Air Conditioning Maroochy River

Much of Maroochy River sits below the 1-in-100-year flood line. Outdoor units must be mounted above the flood level (typically 300 to 600mm on raised pads or wall brackets), so confirm the quote includes this or the unit fails in the first big wet-season event. The council's flood search for the property gives the defined level, and mounting to that figure rather than a guess is what an insurer will ask about after a claim.

The floodplain traps humidity overnight. Systems without a strong dehumidify mode struggle to bring indoor RH below 65%, so rooms feel muggy even at 24°C. Sizing for the latent load means the unit runs longer at low speed and pulls more water out of the air, and the condensate line has to be sized and fallen for that volume rather than the trickle a southern installer expects.

A lot of the housing stock predates 1990 with fibro cladding, minimal insulation, and 63 A single-phase mains. Ducted installs often trigger electrical upgrades, so make sure the quote itemises this. Pre-2004 fibro also brings the Queensland asbestos rules into play for any wall penetration, and on acreage lots the service line from the road may be too long and too thin to carry a ducted unit without an Energex upgrade.

On humid days salt aerosol reaches inland from Marcoola, not as heavy as beachfront Golden Beach but enough that mid-range coil protection is worth the $100 to $200 upgrade. The tree cover on the older blocks helps here, because a condenser under a canopy is shielded from the breeze, though it then collects leaf litter and needs its coil cleared before each summer.
