I have a 30 year old ranch style house w/ 2000 square feet and a 10 SEER, 5 ton a/c. The house has the same insulation it was built with.
Bill runs around $120 to $150 in the summer.
I have a programmable thermostat that goes up to 80 deg. at 7 am and starts to bring temp. down slowly starting at 3 pm till it gets to 72 at 10 pm.
