A ducted system needs an indoor fan coil in the roof space, insulated ductwork run to every outlet, ceiling penetrations and grilles, a zoning system with motorised dampers and a controller, and usually a dedicated circuit the existing switchboard cannot always provide. A split system is one indoor head, one outdoor unit and a short pipe run between them. The comparison is closer to one appliance versus a whole-house system.",{"q":323,"a":324},"Does an oversized air conditioner cost more to run?","Yes, and it also performs worse, which is counter-intuitive. An oversized unit cools the air quickly, satisfies the thermostat and shuts off before it has removed the humidity. In the Gold Coast climate that leaves a room that is cold and clammy, and the short-cycling wears the compressor faster while using more energy than a correctly sized unit running steadily. Bigger is genuinely not better.",{"q":326,"a":327},"Why does the distance between the indoor and outdoor unit matter?","The refrigerant pipe run between them is a real cost, and it is not just the pipe. Longer runs need more refrigerant, more insulation, more labour, and eventually a larger capacity to overcome the losses. Where the pipe has to travel through finished walls, around a corner of the house or up to a second storey, both the labour and the making good increase. A head mounted on the wall directly opposite the outdoor unit is the cheapest possible case.",{"q":329,"a":330},"Do I need electrical work done before installing air conditioning?","Often, yes. Ducted systems and larger split systems generally require a dedicated circuit, and that needs a spare way and adequate capacity at the switchboard. Older boards frequently have neither. This is one of the more common reasons an installation quote comes in higher than an online estimate, which typically assumes the electrical supply is already in place.",{"q":332,"a":333},"Is it cheaper to install several split systems or one ducted system?","For one or two rooms, split systems are clearly cheaper. Once you are conditioning most of a house the comparison narrows, because multiple outdoor units, multiple pipe runs and multiple circuits add up while ducted spreads its fixed cost across the whole home. Ducted also tends to add more to property value. The right answer depends on how many rooms you actually want conditioned and whether you have the roof space.","\u002Fimages\u002Faircon.webp","A split system air conditioner installed in a Gold Coast home","air conditioning installation cost gold coast, split system installation cost, ducted air conditioning cost, aircon installation cost, what affects air conditioning cost",{},true,"\u002Fblog\u002Fair-conditioning-installation-cost-factors","air-conditioning-installation-cost-factors",{"title":5,"description":16},"What drives air conditioning installation cost on the Gold Coast: split vs ducted, capacity sizing, pipe runs, switchboard capacity and roof access.
