"What a breath of fresh air! Gary turned up when he said he would, was very professional and respectful of my house, and offered me a range of solutions for my A/C needs."
- Sarah K.

One Local Number for the Life of Your Home's Air Conditioning

Finding a good aircon tech shouldn’t be the hard part. Someone who answers the phone, quotes what they’ll actually charge, does tidy work in your home, and tells you the truth about repair versus replace.

That’s the whole pitch at Lilac HVAC. Led by owner Gary Lui, we install, repair, and service air conditioning for homes across the Central Coast. You deal with the same local business at every step, this year and in five years when the system needs its next service.

Your home's air conditioning, sorted by a local business that'll still answer your call next summer.

What Lilac HVAC Does For Homeowners

Split, multi-head, and ducted systems sized for your home and the Coast climate, installed to Hitachi and Temperzone spec.

Units that stop cooling, leak, rattle, or die on the hottest day of the year, diagnosed and fixed properly, with same-day support where possible.

Annual coil cleans, filter cleans, and drain flushes that keep the system efficient and catch problems before January does.

Exhaust fans installed and vented properly, so steam and mould leave the house instead of settling in it.

Frequently Asked Questions

What air conditioning services do you offer for homes?

Lilac HVAC installs, repairs, services, and replaces split, multi-head, and ducted air conditioning for Central Coast homes, plus bathroom and kitchen exhaust ventilation. One local business for everything your home’s air conditioning needs.

It depends on the rooms, the roof space, and the budget. Splits suit one or two rooms, multi-head runs several rooms off one outdoor unit, and ducted suits whole-home comfort. We assess your home and recommend the option that fits how you live, not the one with the biggest price tag.

Where possible, yes. If we can’t get to you the same day, we’ll give advice over the phone and book the next available time. Call 0401 764 917.

Every home is different, so we quote each job individually. You get a fixed price before any work starts, with no hidden extras, and free estimates on larger installs.

Once a year for most Central Coast homes, ideally before summer. Near the coast, annual servicing also protects coils and outdoor units from salt-air wear.

Yes, and honestly. We assess the system’s age, condition, and fault history, then give you the numbers for both options. If a repair is the smarter spend, that’s what we’ll recommend.

Yes. Lilac HVAC is licensed and insured in NSW, and all work is completed to Australian standards. Gary is also an authorised Hitachi and Temperzone installer.

Lilac HVAC covers homes across the Central Coast, including Gosford, Erina, Tuggerah, Wyong, and Woy Woy, plus Cooranbong, Morisset, and Toronto in southern Lake Macquarie.
