"We highly recommend Lilac HVAC. They fixed three previously installed units that were incorrectly linked at our business premises. Very professional and knowledgeable."
- Gosford Dental Centre

When the Air Conditioning Is Down, So Is the Business

A hot shopfront empties. A stuffy office slows everyone in it. And a system that was never installed right generates complaints every month until someone finally fixes the cause.

Lilac HVAC installs, repairs, and maintains commercial air conditioning and ventilation across the Central Coast: VRF/VRV, packaged units, cassettes, and splits for offices, retail, hospitality, and medical suites. One local contractor for the air conditioning and the exhaust systems around it, with fixed-price quotes and work scheduled around your trade where possible.

Comfort your customers and staff never have to think about.

What Lilac HVAC Does For Businesses

VRF/VRV, packaged units, cassettes, and splits specified and installed for offices, shops, and new fit-outs, to Hitachi and Temperzone spec.

Systems that stop mid-trade diagnosed at the cause and fixed properly, with same-day support where possible.

Servicing every three to six months with a written report for your records, so small faults get caught before they close the shop.

Kitchen, amenities, and carpark exhaust supplied, installed, and maintained alongside the air conditioning.
