Some Real Estate Agents are over stating the high and low electrical bill on new and existing homes in South Georgia . Buyers beware.
Instructions
1. Determine what fuel source powers your home's heating furnace and gather the utility bills for that fuel source, from both the winter months when the furnace was in use and for the summer months when it was not in use at all. For example; if you have a natural gas furnace, you would gather your natural gas utility bills for the summer months in which you did not use your furnace at all, and then those bills for the winter months in which the furnace was in use all month.
2. Take the winter monthly bills in which the furnace was in use all month and calculate the average. We will call this value "WCU," for winter cost of utility.
3. Take the summer monthly bills in which the furnace was not in use all month for that utility and calculate the average. We will call this value "SCU," for summer cost of utility.
4. Subtract the SCU value from the WCU value. We will call this value "AMHC," or average monthly heating cost. This is a result that is the average cost for actually heating your home per month with your furnace, and disregarding any effects on the bill from other uses of the utility, such as powering a hot water heater or clothes dryer.
5. Take the AMHC value and divide it by the square footage of your home. The resulting value will give you the cost per square foot to heat the home each month.
