We have 400m2 living and we're in SE Melbourne. This is divided into two zones, upstairs and downstairs. We were told that for that much area to cool we should only run upstairs or downstairs not both together (Heating is no problem for both zones to be on). We've found in practice that we CAN run both zones and keep the house comfortably cool so I would think 23KW should be OK. Keep in mind your house orientation, shading of windows, insulation, etc will impact effectiveness of any system. Hi Ourlindrum52, Im in the process with a builder for a similar sized home and we are building in melb as well. We cant decide whether to put in evaporative cooling or add on cooling like yours? Have you found it useful in our summer to have the add on cooling and has it been costly to run? Thanks ![]() Re: Aircon advice please! 11Jul 31, 2012 2:55 pm We vowed not to get evap again after having it for almost 20 years in our last house. Mind you, we lived in Perth which has mostly dry summers, however....at most it will cool the house down to 10c less than the prevailing outside temperature, so if it's over 40c outside, its only slightly cooler but a lot more humid inside. So your tiled floor is sticky, your bench tops are sticky and try sitting on a leather couch then getting up again! You'd want to wax first. After moving to Melbourne, which gets hot but not as long and can get humid too, we thought refrigerated was the way to go. We've only had it since we moved in January but very happy with it. Apart from just cool air, it is cool and dry air so on those warm muggy days it's very comfortable. I can't really say how much more expensive it is to run because we've only had two power bills and they were both around the same. In winter my wife runs a small electric fan heater in the bathroom when it's cold. We found with the refrigerated we don't run that as often as we did with evap cooling. Possibly also because newer houses are better insulated and also being two storey, downstairs generally stays cooler. One other thing, some builders will not run evap cooling ducts to the ground floor of double storey homes. Not sure why but maybe because the double ducts (one for heating and one for cooling) take up too much space or require additional voids to cope. (Add-on refrigerated cooling uses the sane ducts as the heating.)

Our house is 298 square meters of living using 8 zones and 11 outlets. Looking at the calculations we can cool all sleeping zones or the living zones at any one time. Actron is the way to go if you can pony up the extra money to start with, as I'm sure you would get it back in energy savings and quality down the track. ![]() Re: Aircon advice please! 13Nov 12, 2013 12:01 am ![]() We are going Actron ESP+ 17kw 3 phase unit installed by Jeff Moritz Gas and Air for $16K.
