Would Sir like his humid day 30 deg day with excess humidity and legionaries disease or just excess humidity?

Haha good old legionnaires not many people know about it but it's scary when you think about the potential consequences of it :/

Our aircon use is relativity low for where we live (the tropics)
Our house has large balcony's front and rear (east and west) so there is no direct sunlight on any windows or walls for more than an hour or so morning and afternoon.
We re-roofed and had some good insulation installed between the roof framing and the color-bond, which basically stops the heat from entering the roof space.
It is large open plan with the hallway having floor to ceiling louvers at each end acting as a breezeway.
as a consequence the house is relatively cool in the summer.

But if you are familiar with the tropics, aircon is a must, especially for sleeping.

I always thought that aircon was expensive to run, but I think that was due to the old conventional unit we had prior to our reno.
we have a summer here that can have oppressive heat.
The temps don't really make it up that high (in Australian standards) the average summer temp is only 31.5
its the humidity which is the killer.

The summer season (when we need aircon) runs from November to March.
During that 5 months we have our master bedroom aircon running aprox 10 hours every night
The next user would be the study, 2 or 3 hours a day, more in the weekends.
last would be the lounge/kitchen area, possibly only 2 or 3 times a week (mostly weekends) only for a couple of hours each time.
The splits we have are Fujitsu inverters and with the above usage are very cheep to run.
Our power bill for the summer period comes in at $150 to $200 higher than the winter period!

Natural airflow through the house can be a very important factor to keep the power bill down.

I also now know the modern inverter aircon are very efficient compared to the older conventional type.

I am not familiar with ducted cooling because most homes here are single story concrete block on slab.

But I would assume that with "zoning" you could cool only 1 or 2 rooms at a time , keeping the cost down.

Natural airflow was not something I really thought about until it was brought up by our draftsman/designer, but now realize it is a very important consideration in design.

So having said all that, I'm curious what people spend on their aircon.
