This article explains how to calculate the actual cost of operating an air condtioning system in easy to understand language. This website answers most questions about air conditioning systems.

How Much Does It Cost to Run An Air Conditioner?In the previous section of this article we explained SEER ratings that measure air conditioning system efficiency, and we explained how we can determine how much energy an air conditioner uses either by the hour of by the season of use. At the end of that section we knew how much energy our air conditioner used, either on an hourly basis or for use during the whole cooling season. We were able to express the total air conditioning energy used in BTUs or in Kilowatts per hour or per season. Here we complete the process of translating air conditioner use into actual dollar costs. How Much Will It Cost Per Year to Run An Air Conditioner?In the United States for December 2007 the average retail price of electricity paid by residential consumers ranged from about $0.063 per kWh (Idaho) to $0.287 per kWh (Hawaii). Your electrical bill will indicate the current charge per kilowatt hour kWh of electricity you use. How to use the air conditioning cost formula: 500 kWh used per season x $0.25 = $125.00 - that's your electricity cost to run the air conditioner for a season. How Much Does It Cost Per Hour to Run An Air Conditioning SystemThis is an even simpler calculation. Using as an example information from our example air conditioner's data tag, ((5000 BTUh) / (10 SEER)) = 500 Wh 500 Wh x $0.25 = $0.12 per hour to run our air conditioner. Other Equations Using SEER RatingsWe can also write the SEER equation shown above as: SEER = BTUs / Watt-hours For more definitions of heating and air conditioning terms see SEER RATINGS & OTHER DEFINITIONS.
