If you’re planning a new HVAC installation in Melbourne or Brisbane, one of the most common questions is: how long will it take? The timeline for installing a commercial HVAC system can vary widely depending on the building size, system complexity, and custom requirements.
Let’s break down the key factors and provide a realistic timeline so you can plan with confidence.
Typical Installation Timeframes
- Small to Medium-Sized Buildings (Offices, Shops, Cafés)
- 3 to 7 business days
- Straightforward HVAC projects with ducted or split systems can be completed in less than a week.
- Large Commercial Premises (Factories, Shopping Centres, Multi-Storey Offices)
- 2 to 4 weeks
- These projects require more complex ductwork, zoning, and compliance checks, often including cranes for rooftop units.
Factors That Impact Installation Time
1. Project Size and Scope
The larger and more complex the building, the longer it takes to install the HVAC system. A warehouse will differ greatly from a retail shop or office fit-out.
2. System Type and Design
- Ducted systems take longer due to air distribution planning.
- Split systems or VRF units may be faster but still require careful installation and configuration.
- Custom HVAC solutions or energy-efficient designs also need extra time for engineering approval.
3. Site Conditions
Tight ceilings, heritage buildings, or difficult rooftop access can slow down the process. Installers must sometimes work around existing tenants or ongoing construction.
4. Permits and Compliance
In both Melbourne and Brisbane, permits and approvals may be required before starting installation. Delays here can impact your project timeline.
5. Availability of Parts and Equipment
Backorders for compressors, ducting, or smart control systems may delay installation unless planned in advance.
