Commercial HVAC
Done Without Disruption

Air conditioning for offices, retail spaces, warehouses, and hospitality venues across the Central Coast and Lake Macquarie. Gary designs systems that keep your staff and customers comfortable — and installs them without shutting down your business.

Commercial HVAC

Your Business Needs More Than a Domestic Installer

Commercial HVAC is a different discipline to residential work. The load calculations are more complex, the equipment is heavier-duty, the compliance requirements are more stringent, and the stakes are higher — a failed system in a retail shop on a 40°C day costs you customers and revenue.

Gary has extensive experience designing and installing commercial HVAC systems across the Central Coast — from small professional offices to large retail tenancies, medical centres, and industrial warehouses. He understands the specific requirements of commercial environments: after-hours installation to avoid disrupting your business, equipment that can handle continuous operation, and systems designed for the actual occupancy and heat loads of commercial spaces.

As a VRF/VRV specialist, Gary can design sophisticated multi-zone systems for larger commercial premises — giving you independent temperature control across different areas from a single outdoor unit array, with energy recovery between zones.

"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."
