Calculating your AC running expenses is important to come. Consumers nowadays try to look for low energy consuming products in the market, manufacturers have created ways to make their products energy efficient. This along with engineering advancements as introduced the Energy Efficiency Ratio (EER) ratings that we commonly see in today’s air conditioning units.
So, putting the EER in mind, a different accurate calculation is needed for new air conditioners today with energy star ratings:
(KW capacity/ EER) x price/ hour = price/ kWh
Using the previous example, if we calculate the cost to run a 2.5kW air conditioner, now with an EER of 3.21, then:
(2.5kW/ 3.21) x 28 c/ hour = 22 c/ kWh or $ 0.22/ kWh
Daily cost (on an 8-hour usage): 176 c or $ 1.76
Monthly cost: $ 52.80
How much does my air conditioner cost to run?
When calculating your AC running expenses you nee3d to know the size of your air con. A 2.5 kW air conditioner will cost about 22 cents an hour to run. Alternatively, a 9 kW air conditioner will cost $6.30 to run for 8 hours at full power. The table below shows you common sizes and cost associated with them.
