What strata air conditioning covers

Strata air conditioning means the shared plant that serves a building: air conditioning in lobbies, gyms, meeting rooms and managers' offices, VRF or VRV systems where one outdoor unit serves many indoor units, and the exhaust fans for carparks, bathrooms and kitchens. Lilac Air Conditioning looks after all of it for strata buildings.

Gary Lui is the owner and the person you deal with. There isn't a call centre between a strata manager and the person doing the work.

A quote an owners corporation can vote on

Committees rarely have a technician in the room when they discuss a quote, so it has to explain itself. Lilac Air Conditioning writes strata quotes to stand on their own. Where a committee wants options, such as repair this year or replace in two, the quote can lay them out together so the decision is about the building rather than a spec sheet.

  • A plain-language description of the work and why it's needed.
  • A fixed price in writing, with no hidden extras.
  • What's included and what isn't.
  • The brand and model being supplied.
  • Access and timing, including the days residents will notice the work.

What we look at on the first visit

The free on-site assessment starts with the plant itself: where it sits, how old it is, whether it's running, and how a technician reaches it. Gary asks to see any earlier service records, because they say a lot about what's been done and what hasn't.

Access and timing are agreed with the strata manager before work starts, and anything that could affect residents goes in the quote.

Common property, lots and exhaust

The work Lilac Air Conditioning quotes for owners corporations is on common property. Air conditioners inside individual lots are a separate matter, and the by-laws on what an owner may install differ from building to building, so the strata manager is the right first call.

Exhaust ventilation often falls under common property too, because ducts and risers pass through shared walls and ceilings. Gary can quote bathroom fans, carpark extraction and kitchen exhaust together where it makes sense, so the committee deals with one tradesman rather than three.

Maintenance records and long-term planning

After a service visit Gary can put what he checked, found and did in writing. Over time that becomes a history the committee can point to when it plans maintenance and budgets for replacing ageing plant.

Lilac Air Conditioning gives an honest view on whether a unit has useful years left or is due for replacement, and says so even when the answer is to keep repairing it. Breakdowns in common areas are treated seriously, and Gary aims to respond the same day.

"Not expecting our air conditioning to stop on one of the hottest days of the year, I contacted Gary and he advised me straight away his availability and turned up to review our situation. Unable to source spare parts for our older unit, Gary was up front and honest in quoting, supply and installation. I would highly recommend Gary for his experience, knowledge and thorough communication. Thanks Gary"

"We recently had our ducted air conditioning system serviced and were very happy with the service we received. Gary is friendly, knowledgeable and professional. Everything was explained clearly, and the service was completed efficiently. If you are located on the Central Coast, we would definitely recommend Lilac HVAC and will happily use them again in the future."
