Ducted Air Conditioning Sutherland Shire

The fan coil goes in the upstairs cavity, sized to the height available near the ridge, and the ground-floor rooms are fed by duct drops through wall cavities or a neat bulkhead along a hallway. Upstairs and downstairs run as separate zones, so the bedrooms can be cooled at night without conditioning the living areas. We measure the cavity before quoting so the design is fixed, not guessed.

Yes, but it is a design job rather than a standard install. With little or no cavity, the fan coil goes in a bulkhead, a dropped ceiling section or a cupboard, and the ducts run in bulkheads to each room. The large glass wall facing the water drives the heat load, so the living zone is sized for it and kept separate from the bedrooms. The condenser goes on the side path, away from the canal where possible.

Yes. Many first-generation systems in these estates were sized for their era with little or no zoning, and they are now at the end of their life. We inspect the existing ducts and insulation to see what can be reused, then size a new inverter system to the house as it is today, usually with upstairs and downstairs zoned apart. If the ducting is sound, the job costs less than a full install.

Almost always. With living on one level, bedrooms a half-flight up and a rumpus below, a single zone overcools one floor while another stays warm. The steep-pitched roofs in Kareela usually give room for a full-size fan coil, so the challenge is the ducting between levels, not the plant. We zone each level and size west-facing rooms on the ridge for afternoon sun.

On a hard-stand or pad on the house side of the block, away from gum drop, garden beds, timber decks and fences. On streets with a bushfire attack level rating we fit ember-resistant guards as the rating requires. A clear position also keeps the coil from choking with leaves and bark, which matters in Engadine, where still, high-30s January afternoons push the system hard.
