Felt this. My roommate and I have window units but I use mine for an hour or two, max, during the worst days and just a regular fan otherwise. She blasts her A/C 24/7 (it’s been running non-stop for a week now and she’s not even here… long side story about why I won’t just go and turn it off). She’s going to be footing this bill for it because I have been the one to have to remind her to turn it and every light off, reminding her when our usual 50/50 payment is due, etc. and I’m done with it.
