Our Services
Ventilation Solutions
"Fresh air, compliance, and comfort — all covered."
Supply, installation, and maintenance of commercial and residential ventilation systems including kitchen exhaust, bathroom exhaust fans, and carpark ventilation. Ensuring air quality, occupant comfort, and regulatory compliance.
Overview
Good ventilation is invisible when it works and immediately obvious when it doesn't. Stale air, condensation, mould, odours, and overheating are all symptoms of inadequate ventilation — and in commercial settings, poor ventilation can also mean non-compliance with the Building Code of Australia.
Lilac Air Conditioning provides ventilation design, installation, and maintenance for residential and commercial properties across the Central Coast. From a single bathroom exhaust fan to a full commercial kitchen extraction system, every job is done to Australian Standards with the documentation to prove it.

Frequently Asked Questions
Yes. We install and maintain commercial kitchen exhaust systems that comply with AS 1668.2 and local council requirements. All work is documented for compliance purposes.
Carparks require mechanical ventilation systems to manage carbon monoxide levels in accordance with the Building Code of Australia (BCA Section F). We design and install compliant systems for new and existing carparks.
Yes. We replace residential and commercial exhaust fans of all types. We can upgrade to quieter, more energy-efficient models with a like-for-like or improved replacement.
HRV systems extract stale air from a building while recovering the heat (or coolness) from that air and transferring it to the fresh incoming air. This improves air quality without the energy loss of simply exhausting conditioned air.
Yes. The BCA specifies minimum ventilation requirements for habitable rooms, wet areas, commercial kitchens, and carparks. New builds and significant renovations must comply. We can assess your property and advise on compliance.

"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."
