Question about Heating & Cooling
Hi, Yesterday I bought haier 12000 BTU air conditioner; I am wondering if I use it 24 hours a day, how much electricity is it going to cost?
12,000 BTU ( British Thermal Units ) converts to 3.5 kw/h.( kilowatts per hour or kilowatt hours )
3.5 kwh's x 24 = 84 kwh's per day. The average cost per kwh in the U.S. is near 13 cents per kwh, so as an example using these numbers .13 x 84 = $10.92 per day. x 30 = $327.60 per month. As mentioned in the previous solution, in order to get the most accurate estimate, you will need to find out what your local supplier charges per kwh. That information is printed on your utility bill.
As you might have guessed the per month figure can be significantly different depending largely on what your supplier charges.

To determine the cost of using this air conditioner, you will need to find out what your electric company charges per kw/h. This is the standard unit that electricity is charged for. Next determine the wattage of the air conditioner. This should be found on the unit name plate. If you can not find the wattage by the name plate, the take the voltage and multiply by the amperage, this will give you watts. Next multiply the wattage by 24. (watts per hour x 24 hours) Finally divide this number by 1000. This will give you the total Kw that the unit will use in a 24 hour period. If you multiply this number by the cost per Kw that will give you the operating cost of your unit for one day.
ex. electric company charges .25/Kw The unit uses 1000 watts 1000 x 24 = 24000 watts 24000/1000 = 24 Kw 24 Kw x .25/Kw = $6.00 day
Note: all figures shown above were randomly generated in my head, and have no correlation to your calculations. Hope this helps.
