Upgrading your old split system doesn’t always mean ripping out everything and starting from scratch. Many Melbourne homeowners are now considering hybrid upgrades, where parts of the existing system—such as ducting or wiring—are reused to save money and reduce waste. But how practical is this approach, and does it still qualify for Victorian Energy Upgrades (VEU) rebates? Let’s dive into the details.

✅ What Is a Hybrid Upgrade?

A hybrid upgrade means replacing only certain parts of your existing system—usually the outdoor compressor or indoor wall units—while keeping other components like ducting, wiring, or brackets intact.
This option is popular among homeowners who:

Have relatively new or intact ducting that doesn’t need replacement.
Want to switch to a reverse cycle energy-efficient system for heating and cooling.
Are looking for a cost-effective and faster installation.

✅ When Can You Reuse Existing Ducting or Components?

Not every system is compatible with hybrid upgrades. Here’s when reusing components works:

Good Condition Ducting – If your ductwork is clean, properly insulated, and undamaged, it can often be reused.
Compatible System Design – The new split or reverse cycle system must match the airflow requirements of the existing ducting.
No Gas System Integration – If you’re switching from a gas heater to a reverse cycle system, new electrical wiring and system upgrades are usually required.
Professional Inspection – A certified installer must assess whether reusing old parts meets VEU standards.

✅ Does a Hybrid Upgrade Qualify for VEU Rebates?

The Victorian Energy Upgrades (VEU) program focuses on energy efficiency and carbon reduction, so eligibility depends on:

Approved Products Only – The upgraded system (even if partial) must be listed as a VEU-approved product.
Significant Energy Savings – Rebates are usually provided if the new system results in measurable energy efficiency gains.
Certified Installers – Only installations by accredited VEU partners. Greentastic Pty Ltd works closely with Certified Installers, qualify for rebates.

👉 Tip: Even if you’re reusing ducting, the new unit’s energy efficiency rating is what determines the rebate.

✅ Benefits of a Hybrid Upgrade

Cost Savings – Reusing ducting or wiring lowers installation costs.
Faster Installation – Minimal structural changes mean quicker setup.
Eco-Friendly – Reduces waste by keeping functional components.
Energy Efficiency – Modern reverse cycle systems can cut heating and cooling costs by up to 60%.

✅ When Should You Replace Everything Instead?

A full system replacement is recommended if:

Ducting is old, leaking, or poorly insulated.
Your existing split system is more than 10–12 years old.
You’re switching from gas heating to an all-electric system.
