Bottom line is that the units never really shut off. it is the on and off cycles that kill the bills. When just idling they do not draw much current.. But anytime you start a motor it kicks a huge current spike .. if you do this 100 times a day it really hits your electric bill. What sort of amazes me is that we have not seen the major ac companies come out with a retrofit outside unit that runs as an inverter style and change out the inside coil as needed with something along the lines of a cap tube
