How it works

One hidden system. Every room covered.

Switch between cooling and heating, then choose a zone to see how a ducted system moves air around a home.

Ducted air conditioning
How a whole-home ducted system works Cross-section of a single-storey house. An outdoor unit beside the house connects to a concealed central unit in the roof space. Insulated ducts run from the central unit to ceiling outlets in two bedrooms and the living area, and a return-air grille in the hallway draws air back to the unit.

Cooling, whole home. The concealed unit sends cooled air through insulated ducts to every outlet. Air returns through the hallway grille and the cycle repeats.

  1. Outdoor unit beside the house, connected by refrigerant lines.
  2. Central unit hidden in the roof space, so nothing hangs on your walls.
  3. Insulated ducts carry conditioned air across the ceiling.
  4. Ceiling outlets deliver conditioned air into the rooms.
  5. Return grille draws room air back to be cooled or heated again.

Illustrative layout only. Zoning uses dampers in the ducts, and which areas can run together depends on the installed controls and minimum airflow of the system we assess for your home.

Replacing an old system

Ageing ducted unit? Three steps to a new one.

Heating replacements
  1. Assess the old system

    We inspect the existing unit, roof space, ducts and switchboard, then tell you what can stay and what should go.

  2. Plan ducts and zones

    A written quote with the unit, outlet positions and any zoning that suits your layout, priced before work starts.

  3. Install and hand over

    Old equipment removed, new system installed to standard, then a walkthrough of the controls before we leave.
