Hi all, I was hoping for some advice on whether installing a ducted evaporative cooling system is the way to go in comparison to other options such as split system cooling. Some background: I am currently doing a feasibility on building double-storey townhouses in Belmont (one of the suburbs of Geelong). I intend to keep all townhouses to rent out for the long term. Cost is a consideration in that I do not want to spend as much as for a ducted air-conditioning system, but I want to balance that with cooling effectiveness for the warmer months. I have read that evaporative cooling systems are not effective in the height of summer. Would it be worthwhile from a cost and cooling effectiveness perspective to install one split system for the ground floor and one for the upstairs versus a ducted evaporative cooling that will have a vent in living spaces and bedrooms? But I am also willing to consider ducted air-conditioning if the rental yield on the installation cost is high, eg. installation cost = $12,000 but delivers a $25/week higher rent. Are there any other solutions I may not have considered yet? Appreciate your thoughts! Eug.
