How Much Does A Ducted Air Conditioning System Cost to Run 

This table reflects a more realistic operational scenario — the system runs only as much as needed (70%) during an average hour and could be much lower than this depending if the system has just been turned on, the indoor temperature is already at set temperature, there is a large differential between desired indoor temperature and outdoor temperature or there is minimal zones turned on

Power Cost Assumptions 

- Off-Peak: $0.23/kWH

- Shoulder: $0.27/kWh

- Peak: $0.36/kWh
