Hi I've been having a/c problems for thelast 3 months in my apartment where the a/c won't cut off when I change the thermostat into the off position. I also notice that it won't cut off when in the auto position as well. To get it to cut off I have to play with the switch from off to heat to off to auto back and forth a few times... my electric bill is still over $100 for a 1 bedroom what gives
