UPGRADE YOUR OLD DUCTED AIR CONDITIONER TO A MODERN REVERSE CYCLE SYSTEM

With over 40 years of experience delivering comfort to homes across Western Australia, Ford & Doonan are specialists in ducted air conditioning replacements in Perth. If your existing ducted system is 10–15 years old, unreliable, or driving up your power bills, a modern reverse cycle upgrade can dramatically improve performance and efficiency.

Today’s refrigerated reverse cycle ducted systems are quieter, smarter and far more energy efficient than older models. With inverter technology, advanced zoning and iOS/Android app control, you can cool or heat your home precisely where and when you need it — without the excessive running costs associated with outdated systems.

How Much Does A Ducted Air Conditioning Replacement Cost?

The cost of a ducted air conditioning replacement in Perth varies depending on the size of the home and the scope of works involved. Unlike a simple split system swap, a ducted changeover requires assessment of access to the existing indoor and outdoor units, system capacity requirements, electrical supply, zoning layout and whether the property is single or double storey.

Additional factors such as roof space access, ductwork replacement, controller upgrades and switchboard compliance can also influence final pricing.

Because every home is different, we provide tailored quotations based on an on-site assessment to ensure the system is correctly sized and installed to current standards.

Can I Re-use My Ducting From My Current Air Conditioning System To My New Refrigerated Ducted System?

To determine the quality and condition of the ducting. Ford & Doonan recommend always replacing the ducting at the time of replacement for peace of mind.

It can be a similar story for the outlets. After many years of use, the once glistening white ceiling outlets can turn a shade of yellow and become stained. We replace them at the same time you’re getting the new system installed.

What Is The Ford & Doonan Difference?

A ducted air conditioning replacement is only as good as the way it’s installed. At Ford & Doonan, we prioritise long-term reliability, system performance and protection of your home. We operate a dedicated in-house service department, providing after-sales support long after installation is complete.

Our ducted systems are installed with twin 20mm PVC drain lines to reduce the risk of overflow during cooling operation, and all ductwork is properly suspended using fire-rated 75mm strapping to maintain optimal airflow and prevent sagging over time.

The indoor fan coil unit is mounted on threaded rod and positioned above an aluminium drip tray (where space permits), sitting on vibration-reducing feet to minimise operational noise and significantly reduce the risk of ceiling damage from water leaks.

Is It Cheaper To Repair Or Replace A Ducted Air Conditioner?

Whether it’s cheaper to repair or replace a ducted air conditioner depends on the age of the system and the nature of the fault. As systems get older, spare parts become increasingly difficult to source, and the cost of replacing major components — such as a printed circuit board (PCB), compressor or fan motor — can quickly add up.

For ducted systems over 10–15 years old, a significant repair can represent a large percentage of the cost of a full replacement. Much like an ageing vehicle, fixing one component does not guarantee long-term reliability, and additional failures can follow. In these cases, upgrading to a modern reverse cycle system can often provide better value, improved efficiency and greater peace of mind.
