What is Air Conditioning Running Costs?

Air conditioning running costs encompass the ongoing expenses associated with operating an air conditioning system, primarily referring to the electricity consumed during its use. The term "running" specifically relates to the energy required to power the unit while it's in operation.

These costs significantly influence the lives of Australians, particularly during hot summers when air conditioning usage peaks. High running costs can strain household budgets and impact overall energy consumption patterns.

To calculate air conditioning running costs, use the following formula: (Wattage × Hours Used Per Day × Number of Days Used Per Year) ÷ 1000 × Electricity Rate per kWh

What is the Formula to Calculate Air Conditioning Running Costs?

The formula to calculate air conditioning running costs is: Cost = (Power consumption in kW × Hours of use × Electricity rate per kWh) ÷ 1000

For example, let's consider a Daikin FTXM35Q split system air conditioner:

• Power consumption: 1.00 kW
• Hours of use: 8 hours per day
• Electricity rate: $0.30 per kWh (average in Australia)

Daily cost = (1.00 × 8 × $0.30) ÷ 1000 = $2.40 per day
