My house is approx 260metres square so they estimate wih 2700high ceiling you should have 150 watts per metre square. This equates to 39000 was or a 39 kilowatt system. Yet the builder supplied us with a 14kw system 3 zones and advised only 2 zones are to be used at any one time even though f we want we can run 3 zones. The other stupid thing is the installer has done the family room as our big open area whereas they could have change dit around and had one zone cool a small room with a door on it instead they now have one vent to cool a massive area or I can turn on another zone to cool the same area. how dumb Re: Actron ducted ac efficiency 8Jan 09, 2018 9:34 pm 6banga Interesting I found a formula on what size a/c one should purchase to adequately cool a home.

In addition, there are rooms which you do not necessarily have to cool (e.g. garage, storage, etc.). Also, it is highly unlikely would need to cool all the bedrooms as well as living spaces at once.
