I'm pretty sure ConEd is overcharging me-- HELP! Okay, so I had everything unplugged for a 1-month work trip.  I suspected something was off with my bill, now I'm certain.  I received a higher than expected bill (by about $100), and an email notification saying that My A/C usage was 60% of my consumption.  How is this possible?  I'm not even there to turn the A/C on-- what gives?
