www.thaivisa.com/forum/topic/123827-air-conditioning-need-energy-efficient-advice/ and you may get the answer ... hope it helps.

No real idea, but a few thoughts.

Is the unit oversized for the room? An oversized aircon will cool the room rapidly but won't have chance to dry the air much whilst cooling.

Has the A/C behaved in the past? Particularly was it OK at this time last year, you could simply be feeling the effects of the local humidity.

You could try running in 'dry' mode for a couple of hours, you won't get the full cooling effect but it will knock the humidity down and make you feel more comfortable.

one reason could be that the drain pipe is partially blocked causing the accumulated condense water in the tray below the evaporator to drain very slowly and the rotating fan keeps on humidifying the air.

Good thought Naam, he says it was cleaned recently but who knows

it might have been cleaned but it was not necessarily checked whether the condensate tray drains fast enough. i had a similar problem with one of my units and realised it only by coincidence when passing because the fan on high speed sprayed even fine droplets from the outlets.

I did have to put one of my aircons on a "dry" mode because of that and still didn't work. It all went well after a gas refill and empty water condensation tray. worth checking both

I had the same tought, in my old condo i had the same problem, clean and refill did the job.

Thats why i called up the aircon company again (2 day later) they showed up, and say "everything fine"

I had to force them to check the coolant, they did then and again "everything fine".

somehow i had the impression that they not really wanted to go into that issue, since it was "cool".

I turned it on 2 hour before they came to make sure you can feel it, but they didnt.

Same blah lah about size and dry-mode.

My question "why it worked in the last 2 Years" stay unanswered.

The tray is clean, also the pipe is free (water gets out easy)

Still clueless.

The main problem seems that its kind of hard to explain the huminity problem in Thai.

Yes it did.

Flawless, the problem startet 2 months ago and getting worse since then.

In the bedroom i have exactly the same aircon (installed at the same time)

No problem at all.
