Ducted Air Conditioners

A Ducted system uses one central indoor unit connected to a network of ducts in the ceiling or under the floor to heat or cool multiple rooms at once.

Air is delivered through discreet ceiling or floor vents, keeping the system largely hidden.

Correct sizing is critical and is based on:

• Total floor area

• Ceiling height

• Insulation and glazing

• Orientation and climate zone

Installers use a whole-of-home heat load calculation to determine the correct system size.

Yes. Rinnai Ducted systems are reverse-cycle, providing efficient heating in winter and cooling in summer.

They are often cheaper to run than traditional gas heating.

Ducted air conditioning is ideal if:

• You want whole-home comfort

• You’re building or renovating

• You prefer a clean, uncluttered look

• You want to heat or cool many rooms at the same time

Modern Ducted systems are highly efficient when:

• Correctly sized

• Zoned properly

• Used with insulated ductwork

Efficiency varies by brand and model, so energy star ratings matter.

With correct installation and maintenance:

• 12–20 years is typical

Ducting may last longer than the mechanical components.
