Retrofitting ducted air conditioning into an existing home

Most of our ducted work is retrofits into finished Sydney homes. We inspect your roof cavity, plan vent positions to minimise patching and painting, and tell you honestly if ducted, multi-head or split systems are the smarter spend. If the roof space is too tight, we quote the alternative rather than sell you the wrong system.

Frequently asked questions

How much does it cost to install ducted air conditioning in Sydney?

Fully installed packages run from $8,000 for a townhouse up to $15,000+ for a large two-storey home with full zoning. Your price is fixed in writing after a free on-site assessment — call 0426 499 802 to book one.

How quickly can you install ducted air conditioning?

We usually assess within 24–48 hours of your call and can typically install within one to two weeks, subject to equipment availability. The install itself takes one to two days for most Sydney homes.

Do you install ducted air conditioning across all of Sydney?

Yes — we install across the Hills district, Western Sydney, Parramatta, the north shore, inner west, eastern suburbs, the Sutherland Shire and the south west. Tell us your suburb and we will confirm the next available assessment.

Are you licensed and insured?

Yes. iNext holds ARC refrigerant handling licensing and licensed electrical trade qualifications, carries full insurance, and installs to Australian Standards. Every ducted installation comes with a 5-year manufacturer warranty and our 10-year workmanship guarantee.

Is ducted air conditioning worth the money?

For whole-home comfort, yes. Ducted is more expensive upfront than splits, but it conditions every room from one hidden system, heats as well as cools, is whisper-quiet indoors and is the option buyers value most — it typically adds more to resale appeal than it costs in buyer perception.

How much does ducted air conditioning cost to run?

A modern inverter ducted system costs roughly $1.00–$2.50 per hour to run when cooling a whole home, and far less when zoning limits conditioning to one or two areas. Correct sizing and zoning matter more to running costs than the brand you choose.

How long does a ducted system last?

With annual servicing, 15–20 years is typical for quality brands. The outdoor compressor is the hardest-working component — keeping filters clean and the system serviced is what gets you to the 20-year mark.

Ducted or split systems — which should I choose?

Choose ducted if you want whole-home comfort, have roof space and plan to stay long-term. Choose splits if you only need one or two rooms, have a tighter budget, or live in an apartment without roof access. We install both and will tell you honestly which suits your home.

Does ducted air conditioning heat as well?

Yes — modern ducted systems are reverse-cycle, meaning they heat in winter as efficiently as they cool in summer. Reverse-cycle is the cheapest form of electric heating available, which is why many Sydney households use their ducted system year-round.
