Thread: Would these be any good ?

Assuming that they are the 2 part unit with a flexible refrigerant pipe and a box that you sit outside the window. They do work, but are much less efficient than a wall mounted box or a split system. Personally I've not found them to be particularly god value for money, but if you have a single small room to cool they may be ok.

Over the years a few of my clients have used them in control rooms. They work but they are a lot noisier than the wall mounted units and they need a duct for the hot air that comes out the back to get out of the room. So usually leave a window open and run the duct thru that with a bit of board to cover the bit of open window or drill a 300mm hole thru the wall.
Every where I've seen them they usually get replaced by wall mount units in a few years.

We had them up in the dongers at the mines (Pt Hedland) b4 the rail camps became active. They worked ok but they are very noisy! Not something you'd have in a living room or bedroom if you want to watch TV or sleep! As said before, you have to have a large duct expelling the hot air out of the window. There'll also be a small water drain pipe that needs to go out too!

Okay thanks.
I will give them a miss.
Like to see one of the advertised ones running tho.

You might be better off with something like this Robert.

That is, if the room that you want to use it in has an externally opening window. I've used similar to this before and they work well in a reasonably small room. Price is not much more than the two that you were looking at.
