After air conditioning in Marsden Park? Jay's Air has been doing it since 1991. A typical two-storey 4-bedder here wants a 14 to 16kW zoned ducted system at $9,000 to $12,500. A 2.5kW split for one room runs $1,800 to $2,100. Fault-finding is $250 plus GST with the fix quoted first. 4.8 stars from 280+ reviews.
The question we hear most out here: why doesn't my brand-new house cool properly? Because the builder-grade system was priced into the package, not engineered for it. A 10kW unit on a 280-square-metre two-storey with western glass never had a chance. The fix is honest sizing - sometimes zoning changes, sometimes a bigger unit.
Dark roofs and open plans change the numbers
The estate spec of dark roof tiles, high ceilings and open-plan living adds serious heat load. Homes here regularly need a size up from what the floor area alone suggests - 14kW where an older suburb's 4-bedder takes 12.5. Zoning matters double on two storeys so the bedrooms upstairs aren't fighting the living areas downstairs all evening.
If you're building, rough in the air con before handover - pipe runs and circuits cost little during the build and plenty after. Run your plans through the sizing calculator and check the pricing guide before signing anything with the builder.
