Serving Tuggerah and the northern Central Coast with professional air conditioning installation, servicing, and emergency repairs.
Many new homes come with a single air conditioner in the living area and little else. It's the first proper summer in the house when people start looking for something better.
Gary Lui at Lilac Air Conditioning is happy to start from whatever's already there. Sometimes the answer is a split system in the main bedroom and nothing more. Sometimes the original unit is too small for the open-plan space it was meant to cool, and replacing it makes more sense than nursing it along. Either way you get a straight opinion rather than a pitch for the biggest unit on the price list.
Tuggerah sits beside Tuggerah Lake, a little further from the ocean than the beachside suburbs, and summer afternoons here can get very hot. That's a big load for a small system. We install split, multi-head and ducted systems for new builds and renovations, and we look after commercial premises too.
Wyong, Kanwal, Charmhaven and Gorokan are all part of the same patch. A quote for any of them starts the same way: a visit, a proper measure-up, and a price in writing that won't move.
Local Climate Note
Tuggerah Lake keeps the air humid through summer, and newer homes on small blocks can hold the day's heat well into the evening.
A builder's system is often a basic one and may not suit how you live. If yours is too small or only covers one room, Gary can add to it or replace it, and he'll say plainly which option is likely to give you better value over the next few summers.
With so much building going on, there's a steady mix of new offices, shops and trade premises needing cooling. Lilac Air Conditioning quotes commercial work as a fixed price and can fit installs around handover dates or trading hours, so a new fit-out isn't held up waiting on air conditioning.
