Authorised Hitachi Installer
Hitachi Air Conditioning
Central Coast Specialist
Gary is an authorised Hitachi installer on the Central Coast — supplying, installing, and servicing the full Hitachi residential and commercial range. Manufacturer warranty support, expert installation, and genuine Hitachi parts.
Why Hitachi
Why Gary Recommends Hitachi
Gary has been installing Hitachi air conditioning systems for over a decade, and it's the brand he recommends most often to his residential and commercial clients. The reason is simple: Hitachi systems are built to last in Australian conditions, perform consistently in extreme heat, and are backed by strong manufacturer support.
Hitachi's residential range covers everything from compact split systems for apartments to large-capacity units for open-plan homes. Their commercial range includes VRF/VRV systems capable of serving entire office buildings from a single outdoor unit array. The energy efficiency ratings across the range are among the best available, which matters on the Central Coast where air conditioning runs hard through summer.
As an authorised installer, Gary has access to the full Hitachi product range, genuine parts, and manufacturer technical support. Installations completed by an authorised installer also qualify for the full manufacturer warranty — which can be voided if the system is installed by an unaccredited contractor.

"From start to finish, Gary was a pleasure to deal with when we needed an additional outlet installed to our ducted aircon system. He is a highly knowledgeable professional who takes pride in his work and the service he delivers to customers."

"We had four air conditioners installed and couldn't be more satisfied. From the initial quotation to the final installation, communication was always prompt and professional. The installer arrived on time, worked diligently, and ensured everything was installed to a high standard. Excellent workmanship and very reliable service."

"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."
