We live in Bowling Green, Ohio and have a geothermal 6 ton unit, 4000 sqft home, 4800ft of loop in two (2) trenches foot 20 ft apart, 400ft long 5 ft deep. there are (8) eight pipes laid 4 on the bottom, 2 attached to each side of the trench about a foot up from the bottom of the trench, I have electric bill in the $400-$500 dollar range. I feel that this is high. Could I get some input from anyone, Please?

Questions:
