Update: Electric Bill

So I'm an East Coast girl. And back East, unless you have big bucks for some fancy schmancy luxury condo, you won't have central a/c or heating in your apartment. You'll have a small window unit for the summer and a radiator for the winter. My parents' house has central a/c and heating, but it was their job as the adults to make sure that the house stayed standing and functioning, and I didn't give much thought to any of it beyond turning off lights when I left the room and not leaving windows and doors open because "We're not cooling the whole neighborhood."

So this whole central a/c and heat thing is kind of new to me. And apparently, I should be having the filter replaced every 3 months or so. I've been in my apartment for 9 months. The filter has not been replaced that entire time.

I think we may have pinpointed the problem.

I don't wanna be a grown-up anymore.
