Choose the right unit for your needs
Do you need a system that is ‘cooling only’ or ‘reverse cycle (cooling and heating)’?
This will help you discount a lot of options. ‘Cooling only’ is cheaper, but only slightly. So, even if you have another form of heating, it’s worth considering a ‘reverse cycle’ unit as a back-up.
What is the ceiling height and floor area of the room to be air conditioned?
Obviously the size of the room has a big influence on the capacity of the unit you need, so measure the ceiling height and room width and depth.
Do you have ceiling insulation in your roof?
A room with no insulation will require more capacity to air condition than a room with properly installed insulation.
What aspects are the windows in your room facing (ie North, South, West, East)?
This will affect the natural temperature of the room and has a big influence on the type of air conditioning required.
What are the sizes of the windows in your room?
Knowing the size of the windows will help your choice, so measure their height and width.
