Why Ducted?
Whole-Home Comfort, One Quiet System
If you've ever had a split system in the living room that leaves the bedrooms sweltering, or a home where every room needs its own wall unit, ducted air conditioning is the answer. A properly designed ducted system delivers conditioned air to every room through concealed ductwork — no wall units, no visible equipment, just comfortable air wherever you need it.
On the Central Coast, where summer temperatures regularly push past 38°C and coastal humidity makes the heat feel even worse, a zoned ducted system gives you precise control over which areas of your home are cooled or heated and when. You only condition the spaces you're using, which keeps running costs down.
Gary designs each system from scratch for the specific home — calculating heat loads for each zone, selecting the right unit capacity, and planning the duct layout to ensure even airflow throughout. A poorly designed ducted system is expensive to run and never quite comfortable. A well-designed one is a genuine quality-of-life upgrade.
How It Works
From Quote to Commissioning
01
Site Assessment
Gary visits your home to assess ceiling space, room layout, insulation, and sun exposure. He takes measurements and discusses your comfort priorities and budget.
02
Custom Design & Quote
Gary designs a zoned system tailored to your home — duct layout, diffuser positions, zone configuration, and unit selection. You receive a fixed-price quote with no surprises.
03
Installation
Gary and his team install the system with minimal disruption. Ductwork is run through ceiling cavities, diffusers are fitted flush to the ceiling, and the outdoor unit is positioned discreetly.
04
Commissioning & Handover
Every zone is tested and balanced for even airflow. Gary walks you through the controller, zone settings, and maintenance requirements before he leaves.

FAQ
Frequently Asked Questions
Ducted system costs vary based on home size, number of zones, ceiling space, and the brand and model selected. A typical 3–4 bedroom home installation ranges from $8,000–$18,000 supply and install. Gary provides free, detailed fixed-price quotes so you know the full cost before committing.
Most homes with accessible ceiling cavities are suitable. Gary will assess your ceiling space, roof pitch, and structural layout during the site visit. Homes without ceiling access may be better suited to a multi-head split system or VRF system.
A typical residential ducted installation takes 2–3 days. Larger homes or complex layouts may take longer. Gary will give you a realistic timeframe in the quote.
Zoning divides your home into independently controlled areas — for example, living areas and bedrooms. You can cool only the zones you're using, which significantly reduces running costs. For most homes, zoning is a worthwhile investment.
Yes. Gary regularly replaces ageing ducted systems — sometimes reusing existing ductwork where it's in good condition, or replacing it entirely where needed. He'll assess the existing installation and advise on the most cost-effective approach.

"Gary came out to my place on pretty short notice and did a great job on maintenance on our ducted system. He's a friendly polite guy and his offsider was great as well — very reasonable price and tidy work. I'll definitely recommend Lilac HVAC and re-engage them for future work."
