If you live in Sydney, you’ve probably wondered at least once: “How much does ducted air conditioning cost to run per hour in Sydney?” I asked the same question after installing a 14kW reverse cycle ducted system in my own home.
I’m part of the team at Air Conditioning Guys (ACG Sydney), based in Canterbury NSW. We specialise in residential ducted air conditioning installation and long-term performance testing.
Over the last 12 months, we tracked real electricity bills, used plug-in energy meters, and compared peak vs off-peak usage across multiple homes.
