How Long Does Air Conditioning Installation Take?
Air conditioning installation time varies depending on the type of system, the size of your home, and the complexity of the setup. Understanding how long installation takes can help you plan and avoid surprises.
This guide outlines typical installation timeframes for split systems, ducted reverse cycle air conditioning, and evaporative cooling systems in Melbourne homes.
What Affects Installation Time?
No two installations are the same. Several factors influence how long the process will take:
- Type of air conditioning system
- Size and layout of the home
- Ease of roof or wall access
- Electrical requirements
- Whether it’s a new install or replacement
Simpler installations can be completed quickly, while larger or more complex jobs require additional time.
Split System Installation Time
Split systems are generally the fastest type of air conditioning to install.
- Standard installation: 3–6 hours
- More complex installs: up to 1 full day
Installation involves mounting the indoor unit, connecting the outdoor condenser, and completing electrical and refrigerant connections.
Ducted Reverse Cycle Installation Time
Ducted systems take longer to install due to the complexity of ducting and system design.
- Average installation: 1–2 days
- Larger or multi-storey homes: 2–3 days
This includes installing the central unit, running ductwork, setting up vents, and configuring zoning if required.
Evaporative Cooling Installation Time
Evaporative cooling systems are typically quicker to install than ducted reverse cycle systems.
- Average installation: 1 day
- More complex setups: up to 2 days
The process involves mounting the rooftop unit, connecting ducting, and setting up water supply and drainage.
Replacement vs New Installation
Replacing an existing system is often faster than a new installation because some infrastructure may already be in place.
- Replacing split systems: often completed in a few hours
- Replacing ducted systems: typically 1 day
- Full new installations: longer due to additional setup
However, older systems may require upgrades to electrical or ducting components.
What Happens During Installation?
Understanding the process can help set expectations.
- Assessment and system positioning
- Installation of indoor and outdoor components
- Connection of electrical and system controls
- Testing and commissioning
The system is tested to ensure it is operating correctly before completion.
Will Installation Disrupt My Home?
Most installations are completed with minimal disruption, but some noise and temporary access to certain areas will be required.
- Roof space access for ducted systems
- Wall penetration for split systems
- Temporary power shutdowns in some cases
Installers typically aim to minimise disruption and complete work efficiently.
How to Prepare for Installation
Simple preparation can help ensure the installation runs smoothly.
- Clear access to installation areas
- Move furniture away from walls or vents
- Ensure pets are secured
Preparation helps reduce delays and allows installers to work efficiently.
Final Thoughts
Air conditioning installation time depends on the type of system and the complexity of the job. Split systems can often be installed within hours, while ducted systems may take several days.
Understanding these timeframes helps set realistic expectations and ensures a smoother installation process.
