My experience of evaporative is that it does not work. It's really just a glorified fan and is not really airconditioning.

Get reverse cycle instead.

They only work in dry climates.

If it's a humid heat they make it worse.

It does work ok, but not very well when it's very humid [it is cheap to run though]. If I was putting a/c in for the first time, I'd get a reverse-cycle.

If it's a new build, consider putting a core in the roof that will duct heating/cooling all over the house.

I was going to say the same, we had evaporative in our new build (mainly because it was a free offer!) and it was pretty pants once the temp went right up and the humidity started....

Agree. Ducted for a new build. Split systems for an existing house.

Reverse cycle is expensive to install and operate - and it's not very efficient.

It works well though.

Evaporative is cheap for a reason.

We're going the evaporative way. We don't have tons of money to spend and also don't want high running costs.

Depends where you live. If you live in Mildura Vic for instance evaporative is fine as its very hot and very dry. If you lived in Brisbane then it would be a disaster because its so humid and evaporative is humid too.

Ok here's my 2c worth:

We have a ducted Cool Breeze system and on the whole it works very well. Even last Boxing Day when Perth reached 44.6c we were cool inside the house as it was too hot to eat outside. Humid days do affect its ability to cool but what we found is if you know its going be humid start the system early in the day and it will keep cooling.

Evap is a very simple system which mainly consists of a large fan and a water pump to keep the Celdek pads soaking wet. For cooling you cannot beat a proper air con system but they chew electric big time. Our system chews about 900w an hour as opposed to the 17kw's that our friends system pulls.

There are pro's and con's for either system. Do a google search for more detailed info.

The kW figure most often quoted for AC systems is that for the cooling or heating capacity not the electrical stuff... 17kW would get you a pair of 25kW Daikin ducted systems which would cool a very substantial house indeed...

Very true mate. Its a huge house with two large chiller units outside. They pull that much juice that they only put it on when they have to !

Thanks for your reply. The is currently a good deal for Cool Breeze on so we're thinking of going that way.

Try to get a self cleaning / emptying cooler, this will stop the build up of
calcium scale on the batts. Brivis and Braemar ( I think ) have them.
Scale reduces the efficiency of the cooling over time
