We are building a new home in Melbourne (28sq single story) and have evaporative cooling included in the promotion package. The included cooling unit has 5 cooling points which will cover living area, dining area, play room and master bed room. We can upgrade the cooling unit to get extra cooling points in the other three bed rooms (cost $1,700) but are wondering if its worth the extra cost or the smaller unit will be able to keep the whole house (including the three bed rooms without cooling points) relatively cool
