Also, is anybody upgrading their heater to 5 star with zoning with bigger ducted points and future provision for Ice add on? Any sort of approx. cost will be highly appreciated. I am confused about heating & cooling system and for double storey what will be the recommended combination?
Many thanks.
Regards
Hi mib.ibn,
Not sure if anyone has reply.
I upgrade to 5 stars heating with one addition zoning. It cost me $2250 extra. Each additional zone is $1200-ish.
