This graph says it all!

I went from a small 10kW hours to, in four days, 52 kW hours. That day was over 90 degrees. On average, my summer usage is closer to 30kW hours a day. This puts me close to 1000 kW hours a month. When I finally decide to replace my Air Conditioner I hope to reduce that by 200kW hours. Since my current Air conditioning load appears to be about 500kW hours, I feel this is a reasonable number. Why? My current AC is a SEER 10. A new unit will have at least SEER 18. This would be almost a 100% increase. Thus reducing the usage by close to half.
