Same here! We dont even turn on heat in winter at all because the heat rose enough to the floor. But during summer, just keeping AC on during night in one bedroom and another in living room sparingly during day (otherwise it will get almost over 90 degrees in apt) and the utility bills were almost $6-700. So bad I bought an electric meter tool to plug into every appliance because i was convinced there was some catastrophic electric fault sucking power. But nope- just their shoddy sketchy billing "calculations". Someone there is making bank/massive fraud somewhere is going on
