Step 4. Multiply the air conditioner power consumption per hour times the number of hours the unit runs per day to determine the daily power usage by the air conditioner. If the air conditioner is used 10 hours per day, the daily power usage is 10 kilowatt-hours per day.tep 5. Multiply the kilowatt-hours used per day times the electricity rate charged by the power company. If you use 10 kilowatt-hours daily and the highest-tier rate you pay is 20 cents, the air conditioner costs $2.00 per day, or about $60 per month.
The efficiency at which air conditioners produce cooling is refered to as its SEER rating. SEER stands for Seasonal Energy Efficiency Ratio, and is a ratio of the amount of cooling produced (BTU) divided by the amount of electricity (watts) used.The higher the SEER, the greater the air conditionerâs efficiency.Older air conditioning systems have a SEER rating of 10 or under.EER stands for Seasonal Energy Efficiency Ratio, and is a ratio of the amount of cooling produced (BTU) divided by the amount of electricity (watts) used. The higher the SEER, the greater the air conditionerâs efficiency.
