The Renovation Decision Most Homeowners Leave Too Late

Renovations are full of visible decisions. Kitchens, bathrooms, flooring, lighting. But one of the most important upgrades for long-term comfort often gets pushed to the bottom of the list until it’s too late – ducted air conditioning.

Once plaster is up and ceilings are closed, installing ducted air conditioning becomes significantly more expensive, more disruptive, and in some cases, not viable at all. For homeowners renovating across Geelong, the Bellarine Peninsula, and the Surf Coast, early planning makes the difference between a seamless upgrade and a costly compromise.

Why Renovations Are the Ideal Time for Ducted Air Conditioning

Renovation projects create a rare window where ceilings, wall cavities, and roof spaces are already accessible. This allows ducting, vents, and zoning systems to be installed cleanly, efficiently, and with minimal structural work.

When ducted air conditioning is planned at the same time as framing and electrical work, installers can optimise airflow, hide all components properly, and position vents exactly where they work best – not where access allows.

Homeowners who wait until after renovations often face bulkheads, visible ducting, or limited zone control that reduces both comfort and resale value.

System Sizing Should Match the Renovated Home, Not the Old One

One of the most common renovation mistakes is reusing old air conditioning assumptions. Renovations change everything – room sizes, ceiling heights, insulation levels, window placement, and even how the home is used.

Ducted air conditioning systems must be sized to the finished home, not the pre-renovation layout. An undersized system struggles during Geelong heatwaves, while an oversized system cycles inefficiently and costs more to run.

Proper heat load calculations during the planning phase ensure the system delivers consistent comfort across every room without unnecessary energy use.

Zoning Is Where Renovation Planning Pays Off

Zoning allows different areas of the home to be heated or cooled independently. During renovations, zoning design is far more flexible because duct runs and dampers can be installed exactly where needed.

This is especially valuable for growing families, home offices, or multi-level renovations where room usage changes throughout the day. Smart zoning systems like Advantage Air allow homeowners to avoid heating or cooling unused rooms, reducing energy bills year-round.

Once plaster is installed, retrofitting zoning becomes complex and expensive, making early planning critical.

Vent Placement Affects Comfort More Than You Think

Vent placement is not just an aesthetic decision. During renovations, ceiling heights, beam locations, and lighting layouts all influence where vents should be positioned for effective airflow.

Poorly planned vent placement can create drafts, uneven temperatures, or dead zones that no thermostat can fix. Renovation-stage installation allows vents to be positioned for performance first, appearance second – without compromise.

Electrical and Structural Coordination Matters

Ducted air conditioning requires coordination with electricians, builders, and sometimes structural engineers. Return air placement, outdoor unit positioning, and power supply all need to be planned before final construction stages.

When ducted systems are considered early, these elements integrate cleanly into the renovation. When left late, homeowners may face exposed conduit, awkward unit placement, or unexpected electrical upgrade costs.

Renovations Can Unlock Government Rebates

Many ducted air conditioning systems installed during renovations may be eligible for Victorian government rebates when replacing inefficient heating or cooling systems.

Eligibility depends on system type, efficiency ratings, and installation timing. Planning early allows homeowners to choose rebate-approved systems and ensure all compliance requirements are met before installation.

You can learn more about available incentives on the government rebates page, or have eligibility assessed during the quoting stage.

Renovation Delays Cost More Than You Expect

Installing ducted air conditioning after plaster goes up often means cutting ceilings, patching, repainting, and compromising design outcomes. These costs quickly exceed the savings of delaying the decision.

Early planning reduces labour time, avoids rework, and delivers a cleaner final result. It also shortens overall project timelines, keeping renovation schedules on track.

Local Experience Makes a Difference

Homes across Geelong, Torquay, Ocean Grove, Lorne, and the Bellarine Peninsula face different conditions – coastal air, humidity, insulation variations, and seasonal temperature swings.

Working with a local installer ensures your ducted air conditioning system is designed for real local conditions, not generic assumptions. This results in better performance, longer system life, and lower running costs.

Plan Early, Live Comfortably

If you are renovating and considering ducted air conditioning, the best time to plan is before plaster goes up. Early design decisions deliver better comfort, better efficiency, and fewer compromises.
