What affects the price
— System type. Split systems are cheapest installed; ducted mid-range; hydronic the premium option.
— New install vs replacement. Reusing existing ducts or pipework cuts thousands off the job.
— Home size & zones. More rooms means more outlets, radiators or split heads — and bigger central units.
— Fuel available. No natural gas connection pushes you to electric heat pumps or adds connection costs.
— Running costs. A cheaper unit to buy can be the dearest to run — efficiency ratings matter over years.
Tips before you post
— Gas appliances must be installed by a licensed gasfitter and electrical work by a licensed electrician.
— Reverse-cycle heat pumps are usually the cheapest heat per dollar to run in most of Australia.
— Get running-cost estimates alongside install quotes — the ten-year picture often changes the decision.
