Is Ducted Air Conditioning Right for Your Wollongong Home?

Most of the homeowners we talk to are dealing with one of these:


  • Upstairs bedrooms that are too hot to sleep in come January
  • Three or four split systems on the walls, all noisy and all expensive to run
  • An old ducted system that's struggling, rattling or blowing warm air
  • A renovation or extension that's the perfect moment to do it properly
  • Wanting to add value before selling or renting the property



If any of these sound familiar, ducted air is worth a look. We'll come out, check your home and tell you honestly whether ducted is the best fit or whether a split or multi-split system makes more sense.

What Is Ducted Air Conditioning?

Ducted air conditioning is a whole-home system that heats and cools every room from one central unit. Conditioned air travels through insulated ducts in the roof and comes out through discreet ceiling vents. Instead of a unit on every wall, you get even comfort right through the house with one controller.


A typical reverse cycle ducted system includes:


  • Indoor fan coil unit, tucked away in the roof space
  • Outdoor condenser unit, placed outside
  • Insulated supply ductwork running to each room
  • Ceiling vents and diffusers in each room
  • Return air grille with filter that draws air back to the system
  • Zone dampers and a thermostat or smart controller, so you can heat or cool only the rooms you're using


Reverse cycle means the same system cools you in summer and heats you in winter, which makes it one of the most efficient ways to heat a home in NSW.

Why Choose Ducted Systems for Wollongong?

Wollongong's climate asks a lot of an air conditioner. Summers are warm and humid, winters can be surprisingly cold, particularly in suburbs closer to the escarpment, and homes along the coast deal with salt air all year. A well-designed ducted system handles all of that.


  • Whole-home comfort: every room stays at an even temperature
  • Humidity control: takes the stickiness out of muggy February nights
  • Quiet operation: the noisy parts sit in the roof and outside
  • Zoning saves money: only heat or cool the rooms you're using
  • Cleaner indoor air: air is filtered as it circulates
  • No wall units: just neat ceiling vents that suit any style of home
  • Added property value: ducted air is a strong selling point for Illawarra buyers and renters

How We Size Your Ducted System

Getting the size right is the single most important part of a ducted install. Ducted systems are measured in kilowatts (kW) of cooling and heating capacity. Too small and the system runs flat out without keeping up. Too big and it short-cycles, leaves the air clammy and costs more to run.


We don't quote from a phone call or a floor plan alone. At your free in-home assessment we do a heat load assessment of your home, looking at:


  • Room sizes, ceiling heights and open-plan areas
  • Which way the house faces and how much afternoon sun it gets
  • Insulation, windows and glazing
  • Single or double storey, and how each space is used
  • Roof space access and room for the indoor unit and ductwork
  • Where the outdoor unit can go, including protection from coastal salt air



From there we recommend the right kW capacity, zone layout and inverter model for your home and budget, and put it all in a written, fixed-price quote.

Installation Requirements

Every home is different, but a ducted system generally needs:


  • Ceiling space of around 300 to 350mm for the indoor unit and ducting (we use slimline units for tighter roofs)
  • A dedicated power circuit for the system
  • A suitable outdoor unit position, with corrosion protection for homes near the coast
  • Weather-rated insulated ductwork to stop energy loss in hot roof spaces
  • Drainage access for condensate
  • A correctly sized return air grille for good airflow



Not sure your home ticks every box? That's what our assessment is for. We can retrofit ducted air conditioning into most Wollongong homes, including older brick homes and properties with tight ceiling space.

Ducted vs Split Systems

Feature Ducted Air Conditioning Split System Air Conditioning
Coverage Whole-home One room per unit
Appearance Discreet ceiling vents Wall-mounted indoor heads
Noise Very quiet (outdoor + roof space) Indoor fans can be audible
Zoning Yes – rooms controlled independently No zoning
Cost to install Higher upfront Cheaper per room
Cost to run Cheaper for full-home use Expensive when running multiple units
Best for 3+ bedroom homes, new builds, renos Single rooms, small units, rentals

If you only need to cool one or two rooms, a split system can be the smarter choice, and we install those too. If you want comfort through the whole house, ducted usually wins on comfort, looks and running costs over time.

One of the key concerns for Wollongong households today is the rising cost of electricity. That’s why we specialise in installing energy efficient ducted air conditioning systems that can cut your heating and cooling bills by up to 60%.

Common Mistakes to Avoid

  1. Choosing on price alone. Cheap installs often mean undersized ductwork and poor airflow design.
  2. Oversizing the system. It short-cycles, leaves humidity behind and uses more power.
  3. Poor outdoor unit placement. Coastal salt air corrodes coils unless the right protection is used.
  4. Skipping zoning. Without zones, you're paying to cool rooms nobody is in.
  5. Neglecting annual servicing. Leads to blocked filters, mould, refrigerant loss and warranty problems.

Servicing, Warranties and Peace of Mind

Every new ducted installation is covered by our 5-year workmanship guarantee, on top of the manufacturer's warranty on the equipment. Manufacturers generally expect systems to be serviced regularly, so we recommend a professional service once a year to keep your system efficient, the air clean and your warranty in good standing.

Energy Efficiency and Rebates

Eligible households may be able to save on a new high-efficiency reverse cycle system through the NSW Government's Household Energy Saving Upgrades program, which is part of the NSW Energy Savings Scheme. The discount comes off your quote upfront, so there's nothing to claim afterwards. How much you save depends on the size and energy rating of the system. We'll check your eligibility and include any discount in your quote.

Ducted Air Conditioning Across Wollongong and the Illawarra

We're a local ducted air conditioning installer, and we work right across the region. That includes the northern suburbs around Thirroul and Towradgi, the Wollongong CBD, Figtree and the suburbs beneath the escarpment, Port Kembla on the coast, and Dapto, Albion Park, Oak Flats, Warilla and Shellharbour around Lake Illawarra. Further south, we look after homes in Kiama, Gerringong and Jamberoo, and we travel to Nowra on request.



Every part of the Illawarra is a little different. Homes near the beach need outdoor units protected from salt air. Houses tucked under the escarpment get cooler nights and need solid heating. Newer estates around Albion Park and Shellharbour often have larger open-plan layouts that suit multi-zone systems. We design each system around those local conditions.

Ducted Air Conditioning FAQs for Wollongong Homeowners

  • How much does it cost for ducted air conditioning in Wollongong?

    A new ducted system in Wollongong typically costs between $7,000 and $15,000 or more. The price depends on the size of your home, the kW capacity, the number of zones, the brand, and how easy the roof space is to work in. We provide free, fixed-price written quotes after an in-home assessment.

  • Can you install ducted air conditioning in an older home?

    In most cases, yes. We retrofit ducted systems into most Wollongong homes, including older brick homes. You'll generally need around 300 to 350mm of ceiling space, and we use slimline indoor units where roof space is tight.

    Zoning splits your home into areas, such as bedrooms and living areas, that you can heat or cool separately. It saves energy because you're not running the system for empty rooms. We recommend zoning for almost every ducted install.
