I just moved into a new place, and there are no air conditioners installed. I only want to put 1 unit in 1 room, and there is already a small hole in the wall with a line running outside but I was told it would cost 2,500 to install a wall unit.

This seems a little high, is this the regular price?

I would avoid it if I could and just get a "transportable" air-con unit, but all the windows (and their screens) in the room open outward, like a door, rather than sliding up/down, left/right. So, I don't see how I can put the exhaust hose in the window.

The new movable air cons do not require an exhaust. I have seen some for around THB 20.000 onwards at Power Buy, Home Pro, Home works. The all had no need for an exhaust and could be easily moved. Size was about 1x0.45x0.30m. They had different units available for different room sizes. Did not buy one yet as it was too cool the last few weeks but will as soon as it us getting warmer again. In regards to the installation, sounds about right but some dealers will include the installation in the selling price. Maybe you need to visit one or two mor shops.

Thanks for the response

Do you have some examples? I believe I was looking at this one today, and it needed an exhaust hose. I am trying to stay around this price range:

Price seems reasonable.

Hey Tobias, I just called about one unit and the guy says that the units that "claim" they don't need an outside exhaust are wrong. The guy used the word "misnomer." Do you think this is right? He is saying they all need an outside exhaust.

You might check with an actual owner of those "portable units". They can be VERY noisy. You might also check around on a/c units with different shops. A properly installed quiet, energy efficient a/c unit will make life more comfortable, and might save you on the electric bill. If you deal with the right independent shop, you can obtain in writing the price to install and remove the a/c unit from a rental. In my observation, good a/c installers are worth the money and MOST landlords are cool when you move out and do some sort of wall patch. Some of the portable a/c units are SO LOUD you could hardly sleep in the same room or hardly watch TV in the same room.

price sounds right. Because they also need to fill it with gas and the gas costs.

portable units need to be exhausted outside other wise all the heat that is removed from the room will be re-introduced back in to the room

they have a large flexible hose that needs to exhaust the heat outside, through a hole in the wall or a window opening.

2,500 is reasonable. I have 2 of my own AC's that i take with me when i move houses. I always use the same company and they give me 2 services a year included. You must service them every 6 months or your electric bill will rise and rise and rise because the outside unit cant breath and vent properly.

There are some "portable air conditioners" that rely on ice water you pour in a reservoir which then acts like a coolant. Those would not require an exhaust vent, but I imagine it'd be a pain in the butt to keep emptying the melted ice/water and refilling it, no?

Every place I've priced air cons, they always included free installation, within a reasonable delivery distance.

Siam TV do it for free.

And their air-con prices are pretty keen too.

Useless in a high humidity environment like Thailand, are called evaporators

We purchased an lg split system from Tesco. Free installation or was at least included in the sale price for 17k baht.

The ones I referred to are not evaporators or swamp coolers. In those, the cold water is misted into the air flow and when it evaporates, it reduces the air temp. And as you say, not very effective in high humidity. Very effective in the Nevada desert, though.

The ones I tried to describe use chilled water in tubes and the air blows over the tubes -- like instead of Freon flowing through evaporator coils it's ice water. Until the ice melts, that is. So, you need to keep draining the water tank and refreshing it with new ice.
