What We Do

Ducted air conditioning services

Whether it's a new system, a tired old one or one that just isn't keeping up, we look after ducted air conditioning from the first site visit to ongoing servicing.

New ducted installations

For existing homes. We check your roof space, where the outdoor unit can go and where the outlets and return air grille will work best before we quote.

New builds & renovations

Bring us in before the plasterboard goes up and the duct runs, outlets and bulkheads can go exactly where you want them. Why timing matters.

Replacing an old ducted system

Noisy, struggling or costing too much to run? We assess the unit and the existing ductwork and tell you what can stay and what should be replaced.

Zoning & AirTouch control

Control zones or individual rooms from a wall panel or your phone, so you only heat and cool the rooms you're using. About AirTouch.

Repairs & servicing

Breakdowns, poor airflow and routine maintenance for all major ducted brands. Repairs & servicing.

Honest advice on ducted vs split

Ducted isn't right for every home. If one or two split systems would suit you better, we'll tell you.

How It Works

From site visit to switch-on

  1. Site visit — we look at the house, the roof space, where the outdoor unit can sit and how you use each room.
  2. System design — we size the unit to your home and plan the zones, outlet positions and return air.
  3. Fixed written quote — the unit, zones, controller and what's included, in writing. No phone estimates that change on the day.
  4. Installation — usually one to two days depending on the size of the home and roof access.
  5. Commissioning & handover — the system is commissioned, the controller is set up and we show you how to use your zones.

Sizing Matters

Getting the size right

A ducted system that's too small runs flat out and still struggles on the hottest and coldest days. One that's too big switches on and off, feels uneven and doesn't dry the air properly. We size every system around:

  • Floor area and ceiling height — the volume of air the system has to heat and cool.
  • Insulation — well-insulated homes hold their temperature; poorly insulated ones need more capacity.
  • Windows and sun — big west-facing windows and glass looking out over the water add a lot of heat in summer.
  • Who lives there — more people means more heat load, and we factor in how your household uses the space.

FAQs

Ducted air conditioning — your questions answered

How much does ducted air conditioning cost to install?

It depends on the size of your home, the number of zones, the capacity of the unit and how easy the roof space is to work in. A typical single-storey three or four bedroom Shoalhaven home is a very different job from a two-storey house with a tight roof. We visit, measure and give you a fixed written quote — no estimates over the phone that change on the day.

Will a ducted system fit in my roof?

Most Shoalhaven homes have enough roof space for the indoor fan-coil unit and the ductwork. Low-pitch roofs, skillion roofs and some slab-on-ground homes need a closer look, and occasionally a bulkhead or a slimline unit is the answer. We check access, clearances and where the outlets can go before we quote, so there are no surprises.

How many zones do I need?

A zone is a group of rooms you control together. Most family homes work well with three to five zones — for example living areas, the main bedroom and the other bedrooms. With AirTouch you can control every room individually from your phone, which means you only condition the rooms you're using.

Is ducted air conditioning expensive to run?

Not when it's sized and zoned properly. Modern inverter systems ramp up and down rather than switching on and off, and zoning means you're not cooling empty rooms. A correctly sized ducted system with zoning usually costs less to run than several split systems going at once. We'll show you the energy rating of the unit we recommend.

Should I get ducted or a few split systems?

If you want whole-home comfort with nothing on the walls, ducted is the better long-term choice and adds value at resale. If you only need one or two rooms conditioned, splits are cheaper and simpler. We'll give you an honest recommendation for your house and how you live in it — not the option with the biggest margin.

How long does a ducted installation take?

Usually one to two days depending on the size of the home and roof access. We confirm the timing in your quote, arrive when we say we will, and leave the house clean with the system commissioned and the controller set up.

Can you replace my old ducted system?

Yes. We look at the old unit and the existing ductwork together. Ducts and outlets that are in good condition and the right size can often stay; ducting that is old, damaged or too small for the new unit is better replaced while we're in the roof. We'll tell you which is which before we quote, and it's worth asking about rebates for upgrading an older system.

Can I add zoning or AirTouch to my existing ducted system?

Yes, though it isn't always a straight swap of the controller. Sometimes extra zone motors are needed, or the ductwork layout has to be changed so the system still runs efficiently once it's zoned. We'll look at your system and tell you exactly what's involved before you spend anything.

Do you install ducted air conditioning in new builds and renovations?

Yes, and the earlier you talk to us the better. Planning the unit, duct runs, outlets and return air grille before the plasterboard goes up gives you more options, fewer bulkheads and a neater result than fitting it in at the end of the build.

Which ducted brands do you install?

Midea, Mitsubishi Heavy Industries, Mitsubishi Electric, Daikin, Fujitsu and LG, with AirTouch zoning. Most of the brands we install offer a five-year manufacturer's warranty on residential systems and Midea offers ten. We'll recommend the unit that suits your home and budget rather than pushing one brand.

Do you repair and service ducted systems?

Yes. We repair and maintain ducted systems for all major brands, including ones we didn't install. Regular servicing keeps the filters, coil and drain clean and helps the system run efficiently.

Do you install ducted air conditioning in my area?

We cover the whole Shoalhaven, including Nowra, Bomaderry, Berry, Jervis Bay, Huskisson, Vincentia, St Georges Basin, Sussex Inlet, Culburra Beach, Ulladulla, Mollymook and Milton.
