Browse Forums Heating, Cooling & Insulation 1 Jan 17, 2011 7:51 am Hi, Topic says it all really. I'm building a 2 story home at the moment. The house will have full ducted heating, but we said no thanks to the Evap cooling. I was just going to look at 3 or 4 split systems (or maybe a multi head system) but a mate said he had heard of people adding a unit that could use the existing ducts. Does anyone know of anything like that? Thanks, Milesy.

Generally the gas ducted unit has to have 'extra air' to allow for the increased airflow required for the cooling you will find manufacturers have standard and extra air (XA) models. The ductwork also needs to be upsized to facilitate the extra airflow required (cooling) but still doesn't sit right with me in relation to size compared to a ducted refrigerated system but in Vic, they don't seem to mind You get what you pay for! Re: Can I add an air conditioner to existing Heater vents? 4Jan 17, 2011 5:32 pm We had a split system added to our ducted heated after the build. We have had it now for four years and we are happy with it. As others have said we had the size of the ducts increased by the builder and a slightlly different heater unit fitted.
