How much does it cost to run a window air conditioner continuously?

Answer 1

Look at the manufacturers label for the air conditioner to determine the wattage rating. Use that to figure out how many watts per hour. For ease of comparison / math convert that number to kilowatts. Your electric company usually bills customers in kilowatt hours. Multiply the kilowatts for your AC unit times the hours per day and multiply that by the cost per kWh, divide by 100 (decimal placement) and you have your answer. Unit cost * kW * hours / 100=

For example a 1000 watt unit operated for 24 hours a day at a cost of 10 cents per kWh: 10*1*24/100= $2.40 a day, running continuously.

Answer 2

The cost of running a window air conditioner continuously depends on its wattage, the local electricity rate, and how many hours per day it's in use. On average, a window air conditioner with a 1,000-watt usage would cost around $0.10-0.20 per hour to run, totaling $2.40-$4.80 per day if used for 24 hours.
