Add-On Cooling Systems
This is a system that can be "added on" to an existing in-ceiling or under-floor ducted heating system, providing both air-conditioning and heating through the same ducting and outlets.
If your home already has a ducted heating system you may be able to utilise the existing ducting and outlets for an add-on cooling system.
The duct size required for add-on cooling is normally larger than for ducted heating. Also, add-on cooling requires additional fan capacity.
Unfortunately, some houses with existing heating ducting and units may need to be upgraded to suit.
It is advisable to have add-on cooling and/or provisions installed at the same time as your ducted heating system to be most cost effective solution.
