Why It Matters
The Right Installation Makes All the Difference
A split system is only as good as its installation. An undersized unit runs constantly and never achieves the set temperature. An oversized unit short-cycles, wears out faster, and leaves the room feeling clammy. Poor installation — inadequate pipe insulation, incorrect refrigerant charge, badly positioned indoor unit — can add hundreds of dollars to your annual running costs and halve the life of the equipment.
Gary has been installing split systems across the Central Coast for over 15 years. He takes the time to assess your room properly, recommends the right capacity and brand for your situation, and installs to manufacturer specification every time. Every installation includes a full commissioning check and a walkthrough of the system controls before he leaves.
As an authorised Hitachi and Temperzone installer, Gary has access to the full product range and can supply and install in a single visit — no waiting for a separate delivery.

FAQ
Frequently Asked Questions
Split system installation costs vary based on the unit size, location, and complexity of the installation (e.g. single-storey vs two-storey, brick vs weatherboard). Gary provides free, fixed-price quotes so you know the full cost before any work begins. Call 0401 764 917 for a no-obligation quote.
The right size depends on your room dimensions, ceiling height, insulation quality, window orientation, and sun exposure. Gary will assess your space and recommend the correct capacity — oversizing or undersizing both waste money and reduce comfort.
A standard single split system installation typically takes 3–5 hours. Multi-head systems or installations requiring longer pipe runs take longer. Gary will give you a realistic timeframe when he quotes the job.
Gary can supply and install in a single visit, or install a unit you have already purchased. Supplying through Gary ensures the unit is correctly specified for your space and comes with full installer warranty support.
It depends on your home and needs. Split systems are ideal for cooling or heating individual rooms or open-plan areas. Ducted systems provide whole-home climate control but cost more to install. Gary can advise on the best option for your situation.

"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."

"Very impressed with Gary from Lilac. He arrived on time and was very professional. The job didn't take long at all and our new AC unit has taken the edge off this winter. Highly recommend."
